Abstract

The invention relates to a preparation method of crocin double-layer coated microcapsules, which is characterized by comprising the following steps: A, weighing crocin, a metal chelating agent, tremella polysaccharide, an auxiliary color agent, an emulsifier, a high-molecular polymer, grease and the balance of water according to a mass ratio; b, crocin, a metal chelating agent, tremella polysaccharide and an auxiliary color agent are mixed and then added into water, and the mixture is stirred to be uniform to serve as a water phase; c, mixing and uniformly stirring an emulsifier, a high-molecular polymer and grease to serve as an oil phase; d, adding the water phase and the oil phase into a high-pressure homogenizer, and homogenizing to obtain crocin single-layer coated microemulsion; e, preparing an external water phase; f, coating the crocin single-layer coated micro-emulsion and an outer water phase, and adding the crocin single-layer coated micro-emulsion into the outer water phase through an SPG membrane emulsification method to obtain a micro-capsule suspension; and G, carrying out spray drying on the microcapsule suspension to obtain the crocin double-layer coated microcapsule. The product disclosed by the invention has the advantages that crocin is not easy to fade and good in stability.

Description

technical field [0001] The invention relates to the technical field of sustained-release microcapsules, in particular to a preparation method of double-layer-wrapped microcapsules of crocin. Background technique [0002] Crocin is the only water-soluble carotenoid compound that exists in nature, widely exists in saffron, also known as crocin or crocin. At present, it is mainly used as a natural colorant in the food, dye, and cosmetic industries. Crocin is a series of ester glycosides composed of crocus acid and different sugars, mainly including crocin I, crocin II, crocin III, crocin IV, etc. The content of safflower I was the highest, accounting for about 70% to 80%. Crocin is easily soluble in water to form a transparent yellow solution, soluble in ethanol and propylene ester, but insoluble in oil. In the current industry, crocin is often directly added to the product, but the stability of crocin is poor, and it will cause inactivation and fading when exposed to heat, ...
