Utilization of Tofu Dregs into Soy Sauce: Study of the Proportion of Tofu Dregs Filtrate With Coconut Sugar on Soy Sauce Quality

Abstract

The study aims to determine the effect of treatment the proportion of filtrate tofu with coconut sugar to quality soy tofu. The design used a randomized block design (RBD) consisting of six treatments with the proportion of pulp filtrate: coconut sugar is A (125 ml: 157.5 grams) , B (125 ml:172.5 grams), C (125 ml:187.5 grams), D (125 ml:202.5 grams), E (125 ml:217.5 grams), F (125 ml:232.5 grams) and repeated three times. The variables measured include chemical analysis (protein content, water content, sucrose concentration , pH), organoleptic test (flavor, aroma, color) and viscosity. The results showed: (i) the difference is very noticeable effect on protein content, sucrose concentration, pH, aroma, taste and viscosity , (ii) the difference was not significant on the moisture content and color and (iii) the best treatment is the proportion of the filtrate tofu with coconut sugar 125 ml: 232.5 grams of soy pulp that produces the protein content of 1.144 %, 2.109 % sucrose content, water content of 49.497 % , 6.630 % and the pH value organoleptic a taste panelists to 3,333 (regular), aroma 3,667 (love), color 3.467 (regular) and viscosity of 3.467 (normal).
