Yeast Extract is a versatile powder or granular form derived from protein-rich yeast, such as baker's yeast, meticulously processed to break down cell contents.
This breakdown occurs through advanced techniques like autolysis, enzymatic hydrolysis, or acid hydrolysis. The result is a treasure trove of free amino acids, small molecular peptides, B vitamins, nucleotides, minerals, and essential growth factors. It serves as a pivotal organic nitrogen source and nutritional supplement in microbial culture mediums. Depending on the specific processing method, it is categorized into the following distinct types:
Autolysis type: Boasting a low degree of hydrolysis, it is cost-effective and primarily utilized for industrial fermentation purposes.
Enzymolysis type: By employing a sophisticated array of enzymes, including protease and glucanase, this type undergoes moderate hydrolysis, making it rich in nucleotides and vitamins. It is ideal for laboratory settings and meets high standards of microbial culture.
Acid hydrolysis type: Characterized by a high concentration of free amino acids, albeit with increased salt content and Maillard reaction products, making it a popular choice in food industry seasoning applications.
