Yeast Extract is a powder or granular product made from protein-rich yeast (such as baker's yeast) that degrades cell contents
through autolysis, enzymatic hydrolysis or acid hydrolysis. Its main components include free amino acids, small molecular peptides, B vitamins, nucleotides, minerals and growth factors, and it is an important organic nitrogen source and nutritional supplement in microbial culture medium. According to the different processing technology, it is divided into the following types:
Autolysis type: low degree of hydrolysis, low cost, mainly used for industrial fermentation.
Enzymolysis type: Through complex enzymes (protease, glucanase, etc.) treatment, moderate hydrolysis, rich in nucleotides and vitamins, suitable for laboratory and high requirements of microbial culture.
Acid hydrolysis type: high content of free amino acids, but more salt and Maillard reaction products, more used in food industry seasoning.
