Physiological active buck peptide by compound proteinase catalysis and use of products thereby

Abstract

This invention relates to preparation of deer peptide with biological activity by composite protease catalysis and its uses in human immunity, fatigue resistance and hypoxia tolerance. Products are obtained by heating deer meat paste as raw material, which is screened with 80 mesh, to 48-52 deg.C, regulating pH 6.8-7.2 with NaOH solution, stirring and adding neutral protease, papoid or trypsin, then adding fragrant protease after protein hydrolysis to 28-33%, controlling reaction with standard 2M NaOH to make protein hydrolysis to 34 -42%, heating enzymolysed liquid to 114-116 deg.C for 10-15 minutes, sharply cooling to atmosphere, solid-liquid separating, concentrating, and drying to obtain yellow powder or granular products of deer peptide.

Description

technical field

[0001] The invention belongs to the field of biochemistry, and in particular relates to a deer peptide product with physiological activity prepared by hydrolyzing venison with a method catalyzed by a compound protease, and the deer peptide product can improve immunity of the body, enhance fatigue resistance and hypoxia resistance, etc. aspects of application. Background technique

[0002] Physiologically active peptides are the most popular research topics in the current food science field. They are generally produced from proteins through enzyme action. Different products can be produced due to different raw protein, hydrolytic enzymes, and separation and refining methods; peptides, especially some oligopeptides Not only has better digestion and absorption performance than protein, the most exciting thing is that some peptides have been found to have physiological activities such as regulating human physiological functions, preventing and resisting diseases,...
