The feeding yeast protein «EXTRA» is presented as the brewer’s yeast autolysate (BYA).
The feeding yeast protein “EXTRA” features protein according to Barnstein within the range of 37-40% and actual absence of non-protein hydrogen.
The important advantage of the feeding yeast protein “EXTRA” is its use as a raw material for Saccharomyces brewer’s yeasts, which absorb all the valuables that are contained in grains and multiplied by a yeast cell in the process of beer maturation. The yeast cells contain 40-54% of protein and 18% of glycogen, they are reach of group B vitamins, mineral salts and indispensable amino acids. In terms of the amino acid content, the feeding yeast protein «EXTRA» is close to animal feeds.
