Abstract

The invention discloses a nutritive matrix containing rich essential amino acid and a production method and application thereof. The production method includes the steps that aspergillus and glucose are inoculated to sterilized peanut meal to be fermented so as to obtain peanut meal fermented koji; protease is added into the fermented koji for control enzymolysis, ethyl alcohol is then added until the content reaches 70-90%, and supernate obtained by constant-speed stirring and centrifugal separation is peanut meal enzymatic hydrolysate containing rich essential amino acid; after enzymatic hydrolysate is concentrated, active dry yeast is added, the mixture passes through an ultrafiltration membrane, beta-cyclodextrin and citric acid are added into permeating liquid, then spraying drying is performed, and the nutritive matrix containing rich essential amino acid is obtained. A high-concentration alcohol deposition method and a membrane separation method are combined, through high-concentration ethyl alcohol treatment, necessary components high in essential amino acid are gathered, and then in combination with membrane separation, polypeptide and other substances are obtained, wherein the high molecular weight of polypeptide and other substances is below 5000 Da; the purposes of efficiently separating target substances and gathering essential amino acid are achieved, and the technological process is simplified.

Description

technical field [0001] The invention relates to a nutritional base material rich in essential amino acids, its production method and application. Background technique [0002] Amino acid is an important component of all cells and tissues in the human body, and is closely related to the growth and development of adolescents, the prenatal and postnatal care of pregnant and lying-in women, and the health and longevity of the elderly. There are only more than 20 amino acids that make up human protein, most of which can be directly synthesized in the human body or transformed from other amino acids, and a few amino acids cannot be synthesized in the human body or the synthesis speed is slow and must be supplied by food protein. Amino acids are commonly called essential amino acids in nutrition, namely isoleucine, leucine, lysine, methionine, phenylalanine, threonine, valine and tryptophan. [0003] Survey statistics show that the per capita protein intake of Chinese residents is...
