Gold thread jujube peptide production method

Abstract

The invention discloses a gold thread jujube peptide production method. Jujube peptide is extracted from ultra-filtration cut-off solution (cut-off molecular weight is 150,000) processed by using concentrated jujube juice. The method comprises the following ten steps of: acid precipitation and elution, enzyme hydrolysis, ultra-filtration membrane separation, ion exchange, vacuum concentration, high-pressure homogenization, spray drying, sieving, packing, finished jujube peptide powder formation. The production method of the concentrated jujube juice comprises the following steps of: cleaning, rehydrating and pulping the jujube raw material, separating the pulp to obtain jujube pits, jujube paste and jujube juice, performing enzymolysis, pasteurization and ultra-filtration on the jujube juice, and concentrating the filtrate to obtain a concentrated jujube juice finished product, wherein the jujube raw material is selected from gold thread jujube. According to the jujube peptide production method, the jujube is subjected to effective biological extraction, the traditional process is replaced by adopting an advanced biotechnology, the active substances of the product are kept, the taste of the product is better, the process is advanced, the energy consumption is reduced, and an effective path is provided for deep processing of the jujube.

Description

Technical field [0001] The invention relates to the deep processing of agricultural products, in particular to a method for producing the golden silk jujube jujube polypeptide of the invention. Background technique [0002] In recent years, with the advancement of biotechnology and the development of life sciences, more and more attention has been paid to the physiological functions of polypeptides in organisms. A large number of research results show that, due to its large molecular weight and complex structure, protein is not easy to be digested and absorbed after ingested into the human body, which affects its physiological functions and effective performance of nutritional value. Polypeptides are simpler than proteins in structure and smaller in molecular weight. They consist of 2-16 amino acids connected by peptide bonds. According to the number of amino acids, they can be divided into short peptides (2-5 amino acids) and polypeptides (6-16 amino acids). ), is an intermedia...
