Title:
MICROENCAPSULATION METHOD FOR IMPROVING STABILITY OF ANTHOCYANIN, PRODUCT THEREFROM AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/211786
Kind Code:
A1
Abstract:
Disclosed are a microencapsulation method for improving the stability of anthocyanin, a product therefrom and the use thereof. The method for preparing an anthocyanin microcapsule comprises: (1) using sodium alginate as a wall material, and adding the sodium alginate and calcium carbonate to water to swell for 1-2 h so as to obtain a wall material gel system; (2) using the anthocyanin obtained with a special process as a core material, and mixing the wall material gel system and an anthocyanin solution thoroughly for use, so as to obtain an aqueous phase; (3) mixing Span 80 and a vegetable oil to obtain an oil phase, mixing the aqueous phase and the oil phase, and subjecting same to magnetic stirring and emulsification, so as to obtain a W/O emulsion; and (4) adjusting the pH of the W/O emulsion to be acidic, mixing the W/O emulsion and a salt buffer, leaving same to stand for 1-2 h, and then separating the oil phase from the aqueous phase, so as to obtain a liquid anthocyanin microcapsule. The anthocyanin prepared using a special preparation process can improve the yield and purity. The microcapsule preparation process can ensure the structural stability of the anthocyanin and reduce the cost thereof.
