Yeast Extract is a spray dried extract of autolyzed Brewer’s Yeast manufactured by complete autolysis i.e a transformation of proteins into peptides and amino acids, implemented through the enzymes present in the yeast. Beside peptides and amino acids, Yeast Extract also contains water-soluble vitamins i.e., B1-B2-B6, carbohydrates, purine and pyrimidine bases. Yeast extract is added to Culture Media, as a Vitamin source at concentrations of 3-5 g/l and is used for fast growth of bacteria for industrial fermentations. Yeast Extract can be used in nutrients and drinks. Yeast Extract can also be used in foodstuffs and for flavouring such as seasoning pack of instant noodles, instant soap, chicken powder, cookies, soy sauce, bulked food, cooling food and breads.
