Abstract
Research has been conducted to determine the chemical and physical characteristics of Yeast Hydrolysis Enzymatic (YHE) based on its fermentation media. The fermentation medium used is white, red, and black rice. The procedures carried out include the sample preparation, the fermentation, making pineapple crude and the enzymatic hydrolysis stage. In this study measured Cr3+ content using voltammetry method, and measurement of protein content using Kjehdahl method. There are three kind of YHE: YHE from yeast which is grown in white rice (YHE-Er), red rice (YHE-Rr) and black rice (YHE-Br). YHE from yeast grown in various growth media has different Cr3+ content. The lowest yield of Cr3+ was YHE-Wr which was 32 × 10−5% while YHE-Br was 37 × 10−5% and YHE-Br was 40 × 10−5 %. The protein content of YHE-Wr, YHE-Rr and YHE-Br were respectively 38.45; 38.48; and 39.23%.
