Yeast Extract is a meticulously crafted powder or granular product derived from protein-rich yeast sources, such as baker's yeast, where it undergoes a process of cell content degradation.
This is achieved through sophisticated methods such as autolysis, enzymatic hydrolysis, or acid hydrolysis. The extract is a powerhouse of nutrients, comprising free amino acids, small molecular peptides, essential B vitamins, nucleotides, minerals, and growth factors. It serves as a pivotal organic nitrogen source and a nutritional supplement in microbial culture media. The types of yeast extract vary based on processing techniques:
Autolysis type: Exhibits a lower degree of hydrolysis and is cost-effective, making it ideal for industrial fermentation applications.
Enzymolysis type: This variant undergoes treatment with complex enzymes, such as protease and glucanase, resulting in moderate hydrolysis. It is rich in nucleotides and vitamins, making it perfect for laboratory settings and high-standard microbial culture.
Acid hydrolysis type: Known for its high content of free amino acids, though it also contains more salt and Maillard reaction products. This type finds its application primarily in the food industry for seasoning purposes.
