Method for preparing bitter-free plant oligopeptide

Abstract

The invention discloses a production method for preparing enzymolysis plant oligopeptide of bitter-free plant oligopeptide. The method comprises the following steps of selecting food-grade plant protein as a raw material, adding enzyme for hydrolysis, adding acid and alkali in the hydrolysis process to maintain the pH value of a hydrolysate at 9.0+ / -0.5 and the hydrolysis degree at 40%-60%, centrifugally clarifying the hydrolysate at a high speed for 7-8 hours, finely separating a membrane, performing concentration and sterilization, and performing spray drying to obtain the bitter-free plantoligopeptide. The temperature is monitored at any time through a thermometer used in industrial production, and then fuel is supplemented at any time, so that the temperature is kept unchanged, and the enzymolysis time is prolonged to 7-8 hours. According to the method, the annual output can reach 200 tons, and the yield of obtained small molecular active peptides reaches up to 70-90%.

Description

technical field [0001] The invention relates to the application of enzymatic hydrolysis and a production method of plant oligopeptides, in particular to a production method of enzymolysis plant oligopeptides for preparing non-bitter taste plant oligopeptides. Background technique [0002] Peptides are linear polymers of amino acids. Those containing more than 50 amino acid residues are usually called proteins, and those with less than 50 amino acid residues are called peptides. The simplest peptide consists of two amino acid residues, called dipeptides, and peptides containing 3, 4, and 5 amino acid residues are called tripeptides, tetrapeptides, and pentapeptides, respectively. Generally, peptide chains containing several to a dozen amino acid residues are collectively called oligopeptides, and longer peptide chains are called polypeptides (polypeptides). Some scholars refer to those with more than 12 but not more than 20 amino acid residues as oligopeptides, and those wit...

Problems solved by technology

Through searching, we found that there is no literature report that industrial production can be obtained by enzymatic method, the yield is high, and the amino acid composition ratio of plant oligopeptides (17 kinds of amino acids required by the human body) is not changed, and the beneficial physiological properties of plant oligopeptides are not destroyed.
