우리의 식탁에 사용 빈도가 높은 강낭콩조림을 선정하여 전통적으로 조리되는 과정과 재료의 혼합비를 파악하고 보존 hurdle로서 가열조리조건을 조절하여 강낭콩조림의 저장 안전성을 향상시키고자 하였다. 강낭콩 150g 기준에서 설탕 40g, 간장 30g, 물엿 30g인 배합비 하에서 가열조리시간을 25-50분으로 달리하여 조리하여 제품을 가공한 다음, 에서 20일간 저장 중 품질 변화를 측정하였다. 장시간의 가열조리인 50분 가열에서는 저장 10일째

We optimized braising time to improve the storage quality of braised kidney beans. The beans were prepared with different heating times between 25 and 50 min. and then stored at for 20 day. Physical, chemical, microbiological, and organoleptic quality indices were monitored throughout storage. Longer braising times yielded products with lower concentrated brine coverage. Bis resulted in higher soluble contents and slightly lower water activities. Excessive heating time exposed the kidney beans to air and caused rapid microbial growth on the surfaces of the beans, which negatively affected product quality. The longest heating time of 50 min. also resulted in a large increase in product hardness. A braising time of 30 min. was best for preservation, as good sensory quality was mainatained.
