Problems solved by technology

[0003] Peptides are some special fragment sequences contained in proteins, fundamentally have a positive effect on human health, and can promote health after oral administration. Egg protein is rich in protein, and the peptides obtained after enzymatic hydrolysis have good degrading properties. Blood pressure effect, but the current protein and peptide acquisition process mainly has the problems of high production cost, low peptide acquisition rate, and low purity of the obtained peptide

Abstract

The invention relates to the technical field of acquisition of polypeptide products, and particularly relates to a method for acquiring polypeptide products from proteins. The method comprises the following steps: cooking eggs; acquiring proteins; crushing and adding deionized water; adjusting the pH value with malic acid; stirring for 8-10 min; drying the proteins recovered after reacting in water bath at a low temperature; dispersing at a high speed to obtain a dispersed material; uniformly mixing the dispersed material with sodium pyrophosphate at a weight ratio of 1000: 4-5; adding water to adjust the humidity of the dispersed material; inoculating saccharomyces albicans for fermentation treatment; mixing the dispersed material with the water uniformly; performing centrifugal treatment at a high speed; removing residues; concentrating supernatant; spray-drying a concentrated solution to obtain protein polypeptide products. The method for producing the protein polypeptide products, provided by the invention, has advantages of simple production process, low requirement on equipment, low cost, high yield of polypeptide and high purity; the obtained polypeptide products have significant effect on an aspect of decreasing blood pressure.

Description

technical field [0001] The invention relates to the technical field of obtaining polypeptide products, in particular to a method for obtaining polypeptide products from proteins.
