Description

Sweetener and/or Sweetness Enhancer, Sweetener Compositions, Methods of Making the Same and Consumables Containing the Same

Field of the Invention

Background of the Invention The use of non-caloric high-intensity sweeteners is increasing due to health concerns raised over childhood obesity, type II diabetes, and related illnesses. Thus, a demand exists for sweeteners having sweetnesses significantly higher than those of conventional sweeteners, such as granulated sugar (sucrose) or high-fructose corn syrup (HFCS). Many non-caloric or low-caloric sweeteners, however, are prohibitively expensive and/or contain unpleasant off-flavors and/or have unexpected and less-than-desirable sweetness profiles.

Furthermore it is of interest to enhance desired flavor sensations, e.g., sweet taste, of non- caloric or low-caloric or standard (caloric) sweeteners, conventional or otherwise. Compounds that can enhance certain flavor sensations are of great interest and may allow not only improvement and/or intensification of the perceived flavor but also the ability to reach a certain flavor intensity using reduced concentrations of flavor ingredients. As one example, by employing an enhancer, less sweetener may be necessary to achieve a desired sweetness level, which may result in less calories and/or associated undesirable flavor notes/off-notes. Thus a need exists for sweetness enhancers. Non-caloric, high intensity sweeteners are known to have sweetness levels or "sweetnesses" that are significantly higher than those of conventional sweeteners. These non-caloric sweeteners often are added to the consumable products to replace at least a portion of the conventional caloric sweeteners, which results in a consumable product having a sweet flavor and a reduced amount of caloric sweetener. Acesulfame potassium is an exemplary non-caloric, high intensity sweetener.

In some instances, the caloric sweeteners and/or the non-caloric sweeteners are combined with other components, e.g., surfactants, emulsifiers, gums, or other sweeteners, to form sweetener compositions. These other components often improve the physical or chemical properties of the caloric or non-caloric sweetener. The sweetener compositions then may be incorporated into the respective consumable product. In most cases, the sweetener or the sweetness associated therewith is released from the consumable product quickly upon consumption of the consumable product. This release accounts for the sweetness realized by the consumer.

For some consumable products, e.g., chewing gum and other confections, once the consumable product begins to be consumed, it is desirable to have a prolonged release rate of sweetener from the consumable product. As a result, the sensation of sweetness is enjoyed by the consumer over a prolonged period of time. Conventional sweeteners, however, have been known to have more rapid release rates from the respective consumable product. As such, a majority of the sweetener is quickly released from the consumable product immediately upon consumption and very little sweetener then is left to be released during the remainder of the lifetime of the consumable product. As one example, a chewing gum comprising a conventional sweetener composition is often considered to be very sweet as the gum is initially chewed, but after some minutes of chewing, the gum is considered to be significantly less sweet.

Thus, a need exists for sweetener compositions that employ sweeteners, e.g., non-caloric, high intensity sweeteners, and that provide for prolonged release rates of these sweeteners from a consumable product to the palate of the consumer. As such, the sweetness associated with the sweetener composition may be recognized by the consumer over a longer period of time and result a prolonged sweetening sensation is realized by the consumer.

Detailed Description of the Invention Use of Nobiletin or a Derivative or a Hydrate thereof as a Sweetener and/or Sweetness Enhancer

As indicated above, there is a need for alternative (high intensity) sweeteners and sweetness enhancers which are healthy, i.e. non-caloric, non-cariogenic and ideal for diabetics as they would also allow reducing levels of conventional caloric sweeteners and therefore calorie reduction at the same sweetness level. Also, the need exists for sweeteners and sweetness enhancers having a pure taste, high sweetness and intensity, an excellent temperature and pH stability, excellent storage and solubility properties as well as a taste-enhancing effects and synergies when combined other sweetening compounds or food-related ingredients, e.g., pregelatinized starch. In particular, novel sweetness enhancers that are derived from natural products are of great interest. In addition, the need exists for sweetness enhancers that are free from off tastes, e.g. bitter or metallic tastes.

It is therefore an object of the present invention to provide an alternative sweetener and/or an alternative sweetness enhancer having the above mentioned desired characteristics.

It has now been found that nobiletin or a derivative or a hydrate thereof is useful as a sweetener and/or a sweetness enhancer.

Thus, in one aspect, the invention relates to the use of nobiletin or a derivative or a hydrate thereof as a sweetener and/or a sweetness enhancer. Nobiletin is a natural constituent. Nobiletin has been isolated from peel of king orange (Citrus nobilis), Seville orange (Citrus aurantium) and other Citrus spp., and the round kumquat (Fortunella japonica), also from Eupatorium coelestinum and Eupatorium leucolepis, see for example Robinson, R. et al., J.C.S., 1938, 1004, Schneider, G. et al., Arch.

Nobiletin has the chemical structure of the formula (I)

Methods for the synthesis of nobiletin are known; see for example Chen, W.M. et al., Indian J. Heterocycl. Chem., 1997, 6, 221-222.

The terms derivative and hydrate may also be used in conjunction with one another. For example, a nobiletin derivative may have a hydrate. Combinations of these terms are considered to be within the scope of the invention.

The amounts cited according to the present invention can also relate to the respective derivatives and hydrates.

As used herein, the term "enhance" means to have an effect on a particular flavor sensation in consumables or other products placed in the oral cavity which is found more pronounced (stronger, enhanced) in its taste intensity and/or which is found to have an earlier onset of the flavor sensation.

As used herein, the phrase "sweetness enhancer(s)" means any compound, which is capable of enhancing or intensifying the perception of sweet taste of sweetener compositions or sweetened compositions, e.g. nobiletin or a derivative or a hydrate thereof. The phrase "sweetness enhancer" is synonymous to the terms "sweet taste potentiator", "sweetness potentiator", and "sweetness intensifier". As used herein, the phrase "high intensity sweetener(s)" means any sweetener, which may in raw, extracted, purified, or any other from, singularly or in combination thereof have a sweetness potency greater than sucrose (common table sugar) yet have comparatively less calories. As used herein, the term "sweetener(s)" includes all artificial and natural sweeteners, sugar alcohols (or polyols) and sugar sweeteners (or carbohydrates). Artificial and natural sweeteners include but are not limited to abiziasaponin, abrusosides, in particular abrusoside A, abrusoside B, abrusoside C, abrusoside D, acesulfame potassium, advantame, albiziasaponin, alitame, aspartame, superaspartame, bayunosides, in particular bayunoside 1, bayunoside 2, brazzein, bryoside, bryonoside, bryonodulcoside, carnosifloside, carrelame, curculin, cyanin, chlorogenic acid, cyclamates and its salts, cyclocaryoside I, dihydroquercetin-3-acetate, dihydroflavenol, dulcoside, gaudichaudioside, glycyrrhizin, glycyrrhetin acid, gypenoside, hematoxylin, isomogrosides, in particular iso-mogroside V, lugduname, magap, mabinlins, micraculin, mogrosides (lo han guo), in particular mogroside IV and mogroside V, monatin and its derivatives, monellin, mukurozioside, naringin dihydrochalcone (NarDHC), neohesperidin dihydrochalcone (NDHC), neotame, osladin, pentadin, periandrin I-V, perillartine, D- phenylalanine, phlomisosides, in particular phlomisoside 1, phlomisoside 2, phlomisoside 3, phlomisoside 4, phloridzin, phyllodulcin, polpodiosides, polypodoside A, pterocaryosides, rebaudiosides, in particular rebaudioside A, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside F, rebaudioside G, rebaudioside H), rubusosides, saccharin and its salts and derivatives, scandenoside, selligueanin A, siamenosides, in particular siamenoside I, stevia, steviolbioside, stevioside and other steviol glycosides, strogines, in particular strogin 1, strogin 2, strogin 4, suavioside A, suavioside B, suavioside G, suavioside H, suavioside I, suavioside J, sucralose, sucronate, sucrooctate, talin, telosmoside A₁₅, thaumatin, in particular thaumatin I and II, trans-anethol, trans- cinnamaldehyde, trilobatin, D-tryptophane, and combinations thereof. Sugar alcohols (or polyols) include but are not limited to erythritol, galactitol, hydrogenated starch syrups including maltitol and sorbitol syrups, inositols, isomalt, lactitol, maltitol, mannitol, xylitol, and combinations thereof. Sugar sweeteners (or carbohydrates) include monosaccharides, disaccharides, oligosaccharides and polysaccharides such as but not limited to arabinose, dextrin, dextrose, fructose, high fructose corn syrup, fructooligosaccharides, fructooligosaccharide syrups, galactose, galactooligosaccharides, glucose, glucose and (hydrogenated) starch syrups/hydrolysates, isomaltulose, lactose, hydrolysed lactose, maltose, mannose, rhamnose, ribose, sucrose, stachyose, tagatose, trehalose, xylose, and combinations thereof. The sweeteners are known substances and are for example described by H. Mitchell (H. Mitchell, "Sweeteners and Sugar Alternatives in Food Technology", Backwell Publishing Ltd, 2006) and in WO 2009/023975 A2, each of which is incorporated herein by reference in its entirety.

Suitable hydrogenated starch hydrolysates include, but are not limited to, those disclosed in U.S. patent no. 4,279,931 and various hydrogenated glucose syrups and/or powders which contain sorbitol, maltitol, hydrogenated disaccharides, hydrogenated higher polysaccharides, or combination thereof. Hydrogenated starch hydrosylates are primarily prepared by the controlled catalytic hydrogenation of con syrups. The resulting hydrogenated starch hydrosylates are mixtures of monomelic, dimeric, and polymeric saccharides.

As shown in the Examples, the inventors have now surprisingly and unexpectedly found that nobiletin or a derivative or a hydrate thereof is useful as a sweetener and/or a sweetness enhancer. Nobiletin or a derivative or a hydrate thereof does not have the bitter aftertaste associated with saccharin, (for example, the bitter aftertaste associated with saccharin), or a metallic, acidic, astringent or throat-burning aftertaste (for example, those aftertastes often found in other high-intensity sweeteners) at the indicated concentration. In addition, nobiletin or a derivative or a hydrate thereof does not exhibit a liquorice aftertaste.

The excellent taste profile makes nobiletin or a derivative or a hydrate thereof desirable for use in consumables or other products placed in the oral cavity.

In another aspect, the invention relates to a sweetener composition comprising

(a) nobiletin or a derivative or a hydrate thereof.

Preferably, in the sweetener composition nobiletin or a derivative or a hydrate thereof is a sweetener and/or a sweetness enhancer, preferably a sweetness enhancer.

In a preferred embodiment the sweetener composition of the invention comprises

(b) at least one additional sweetener.

