THE CHEMICAL PROPERTIES COMPARATIVE OF YEAST HYDROLYSATE ENZYMATIC (YHE) FROM YEAST THAT FERMENTED IN RICE FLOUR VARIATION

摘要

YHE is a yeast extract from enzymatic hydrolysis. Yeast as a raw material for YHE can be fermented in white, red and black rice, which have different chemical compositions. This study aims to describe the chemical composition of YHE from fermented yeast in rice flour variation, hereinafter referred to as YHE-white rice (Y-WR), YHE-red rice (Y-RR), and YHE-black rice (Y-BR). The chemical composition measured was: Cr3+, Cr6+, % protein, amino ratio (N-α) /(NT) content,% crude fiber, and % starch. The results showed that YHE from yeast grown in black rice flour had the highest Cr3+, Cr6+, protein, amino ratio (N-α)/(NT) compared to YHE from yeast that fermented in white and red rice flour, and it had the lowest content crude fiber and starch.
