【 摘 要 】

The effect of modified atmosphere packaging (MAP) on the keeping quality of green mussel stored at 4C was investigated.Inhibition of the bacterial growth increased proportionally to the CO2 concentration in the packaging, and maximuminhibition was achieved with 100% CO2. Mussel stored under CO2-enriched atmosphere had lower total volatile base, trimethylamineand TCA-soluble peptide contents than those stored in air (P<0.05). However, the increase in exudate loss wasobserved for samples packaged in high-CO2 atmosphere, suggesting the denaturation of muscle proteins by carbonic acidformed. The odor and flavor acceptability of CO2-enriched packaged samples, particularly with 80 and 100% CO2, wasaccepted throughout the storage of 12 days, compared with six days for those stored in air. Therefore, MAP with 80% CO2,10% O2 and 10% N2 was chosen as the optimum condition for extending the shelf-life of green mussel. Packaging withinclusion of O2 should be considered to avoid the outbreak of strictly anaerobic toxin producing bacteria.