In one embodiment, the sweetener composition comprises a sweetener e.g., the at least one additional sweetener, which is selected from the group consisting of abiziasaponin, abrusosides, in particular abrusoside A, abrusoside B, abrusoside C, abrusoside D, acesulfame potassium, advantame, albiziasaponin, alitame, aspartame, superaspartame, bayunosides, in particular bayunoside 1, bayunoside 2, brazzein, bryoside, bryonoside, bryonodulcoside, carnosifloside, carrelame, curculin, cyanin, chlorogenic acid, cyclamates and its salts, cyclocaryoside I, dihydroquercetin-3 -acetate, dihydroflavenol, dulcoside, gaudichaudioside, glycyrrhizin, glycyrrhetin acid, gypenoside, hematoxylin, isomogrosides, in particular iso-mogroside V, lugduname, magap, mabinlins, micraculin, mogrosides (lo han guo), in particular mogroside IV and mogroside V, monatin and its derivatives, monellin, mukurozioside, naringin dihydrochalcone (NarDHC), neohesperidin dihydrochalcone (NDHC), neotame, osladin, pentadin, periandrin I-V, perillartine, D- phenylalanine, phlomisosides, in particular phlomisoside 1, phlomisoside 2, phlomisoside 3, phlomisoside 4, phloridzin, phyllodulcin, polpodiosides, polypodoside A, pterocaryosides, rebaudiosides, in particular rebaudioside A, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside F, rebaudioside G, rebaudioside H), rubusosides, saccharin and its salts and derivatives, scandenoside, selligueanin A, siamenosides, in particular siamenoside I, stevia, steviolbioside, stevioside and other steviol glycosides, strogines, in particular strogin 1, strogin 2, strogin 4, suavioside A, suavioside B, suavioside G, suavioside H, suavioside I, suavioside J, sucralose, sucronate, sucrooctate, talin, telosmoside A₁₅, thaumatin, in particular thaumatin I and II, trans-anethol, trans- cinnamaldehyde, trilobatin, D-tryptophane, erythritol, galactitol, hydrogenated starch syrups including maltitol and sorbitol syrups, inositols, isomalt, lactitol, maltitol, mannitol, xylitol, arabinose, dextrin, dextrose, fructose, high fructose corn syrup, fructooligosaccharides, fructooligosaccharide syrups, galactose, galactooligosaccharides, glucose, glucose and (hydrogenated) starch syrups/hydrolysates, isomaltulose, lactose, hydrolysed lactose, maltose, mannose, rhamnose, ribose, sucrose, tagatose, trehalose and xylose.

In another embodiment, the sweetener composition comprises a first additional sweetener and a second additional sweetener.

Preferably, one of the first additional sweetener and the second additional sweetener is fructose.

Preferably, the first additional sweetener is fructose.

Preferably, the at least one additional sweetener is a natural sweetener.

In another embodiment, the at least one additional sweetener is an artificial sweetener. In another embodiment, the sweetener composition comprises nobiletin or a derivative or a hydrate thereof in a purity of greater than about 60 % by weight, e.g., greater than about 70 % by weight, greater than about 80 % by weight, greater than about 90 % by weight, greater than about 98 % by weight, or greater than about 99 % by weight. Preferably, a 1 gram portion of the sweetener composition provides sweetness comparable to one to three teaspoons of granulated sugar, preferably comparable to two teaspoons of granulated sugar. For example, the compositions may contain sweetness comparable to that of granulated sugar (sucrose), and therefore can be used "spoon-for-spoon" or "cup-for-cup" in place of sugar. As used herein, the phrase "sweetness comparable" means that an experienced sensory evaluator, on average, will determine that the sweetness presented in a first composition is within a range of 80% to 120% of the sweetness presented in a second composition. The phrase "a sweetness comparable" relates to a determination ascertained by four or more experienced sensor evaluators in a sweetness matching test (designated hereinafter as "taste and spit assay"), as discussed below. Thus, for instance, 100 mg/ml of a sweetener composition comprising nobiletin provides "sweetness comparable" to 100 mg/ml of sucrose if the sweetener composition of the invention has a sweetness falling within the range of sweetness presented in 80-120 mg/ml of sucrose. The sweetness and/or sweetness enhancing properties of a compound, in some embodiments, can be identified by an in vitro in cell based assay as described in the Examples, in EP 1 865 316 Bl, which is incorporated herein by reference, or by field effector transistor technology of e.g. Alpha MOS. The taste of a sample of a compound, e.g, nobiletin, with regard to sweetness and/or sweetness enhancing properties, in other embodiments, may be assessed in vivo by using a panel of trained sensory evaluators experienced in the sweet taste estimation procedure, e.g. in the taste and spit assay as described e.g. in Example 2. In these cases, panelists are asked to take a sample of the liquid to be assessed (test substance, e.g. nobiletin or a derivative or a hydrate thereof) into the mouth and after some time allowed for taste perception to spit the sample out completely. Subsequently, the panelists are asked to rinse their mouth well with water or black tea to reduce any potential carry over effects. The tasting of a sample can be repeated if required.

In a first descriptive test (qualitative assessment for sweetness) the panelists are asked to taste the quality of single samples (maximum 3 subsequent samples). The individuals of the taste panel are asked to answer the following questions with regard to the quality of taste: 1) does the sample taste sweet?, 2) is there another taste detectable (bitter, sour, salty, umami)?, 3) is there an off- or aftertaste?, 4) is there anything else remarkable about the perception of the sample? In the next step (assessment of sweetness enhancing, e.g., fructose enhancing, features) the panelists are asked to answer questions in a pair wise comparison test to determine the enhancement of sweet taste of the test substance with fructose relative to fructose only. Again the panelists are given samples. Two samples are prepared for direct comparison regarding sweetness. One sample contains fructose in a solvent and the other sample additionally contains the test substance. Designation of the samples with A and B is randomized and is decoded after the taste procedure. The questions to be answered are: 1) does one sample taste sweeter than the other?, 2) if so, which one?, 3) are there any other differences in the taste between the two samples? The result of the taste and spit assay is a qualitative evaluation of the differences between the two samples.

In another embodiment, the sweetness and/or sweetness enhancing properties of the inventive sweetener composition, when dissolved in water, correspond to a particular degrees Brix, a well-known measurement of sugar content in an aqueous solution. In some embodiments, for example, when 5 grams of sweetener composition are dissolved in 95 grams of water, the resultant solution has a sweetness that corresponds to a degrees Brix value ranging from 1 to 1000, e.g., from 5 to 500 or from 5 to 100.

Preferably, one gram of the sweetener composition contains less calories and carbohydrates than about 1 gram of granulated sugar, e.g., less than about 0.5 grams of granulated sugar.

In another embodiment of the invention, the sweetener composition of the invention is substantially free of off-taste.

In one embodiment of the invention, the sweetener composition of the invention is liquid at ambient conditions.

In another embodiment of the invention, the sweetener composition of the invention is solid at ambient conditions.

In one embodiment of the invention, the sweetener composition of the invention comprises homogeneous particles comprising the sweetener and nobiletin or a derivative or a hydrate thereof. Preferably, the homogeneous sweetener particles have an average particle size of between about 50 microns and about 1250 microns, e.g., between about 100 microns and about 1000 microns. In another embodiment of the invention, the sweetener composition comprises a mixture of first particles comprising the sweetener and second particles comprising nobiletin or a derivative or a hydrate thereof. In one embodiment of the invention, the sweetener composition contains nobiletin or a derivative or a hydrate thereof as a sweetness enhancer. In this embodiment, the sweetener composition of the invention comprises from 0.0005 wt% to 1.0 wt% of nobiletin or a derivative or a hydrate thereof, based on the total weight of the sweetener composition, preferably from 0.0001 wt% to 0.1 wt%, particularly preferred from 0.001 to 0.05 wt%.

In another embodiment of the invention, the sweetener composition contains nobiletin or a derivative or a hydrate thereof as a sweetener and optionally as a sweetness enhancer. In this embodiment, the sweetener composition of the invention comprises from 3 wt% to 20 wt% of nobiletin or a derivative or a hydrate thereof, based on the total weight of the sweetener composition, preferably from 5 wt% to 15 wt%.

In one embodiment, the sweetener compositions further comprise at least one additional sweetness enhancer, e.g., at least two or at least three. Suitable additional sweetness enhancers are well known in the art. In one embodiment, the at least one additional sweetness enhancer may be selected from the group consisting of terpenes (such as sesquiterpenes, diterpenes, and triterpenes), fiavonoids, amino acids, proteins, polyols, other known natural sweeteners (such as cinnamaldehydes, selligueains and hematoxylins), secodammarane glycosides, and analogues thereof.

Additional exemplary sweetness enhancers include rebaudioside C, rebaudioside F, rebaudioside D, 13- [(2-0-p-D-glucopyranosyl-3-0-P-D-glucopyranosyl]-P-D- glucopyranosyl)oxy]- 17-hydroxy-kaur- 15-en-l 8-oic acid P-D-glucopyranosyl ester, 13- [(2-0-(3-0-P-D-glucopyranosyl)-P-D-glucopyranosyl-3-0-P-D-glucopyranosyl-P-D- glucopyranosyl)oxy] kaur-16-en-l 8-oic acid P-D-glucopyranosyl ester, and Rubusoside. Further for example, the at least one sweetness enhancer is chosen from rebaudioside A, stevioside, rebaudioside D, rebaudioside E, mogroside V, mogroside IV, brazzein, and monatin.

In one embodiment, the at least one sweetness enhancer is present in an amount at or below the sweetness detection threshold level of the at least one sweetness enhancer. In some embodiments, the at least one sweetness enhancer is present in an amount below the sweetness detection threshold level of the at least one sweetness enhancer. The sweetness detection threshold level can be specific for a particular compound. However, generally, in some embodiments, the at least one sweetness enhancer is present in an amount ranging from 0.5 ppm to 1000 ppm. For example, the at least one sweetness enhancer may be present in an amount ranging from 1 ppm to 300 ppm; and at least one sweetness enhancer may be present in an amount ranging from 0.1 ppm to 75 ppm; and at least one sweetness enhancer may be present in an amount ranging from 500 ppm to 3,000 ppm.

As used herein, the terms "sweetness threshold," "sweetness recognition threshold," and "sweetness detection threshold" are understood to mean the level at which the lowest known concentration of a certain sweet compound that is perceivable by the human sense of taste and it can vary from person to person. For example, a typical sweetness threshold level for sucrose in water can be 0.5%. Further for example, the at least one sweetness enhancer to be used can be assayed in water at least 25% lower and at least 25% higher than the sucrose detection level of 0.5% in water to determine the sweetness threshold level. A person of skill in the art will be able to select the concentration of the at least one sweetness enhancer so that it may impart an enhanced sweetness to a composition comprising at least one sweetener. For example, a skilled artisan may select a concentration for the at least one sweetness enhancer so that the at least one sweetness enhancer does not impart any perceptible sweetness to a composition that does not comprise at least one sweetener. In some embodiments, the compounds listed above as sweeteners may also function as sweetness enhancers. Generally speaking, some sweeteners may also function as sweetness enhancers and vice versa.

