Abstract

The invention belongs to the technical field of food processing, and particularly relates to an extraction method of Chinese wolfberry polysaccharide , a Chinese wolfberry polysaccharide tablet and apreparation method thereof. The Chinese wolfberry polysaccharide is prepared by carrying out first water extraction on dry Chinese wolfberry, and filtering to obtain a first extract liquid and filterresidues of the first extract liquid; carrying out second water extraction on the filter residues of the first extract liquid, and filtering to obtain a second extract liquid and filter residues of the second extract liquid; mixing the first extract liquid and the second extract liquid, filtering, and carrying out enzymolysis to obtain an enzymolysis extract liquid; filtering and concentrating theenzymolysis extract liquid to obtain a concentrated extract liquid; and mixing the concentrated extract liquid with ethanol, standing and centrifuging to obtain the Chinese wolfberry polysaccharide.By adopting the method provided by the invention, a polysaccharide product with the purity of 90% or above can be obtained, and the extraction rate reaches 85% or above.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for extracting wolfberry polysaccharides, wolfberry polysaccharide tablets and a preparation method thereof. Background technique [0002] Lycium barbarum polysaccharide is a kind of polymer polysaccharide extracted from Lycium barbarum. Its molecular weight is between 50,000 and 150,000. A water-soluble polysaccharide, which is the most important active ingredient in Lycium barbarum, has multiple functions and can be widely used in food, medicine, cosmetics and other industries. At present, it has become a research hotspot at home and abroad. [0003] However, most of the Lycium barbarum polysaccharides sold in the market are crude extracts of Lycium barbarum at present, with low extraction rate, complex composition and low purity. Contents of the invention [0004] The object of the present invention is to provide a method for extracting Lycium ...
