Chinese yam polysaccharide, Chinese yam healthcare wine and production method thereof

Abstract

The invention belongs to the technical field of food processing, and in particular relates to a Chinese yam polysaccharide, a Chinese yam healthcare wine and a production method thereof, aiming to solve a first technical problem of providing a Chinese yam polysaccharide and a preparation method thereof. As the Chinese yam polysaccharide is extracted by using alpha-amylase and saccharifying enzyme in an assistant manner, mere water extraction is avoided, the problem that the Chinese yam polysaccharide cannot be completely released as starch granule wrapping constraint is not broken can be solved, through enzymolysis, starch granules can be broken, dissolution of the Chinese yam polysaccharide can be promoted, and thus the yield of the Chinese yam polysaccharide is remarkably increased; and furthermore, starch mixed in an extract can be effectively eliminated, so that the purity of a crude polysaccharide in the obtained extract can be greatly increased. The Chinese yam healthcare wine prepared by using the method provided by the invention is light golden yellow in color, has wine fragrance and taste and flavor and smell of certain medicinal raw materials, is free of odor, and has very good market prospects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a yam polysaccharide, a yam health wine and a production method thereof. Background technique [0002] Chinese yam, scientific name Dioscorea, Latin name Dioscorea opposita, also known as yam, sweet potato, yam, is the tuber of Dioscorea (Dioscorea) plant in Dioscoreaceae (Dioscoreaceae), and belongs to medicinal and edible resources. The dried rhizome of yam is included in the Pharmacopoeia. It is sweet in taste and flat in nature, and belongs to the spleen, lung and kidney meridian. For insufficiency of the spleen, lack of food, loose stools, excessive leucorrhea embolism. [0003] From the perspective of traditional medicine, yam is an excellent medicinal material that promotes the improvement of human immunity. On the other hand, the solid matter accounts for about 20% in fresh yam. The solid contains a variety of nutrients and functional ingredients, i...

AI Technical Summary

Problems solved by technology

[0006] The first technical problem to be solved by the present invention is to provide a yam polysaccharide and its preparation method, which uses α-amylase and glucoamylase to assist in the extraction of yam polysaccharide, which avoids simple water extraction and does not break the bondage of starch granules. The problem that the polysaccharide cannot be completely released - through enzymatic hydrolysis, the starch granules are cracked, the dissolution of the yam polysaccharide is promoted, and the yield of the yam polysaccharide is significantly improved; the starch mixed into the extract is also effectively removed, greatly improving The purity of the crude polysaccharide in the obtained extract
