Carotenoids (Carotenoids) are one of the important pigments of plants, which impart vivid colors to flowers and fruits, and are commonly found in yellow, orange-red or red pigments of animals, higher plants, fungi, algae. Carotenoids are also closely related to human health and are one of the indispensable nutritional components in food. It is an isoprenoid polymer containing 40 carbons, i.e., a tetraterpene compound. Typical carotenoids are formed by 8 isoprene units joined end to end. The color of carotenoids varies depending on the number of conjugated double bonds. The greater the number of conjugated double bonds, the more red the color shifts. The natural carotenoids found so far have more than 700, but according to the food safety national standard food additive use standard GB2760-2014, only three carotenoids are used in the beverage at present, and can be divided into two types according to the difference of chemical structures, wherein one type is carotene (only containing two elements of hydrogen and no oxygen element, such as beta-carotene and lycopene), and the other type is lutein (containing oxygen functional groups such as hydroxyl, ketone, carboxyl, methoxyl and the like).
The fruit juice beverage market is a huge market, in order to keep fresh visual perception of fruit juice beverages, the most common food additive is pigment, which is classified into artificial pigment and natural pigment, wherein the artificial pigment gradually fades out of the fruit juice beverage world along with the increase of health consciousness of consumers in recent years, the most common and healthy use method at present is to add natural pigment such as carotenoid into the fruit juice beverage, but the fruit juice beverage added with carotenoid is easy to generate oxidation reaction under the comprehensive actions of illumination, metal ions, oxygen and the like in the quality guarantee period of months, so that the quality problems of darkening and fading of the color and luster of products are caused, and manufacturers producing the fruit juice beverages with long quality guarantee period are troubled all the time.
The patent number CN201910951746.3, the patent name "a color protection method of carrot juice", the invention discloses a color protection method of carrot juice. The method comprises the following steps: selecting carrots without pathological changes and mildewing, cleaning and slicing the carrots, putting the carrots into hot water with the temperature of 80-100 ℃ for blanching treatment for 0-120s, and putting the carrots subjected to blanching treatment into 100 parts by weight of the carrots, wherein the carrots comprise: 0.1 to 1 portion of citric acid, 0.1 to 1 portion of ascorbic acid or 0.1 to 1 portion of D-sodium erythorbate, and the balance of water in a color fixative, and then the carrot slices are fished out, cleaned and squeezed into juice. Compared with the prior art, the invention has the advantages that the color protection method is simple and easy to operate, the carrots are easy to process, various chemical reagents are not required to be added, the color protection process cost is reduced, and the color protection can be effectively carried out. The carrot juice color-protected by the color protection method can effectively protect the color of the carrot juice, can protect the color for a long time, has less color browning, and can effectively ensure the quality of carrot juice products.
The method has the defects that vitamin C is mostly adopted in the color protection method of the prior fruit juice beverage (containing fruit juice, vegetable juice and fruit juice carbonated beverage) added with carotenoid, the color stability of the fruit juice beverage for one or two months can only be ensured under the illumination, and the quality problems of darkening, fading and the like of the color of the fruit juice beverage under the illumination condition in the long shelf life of 12 months cannot be solved.

The components of the composite color fixative are safe and nontoxic, and the edible safety is high. The color protection mechanism is as follows: because the molecular formula of the carotenoid contains more conjugated double bonds, the carotenoid is easy to generate oxidation reaction under the comprehensive effects of illumination, metal ions, oxygen and the like, so that the quality problems of darkening in color and luster, fading and the like are caused, the conventional color fixative can only protect the color from certain single angles generally, and the effect is weak. The composite color fixative is researched from the fading mechanism of carotenoid, and is effectively strengthened on the basis of taking vitamin C which is commonly used at present as an antioxidant. Firstly, the application of the EDTA disodium is from the perspective of chelating metal ions such as iron, copper, calcium, magnesium and the like, so that the conjugated double bonds of the carotenoid are prevented from being damaged to generate color fading, and the antioxidant capacity of the vitamin C is protected and enhanced; secondly, the hexametaphosphate is used as an ascorbic acid decomposition inhibitor for the fruit juice beverage, can further chelate calcium ions and other metal ions in the fruit juice beverage, and plays a role in preventing the carotenoid from fading due to the change of molecular formula; meanwhile, the spearmint extract is used as a natural antioxidant, can effectively remove free radicals and active oxygen generated after the beverage is irradiated by light, and blocks the free radicals and the active oxygen from destroying conjugated double bonds of the carotenoid to generate a fading phenomenon. The compound color fixative can protect the carotenoid from changing molecular formula from multiple angles, and the four components supplement each other to play a role in synergy, thereby ensuring the stability of the carotenoid in shelf life.

