Dioscorea opposita peptide polysaccharide composite nutrient solution prepared from dioscorea opposita serving as raw material and by biological enzyme method and preparation method of composite nutrient solution

Abstract

The invention relates to dioscorea opposita peptide polysaccharide composite nutrient solution prepared by comprehensive development and utilization of dioscorea opposita through biological enzyme engineering. The optimal process conditions of step enzymolysis of composite enzyme comprises the following steps of: 1)first step of enzymolysis technology condition, namely, the rate of solid to liquid is 1: (10-15), the enzyme addition quantity accounts for 0.1 to 0.2 percent of total amount, the enzymolysis temperature is between 65 and 75 DEG C, a pH value is 6.0 to 7.0, and time is 1 to 2 hours; 2) second step of enzymolysis technology, the enzyme addition quantity accounts for 0.1 to 0.5 percent of total pulp quantity, the enzymolysis temperature is between 50 and 60 DEG C, the pH value is 6.0 to 7.0, and the time is 3 to 4 hours. The dioscorea opposita is comprehensively developed and utilized by a biological enzyme engineering technology to prepare dioscorea opposita peptide polysaccharide composite nutrient solution, and the comprehensive utilization rate of the dioscorea opposita and active ingredient extraction are greatly improved; the developed dioscorea opposita peptide composite nutrient solution is rich in nutritive ingredients such as peptide, polysaccharide, amino acid and the like, and is comprehensive and rich in nutrition; by the process to prepare the dioscorea opposita peptide polysaccharide composite nutrient solution, the process has the characteristics of reasonable and simple production technology and easiness in industrial production; and the prepared dioscorea opposita peptide polysaccharide composite nutrient solution can be widely applied to various health-care food and health-care medicine.

Description

technical field [0001] The invention relates to a Chinese yam compound nutrient solution and a preparation method thereof, in particular to a compound nutrient solution of Chinese yam peptide and polysaccharide prepared by adopting a biological enzyme method and taking Chinese yam as a main raw material and its preparation method. The preparation method of the polysaccharide compound nutrient solution. Background technique [0002] Chinese yam is the tuber of Dioscorea opposita Thund, a perennial winding herb. According to the records of "Compendium of Materia Medica", yam is sweet and flat in nature, non-toxic, beneficial to kidney qi, strong bones and muscles, invigorating the spleen and stomach, stopping diarrhea, resolving phlegm and salivation, moistening fur, stopping diarrhea and amnesia, etc. It is a kind of superior medicine. Health food and traditional Chinese medicine materials. Yam contains various nutrients necessary for the human body: polysaccharides, protei...

AI Technical Summary

Problems solved by technology

However, the processing methods of Chinese yam are backward, and most of the processing methods used are knives, cutting boards, rubbing, drying, drying, etc. , dairy, frying and other processing methods, only to provide some crude products and semi-finished products

In recent years, some enterprises have introduced products such as canned Chinese yam and fruit tea of ​​Chinese yam, but they still haven’t got rid of the influence of backward traditional crafts, which greatly restricts the development and utilization of Chinese yam

This situation can neither meet the society's demand for high-tech Huai medicine products, but also greatly restricts the rapid growth of economic benefits and export earnings of Huai medicine processing enterprises, seriously affecting the vigorous development of Huai medicine industry.
