A large number of researches show that the tea polyphenol has an antioxidant effect, and the tea polyphenol and vitamin C have antioxidant synergistic effect. GB 2760 national food safety standard food additive use standard has listed tea polyphenol as a food antioxidant directory, and is widely applied to grease, fried flour products, instant rice flour products, cakes (the maximum use amount is 0.4g/kg calculated by catechin in the grease), grease-containing stuffing, meat products, aquatic products, vegetable protein beverages and puffed foods.
The anthocyanin is widely present in plants, belongs to a class of water-soluble pigments, belongs to flavonoid compounds, contains an aromatic ring structure and active hydroxyl, can remove oxygen free radicals, and has an antioxidant effect. Researches show that the natural extract rich in anthocyanin is an ideal antioxidant and can be applied to the fields of food, daily chemicals and the like.
Anthocyanidin in natural plants can change color with different pH values of cell sap, and is reddish when the cell sap is acidic and bluish when the cell sap is alkaline, and most of colorful colors of fruits, vegetables, grains, flowers and the like are related to anthocyanidin.
Currently, researches on anthocyanins mainly focus on separation and extraction, stability research, biosynthesis technology research and the like. The application research of anthocyanin in the food field mainly focuses on: (1) the natural material rich in anthocyanin is applied to the formula of food processing and the technical research of the preparation process; (2) research on antioxidant technology of anthocyanin in food, and the like; however, no report is found on the research of applying the color reaction of the anthocyanin to the instant pastry.
Most of pigments used in the food industry are synthetic pigments, almost all have toxicity of different degrees, and are harmful to the health of human bodies after long-term consumption; in addition, a certain amount of synthetic antioxidant is generally added in the processing process of the food, and the long-term eating of the food also can affect the human health.
Patent document CN 111700297a discloses a multicolor gradient cake making process and a multicolor gradient cake, which adopts the made cake crust with different colors to form a gradient color cake crust by pressing and splicing, and overcomes the technical problem of single color of the existing cake crust. According to the invention, by utilizing the antioxidation effect of tea polyphenol in cooperation with anthocyanin and utilizing the color reaction specificity of anthocyanin under different pH values, natural raw and auxiliary materials such as fruits, vegetables, grains and flowers rich in anthocyanin are applied to cake products, meanwhile, the edible acid-base agent is created independently, and the acid-base agent is coated, drawn or sprayed on the cake before the cake is eaten, so that the anthocyanin in the cake can be in different colors due to the change of the pH value, the color vision of the cake is improved, and the pleasure of eating the cake is increased. Meanwhile, the tea polyphenol and the anthocyanin in the cake can reduce the use of artificially synthesized antioxidants, the anthocyanin can reduce the use of artificially synthesized pigments, the cake is endowed with new functions and health attributes, the dual pursuits of people on the safety, health and nutritional quality of the cake are met, and meanwhile, the high-quality life experience feeling of people for enjoying the cake can be improved. At present, no instant color-changing pastry rich in anthocyanin exists in the market, and the product can enrich the variety of pastry products, improve the product quality and has stronger market competitiveness.