In one embodiment, the sweetener composition as defined above comprises

(c) a pregelatinized starch.

It has now been found that the inventive combination of nobiletin or a derivative or a hydrate thereof, if appropriate at least one additional sweetener, and pregelatinized starch provides for a sweetener composition that, when utilized in combination with a consumable product, demonstrates a prolonged release rate of nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener from the consumable product.

Preferably, the at least one additional sweetener is acesulfame potassium. Acesulfame potassium is a commercially available high intensity sweetener. One suitable commercial acesulfame potassium product is Sunett® from Nutrinova Nutrition Specialties & Food Ingredients. In one preferred embodiment, the at least one additional sweetener comprises sucrose, which is commercially available.

Without being bound by theory, it is believed that nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener possess characteristics that provide for prolonged release rates when nobiletin or a derivative or a hydrate thereof is employed in combination with the pregelatinized starch. As one particular example, acesulfame potassium has a particular solubility that, unexpectedly, allows the acesulfame potassium to effectively load onto the pregelatinized starch. In one embodiment, paraffin may be employed to introduce other types of sweeteners/flavors onto the pregelatinized starch. Paraffin, surprisingly, may provide for improvements in loading and, subsequently, prolonged release rates.

Pregelatinized starches are known commodities. As one example, WO 89/04842 discloses amylase treated granular starches that provide a microporous matrix material adapted for absorption and releasable containment of functional compositions. The microporous starch granules are chemically derivatized to enhance absorption and structural properties. Absorbed functional substances are released from the microporous starch matrix under the influence of mechanical compression, by diffusion into a surrounding fluid or as a result of degradation of the granular starch matrix. Also, WO 2009/103514 discloses a liquid loaded starch material comprising a solid carrier material consisting of pregelatinized, nongranular starch material, which consists of flake-shaped starch particles, wherein the size distribution of the starch particles is such that at least 50% by weight of the starch particles have a particle size of between 100 and 375 μπι, and wherein the BET specific surface area is less than or equal to 0.5 m²/g and one or more liquid components. This reference also provides for the use of same in food and animal feed products, pharmaceuticals, nutraceuticals, agrochemicals, and cosmetic or personal care products. The reference also provides a process for preparing said powdered liquid-loaded starch material. In addition, US 5,919,486 discloses a "liquid oil and fat ingredient or others" that are carried by pores of a porous carrier composed of porous starch grain obtained by reacting an enzyme having raw starch digestive activity "onto the starch." These references, however, do not disclose the combination of pregelatinized starches with sweeteners, e.g., non-caloric, high intensity sweeteners, such as acesulfame potassium. The references mentioned above are hereby incorporated by reference.

In one embodiment, the sweetener composition demonstrates a prolonged release rate from the consumable. In one embodiment, the consumable comprises the sweetener composition and the sweetener composition provides for an initial sweetness level. Sweetness levels, e.g., "sweetnesses," may be determined by tasting panels, as discussed above. Over time, as the consumable product continues to be consumed, the initial sweetness level decreases to a reduced sweetness level. In preferred embodiments, the initial sweetness level is essentially maintained over time. In one embodiment, the inventive sweetener composition releases from the consumable product over a prolonged time period. Preferably, the inventive sweetener releases from the consumer product over a time period that is at least 5% longer than the time period for a conventional sweetener composition (employed in similar amounts and in a similar consumable product) that does not comprise pregelatinized starch, e.g., at least 10% longer, at least 20% longer, at least 30% longer, or at least 50% longer.

In one embodiment, a level of mouthfeel of the sweetener composition is prolonged by the addition the pregelatinized starch. In one embodiment, when employed in a chewing gum, the inventive sweetener composition will provide a bulkier and/or a heavier final chewing gum.

In preferred embodiments, the sweetener composition comprises from 80 wt% to 95 wt% pregelatinized starch based on the total weight of the sweetener composition, e.g., from 82 wt% to 93 wt% or from 85 wt% to 90 wt%. In terms of limits, the sweetener composition may comprise at least 80 wt% pregelatinized starch, e.g., at least 82 wt% or at least 85 wt%. In terms of upper limits, the sweetener composition may comprise less than 95 wt% pregelatinized starch, e.g., less than 93 wt% or less than 90 wt%.

In one embodiment, nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener are absorbed into the pregelatinized starch. In another embodiment, nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener are adsorbed onto the pregelatinized starch. The pregelatinized starch comprises a plurality of pores and capillaries. In a preferred embodiment, the sweetener is disposed in these pores and/or capillaries. Exemplary disposition methods are discussed below.

In another embodiment, the present invention relates to a method of controlling the release rate of taste sensations associated with nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener. The taste sensations may be for example the sweetness provided by nobiletin or a derivative or a hydrate thereof, or if appropriate the at least one additional sweetener. In these embodiments, nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener are a component of a sweetener composition. The method comprises the step of contacting, e.g., admixing, nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener, e.g., the sweetener in the sweetener composition, with a pregelatinized starch to form a release controlled sweetener composition. The release controlled sweetener composition has a prolonged release rate, as compared to a similar sweetener composition that does not include the pregelatinized starch.

Pregelatinized Starch

The pregelatinized starch may vary widely and many pregelatinized starches are known in the art. Examples include the pregelatinized starches disclosed in US 5,919,486, WO 89/04842, WO 2007/110645, and WO 2009/103514. The shape of the pregelatinized starch particles may vary widely. For example, the pregelatinized starch may be granular. In some cases, small particles sizes and/or irregular particle shapes may correlate with a high specific surface area, which in turn correlates with a high loading capacity. Thus, in some embodiments, small particles with a high specific surface area may be used for the purpose of supporting the nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener(s).

In another embodiment, the starch may be non-granular. Preferably, the starch may be in the form of flakes. In one of these embodiments, the flake-shaped starch particles have a particle size ranging from 50 μπι to 500 μπι, e.g., from 100 μηι to 375 μπι, as determined by sieve analysis. In one embodiment, the flake-shaped starch particles are relatively large particles, and the BET specific surface area is as low as 0.5 m²/g or less, e.g., 0.4 m²/g or less, less than 0.3 m²/g. In terms of ranges the flake-shaped particles may have a specific surface area ranging from 0.05 m²/g to 0.5 m²/g, e.g., from 0.05 m²/g to 0.4 m²/g. In one embodiment, the inventive sweetener compositions comprise both granular pregelatinized starch and flake pregelatinized starch.

In one embodiment, the pregelatinized starch, whether it is in granular or flake form, may have a high porosity. In one embodiment, the pregelatinized starch, whether it is in granular or flake form, has a loading capacity greater than 10%, e.g., greater than 20%. In terms of upper limits, the pregelatinized starch, whether it is in granular or flake form, has a loading capacity less than 90%, e.g., less than 60%. The loading capacity may range from 10% to 90%, e.g., from 10% to 60%.

Without being bound by theory, the pregelatinized starches utilized in the present invention possess features and properties that are distinct from typical starches and/or bulking agents. Because conventional bulking agents lack the features and properties of the pregelatinized starches, these conventional bulking agents, when combined with sweeteners, would not be expected to provide the surprising and unexpected release rates demonstrated by the sweetener compositions of the present invention. The term "pregelatinized starch", as used herein, relates to a starch that has been chemically and/or mechanically and/or thermally treated in the presence of water to decrease the number and size of crystalline regions and increase the randomness in the general structure, and has been subsequently dried. Typically, the structural changes induced by gelatinization are manifested in the loss of birefringence and/or Maltese crosses in polarized light. The pregelatinized starches may or may not have lost their granular structure and are substantially soluble in cold water without cooking. In accordance with the present invention, "pregelatinized starches" may also be chemically modified to impart desirable properties, such as flowability, hydrophobicity and the like. Preferably, the pregelatinized starch used in the present invention is not chemically modified. Furthermore, the term "pregelatinized starch" may also include partially pregelatinized starch (PPS), which contains soluble (gelatinized) and insoluble fractions. Preferably, the pregelatinized starch used in the present invention is completely or predominantly pregelatinized, i.e. with less than 10%, preferably less than 5%, in particular less than 2% or 1% by weight, of crystalline regions.

In accordance with the present invention, the term "chemically modified starches" or "chemical modification" of starches includes, but is not limited to, crosslinked starches, starches modified with blocking groups to inhibit retrogradation, starches modified by the addition of lipophilic groups, acetylated starches, hydroxyethylated and hydroxypropylated starches, inorganically esterified starches, cationic, anionic and oxidized starches, zwitterionic starches, starches modified by enzymes, and combinations thereof.

Suitable pregelatinized starches for use herein can be derived from any native source, wherein native relates to the fact that said starch is found in nature. Typical sources for the starches are cereals, tubers, roots, legumes, fruit starches and hybrid starches. Suitable sources include, but are not limited to, corn, pea, potato, sweet potato, sorghum, banana, barley, wheat, rice, sago, amaranth, tapioca, arrowroot, carina, and low amylose (containing no more than about 10% by weight amylose, preferably no more than 5%) or high amylose (containing at least about 40% by weight amylose) varieties thereof. Also suitable are starches derived from a genetically modified starch crop. A preferred starch for use herein has an amylose content below 40%, including waxy corn starch with less than 1% amylose content. Particularly preferred starches include rice, wheat, tapioca, corn, and potato starches, in particular corn (maize) starch. A "granular shape" is intended to mean a roughly spheroid or ellipsoid shape and includes spherical particles that have indentations in one or more portions thereof, such as the spherical starch particles produced by a conventional spray-drying process. A "nongranular starch material", as used herein, refers to a starch material consisting of particles that do not have a granular shape. A "flake- shaped" or a "flaked" starch particle, when used herein, is a particle that does not have a granular structure and has a heterogeneous shape in the form of irregular flat or thick plates or sheets. Typically, roll-drying or drum- drying processes generate such flake-shaped starch particles. Other processes, however, may be employed to provide the flake-shaped particles.

In preferred embodiments, at least 80 wt%, e.g., at least 90 wt%, at least 95 wt%, or 100 wt% by weight of the starch particles have a particle size of between 50 μηι and 500 μπι, e.g., from 125 μπι and 350 μπι, between 125 μπι and 325 μπι, or between 125 μηι and 300 μηι.

A particularly preferred pregelatinized, non-granular starch material has a particle size of 100 μηι to 375 μπι for at least 50% by weight, preferably 80% by weight, of the starch particles, and a BET specific surface area of less than or equal to 0.5 m²/g, preferably less than or equal to 0.4 m²/g.

In one embodiment, the pregelatinized starch has a calorie content similar to that of sucrose.

A preferred commercial pregelatinized starch is Starrier R™ and similar products from Cargill.

