초록
This study was conducted to evaluate the effect of gamma irradiation on the microbialpopulations of dried raw materials (9 products) and Saengsik powder. The samples were gammairradiatedat doses of 2, 4, 6 and 8 kGy and the microbiological populations were evaluated. Thetotal numbers of bacteria and Bacillus cereus in non-irradiated dried-raw materials for Saengsikpowder was 1.3~3.4 and 1.7~2.4 log CFU g-1. However, gamma irradiation reduced the microbiologicalpopulations in all samples, and Saengsik powder were sterilized at more than 6 kGy. Moreover, Clostridium perfringens were not observed in all samples within detection limit (⁄1 logCFU g-1). Therefore, the results of this study suggest that gamma irradiation at 6 kGy is sufficientto sterilize Saengsik powder, and thus, irradiated Saengsik powder at 6 kGy fulfills the microbiologicalrequirements for sterilized food.
