Production process of biological peptides

In addition to extracting natural peptide components, the commonly used production methods include acid hydrolysis, enzymatic hydrolysis, microbial fermentation, and amino acid synthesis. The acid hydrolysis method is generally not adopted due to the difficulty in controlling product quality, and the amino acid synthesis method is also difficult to produce on a large scale due to high production costs. It is generally only used for human health production. Therefore, in industrial production, especially in the production of feed raw materials, enzymatic hydrolysis and microbial fermentation methods are usually used. The process flow is as follows:
Soy protein - Inoculation of bacterial strains - Fermentation and enzymatic hydrolysis - Low temperature drying - Crushing - Weighing and packaging

The difference between the products produced by the two process methods: active microbial cells directly participate in biochemical metabolism and act on large molecule soy protein; The biochemical metabolism of active microbial cells can modify certain functional groups; Active microbial cells can synthesize and secrete small peptide substances; Microbial fermentation method is different from enzymatic method, which simply cleaves peptide bonds; Many complex primary and secondary metabolites can be synthesized through microbial metabolism and fermentation, but enzymatic methods cannot; During the fermentation process, a large number of bacterial cells grow and reproduce. The cell wall of microbial cells is formed by the cross-linking of peptidoglycan, which is a polysaccharide peptide composed of N-acetylglucosamine and N-acetyl cell wall acid. Cell wall acid is a special substance of eukaryotic bacteria that does not exist in any other organism. Microbial cells not only have nutritional functions, but also stimulate the immune function of animal bodies.

Production equipment: The production equipment for biological peptides mainly includes mixing tanks, fermentation tanks, low-temperature drying systems, and micro crushing systems.