In one embodiment, the pregelatinized, starch, whether in granular or flake form, may include minor amounts of one or more additives, preferably in a total amount of no more than 10% by weight, more preferably no more than 5% by weight, most preferably 0% to 1% by weight, based on the total weight of the pregelatinized starch. These optionally present additives may be added to the starch slurry or paste used for preparing the pregelatinized starch material of the present invention. Examples of additive include, but are not limited to, processing aids, such as agents for enhancing the formation of bubbles, surfactants and emulsifiers, and other ingredient, such as salts, sugars, fat, gums and hydrocolloids. In some embodiments, the additives included in the pregelatinized starch material may also be substances that have been added to the formed pregelatinized starch material to provide it with desirable properties. An example thereof is a surface modifying agent, which changes the absorption properties of the starch to improve, for example, the absorption of hydrophobic ingredients like oils and fats.

Preferably, the pregelatinized starch material is produced by a roll-drying or drum-drying process. Roll-drying as well as drum-drying involve the heating of an aqueous starch slurry or paste to gelatinize the starch and to instantaneously remove the moisture. The aqueous starch slurry or paste may be first heated and subsequently dried or, more preferably, the starch may be simultaneously gelatinized by heating and dried using a commercially available drum-dryer or roll-dryer apparatus. As used herein, the term "roll- drying" refers to a process where an aqueous starch slurry or paste is cooked or partially cooked and passed on heated rolls (sometimes also referred to as "drums") for drying or, preferably, a process where the aqueous starch slurry or paste is simultaneously cooked and dried on heated rolls. The term "drum-drying", when used herein, refers to a process very similar to the roll-drying process, except that a thicker coating of the starch slurry or paste is applied to heated drums.

In one embodiment, a process for preparing the pregelatinized starch material described hereinabove starts with mixing starch (generally in the form of a starch powder) and water to prepare an aqueous starch slurry or paste having a certain solids content. A starch "slurry or paste" may also include high-viscosity starch preparations, such as a moist filter cake. Suitable starches are as defined above. The starch content typically ranges from 20 wt% to 45 wt% by weight, e.g., from 25 wt% to 40 wt%% by weight, or from 32 wt% to 40 wt%. The prepared aqueous starch slurry or cake may then be applied onto heated, rotating rolls or drums of a roll-dryer or drum-dryer, conveniently by means of application drums or feed rolls, to simultaneously gelatinize and dry the aqueous starch slurry or paste. After one rotation, the obtained dried starch film is removed from the rolls or drums by a scrapping mechanism, such as a knife blade, to obtain a starch material, which is then subjected to grinding or milling, for example in a rotor beater mill or cutting mill. Finally, the ground (milled) starch material is sieved using one or several sieves of different mesh sizes, as known in the art, to obtain the desired sieve fraction of the pregelatinized, nongranular starch material. Suitable roll-dryers and drum-driers for preparing the pregelatinized, non-granular starch material of the present invention are commercially available, for example from GMF- Gouda (The Netherlands). Typically, they are designed as indirect dryers, where heat is transferred by pressurized stream to the inside (metal) drum wall, which in turn transfers the heat to the aqueous starch slurry or paste on the other side of the wall. While the basic construction is relatively simple, there are numerous configurations commercially available, which differ in the arrangement and number of drums and feed rolls, the type of scrapping mechanism, etc. Factors, such as the composition of the aqueous slurry or paste, the roll or drum temperature, and the drum or roll speed (which determines the residence time), will have an effect on the physical and chemical properties of the final pregelatinized, non-granular starch material. It is within the scope of the invention to or adjust process parameters to obtain a pregelatinized starch material having desirable properties. For example, different types of starches are known to have varying gelatinization temperatures and thus one or more of the above parameters may be adjusted and optimized to achieve a satisfactory result. Such optimizations are well within the normal capabilities of a person skilled in the art of drum-dried or roll-dried pregelatinized starches. The rolls or drums are typically heated to have a surface temperature in the range from 120 °C to 200 °C, e.g., from 140 °C to 190 °C, or from 150 °C to 180 °C. The rolls or drums are normally operated at a speed or rotation rate of 5 to 18 rpm, e.g., 5 to 15 rpm, or 8 to 13 rpm. One or more additional constituents (additives) may be admixed to the aqueous starch slurry or paste including, but not limited to, processing aids, such as bubble-forming agents, surfactants and emulsifiers, and other substances, such as salts, sugars, fat, gums, and hydrocolloids to improve certain properties. For example, the starch slurry or paste applied to the heated rolls or drums gets transformed into a continuous phase of melted starch that includes variable amounts of air bubbles. In order to obtain a pregelatinized starch material with an increased absorption capacity, conditions might be chosen to result in a relatively low bulk density, for example, by adding specific processing aids to the aqueous starch slurry or paste to increase formation of bubbles. Furthermore, it is also within the scope of the present invention, that the obtained roll-dried or drum-dried, pregelatinized, non- granular starch material is additionally treated with a surface modifying agent to change the absorption properties of the starch. A hydrophobic agent, for example, will further improve the absorption capacity for hydrophobic liquid components, like oils and fats.

Exemplary methods to assess the physical characteristics of the pregelatinized starch provided in the examples follow. (1) Particle size distribution

The particle size distribution of starch samples was determined by a sieve analysis using sieves with different openings. The respective sieve fractions on the sieves were weighted and divided by the total weight of the starch sample to give a percentage retained on each sieve.

(2) Particle shape

The particle shape of starch samples was observed by scanning electronic microscopy at magnifications of 100 to 750 x, as known in the art.

(3) BET specific surface area

The specific surface area of starch samples was measured by nitrogen absorption in a Gemini II 2370 Surface Area Analyzer (Micromeritrics NV/SA, Brussels, Belgium). The multi-point (11 points by convention) BET-method (Bruauner, Emmett and Teller, J. Am. Chem. Soc. 60:309-319 (1938)) was used to determine the total available surface area.

Methods of Making a Sweetener Composition of the Invention and Enhancing the Sweetness of a Sweetener Composition

In another aspect, the present invention relates to a method of making a sweetener composition comprising the step of admixing a sweetener with nobiletin or a derivative or a hydrate thereof. In one embodiment, the method yields a composition comprising nobiletin or a derivative or a hydrate thereof nobiletin or a derivative or a hydrate thereof in the form of an extract or in isolated or purified form.

In one embodiment, the inventive method further comprises the step of combining nobiletin or a derivative or a hydrate thereof with at least one other additional ingredient chosen from bubble forming agents, bulking agents, carriers, fibers, sugar alcohols, oligosaccharides, sugars, high intensity sweeteners, nutritive sweeteners, flavoring, flavor enhancers, flavor stabilizers, acidulants, anti-caking, free-flow agents, and any combination thereof. Preferably, the composition comprises about 3 to about 200 mg of nobiletin or a derivative or a hydrate thereof per 1 gram of the composition, e.g., about 3 to about 100 mg of nobiletin or a derivative or a hydrate thereof per 1 gram of the composition, or about 5 to about 10 mg of nobiletin or a derivative or a hydrate thereof nobiletin or a derivative or a hydrate thereof per 1 gram of the composition.

In one embodiment, the invention relates to a method for enhancing the sweetness of a sweetener composition comprising a sweetener, comprising the step of adding to the sweetener nobiletin or a derivative or a hydrate thereof to form an enhanced sweetener composition. Preferably, nobiletin or a derivative or a hydrate thereof is added in amount effective to increase the sweetness of the sweetener composition to an increased sweetness level. In preferred embodiments, the increase sweetness level is greater than an initial sweetness level of a comparative sweetener compositionally the same as the aforementioned sweetener composition of the invention but without nobiletin or a derivative or a hydrate thereof.

In one aspect, the present invention relates to a method for preparing a sweetener composition comprising pregelatinized starch. The inventive method comprises the step of applying nobiletin or a derivative or a hydrate thereof and if appropriate at least one additional sweetener to the pregelatinized starch. In one embodiment, the inventive method comprises the step of combining, e.g., admixing, nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener with a pregelatinized starch to form a release controlled sweetener composition. For loading the pregelatinized starch material with nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener, the starch material may be placed in a vessel supporting mechanical mixing and preferable capable of being sealed. Suitable mixing devices are, for example, a paddle mixer, a ribbon blender, a V-blender, or a plough blade mixer. Nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener may then be supplied, for example poured, pumped or, preferably, sprayed via a nozzle, into the vessel and applied onto the agitated pregelatinized starch material. In some embodiments, nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener is supplied in the form of a sweetener mixture comprising nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener and a carrier. Spraying via a nozzle is advantageously used because the nozzle leads to the formation of small droplets that are more easily absorbed by the pregelatinized starch. Loading from the gas phase or under supercritical conditions is also possible. The mixing may be continued until an even distribution of the sweetener into and/or onto the pregelatinized starch is obtained. The time required for spraying or pumping is dependent upon the addition level of nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener onto the pregelatinized starch and the time required to ensure complete absorption to form a free flowing powder.

In one embodiment, the sweetener compositions of the present invention are formed by contacting the pregelatinized starch with a sweetener mixture comprising nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener and a carrier. Preferably, the carrier is glycerol, however ever other suitable carriers may be employed. Without being bound by theory, the pregelatinized starch has a plurality of pores and capillaries. Upon contacting the sweetener mixture with these pores and/or capillaries, nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener is distributed therein. Nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener that is disposed in the pores and/or capillaries may then be released, e.g., released at a prolonged rate, as pressure is applied to the sweetener composition or to the consumable product that comprises the composition, e.g., via chewing. Another suitable method for loading nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener onto the pregelatinized starch material may be a fluidized-bed loading process. In such a process, the pregelatinized starch material is fluidized by forcing air or another gas upward through a bed of starch particles. Nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener are then sprayed via a nozzle onto the fluidized starch particles to yield a sweetener-loaded starch material of evenly loaded starch particles. Again, nobiletin or a derivative or a hydrate thereof, and if appropriate the at least one additional sweetener may be supplied in the form of a sweetener mixture comprising the sweetener and a carrier. A further suitable loading method for use herein comprises the steps of suspending the pregelatinized starch carrier material in nobiletin or a derivative or a hydrate thereof and if appropriate the at least one additional sweetener, e.g., in a sweetener mixture, followed by separating the powdered sweetener-loaded starch material from the liquid components by conventional separation methods, such as filtration or centrifugation.

Depending on the type of sweetener(s) to be loaded, the sweetener(s) may be heated or cooled. In case of high viscous liquid components, for example, it might be favourable to heat the sweetener(s) to decrease the viscosity and facilitate the loading process. In case of temperature-sensitive sweetener(s), cooling might be desired or required. Means for cooling or heating, such as a cooled or heated blender, are well-known to a person skilled in the art. In accordance with the present invention, the pregelatinized starch may be pre-treated before loading with an inert gas to remove, for instance, oxygen. The pregelatinized starch may also be vacuum-treated before loading to increase the absorption capacity. Further, when sensitive liquids are to be loaded, the loading operation might be carried out under an inert gas atmosphere, for example under a nitrogen atmosphere to protect against loss of quality by oxidation.

