摘要: The changes were studied in microbiological, chemical, and sensory properties of Pacific oysters stored at 10 deg C, 5 deg C, and 0 deg C. Pseudomonas (22%) and Vibrionaceae (20%) species were dominant in raw oysters. The dominant bacteria found in the spoiled samples were Pseudomonas regardless of the storage temperature. During storage, rapid increases in aerobic plate count (APC) values of the samples stored at 10 deg C and 5 deg C were observed, while no obvious lag phases were detected. With thesamples stored at 0 deg C, a decrease in APC value during the first 4 days and a lag phase of about 6 days were observed. The APC values of the samples stored at 10 deg C, 5 deg C, and 0 deg C reached the level of 1~7 CFU/g on day 6,10, and 18, respectively. All the tested samples stored at different temperatures revealed a slight decrease in pH and a significant increase of total volatile basic nitrogen (TVB-N) during storage. The average TVB-N concentration of about 22.0 mg N/100 g was observed at the end of the shelf-life as determined by APC. Combined with the sensory assessments, the shelf-life of 6-7, 10-11, and 17-18 days for oysters stored at 10 deg C, 5 deg C, and 0 deg C, respectively, was determined.