for the above examples and comparative examples, the color protection effect of the natural pigment is evaluated by a general color stability evaluation method of the natural pigment in the industry, and the specific method is as follows:
the Lab color model is composed of three elements of illumination and related colors, namely a and b. L represents illuminance, corresponding to brightness, a represents a range from magenta to green, and b represents a range from yellow to blue.
2. Detecting the Lab value by adopting a colorimetric detection instrument, and using the formula:
Figure BDA0002793295360000111
and calculating the total color difference of the pigments to evaluate the color protection effect of the composite color fixative in a system with the added carotenoid juice.
Table 1 evaluation of color-protecting effect by composite color-protecting agent for each item
Figure BDA0002793295360000112
And (4) conclusion: as can be seen from examples 1 to 5, the color fixative compound has a remarkable color fixative effect, and the synergistic effect of the components well protects the stability of the conjugated double bond in the carotenoid molecular formula and prevents the carotenoid molecular formula from being damaged by the presence of light, metal ions, free radicals and the like, so that the color fading phenomenon is generated.
The comparative example 1 is different from the example 1 in that the four components of the composite color fixative are not in the ratio range, thereby failing to exert the optimal color fixative effect, and the analysis reason is probably that the vitamin C cannot exert the antioxidant effect well due to the failure of the composite color fixative in the amount to completely chelate metal ions, and simultaneously, the capability of the spearmint extract for scavenging free radicals and active oxygen is also influenced, thereby weakening the whole color fixative effect.
The difference between the comparative example 2 and the example 1 is that the composite color fixative is added with another component, namely sodium tripolyphosphate, and is changed into five color fixatives to be compounded, the effect of the composite color fixative of the formula is weakened relative to the example 7, because the sodium tripolyphosphate and the sodium hexametaphosphate can chelate calcium ions and other metal ions in the fruit juice beverage, so that the carotenoid is prevented from changing the molecular formula and fading, but simultaneously, competitive inhibition can be generated, the chelating capacity is reduced, and the effect of the whole composite color fixative is influenced.
Comparative example 3 is different from example 1 in that the color-protected object is changed from carotenoid to lemon yellow, and the color-protecting effect is not satisfactory because lemon yellow is an azo-type acidic pigment against Cu2+Ion labile, Cu2+The ions enable the lemon yellow solution to obviously fade, and although EDTA-2Na with a good metal ion chelating effect is used as a color fixative to play a certain color protection effect, the lemon yellow can accelerate reaction to generate a fading phenomenon after meeting light in the presence of a reducing agent VC, so that the color protection effect of the composite color fixative on the lemon yellow is not ideal.
Comparative example 4 differs from example 1 in that no complex color fixative was added to the beverage; in the absence of a color fixative, the chromophoric group is easily oxidized, reduced and complexed, so that the structure and the property of the group are changed, the energy required for electron transition is changed, the wavelength of absorbed light is also changed, and the color is changed or faded.
Comparative example 5 is different from example 1 in that the component of the composite color fixative is only vitamin C.
Comparative example 6 is different from example 1 in that the composite color fixative has only vitamin C and EDTA-2 Na.
Comparative example 7 is different from example 1 in that the complex color fixative has only vitamin C, EDTA-2Na and sodium hexametaphosphate.
It can be seen from comparative examples 5 to 7 that the elimination of the components of the composite color fixative reduced the color fixative effect of the composite color fixative, and the composite color fixative within the range of the components of the present invention was required to have superior color fixative effect.
Fig. 1 illustrates an ingredient process of fruit and vegetable juice beverages and fruit juice carbonated beverages containing the composite color fixative, which is designed according to process parameters and ingredient sequences required by actual production, so that the composite color fixative can effectively play a role in a system.
Fig. 2 is a graph of observation results of fruit and vegetable juice and fruit juice carbonated beverage of different color protection schemes placed under light for 2 months. As can be seen from the figure and the data, the colors of the five examples are stable after illumination, while comparative example 4 without the composite color fixative in the comparative example are greatly changed, and the fading phenomena are generated to different degrees when the quantity of the color fixative is reduced or increased and the dosage of the composite color fixative is not in a proportional range, while the composite color fixative hardly plays a role after the color fixative is changed into lemon yellow, so that the composite color fixative in the patent has obvious specific color fixative effect on fruit and vegetable juice beverages containing carotenoid and fruit juice carbonated beverages.
It is clear from the data of examples 1 to 5 and comparative examples 1 to 7 that the above requirements can be satisfied in all aspects only by the embodiments within the scope of the claims of the present invention, and an optimized embodiment can be obtained, and an optimum compound color fixative for carotenoid-containing fruit juice beverages and a color fixative method thereof can be obtained. The change of the mixture ratio, the replacement/addition/subtraction of raw materials or the change of the feeding sequence can bring corresponding negative effects.
The raw materials and equipment used in the invention are common raw materials and equipment in the field if not specified; the methods used in the present invention are conventional in the art unless otherwise specified.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
