Abstract

Potato and sweet potato starch were formulated to be a product of BST exhibiting prebiotic activities. The BST were developed under different rasio of potato and sweet potato starch (A1 = 25:75; A2 = 50:50; A3 =75:25). The BST dough were mixed and prepared under different temperature of mixing (B1 = 60 °C; B2 = 70 oC and B3= 80 oC). Based on the overall sensory evaluation, the best formula was of potato and sweet potato starch 75:25. However, higher values of prebiotic index and short chain fatty acid content were observed from the formula of potato and sweet potato starch of 25:75, compare to that of the rasio 75:25. The possible reason of this was that the sweet potato contain higher resistant starch. Keywords: starch, prebiotic, retention RS, prebiotic index, SCFA

Abstract

The increasing of consumer demand has forced the small scale soy sauce factories to expand the quality and quantity of their production. However, they have a major problem on the duration of spontaneous fermentation for the production of moromi which take at least 2 months time. Therefore, an effort to shorten the fermentation time is proposed in this study by the applications of controlled fermentation using protease producing microbes. This study was aimed to compare the spontaneous and controlled fermentation of moromi using a single P. halophilus FNCC 0033 as well as a combination of P. halophilus FNCC 0033 and Z. rouxii FNCC 3008 as the inoculum for extended fermentation process of soybean in salt solution at pH 8.0. The quality parameter of moromi observed were pH, dissolved protein, total nitrogen, microbial count, and sensory evaluation by expert panelist. The result showed that controlled fermentation of moromi using both single P. halophilus FNCC 0033 or a combination of P. halophilus FNCC 0033 and Z. rouxii FNCC 3008 could shorten the duration of moromi fermentation time, from usually 8 weeks becomes 2 weeks only. The highest dissolve proteins content was detected in the moromi prepared by a single P. halophilus FNCC 0033 rather than its combination with Z. rouxii FNCC 3008. Moreover, result of sensory evaluation showed that P. halophilus FNCC 0033 fermented moromi exhibit more acidic flavor, indicating the ability of this lactic acid producing bacteria in producing both protease and lactic acids during the fermentation activity.
