title: Effects of Modified Atmosphere Packaging, Food Life Extenders and Temperature on the Shelf Life of Ready-Made Dishes.
abstract: The combined effect of several microbial control factors including gas barrier of containers, modified atmosphere packaging, food life extenders and storage temperature was discussed in order to determine the possibility for improving the shelf life for hamburger steak and deepfried chicken, representative ready-made dishes sold at convenience stores in Japan. Multiple measures including cold storage were effective in improving the shelf life of ready-made dishes. It was also suggested that storage tests for ready-made dishes should be conducted at 10℃, a practical temperature, to confirm the storable period, as well as at 15℃, an adequate abuse temperature, to confirm the effects of various microbial control factors. In the present study, the test group 4 (nitrogen + barrier containers + pH modifier) performed most favorably at both temperatures, indicating the efficacy of multiple means including "cold storage" in improving the shelf life (extending the consume-by date) of ready-made dishes. All strains isolated from the tested hamburger steak and deep-fried chicken were common food contaminant bacterial species.
