Based on microbiological-chemical test results under simulated time-temperature conditions, total plate count, coliform and volatile basic nitrogen were selected as effective quality indicators for estimating probable shelf-life of Kim Pab dosirak marketed in convenience stores, and shelf-life at each storage temperature was calculated from regression equation between effective quality indicator standard limit and storage time. Estimated shelf-lives of Kim Pab Dosirak were 27, 3 and 2 hours respectively under 10℃, 20℃ and 30℃. Because shelf-life was especially affected by initial values, regression analysis between initial effective quality indicator values and storage hours was performed for the estimation of probable shelf-life of Kim Pab during storage at 10, 20 or 30℃.
