시판 진미채의 미생물학적 오염도 평가

초록

The aim of this study is to investigate the microbial contamination assessment of raw Jinmichae to cook and to establish its control. Three kinds of Korean Jinmichae products (K1, K2, K3) and three kinds of imported Jinmichae products (Chile: F1, Peru: F2, Mexico: F3) were collected from markets and department stores in Seoul and Gyeonggi-do. The results were as follows; Aerobic mesophilic bacteria in raw Jinmichae (F2) was detected 7.20×107 CFU/g, which exceeded the acceptable standard level, 1.0×106 CFU/g. The rest of raw groups fell up to 1.0×103～1.0×104 CFU/g. Aerobic mesophilic bacteria were detected in blanched and fried Jinmichae groups. Boiled Jinmichae group did not exceed the acceptable standard level of 1.0×106 CFU/g. However, all the fried groups exceeded the level. E. coli were detected in raw Jinmichae but it was able to be controlled by blanching. Unlike this, E. coli was not completely controlled by roasting for 20 seconds relative to 40, 60 seconds. S. aureus were effectively controlled by boiling, however, it was not controlled by roasting. After roasting Jinmichae for 60 seconds, S. aureus were detected in the half of all groups. In this study, Jinmichae were found to be favorable one of side dishes in school meal service. Jinmichae can be contaminated by microbial pathogens such as S. aureus, E. coli, etc. Therefore, further studies are needed to monitor microbial pathogens and to provide their control.
