Abstract:
Fermentation of star fruit juice was conducted to produce vinegar using the yeast Saccharomyces cerevisiae and Acetobacteracetibacteria. Results are as follows: ethanol fermentation: soluble dry matter 9.21 oBrix, pH 4.3, yeast supplementation from 14.106cfu/ml to16.106cfu/ml, fermentation time 7 days, ethanol concentration 7-8%. acetic acid formation by traditional method: ethanol concentration 7%, pH 3.5, acetobacter 15%, fermentation time 25 days, acetic acid achievement 43-48 gram/litre. Acetic acid formation by quick method: ethanol 7%, pH 3.5, acetobacter20%, fermentation time 6-7 days.