After having loaded the pregelatinized starch material with one or more sweetener(s), further processing steps may optionally follow. For example, flowing or anti-caking agents may be added to the sweetener-loaded starch material, such as tricalcium phosphate, silica, silicates and/or stearates, to increase flowability. The powdered sweetener-loaded starch material of the present invention may also be provided with a coat and/or further encapsulated by any suitable encapsulating or coating materials, such as maltodextrins, starches, modified starches, dextrins, oils, fats, waxes, hydrocolloids, proteins, as known in the art.

The inventive sweetener compositions may further comprise celluloses. As used herein, the term "cellulose" refers to any cellulosic material (other than the pregelatinized starches described herein) known to the skilled person. As indicated above, the pregelatinized starches of utilized in the present invention are different from conventional starches or celluloses and possess particular characteristics that provide for some of the features of the inventive sweetener composition. These characteristics are not present in all starches or cellulosic materials. Thus, it is not expected that conventional starches and/or celluloses would provide for the inventive features demonstrated by the present invention. In typical embodiments, the cellulose includes polysaccharides having linear chains of at least several hundred beta-linked D-glucose units. When obtained from commercial sources, for example, the cellulose may exist as a powder. Further, in some embodiments, the cellulose is insoluble or substantially insoluble in water. In other embodiments, when incorporated into a consumable product, the cellulose preferably will not detract substantially from the overall product dissolution. Chemically modified celluloses can be employed in the compositions of the invention provided the modifications do not result in water soluble material. The cellulose may have any particle size (or particle size distribution) that is suitable for use in a sweetener composition. For example, in some embodiments, the size of the cellulose particles may range from about 1 micron to about 400 microns, e.g., from about 3 microns to about 300 microns, from about 5 microns to about 200 microns, or from about 6 microns to about 100 microns. In some embodiments, the insoluble cellulose is a cellulose that if used in amounts exceeding 1 % in an aqueous medium can lead to significant viscosity change.

Formulations

In another aspect, the present invention relates to formulations of the sweetener composition.

In these formulations, the sweetener composition of the invention may take any suitable form including, but not limited to, an amorphous solid, a crystal, a powder, a tablet, a liquid, a cube, a glace or coating, a granulated product, an encapsulated form abound to or coated on to carriers/particles, wet or dried, or combinations thereof.

For example, in one embodiment, the sweetener composition formulations can be provided in pre-portioned packets or ready-to-use formulations, which include nobiletin or a derivative or a hydrate thereof. For example, in one embodiment, a single serving packet formulation (usually about a 1 gram portion) can provide sweetness comparable to that contained in two teaspoons of granulated sugar (sucrose). It is known in the art that a "teaspoon" of sucrose contains approximately 4 grams of sucrose.

In another embodiment, a volume of a ready-to-use formulation can provide sweetness comparable to the same volume of granulated sugar. Preferably, a single serving packet of the composition comprising nobiletin or a derivative or a hydrate thereof (e.g., 1 gram) can provide sweetness comparable to about 0.9 to about 9.0 grams of granulated sugar (sucrose). In another embodiment, 1 gram of the sweetener composition contains less calories and carbohydrates than about 1 gram of granulated sugar.

As used herein, the term "about" encompasses the range of experimental error that occurs in any measurement. Unless otherwise stated, all measurement numbers are presumed to have the word "about" in front of them if the word "about" is not expressly used. The formulation of the invention may contain further additives known to those skilled in the art. These additives include but are not limited to bubble forming agents, bulking agents, carriers, fibers, sugar alcohols, oligosaccharides, sugars, high intensity sweeteners, nutritive sweeteners, flavorings, flavor enhancers, flavor stabilizers, acidulants, anti-caking and free-flow agents. Such additives are for example described by H. Mitchell (H. Mitchell, "Sweeteners and Sugar Alternatives in Food Technology", Backwell Publishing Ltd, 2006, which is incorporated herein by reference in its entirety). As used herein, the term "flavorings" may include those flavors known to the skilled person, such as natural and artificial flavors. These flavorings may be chosen from synthetic flavor oils and flavoring aromatics and/or oils, oleoresins and extracts derived from plants, leaves, flowers, fruits, and so forth, and combinations thereof. Nonlimiting representative flavor oils include spearmint oil, cinnamon oil, oil of wintergreen (methyl salicylate), peppermint oil, Japanese mint oil, clove oil, bay oil, anise oil, eucalyptus oil, thyme oil, cedar leaf oil, oil of nutmeg, allspice, oil of sage, mace, oil of bitter almonds, and cassia oil. Also useful flavorings are artificial, natural and synthetic fruit flavors such as vanilla, and citrus oils including lemon, orange, lime, grapefruit, yazu, sudachi, and fruit essences including apple, pear, peach, grape, blueberry, strawberry, raspberry, cherry, plum, pineapple, watermelon, apricot, banana, melon, apricot, ume, cherry, raspberry, blackberry, tropical fruit, mango, mangosteen, pomegranate, papaya and so forth. Other potential flavors include a milk flavor, a butter flavor, a cheese flavor, a cream flavor, and a yogurt flavor; a vanilla flavor; tea or coffee flavors, such as a green tea flavor, a oolong tea flavor, a tea flavor, a cocoa flavor, a chocolate flavor, and a coffee flavor; mint flavors, such as a peppermint flavor, a spearmint flavor, and a Japanese mint flavor; spicy flavors, such as an asafetida flavor, an ajowan flavor, an anise flavor, an angelica flavor, a fennel flavor, an allspice flavor, a cinnamon flavor, a camomile flavor, a mustard flavor, a cardamom flavor, a caraway flavor, a cumin flavor, a clove flavor, a pepper flavor, a coriander flavor, a sassafras flavor, a savory flavor, a Zanthoxyli Fructus flavor, a perilla flavor, a juniper berry flavor, a ginger flavor, a star anise flavor, a horseradish flavor, a thyme flavor, a tarragon flavor, a dill flavor, a capsicum flavor, a nutmeg flavor, a basil flavor, a marjoram flavor, a rosemary flavor, a bayleaf flavor, and a wasabi (Japanese horseradish) flavor; alcoholic flavors, such as a wine flavor, a whisky flavor, a brandy flavor, a rum flavor, a gin flavor, and a liqueur flavor; floral flavors; and vegetable flavors, such as an onion flavor, a garlic flavor, a cabbage flavor, a carrot flavor, a celery flavor, mushroom flavor, and a tomato flavor. These flavoring agents may be used in liquid or solid form and may be used individually or in admixture. Commonly used flavors include mints such as peppermint, menthol, spearmint, artificial vanilla, cinnamon derivatives, and various fruit flavors, whether employed individually or in admixture. Flavors may also provide breath freshening properties, particularly the mint flavors when used in combination with cooling agents. A preferred flavoring is menthol and, in one embodiment, the inventive sweetener composition comprises acesulfame potassium, menthol, and pregelatinized starch. Flavors may also provide breath freshening properties, particularly the mint flavors when used in combination with cooling agents. These flavorings may be used in liquid or solid form and may be used individually or in admixture. Other useful flavorings include aldehydes and esters such as cinnamyl acetate, cinnamaldehyde, citral diethylacetal, dihydrocarvyl acetate, eugenyl formate, p- methylamisol, and so forth may be used. Generally any flavoring or food additive such as those described in Chemicals Used in Food Processing, publication 1274, pages 63-258, by the National Academy of Sciences, may be used. This publication is incorporated herein by reference.

Further examples of aldehyde flavorings include but are not limited to acetaldehyde (apple), benzaldehyde (cherry, almond), anisic aldehyde (licorice, anise), cinnamic aldehyde (cinnamon), citral, i.e., alpha-citral (lemon, lime), neral, i.e., beta-citral (lemon, lime), decanal (orange, lemon), ethyl vanillin (vanilla, cream), heliotrope, i.e., piperonal (vanilla, cream), vanillin (vanilla, cream), alpha-amyl cinnamaldehyde (spicy fruity flavors), butyraldehyde (butter, cheese), valeraldehyde (butter, cheese), citronellal (modifies, many types), decanal (citrus fruits), aldehyde C-8 (citrus fruits), aldehyde C-9 (citrus fruits), aldehyde C-12 (citrus fruits), 2-ethyl butyraldehyde (berry fruits), hexenal, i.e., trans-2 (berry fruits), tolyl aldehyde (cherry, almond), veratraldehyde (vanilla), 2,6- dimethyl-5-heptenal, i.e., melonal (melon), 2,6-dimethyloctanal (green fruit), and 2- dodecenal (citrus, mandarin), cherry, grape, strawberry shortcake, and mixtures thereof. These listings of flavorings are merely exemplary and are not meant to limit either the term "flavoring" or the scope of the invention generally.

In some embodiments, the flavoring may be employed in either liquid form and/or dried form. When employed in the latter form, suitable drying means such as spray drying the oil may be used. Alternatively, the flavoring may be absorbed onto water soluble materials, such as cellulose, starch, sugar, maltodextrin, gum arabic and so forth or may be encapsulated. The actual techniques for preparing such dried forms are well-known.

In some embodiments, the flavorings may be used in many distinct physical forms well- known in the art to provide an initial burst of flavor and/or a prolonged sensation of flavor. Without being limited thereto, such physical forms include free forms, such as spray dried, powdered, beaded forms, encapsulated forms, and mixtures thereof.

Tabletop Sweetener Compositions In another aspect, the present invention relates to tabletop sweetener compositions comprising nobiletin or a derivative or a hydrate thereof and to methods of manufacturing such tabletop sweetener compositions. "Tabletop sweetener," as used herein, refers to sweetener compositions that comprise at least one sweetener, and optionally, at least one sweetness enhancer, which can be used in the preparation of various food items and/or as an additive to food items. As one example, the tabletop sweetener may be used in the preparation of baked goods or other sweetened foods. As another example, the tabletop sweetener may be used to season, sweeten, or otherwise customize a prepared food item, e.g., beverages, fruit, or yoghurt. In a preferred aspect, the tabletop sweetener is in a crystalline, granulated, or powder form. In various aspects, the tabletop sweetener will comprise one or more sweeteners and/or one or more sweetness enhancers. In one embodiment, the tabletop sweetener may comprise either or both a caloric sweetener and/or substantially non-caloric sweeteners, and, if appropriate, one or more sweetness enhancers. Typical examples of caloric sweeteners that may be used in tabletop sweeteners include sucrose, fructose, and glucose. Common tabletop forms of these caloric sweeteners include cane sugar, bee sugar, and the like. In recent decades, substantially non-caloric sweeteners have gained popularity. In many instances, these sweeteners can be used as substitutes for caloric sweeteners and are often referred to as "sugar substitutes."

