Embodiment 1

[0033] In this example, blueberry pigment microcapsules were prepared according to the following steps:

[0034] (1) Preparation of wall material solution:

[0035] Add chitosan to deionized water under 30℃~40℃ water bath and stir until it is completely dissolved to obtain a chitosan solution with a mass concentration of 0.5%;

[0036] Add sodium tripolyphosphate and sodium alginate to deionized water, stir with a magnetic stirrer until the solution becomes transparent to obtain a sodium tripolyphosphate-sodium alginate mixed solution, wherein the mass concentration of sodium tripolyphosphate is 1%, The mass concentration of sodium alginate is 0.4%;

[0037] (2) Emulsification of core material:

[0038] According to the mass ratio of chitosan, Tween-80, and sucrose fatty acid ester SE-5 of 10:1:1, add Tween to the chitosan solution configured in step (1) under the water bath condition of 30℃~40℃ -80 and sucrose fatty acid ester SE-5, stir for 10 minutes, add blueberry pigment extract ...

Abstract

The invention relates to a blueberry pigment microcapsule and a preparation method thereof, and belongs to the technical field of food processing. A wall material of the microcapsule is composed of chitosan, sodium tripolyphosphate and sodium alginate, and a core material is water-soluble blueberry pigment. In the microcapsule, the core material is emulsified by high pressure homogenization, and then the microcapsule is formed by a complex coacervation method and then obtained by vacuum freeze-drying. The preparation process is simple, preparation conditions are mild, and the method is easy topopularize. The prepared microcapsule has good dispersibility and high stability and is suitable for being used in food, health care products, cosmetics and other industries.

Description

Technical field [0001] The invention relates to a blueberry pigment microcapsule and a preparation method thereof, and belongs to the technical field of food processing. Background technique [0002] The pigment in blueberry fruit belongs to 2-phenylbenzopyran (C 6 -C 3 -C 6 ) Is the nucleus of flavonoids. As natural antioxidants and free radical scavengers, it has many physiological activities such as anti-oxidation, promoting retin synthesis, improving immunity, anti-cardiovascular disease, anti-aging, etc. Food, cosmetics, medicine and other fields have broad application prospects. But blueberry pigment is a water-soluble pigment, it is a yellow salt cation, which is strong in basicity and oxidation. The phenolic hydroxyl group on its core is acidic and reducing, and the conjugated double bond on its pyran ring is prone to B-ring electron transfer. Therefore, environmental factors such as acids, alkalis, oxidants, and light radiation can interact with blueberry anthocyanins t...
