Problems solved by technology

[0005] However, the disadvantage is that EGCG has poor stability and is easily affected by factors such as temperature, water, pH, etc., especially when it is stored in a liquid environment for 7 days, its hydrolysis / degradation rate reaches more than 17%, even in a solid state, Although the stability will be relatively improved, it is more sensitive to temperature and will gradually degrade in a hot environment, which will seriously affect product quality and the development of EGCG preparations / products, and have serious adverse effects on product preparation, storage, circulation, etc.

Abstract

The invention provides a solid alcohol solid dispersion combination of EGCG (epigallocatechin gallate) with thermal stability and sugar alcohols. The sugar alcohols include one or more ingredients comprising fructose, newtol, fructo-oligose, xylooligosaccharide, polydextrose, mannitol, cane sugar, glucose, resistant dextrin, sorbitol, maltose, isomalt, mannose oligomer, carbo wax, dextrin, cyclodextrin, hydroxyl-lpropyl-beta-cyclodextrin, microcrystalline cellulose, carboxymethylcellulose, pregelatinized starch, starch, starch sugar, lactose, sodium carboxymethyl starch, proteoglycan, sucralose, aspartame, acesulfame, stachyose, neotame and stevioside, and the sugar alcohols and the EGCG are in (12-80):1 in proportion by weigth. The invention further provides a preparation method of the solid dispersion combination and application in preparation of the solid dispersion combination. By the aid of the solid dispersion combination, the EGCG is effectively improved in stability.
