Definitions
- the present invention relates to a process for producing swelling starch and the swelling starch obtainable by this process. It also relates to compositions containing this swelling starch, in particular dry mixes for the production of instant puddings. The present invention furthermore relates to the use of the new swelling starches for the production of foods, in particular instant puddings, animal feed, adhesives and paints.
- Swelling starches are physically modified starches, which are mainly produced by wet thermal digestion. In contrast to native starch, they form dispersions or pastes or gels with cold water, depending on the concentration of the swelling starch used and on the type of starch used to produce the swelling starch. Because of these properties, there are a number of possible uses for source starches in the food industry and also in many technical areas.
- the use of swelling starch, which is also called cold-swelling starch, instead of native starch has the advantage in various cases that production processes can be simplified and shortened. Basically, the production of cold swelling starch (swelling starch) with different
- Industrial source starch is mainly produced using the drum dryer.
- a precooked starch paste is placed on the roller for drying.
- drum drying process in which the pre-gelatinization is carried out in the presence of additives such as salts, acids, lipids etc. and / or in which chemically modified starches are used as the starting material.
- additives such as salts, acids, lipids etc. and / or in which chemically modified starches are used as the starting material.
- swelling starches are required which, after being stirred into cold liquids, such as water or milk, form cut-resistant gels within a short time, for example in the case of cooking puddings.
- cold liquids such as water or milk
- the commercial swelling starches from wheat, potato or corn starch do not meet these requirements.
- additions to the swelling starch such as gelatin, alginate, carrageenan (carrageenan) and / or inorganic salts, are necessary in the swelling starches which have been commercially available to date.
- the present invention is therefore based on the object of providing swelling starches which, after being stirred into a cold liquid at a certain concentration, form cut-resistant gels after a short swelling time.
- potato starches In contrast to cereal starches, potato starches contain glucose units with phosphate ester groups, which give them specific functional properties.
- the phosphate content of cereal starch results from the content of phospholipids, which do not occur in potato starch.
- the majority of the phosphate ester groups of potato starch are bound to the amylopectin molecules, mainly to the C 6 atom of the glucose units, the rest predominantly in C 3 -, least in the C 2 position (Schierbaum, F .: starch 21 (1969 ) 87; Hizukiri, S. et al. Strength 22 (1970) 338).
- the phosphate ester group content affects above all the gelatinization behavior of the starch, the gelatinization temperature decreases, the peak viscosity increases, and it also reduces the tendency towards retrogradation of the boilings or pastes and improves their freeze-thaw stability.
- the total phosphate content of conventional potato starch is generally in the range of 10-30 ⁇ mol phosphate / g starch, and comes from the monophosphate ester groups, since the lipid content of potato starch is negligible.
- genetically modified potatoes can be used to obtain potato starches with total phosphate contents up to the order of 120 ⁇ mol phosphate / g starch.
- the natural amylose content of conventional potato starches is generally in the order of 20-25% by weight.
- the native starch In order to achieve higher amylose contents, the native starch must be subjected to enzymatic debranching, with short-chain amylose molecules being formed by debranching amylopectin molecules.
- genetically modified potatoes can be used to obtain potato starches with a natural (long-chain) amylose content of more than 30% by weight and of the order of more than 70% by weight.
- Other starches, such as wheat or corn starch have a higher content of natural amylose, but on the other hand only a very low (wheat starch) or negligible (corn starch) content of phosphate ester groups.
- the invention therefore teaches to use potato starch which has a high content of phosphate ester groups, but a potato starch with an increased amylose content in comparison to potato starch from wild type plants.
- the potato starch contains no lipids, which form complexes with amylose and would thus hinder the gel and / or paste formation of the swelling starch.
- spray drying gives a product which contains a high proportion of undesirable soluble carbohydrates, so that roller drying is provided according to the invention.
- potato starches with an increased amylose content compared to potato starch from wild type plants are suitable for roller drying.
- US 3 607 394 discloses the production of swelling starch by heat treating an aqueous suspension of a starch containing at least 50% amylopectin and roller or spray drying.
- the swelling starch obtained in this way should form smooth pastes and have a minimal tendency to increase viscosity when standing.
- amylose-rich starches which in the case of US3607394 mean starches which contain 60% or more amylose, provide products which, when reconstituted with water, form gels which do not have the desired texture.
- Spray drying which leads to an undesirably high proportion of soluble carbohydrates, is also recommended.
- EP 480 433 A2 discloses foods containing soluble, amylose-rich starches selected from i) spray-dried non-granular starches, ii) spray-dried gelatinized starches and iii) enzymatically branched gelatinized starches containing at least 40% short-chain amylose. These foods are said to be characterized by the formation of strong gels. Corn starches and pea starches are the only types of starch that are mentioned, and special starch digestion (jet-cooking) is required. It is expressly mentioned that known amylose-rich starches require higher cooking temperatures for their digestion than other starches. Drum drying is said to be unsuitable, unless for starches with enzymatically branched, soluble amylose-rich starches.
- the present invention uses a potato starch with a high content of native long chain amylose.
- Short-chain amylose means one with a maximum chain length DP max ⁇ 100
- the present invention therefore relates to a process for producing a swelling starch with good gelling properties, in which a) a suspension of starch and water is produced, b) the suspension produced in a) is applied to a hot roller of a drum dryer; and c) the swelling starch obtained by process step b) is isolated, the process according to the invention being characterized in that a potato starch with an amylose content of at least 30% by weight is used.
