Yeast Extract is a meticulously crafted powder or granular product, sourced from protein-rich yeast like baker's yeast, meticulously breaking down cell contents.
This degradation is achieved through a sophisticated process involving autolysis, enzymatic hydrolysis, or acid hydrolysis. The composition is a rich blend of free amino acids, small molecular peptides, B vitamins, nucleotides, minerals, and essential growth factors. It serves as an indispensable organic nitrogen source and nutritional supplement in microbial culture media. Depending on the processing technology, it categorizes into distinguished types:
Autolysis type: Characterized by a low degree of hydrolysis and cost-efficiency, it is primarily utilized in industrial fermentation processes.
Enzymolysis type: Processed using sophisticated enzymes such as protease and glucanase, it offers moderate hydrolysis and is rich in nucleotides and vitamins, making it ideal for laboratory settings and demanding microbial culture applications.
Acid hydrolysis type: Distinguished by a high concentration of free amino acids, although it contains more salt and Maillard reaction products, it is frequently employed in the food industry as a flavor enhancer.
