|
This study was performed to provide basic data for the sous vide cook-chill(SVCC) System by comparing and evaluating food quality, according to preparation method and days of storage, of foods that were prepared by SVCC to those prepared using the cook-chill(CC) System. Boiled quail eggs and fish paste in soy sauce were prepared using CC and SVCC and their quality was evaluated at the time of preparation and by days of storage. Viable cell counts were increased to 5.65(CC) and 3.40(SVCC) LogCFU/g by 15 days(p<.0001) and increased more over time in foods prepared with CC than with SVCC. For the CC method, Coliform counts increased to 4.58 LogCFU/g by 15 days(p<.0001). With SVCC, colirorms were not detected at 0 days, but counts reached 3.70 LogCFU/g bv 15 days(p<.0001). After reheating, no coliforms were detected fot CC or SVCC at 0 days, however, by 15 days, coliform counts reached 3.61 and 2.52 LogCFU/g(p<.0001) for CC and SVCC, respectively. Finally, the sensory scores of SVCC were higher than those of CC.
