<![CDATA[The purpose of this research is to obtain the best combination of treatments between the soaking time of sodium metabisulfite (Na2S2O5) and the drying time of the physico-chemical of tofu pulp flour. This research was conducted with nine treatment combinations and three replications. The treatment used was soaking time (L) and drying time (P). L1P1 (15 minutes, 3 hours), L1P2 (15 minutes, 4 hours), L1P3 (15 soaking, 5 hours), L2P1 (30 minutes, 3 hours), L2P2 (30 minutes, 4 hours), L2P3 (30 minutes, 5 hours), L3P1 (45 minutes, 3 hours), L3P2 (45 minutes, 4 hours), L3P3 (45 minutes, 5 hour). The treatments of selected in this research was L3P1 with water content of 6.47 %, ash content of 1.92 %, protein content of 17.03 %, and sensory assessment produced a rather white color with a score of 3.77, the aroma was rather unpleasant with a score of 3.07, and a rather subtle texture with a score of 3.60.]]>