- swelling starch is understood to mean a physically modified starch which, in contrast to native starch, forms dispersions, pastes or gels with cold water or cold milk depending on the concentration of the swelling starch used.
- hot roller should be understood to mean a roller of a roller dryer which has a temperature of at least 100 ° C., preferably between 120 ° C. and 200 ° C., in particular between 140 ° C. and 180 ° C. and particularly preferably between 150 ° C and 170 ° C.
- Roller dryers for producing swelling starch are known to the person skilled in the art and have been described, for example, in Starch: Chemistry and Technology, Vol. II, Academic Press, New York, San Francisco, London (1967) published by RL Whistler and EF Paschall.
- a steam-heated single-roll dryer with one or more application rollers can be used.
- other drum dryers such as. B. electrically heated single-drum dryer with roller diameters of approx. 160 mm is possible.
- the potato starches used in connection with the present invention have an amylose content of at least 30%, in particular 30% -85%, e.g. 30% -65% or 32% -55%, preferably 32% -45%.
- the amylose content is preferably determined via the colorimetric determination of the amylose content described by Hovenkamp-Hermelink (Potato Research 31, (1988), 241-246).
- the potato starch used in process step a) should have a total phosphate content of 5-120 ⁇ mol phosphate / g starch, preferably 10-120 ⁇ mol phosphate / g starch, 15-110 ⁇ mol phosphate / g starch and particularly preferably 60-110 ⁇ mol phosphate / g starch.
- total phosphate content of the starch means the content of phosphate covalently bound in the form of starch phosphate monoesters in the C2, C3 and C6 positions of the glucose units.
- Wild-type potato plants usually synthesize a starch with an amylose content of approximately 17% to 23% (determination of the amylose content according to Hovenkamp-Hermelink).
- the potato starches used in connection with the present invention with an amylose content of at least 30% can be isolated, for example, from transgenic potato plants.
- Transgenic potato plants which synthesize a starch with high amylose contents and high phosphate contents which are particularly suitable for the present invention are disclosed in the applicant's German patent application, filed on December 19, 2002.
- potato starches from other origins are also conceivable, provided that they have an amylose content of at least 30%.
- the international patent application WO 97/11188 describes transgenic potato plants which, owing to the antisense inhibition of the R1 gene and the BEI gene, synthesize a starch with an amylose content of approximately 30% to 70%, the amylose content using the Hovenkamp method. Hermelink (Potato Research 31, (1988), 241-246). The phosphate content of these potato starches is reduced compared to the phosphate content of starch from wild type plants.
- the potato starch used in the method according to the invention comes from potato plants which have a reduced gene expression of the R1 and BEI genes in comparison to corresponding wild type plants (see WO 97/11188).
- the potato starches used in connection with the present invention have the advantage that they are sufficient with the help of the drum dryer can be unlocked.

- the swelling starch was produced with the modified crepes maker by applying the starch suspension with the help of an application chute to the hot roller surface.
- the product film was removed with a knife, air-cooled, openly equilibrated overnight, then comminuted at 10,000 rpm with a mill (model ZM 100, sieve ring 0.2 mm) from Retsch GmbH & Co KG (Haan, Germany).
- the swelling starch was produced with a 12.5% strength starch suspension, which was applied to the 160-190 ° C hot roller.
- the starch was partially pre-gelatinized in the order shaft.
- the commercial product for the production of instant puddings included for comparison contained the following ingredients: sugar, modified starch, hardened vegetable fat, glucose syrup, emulsifier (esterified mono- and diglyceride), milk protein, thickening agent (carrageenan, alginate), table salt , Color (carotene, riboflavin), aroma.
- the preparation was carried out according to the manufacturer's instructions by stirring 12.0 g of the commercial product in 50 ml of milk.
- the thickening of the commercial product is based primarily on the gelation of alginate and carrageenan.
- the declared modified starch a swelling starch, is added as a filler or for "body formation".
- the addition of the aforementioned hydrocolloids is not required for gelation in the case of pudding with swelling starch from high-amylose potato starch varieties (HA).

- the gel strength of pudding samples produced in the same way (the production was carried out as described above for the pudding from HA swelling starch), which was produced from swelling starches of different origins, was measured with the texture analyzer after a standing time of different lengths. From the figure 1 it can first be seen from the increase in the gel strength of the pudding samples that the maximum gel strength was reached the faster the lower the viscosity of the preparation and that in the case of the stronger gels it increased up to two hours.
- the pudding which was made from swelling starch from HA potato starch, has a cut-resistant texture in contrast to the comparison puddings.
- the cut resistance of the texture can also be clarified indirectly by determining the shape stability of the puddings using the method described above. If you compare the shape stability of puddings that were made from different types of swelling starch, you can see that the puddings that were made from swelling starch of HA starch (see above for production) compared to puddings that were made in the same way (4.0 g swelling starch , 5.0g powdered sugar, 0.1g CaCI 2 in 50ml milk) from other source starch types (corn source starch, wheat source starch, potato source starch) have a significantly higher dimensional stability. The same applies in comparison to the pudding produced from the commercial product described above.
