Yeast Extract

Yeast Extract is a highly refined nutrient source derived from protein-rich edible yeast. Manufactured through advanced biotechnological processes—including autolysis, enzymatic digestion, separation, and concentration—this product effectively degrades yeast cell proteins and nucleic acids into a highly soluble paste or powder.
 
As a primary ingredient in the formulation of microbial culture media, it provides an exhaustive nutritional profile consisting of peptides, amino acids, flavor nucleotides, B-complex vitamins, and essential trace elements. These components work synergistically to support robust microbial growth and metabolic activity.
