Title:
PH-SENSITIVE STARCH-BASED MICROCAPSULE AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/087904
Kind Code:
A1
Abstract:
Provided are a pH-sensitive starch-based microcapsule embedded with a fat-soluble functional factor, and a method for preparation thereof, belonging to the field of preparation of starch-based hydrogel microcapsules. In the present method, starch is subjected to acid hydrolysis to obtain acidolysis carboxymethyl starch, then mixed with xanthan gum to obtain a compound solution of starch and colloid; then emulsifier and fat-soluble functional factor are added, and emulsification is performed to obtain an emulsion; drying is carried out to obtain microcapsules. The microcapsules prepared by the present method can resist the hydrolysis of gastric acid and enzymes in gastric juice, improving the bioavailability of fat-soluble functional factors in core material; the release rate in simulated gastric juice is only 20-40%, while the cumulative release rate in the human upper digestive tract (simulated gastric fluid and simulated intestinal juice) can reach 80-95%, solving problems such as the poor solubility of fat-soluble functional factors, easy oxidation, and low oral utilization; the invention can be used as a nutrition enhancer or food additive in beverages and other products, and has broad prospects for application.
