Abstract

Soy sauce as one of the soy fermented product could be produced through fermentation by molds and then fermentation by bacteria and yeasts, in salt solution (moromi). The aims of this research were to evaluate and to compare the value of carbohydrate), lipid, and protein in soy sauce which were produced from tempe by mixing Rhizopus oligosporus and R. oryzae with and without moromi fermentation; to compare the taste, aroma and color of soy sauce have been produced and commercial soy sauce, i.e. Bango and Lombok Gandaria. The value of carbohydrate (reducing sugar and starch), lipid, and protein in soy sauce which were produced by mixing of R. oligosporus and R. oryzae with difference treatment by moromi and without moromi fermentations, were analyzed. The satisfaction test was conducted to compare the taste; aroma and color between soy sauce have been seasoning, and the commercial soy sauce Bango and Lombok Gandaria. Soy sauce could be made from tempe without moromi fermentation. Protein and lipid value of soy sauce from tempe without moromi fermentation were higher than soy sauce from tempe with moromi fermentation; such as lipid, but not significantly. Carbohydrate value of soy sauce from tempe without moromi fermentation was lower than soy sauce from tempe with moromi fermentation. Soy sauce from tempe without moromi fermentation had the taste and aroma which more preferable than soy sauce from tempe with moromi fermentation.
