Yeast Extract is an exquisite powder or granular formulation derived from protein-rich yeast strains like baker's yeast. These strains undergo a meticulous process that degrades cell contents to harness the power of yeast.
This transformation occurs through autolysis, enzymatic hydrolysis, or acid hydrolysis. Yeast Extract boasts a rich composition of free amino acids, small molecular peptides, vital B vitamins, nucleotides, essential minerals, and growth factors. It stands as a pivotal organic nitrogen source and a premier nutritional supplement within microbial culture media. Depending on the specialized processing technology employed, Yeast Extract is categorized into the following distinguished types:
Autolysis type: Exhibiting a minimal degree of hydrolysis, this cost-effective variant is primarily deployed for industrial fermentation processes.
Enzymolysis type: Through the sophisticated application of complex enzymes such as protease and glucanase, this type undergoes moderate hydrolysis. It is abundant in nucleotides and vitamins, making it ideal for laboratory settings and applications demanding high microbial culture standards.
Acid hydrolysis type: Characterized by a high concentration of free amino acids, this type includes more salt and Maillard reaction products, thus finding extensive utility in the food industry as a seasoning agent.