In many instances, sugar substitutes provide a greater sweetening effect than comparable amounts of caloric sweeteners, such as sucrose or fructose. Therefore, smaller amounts of sugar substitutes are required to achieve sweetness comparable to that of an amount of sugar. Sugar substitutes, however, typically have a taste profile that differs from sucrose or fructose. Such differences include, but are not limited to, increased astringency, bitterness, various aftertastes, delayed onset of sweetness, and different mouthfeel. Therefore, sugar substitutes are often formulated with other materials that can provide bulk and can enhance the taste profile to be more similar to that of sucrose or fructose. Thus, sugar substitutes have been formulated to create a tabletop sweetener formulation that has a bulk and a taste profile that is comparable to sucrose or fructose. Nevertheless, consumers can still distinguish the low-calorie sweetener formulations from caloric tabletop sweeteners. Therefore, if low-calorie tabletop sweeteners are to replace caloric tabletop sweeteners, formulations of low-calorie sweeteners must be continuously improved to meet consumer demand.

There is an increasing interest in such sweeteners containing natural ingredients. This interest stems partially from increasing consumer interest in such products, but also from the rise of retail and internet stores selling natural products, and requiring suppliers of such products to certify that natural ingredients are used in any products being supplied.

Therefore, there is a need for new tabletop sweetener formulations which are low in calories (or have no calories) and that can reasonably approximate the taste profile, mouthfeel, and texture of caloric sweeteners.

The invention, in another aspect, relates to a tabletop sweetener composition comprising

(c) nobiletin or a derivative or a hydrate thereof and

(d) a taste-improving amount of cellulose.

(a) a disaccharide carbohydrate and/or fructose;

(b) erythritol;

(c) nobiletin or a derivative or a hydrate thereof; and

(d) a taste-improving amount of cellulose.

In some embodiments of the invention, the tabletop sweetener composition comprises a disaccharide and contains no fructose. In other embodiments, the tabletop sweetener composition comprises fructose and does not contain disaccharide,. In other embodiments, the tabletop sweetener compositions comprise both a disaccharide and fructose.

As used herein, the term "disaccharide" refers to any sugar having two monosaccharide units. The monosaccharide units may exist as either ketones or aldehydes, and may have either a cyclic or acyclic structure. When a monosaccharide exists as a cyclic structure, the monosaccharide may exist as a hemiacetal or hemiketal, among other forms. Moreover, when a monosaccharide exists as a cyclic structure, either anomer is included within this definition. Illustrative monosaccharides include trioses, tetroses, pentoses, hexoses, heptoses, octoses, and nonoses. In forming a disaccharide, the monosaccharide units may bond to form either reducing disaccharides or non-reducing disaccharides.

As used herein, the terms "sugar alcohol(s)" or "polyol(s)" refer to sugar alcohols such as but not limited to erythritol, galactitol, hydrogenated starch syrups including maltitol and sorbitol syrups, inositols, isomalt, lactitol, maltitol, mannitol, xylitol, and combinations thereof.

As used herein, the term "erythritol" refers to a sugar alcohol well known to the skilled person. Erythritol, in either food grade or reagent grade is readily available through commercial sources.

As used herein, the term "cellulose" refers to any cellulosic material known to the skilled person. In typical embodiments, the cellulose includes polysaccharides having linear chains of at least several hundred beta-linked D-glucose units. When obtained from commercial sources, for example, the cellulose may exist as a powder. Further, in typical embodiments, the cellulose is insoluble or substantially insoluble in water; yet, in an application like tabletop sweeteners, when incorporated in such an application, it preferably will not detract substantially from the overall product dissolution. Chemically modified celluloses can be employed in the compositions of the invention provided the modifications do not result in water soluble material. The cellulose may have any particle size (or particle size distribution) that is suitable for use in a sweetener composition. For example, in some embodiments, the size of the cellulose particles may range from about 1 micron to about 400 microns, e.g., from about 3 microns to about 300 microns, from about 5 microns to about 200 microns, or from about 6 microns to about 100 microns. In some embodiments, the insoluble cellulose is a cellulose that if used in amounts exceeding 1% in an aqueous medium can lead to significant viscosity change.

In some embodiments of the invention, a "taste-improving amount" of cellulose is used. This "taste-improving amount" refers to an amount of cellulose that imparts an unexpected improvement in the taste profile of sweetener compositions of the invention. In some instances, for example, the taste improvement may be perceived as an enhancement in the sweetness of the sweetener composition or of the beverage or foodstuff containing the sweetener composition. In other instances, for example, the taste improvement may be perceived as a reduction or masking of the bitterness of the sweetener composition or of the beverage or foodstuff containing the sweetener composition. The taste improvement may also be a combination of both sweetness enhancement and bitterness reduction. In some embodiments of the sweetener compositions, the taste-improving amount of cellulose ranges from about 0.4 % by weight to about 3.0 % by weight, e.g., from about 0.7 % by weight to about 2.0 % by weight, of cellulose, based on the total weight of the sweetener composition. In some embodiments, the sweetener composition contains about 1 % by weight cellulose, based on the total weight of the sweetener composition.

In one embodiment, the disaccharide includes, but is not limited to, disaccharides containing glucose, fructose, and galactose. In another embodiment, the disaccharide carbohydrate includes, but is not limited to isomaltulose, lactose, maltose, sucrose, and trehalose. In another embodiment, the disaccharide is isomaltulose.

In a preferred embodiment of the invention, the disaccharide is selected from the group consisting of isomaltulose, lactose, maltose, sucrose, and trehalose.

Sweetener compositions of the invention may contain varying amounts at least one sugar sweetener, in particular of a disaccharide and/or fructose, of at least one sugar alcohol, in particular of erythritol, of nobiletin or a derivative or a hydrate thereof and of cellulose. The desired amount of nobiletin or a derivative or a hydrate thereof may vary depending on, among other factors, the desired use of the tabletop sweetener composition, the presence or absence of other components in the tabletop sweetener composition, the identity of any sugar sweetener, in particular of any disaccharide, if present, and the presence or absence of fructose.

In some embodiments, the tabletop sweetener composition contains from about 40 % by weight to about 70 % by weight sugar alcohol, in particular erythritol, based on the total weight of the sweetener composition, e.g., from about 50 % by weight to about 60 % by weight, from about 55 % by weight sugar alcohol, in particular to about 65 % by weight, from about 57 % by weight to about 63 % by weight, or from about 60 % by weight to about 62 % by weight. In some embodiments, the sweetener composition contains about 55 % by weight erythritol, based on the total weight of the sweetener composition. In still other embodiments, the sweetener composition contains about 61-62 % by weight sugar alcohol, in particular erythritol, based on the total weight of the sweetener composition.

In some embodiments, the tabletop sweetener composition contains from about 27 % by weight to about 50 % by weight sugar sweetener, in particular disaccharide, based on the total weight of the tabletop sweetener composition, e.g., from about 35 % by weight to about 45 % by weight from about 30 % by weight to about 40 % by weight, from about 30 % by weight to about 38 % by weight, from about 32 % by weight to about 36 % by weight, or from about 33 % by weight to about 35 % by weight. In some such embodiments, the tabletop sweetener composition contains about 41 % by weight sugar sweetener, in particular disaccharide, based on the total weight of the sweetener composition.

In a preferred embodiment, the sugar sweetener is isomaltulose.

In some embodiments, the sweetener composition contains from about 0.5 % by weight to about 7.0 % by weight nobiletin or a derivative or a hydrate thereof, based on the total weight of the sweetener composition, e.g., from about 0.7 % by weight to about 5.0 % by weight, or from about 1.0 % by weight to about 2.5 % by weight. The amount of nobiletin or a derivative or a hydrate thereof used may in certain situations depend on the purity of the material.

In another embodiment, tabletop sweetener compositions of the invention contain (a) from about 38 % by weight to about 43 % by weight of isomaltulose; (b) from about 50 % by weight to about 60 % by weight erythritol; (c) from about 0.75 % by weight to about 1.75 % by weight nobiletin or a derivative or a hydrate thereof; and (d) from about 0.5 % by weight to about 1.5 % by weight cellulose; based on the total weight of the tabletop sweetener composition.

Tabletop sweetener compositions of the invention may also contain amounts of other ingredients in addition to sugar sweetener, in particular in addition to disaccharide and/or fructose, the sugar alcohol such as erythritol, nobiletin or a derivative or a hydrate thereof and cellulose. Such additional ingredients include, but are not limited to, sweetness modifiers, mouthfeel enhancers, flavorings (e.g., vanilla flavoring), and the like. Honey and/or evaporated cane juice may be used in place of or in combination with the sugar alcohol, in particular in place of or in combination with erythritol. Natural flavors and other ingredients are preferred when the product is to be labeled as "all-natural."

In another embodiment, the tabletop sweetener composition comprises less than about 2 % by weight of a sweetness modifier, e.g., less than about 1% by weight. In terms of ranges, the tabletop sweetener composition may, for example, comprise between about 0.01 % by weight and about 2 % by weight sweetness modifier, in particular between about 0.1 % by weight and about 1.5 % by weight sweetness modifier. In another embodiment, the tabletop sweetener composition comprises less than about 1 % by weight of a mouthfeel enhancer, e.g., less than about 0.5% by weight. In terms of ranges, the tabletop sweetener composition may, for example, comprise between about 0.01 % by weight and about 1 % by weight mouthfeel enhancer, in particular between about 0.1 % by weight and about 0.5 % by weight mouthfeel enhancer.

In another embodiment, the tabletop sweetener composition comprises less than about 1 % by weight of a flavoring, e.g., less than about 0.5% by weight. In terms of ranges, the tabletop sweetener composition may, for example, comprise between about 0.01 % by weight and about 1 % by weight flavoring, in particular between about 0.1 % by weight and about 0.5 % by weight flavoring.

In some embodiments, sweetener compositions of the invention provide at least one, if not more than one, of the following desirable characteristics: (a) fewer calories per gram than standard table sugar; (b) fewer calories than an amount of standard table sugar perceived as providing comparable sweetness; and (c) lower glycemic index than that of standard table sugar. In some embodiments, the sweetener composition has less than about 5 calories/gram, or less than about 3 calories/gram, or less than about 1 calorie/gram. As used herein, the term "calorie" refers to the unit of energy commonly appearing on the packaging of food and/or beverage items sold in the United States. The term, as such, does not refer to 1 cal. of energy, but rather corresponds to approximately 1 kcal. of energy. In a typical tabletop sweetener application, for example, the sweetener composition can be packaged in a form where it provides a similar sweetness to about 7 grams of sucrose, preferably 5 g of sucrose, while providing less than about 5 calories. In another embodiment, tabletop sweetener compositions of the invention contain a plurality of sweetener particles, wherein such particles contain one or more of the ingredients present in the tabletop sweetener composition. In some embodiments, the tabletop sweetener composition substantially comprises sweetener particles. In such embodiments, the tabletop sweetener composition contains at least about 80 % by weight sweetener particles, or at least about 85 % by weight sweetener particles, or at least about 90 % by weight sweetener particles, based on the total weight of the tabletop sweetener composition.

