  • This study was performed to provide basic data for the operation of the sous vide cook-chill system(SVCC) by comparing and evaluating the quality of SVCC prepared foods to those prepared using the cook-chill system(CC). Foremost, the microbial risk was less and the food quality excellent when SVCC was used compared to CC, where changes in pH, Aw and moisture loss were less with SVCC. The CC and SVCC Aw value were 0.93 and 0.92 and 0.92 and 0.95 at 0 days and 15 days, respectively. Secondly, the microbial quality by storage days was relatively high with SVCC. The CC and SVCC viable cell and coliform counts were 4.43 and 4.37 LogCFU/g, and 4.53 and 3.60 LogCFU/g, respectively, by 15 days. Also, after reheating, the viable cell and coliform counts satisfide the standards applied in processed food(5.0 and 2.0 LogCFU/g respectively). Lastly, the sensory scores for SVCC were higher than those for CC. Thus, microbial and sensory qualities by days of storage were acceptable and overall quality satisfaction was better for SVCC than CC.
