Abstract

The purpose of this study is to predict multiplication patterns of foodborne pathogens according to packaging methods and storage conditions in home-delivered meals. Pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok which inoculated $10^6\;CFU/g$ of foodborne pathogens were packaged by wrap packaging, top sealing, vacuum packaging and stored at 25, 4 and $-18^{\circ}C$ during 5 days. The result of study was revealed that the growth and multiplication pattern of the inoculated foodborne pathogens was inhibited in chilling and freezing storage after vacuum packaging, and was significantly influenced by storage temperature. The survival of Listeria monocytogenes was also significantly influenced by storage period. The effective method to preserve the bacteriologic safety of pan fried oak mushroom and meat and soy sauce glazed hair tail in home-delivered meals was stored for maximum three days in chilling storage after vacuum packaging.

가정배달급식의 저장기간 중 식중독 발생에 대비하여 식중독균의 증식 양상을 사전에 예측하기 위한 기본자료를 얻고자 표고고기전, 갈치조림, 더덕구이에 주요 식중독 원인균을 접종하여 wrap 포장, 상압 및 진공포장 처리한 후, -18, 4, $25^{\circ}C$에서 5일간 포장방법 및 저장조건에 따른 변화를 살펴보았다. 가정배달급식을 위한 음식에 주요 식중독균을 접종한 결과, 식중독균의 성장 및 증식은 적용된 음식을 진공포장 처리하여 냉장 및 냉동저장시에 억제되는 것으로 입증되었고, 접종된 주요 식중독균의 포장방법 및 저장조건에 따른 성장 및 증식은 저장온도에 유의적인 영향을 받는 것으로 나타났으며, 특히, L. monocytogenes는 저장기간에 대해서도 유의적인 영향을 받는 것으로 나타났다. 따라서 표고고기전과 갈치조림의 냉장저장 시에는 L. monocytogenes가 저장 5일에 증가하므로 음식품질을 유지하고 식중독균 발생을 방지하기 위해서는 3일까지 저장하는 것이 바람직한 것으로 판단되었다.