Sweetener particles, when present in the tabletop sweetener composition, can have any size suitable for use of the composition as a sweetener. In some embodiments, the average size of the sweetener particles is between about 50 microns and about 1250 microns, e.g., between about 100 microns and about 1000 microns. Screening to eliminate particles of undesired sizes can be carried out during the manufacturing process. Thus, in some embodiments, the particle sizes, after screening to eliminate undesired large particles which may be as large as 1500 μπι, may vary up to about 16 mesh, e.g., up to about 14 mesh, or up to about 12 mesh, based on the standard United States sieve scale. Further, smaller particle sizes, e.g., about 50 mesh, 100 mesh, or 150 mesh, or particles having sizes less than about 1 μπι, e.g., less than about 0.5 μηι, may be present with the larger particles. Screening to eliminate particles having sizes less than, for example, about 100 mesh or 150 mesh can be carried out if desired.

Sweetener particles in the tabletop sweetener composition may or may not have uniform composition. Preferably, the tabletop sweetener compositions of the invention comprise nobiletin or a derivative or a hydrate thereof and an effective amount of cellulose where the composition is a mixture of particles. More specifically, the mixture comprises (a) particles having an erythritol core and (b) particles having a disaccharide core and nobiletin or a derivative or a hydrate thereof and the cellulose, as well as other components, are predominantly coated on the particles. These coatings on the cores can be either a continuous phase or a discontinuous phase, i.e., where the different coating components form discrete regions in the core coatings.

Thus, in another aspect, the invention relates to a tabletop sweetener composition comprising:

(a) a plurality of first sweetener particles, wherein the first sweetener particles have (i) a sugar alcohol core, in particular an erythritol core, (ii) a first sugar alcohol core- coating layer, in particular a first erythritol core-coating layer comprising nobiletin or a derivative or a hydrate thereof and cellulose, and (iii) a second sugar alcohol core- coating layer, in particular a second erythritol core-coating layer comprising a sugar sweetener, in particular a disaccharide, wherein the second sugar alcohol core-coating layer, in particular the second erythritol core-coating layer lies outside of the first sugar alcohol core-coating layer, in particular outside of the first erythritol core- coating layer; and

(b) a plurality of second sweetener particles, wherein the second sweetener particle has (i) a sugar sweetener core, in particular a disaccharide core, (ii) a first sugar sweetener core-coating layer, in particular a first disaccharide core-coating layer comprising nobiletin or a derivative or a hydrate thereof and cellulose, and (iii) a second sugar sweetener core-coating layer, in particular a second disaccharide core-coating layer comprising a sugar sweetener, in particular a disaccharide, wherein the second sugar sweetener core-coating layer, in particular the second disaccharide core-coating layer lies outside of the first sugar sweetener core-coating layer, in particular outside of the first disaccharide core-coating layer.

In such embodiments, the core-coating layers may or may not have uniform compositions, and may or may not substantially coat the underlying core or layer. In some embodiments, the first sugar alcohol core-coating layer, in particular the first erythritol core-coating layer and/or the first sugar sweetener core-coating layer, in particular the first disaccharide core- coating layer have discrete regions of nobiletin or a derivative or a hydrate thereof or a derivative or a stereoisomer or a salt or a hydrate thereof and cellulose. In another embodiment, the tabletop sweetener composition comprises a mixture of the plurality of first sweetener particles and the plurality of second sweetener particles.

In another embodiment of the tabletop sweetener composition, the sugar sweetener core, in particular the disaccharide core contains isomaltulose. Further, in some embodiments, the second sugar alcohol core-coating layer, in particular the second erythritol core-coating layer and/or the second sugar sweetener core-coating layer, in particular the second disaccharide core-coating layer contain isomaltulose.

These tabletop sweetener compositions may also contain flavorings (e.g., vanilla flavor), mouthfeel enhancers, and/or sweetness modifiers. When one or more of these are present, the first sugar alcohol core-coating layer, in particular the first erythritol core-coating layer and/or the sugar sweetener core-coating layer, in particular the disaccharide core-coating layer may contain one or more of flavorings (e.g., vanilla flavor), mouthfeel enhancers, and/or sweetness modifiers. Moreover, as used herein, the term "layer" may or may not refer to a material that entirely surrounds the underlying material. Thus, a "layer" may be non-uniform in composition and may provide only discontinuous coverage of the underlying material. Moreover, when one layer covers another, the boundary between the layers may or may not be discrete; thus, the boundary between layers may be continuous or semi-continuous.

In the sweetener compositions described herein, the tabletop sweetener compositions may or may not contain other particles in addition to the plurality of first sweetener particles and the plurality of second sweetener particles. The first sweetener particles and the second sweetener particles may have any particle size that is suitable for use of the composition as a sweetener. In some embodiments, the average size of the first sweetener particles and second sweetener particles is between about 50 microns and about 1250 microns, e.g., between about 100 microns and about 1000 microns. In some embodiments, the particle sizes of the first sweetener particles and the second sweetener particles, after screening to eliminate undesired large particles which may be as large as 1500 μπι, will vary up to about 16 mesh, e.g., up to about 14 mesh, or up to about 12 mesh, based on the standard United States sieve scale. Further, smaller particle sizes, e.g., about 50 mesh, 100 mesh, or 150 mesh, or particles having sizes less than about 1 μηι, e.g., less than about 0.5 μπι, will be present with the larger particles. In some embodiments, the tabletop sweetener composition comprises a mixture of the plurality of first sweetener particles and the second sweetener particles. Such a mixture may or may not contain other types of particles.

The layers in the sweetener composition particles are generally not distinct, i.e., there is no clear demarcation between the first layer and the second layer. For example, in one embodiment, the first layer contains nobiletin or a derivative or a hydrate thereof, optional flavoring components, etc., all encased in sugar sweetener, in particular encased in disaccharide; and the second layer will be predominantly sugar sweetener, in particular disaccharide with some of the other components. The relative quantities of the various components in the layers, and whether there are layers in the particles, can be modified as necessary by adjusting when during the manufacturing process the components are added.

In some embodiments of the invention, the tabletop sweetener composition comprises nobiletin or a derivative or a hydrate thereof and a taste-improving amount of cellulose as a mixture, where the mixture comprises (a) particles having a sugar alcohol core, in particular an erythritol core and (b) particles having a sugar sweetener core, in particular a disaccharide core. In some such embodiments, the disaccharide core comprises isomaltulose. Further, in some such embodiments, the sugar alcohol core, in particular the erythritol core and/or the sugar sweetener core, in particular the disaccharide core further comprise coating layers having discrete regions of nobiletin or a derivative or a hydrate thereof and cellulose. When such coating layers are present, the coating layers may or may not substantially coat the underlying core material. These particles may have any particle size that is suitable for use of the composition as a sweetener. In some embodiments, the average size of the particles is between about 50 microns and about 1250 microns, e.g., between about 100 microns and about 1000 microns. In some embodiments, the particle sizes of the particles range from about 16 mesh, or from about 14 mesh, or from about 12 mesh to about 100 mesh, based on the standard United States sieve scale.

Sweetener compositions of the invention may have any dissolution rate in water that is suitable for their use as sweeteners. In some embodiments, the sweetener composition can have a dissolution rate in water at 10°C of between about 100 seconds and about 200 seconds, e.g., between about 125 seconds and about 175 seconds, or between about 140 seconds and 160 seconds, based on the dissolution of about 2 grams of the sweetener composition in 240 ml of water. In some embodiments, the sweetener composition can have a dissolution rate in water at 45°C of between about 50 seconds and about 150 seconds, e.g., between about 75 seconds and about 125 seconds, or between about 85 seconds and 110 seconds, based on the dissolution of about 2 grams of the sweetener composition in 240 ml of water. In some embodiments, the dissolution rate of the sweetener composition is about 150 seconds at 10°C and about 96 seconds at 45°C, based on the dissolution of about 2 grams of the sweetener composition in 240 mL of stirred water.

In another embodiment, the invention relates to single-serving packets. In another embodiment, the invention relates to tabletop sweeteners comprising nobiletin or a derivative or a hydrate thereof. Preferably, the tabletop sweetener is a tabletop tablet sweetener, a tabletop "spoon to spoon" sweetener, a tabletop "sachet" sweetener, a tabletop liquid sweetener. The tabletop sweeteners, in addition to the nobiletin or a derivative or a hydrate thereof nobiletin or a derivative or a hydrate thereof component, may contain further substances including but not limited to aspartame, acesulfame potassium, binding agents, citric acid, cyclamate, lactose, carboxymethylcellulose, leucin, maltodextrin, isomalt, NHDC, potassium hydroxide (in aqueous solution), dextrose, other bulking agents, sucralose, sodium cyclamate, sodium hydrogen carbonate, sodium saccharin and tartaric acid.

In another embodiment, the invention relates to a package containing a predetermined amount, e.g., from about 0.8 grams to about 3.5 grams, of a solid tabletop sweetener composition, where the predetermined amount of the solid tabletop sweetener composition has a sweetness equivalent to about four times (by weight) the predetermined amount of sucrose, and where the solid sweetener composition comprises:

Example 1: In vitro identification of nobiletin as a sweet taste modulating substance - Detection of sweetness enhancer activity of nobiletin in a recombinant human taste receptor T1R2/T1R3 dependent cell based assay

Nobiletin has been identified in the screening phase as a sweet taste modulating substance by cell based assay analysis, acting as a sweetener and a fructose enhancer in vitro. 1.1 Description of the general method

In wild type taste cells, e.g. in human taste buds, signal transduction is accomplished by the G-proteins gustducin and/or by G-Proteins of the G alpha-i type. Encountering sweet ligands, the heterodimeric human taste receptor T1R2/T1R3 reacts with induction of second messenger molecules, namely either the increase of the cAMP level in response to most sugars or the increase of the calcium level in response to most artificial sweeteners (Margolskee, 2002; J. Biol Chem. 277, 1-4, which is incorporated by reference in its entirety). To analyze the function and activity of a test compound, e.g. of nobiletin, the heterodimeric hTlR2/hTlR3 sweet taste receptor is utilized in a calcium dependent cell based assay. TIR type taste receptors are transfected with the multicistronic plasmid vector pTrix-Eb-R2R3 in a HEK293 cell line stably expressing the promiscuous mouse G-alpha- 15 G-protein.

