Abstract

The objective of this study was to investigate the effect of kecombrang flower extract addition and soaking time on physical, chemical and microbiology characteristics of fresh tofu during storage at room temperature. The research was conducted at Chemical of Agricurtural Product Laboratory and Laboratory of Food Microbiology, Agricurtural Technology Department, Agricurtural Faculty, Sriwijaya University from November 2018 to May 2019. The research used Factorial Completely Random Design with two factors and each treatment was repeated three times. The first factor was the concentration of kecombrang flower extract (0, 2, 4 and 6%) and the second factor was soaking time (0, 1, 2 and 3 days). The observed parameters were physical (texture), chemical (moisture content and pH values), and microbiological (total microbial population). The result showed that kecombrang flower extract addition had significant effect on texture, moisture content, pH values and total microbial population. On the other hand, soaking duration showed significant effects texture, moisture content pH value and total microbial population. Furthermore, interaction of the factor had significant effect only on total microbial population. Soaked tofu in kecombrang extract and soaking time can’t preserve tofu, but it can inhibit the growth of microbial population up to 0,07 log CFU/ml.