For the generation of stable cell lines a multicistronic expression unit using human taste receptor sequences is used. In a tricistronic expression unit of the expression vector pTrix- Eb-R2R3 is under the control of the human elongation factor 1 alpha promoter. Using standard cloning techniques the cDNA for the receptors htlR2 and htlR3 and the cDNA for the blasticidin S deaminase gene is cloned. To enable the translation initiation of each gene of this tricistronic unit two EMC-virus derived internal ribosomal entry sites (IRES - also termed Cap-independent translation enhancer (CITE)) are inserted (Jacksonet al, Trends Biochem Sci (1990) 15, 477-83; Janget al., J Virol (1988) 62, 2636-43, which are incorporated by reference in their entirety).

The tricistronic expression unit is terminated by a simian virus 40 polyadenylation signal sequence. This composition permits the simultaneous expression of all three genes under the control of only one promoter. In contrast to monocistronic transcription units, which integrate independently from each other into different chromosomal locations during the process of stable cell line development, the tricistronic transcription unit integrates all containing genes in one and the same chromosomal locus. Due to the alignment of the genes, the blasticidin S deaminase gene is only transcribed in case a full length transcription takes place. Moreover the polarity of multicistronic transcription units (Moser, S.et al, Biotechnol Prog (2000) 16, 724-35, which is incorporated by reference in its entirety) leads probably to a balanced stoichiometry of the receptor genes and their expression rates in the range of 1 :0.7 up to 1 :1 for the first two positions whereas the blasticidin S deaminase gene compared to the receptor genes in the third position is expressed to a lesser extend.

Assuming that for the functional heterodimeric receptor htlR2/htlR3 a 1 :1 stoichiometry is needed the lesser polarity effects for the receptor genes promote the desired stoichiometry whereas the reduced expression of the deaminase promotes an integration locus with enhanced transcriptional activity. Generation of stable hTlR2/hTlR3 expressing cells are performed by culturing the transfected cells in the presence of blasticidine.

For measurement of human T1R2/T1R3 taste receptor dependent activity a control cell line without sweet receptor based on HEK 293 and a cell line expressing the sweet receptor hTlR2/hTlR3 based on HEK 293, respectively, are seeded into assay plates and labelled with the calcium sensitive fluorescence dye Fluo4-AM in a culture medium. The potential modulators, e.g. the test compound, are added to the control cell line and to the cell line expressing the sweet receptor hTlR2/hTlR3, respectively.

Response to different concentrations of the modulator in the presence of fructose is recorded as Fluo4-AM fluorescence increase initiated through the hTlR2/hTlR3 dependent increase of the second messenger calcium. The applied fructose concentration is chosen from the results of preexaminations showing that fructose, in these concentrations, is barely activating the sweet taste receptors within this cell based assay. Thus a sweetness enhancing property of a test compound is detectable in the presence of the sweetener fructose.

1.2 Preparation of the cell lines and cell culture

A stable cell line based on HEK293 was termed HEKal5#17 served as control for functional Ga-protein and a stable cell line HEKGal5#17R2R3b#8 C6 served as cell line expressing the sweet receptor hTlR2/hTlR3 based on HEKGal5#17. The cells were cultured in DMEM/HG and 10% FCS Gold, 4mM L-Glutamin, l,3mg/ml Geneticin (HEKGal5#17) or the same medium additionally containing 6μg/ml Blasticidin (HEKGal5#17R2R3b#8 C6). The medium for the assay was DMEM/HG (high glucose, 4.5 g/1 glucose, Life Technologies) and 10% FCS Gold, 4mM L-Glutamin (HEKGal5#17) or DMEM/LG (low glucose, 1 g/1 glucose; Life Technologies) and 10% FCS Gold (HEKGal 5#17R2R3b#8C6), respectively.

1.3 Evaluation of the sweet receptor modulating activity of nobiletin

In order to evaluate the sweet receptor modulating activity of nobiletin, nobiletin was added to the cultures in a volume of 50μ1 and a concentration of 25 μΜ in the secondary screening or 30 μΜ in the tertiary screening, respectively. Controls were KH -buffer (Krebs HEPES-buffer: 118mM NaCl, 4.7mM KC1, 1.2mM MgS0₄, 1.2mM KH₂P0₄, 4.2mM NaHC0₃, 1.3mM CaCl₂, lOmM Hepes, pH 7.4) either without or with sweetness enhancer. As natural and artificial sweeteners either fructose (20mM), acesulfam K (30mM) or sodium cyclamate (30 mM) were used.

Further controls for function of G-protein and receptor were isoproterenol (ΙμΜ, Sigma Aldrich), ionomycin (1 μΜ, Calbiochem) and ATP (1 μΜ, Applichem).

DMSO was diluted in KH -buffer/fructose (lOOmM stock solution = 50μΜ final test concentration = 1 :400 dilution). 1.4 In vitro cell based assay procedure

For measurement of human T1R2/T1R3 taste receptor dependent activity, on day 1 of the test procedure the HEKal5#17 cells (control cell line without sweet receptor) and the HEKGal 5#17R2R3b#8 C6 cells (cell line expressing the sweet receptor hTlR2/hTlR3), respectively, were transferred to low-glucose medium.

On day 2 the cells were seeded into assay plates at a density of 25,000 cells/well. Assay plates for fluorescence measurement (black clear bottom 96-cavity plates, Greiner Bio- One) were coated with poly-D-lysine. For direct comparison both cell lines (control cell line without sweet receptor and cell line expressing the sweet receptor hTlR2/hTlR3) were seeded into different cavities of the same assay plate. The plate was placed into the incubator for 48 hours at 37°C, 5% C0₂, 100% relative humidity. On day 4 the calcium assay was performed. For this assay, the cells were marked with Fluo4-AM in medium and KH-buffer. To each cavity ΙΟΟμΙ KH-Puffer/25(^M sulfinpyrazoneA^M Fluo4-AM were added gently to ΙΟΟμΙ medium (final concentration of Fluo4-AM = 2μΜ, stock solution of Fluo4-AM ImM in DMSO, excitation at 485 nm, emission at 520 nm, Fisher Scientific, 58239 Schwerte, Germany).

The plate was placed into the incubator for 1 hour. In the mean time the test substances ("ligands") were prepared in a separate plate (5 times concentrated, 150 μΐ/cavity, and then automatically

were transferred into the screening cell plate by pipetting robot (FLEX-station, Molecular Devices, Sunnyvale, California).

The culture medium was carefully removed and 200μ1

sulfinpyrazone per cavity was added slowly. Cells were left in the FLEX-station for 20 minutes for adaptation, followed by measurement at 37°C.

1.5 Results of the in vitro cell based assay

The results of this assay are shown in the bar diagram of Figure 1. In the bar diagram the grey bars (w/o hTlR2/hTlR3, control) indicate the measured Fluo4-AM fluorescence increase of the respective test compound added to the control cell line, the black bars (+ hTlR2/hTlR3, assay) indicate the measured Fluo4-AM fluorescence increase of the respective test compound added to the cell line expressing the sweet receptor hTlR2/hTlR3. The first bar (sodium cyclamate) shows that the control sweetener sodium cyclamate does not activate the control cell line, but activates the cell line expressing the sweet receptor hTlR2/hTlR3. Consequently, this bar shows that sodium cyclamate is a sweetener.

The second, third and fourth bars (isoproterenol, ATP and ionomycin) show that the respective control compounds activate both the control and the cell line expressing the sweet receptor hTlR2/hTlR3 and confirm the function of the G-protein and receptor.

The fifth bar (KH buffer/fructose) shows that fructose does neither activate the control cell line, nor the cell line expressing the sweet receptor hTlR2/hTlR3.

The seventh bar (secondary screening) shows that nobiletin in the presence of fructose does not activate the control cell line but activates the cell line expressing the sweet receptor hTlR2/hTlR3. Consequently, nobiletin is a sweetener and/or a fructose enhancer. The eighth bar (nobiletin without fructose) shows that nobiletin does not activate the control cell line, whereas the cell line expressing the sweet receptor hTlR2/hTlR3 is activated. Consequently, nobiletin is a sweetener.

The ninth bar (nobiletin in the presence of fructose) shows that nobiletin does not activate the control cell line, but activates the cell line expressing the sweet receptor hTlR2/hTlR3 and enhances the activity of fructose (cf. also the fifth bar). Figure 2 shows that the selective stimulation of receptor carrying cells by nobiletin is verified by measuring the time response in the cell assay over a period of 57 seconds.

Consequently, the assay shows that nobiletin is a mixed sweetener and fructose enhancer. Example 2: Taste and spit assay with nobiletin

The taste of a sample of nobiletin with regard to sweetness and fructose enhancing features was assessed by using a panel of trained sensory evaluators experienced in the sweet taste estimation procedure. 5 individuals were asked to taste the quality of single samples of 10 ml volume.

2.1 General procedure

Panelists were asked to take a sample of the liquid to be assessed (25 μΜ test substance nobiletin in 0.5 % ethanol) into the mouth and after some time allowed for taste perception to spit the sample out completely. Subsequently, the panelists were asked to rinse their mouth well with water or black tea to reduce any potential carry over effects. The tasting of a sample could be repeated if required. 2.2 Taste and spit phase I - Qualitative Assessment

In a first descriptive test 6 individuals were asked to taste the quality of single samples of 10 ml volume (maximum 3 subsequent samples). The samples were served at ambient temperature. The individuals of the taste panel were asked to answer the following questions with regard to the quality of taste: 1) does the sample taste sweet?, 2) is there another taste detectable (bitter, sour, salty, umami)?, 3) is there an off- or aftertaste?, 4) is there anything else remarkable about the perception of the sample? Results: No characteristic taste was identified in the sample containing nobiletin at the indicated concentration. Importantly, no off-taste was detected by the taste panel. These results show that nobiletin, beneficially, may be utilized as a sweetener and/or a sweetness enhancer without contributing off-tastes to the resultant product.

2.3 Taste and spit phase II - Assessment of fructose enhancing features

In the next step the panelists were asked to answer questions in a pairwise comparison test to determine the enhancement of sweet taste of the test substance with fructose relative to fructose only. Again, 5 individuals were given samples of 10 ml volume. This time two samples were prepared for direct comparison regarding sweetness. One sample contained fructose (4%) in solvent (0.5 % ethanol) and the other sample additionally contained 25 μΜ of the test substance nobiletin. Designation of the samples with A and B was randomized and decoded after the taste procedure. The questions to be answered were: 1) does one sample taste sweeter than the other?, 2) if so, which one?, 3) are there any other differences in the taste between the two samples?

Results: The results of the taste and spit assay are based on a qualitative evaluation of the differences between the two samples (cf. Fig. 3).

Four panelists identified the sample containing 4 % fructose with nobiletin as sweeter than the sample containing 4 % fructose only. Two panelists identified the sample containing 4 % fructose only as sweeter than the sample containing 4 % fructose with nobiletin. Consequently, at the indicated concentration, nobiletin is perceived as a fructose enhancer.
