摘  要：
研究N_2和CO_2不同比例混合对气调包装秋刀鱼在冷藏条件下pH值、菌落总数和挥发性盐基氮(total volatile basic nitrogen,TVB-N)值等理化指标和感官评价的影响。结果表明:40%CO_2+60%N_2混合气体气调包装秋刀鱼各项指标的变化速率明显低于其他各组(P<0.05),其他各组秋刀鱼在第9天时菌落总数已超过国家标准4.0(lg(CFU/g)),发生腐败变质,生成不良气味,而40%CO_2+60%N_2组则将这一现象推迟3 d,延长至12 d,CO_2气体比例过高或过低均会加速气调包装秋刀鱼的腐败变质。

摘  要：
This research was concerned with the effect of modified atmosphere packaging(MAP) using different N_2 and CO_2 combinations on the changes in physicochemical properties such as pH,aerobic plate count and total volatile basic nitrogen(TVB-N) as well as sensory evaluation of Pacific saury during cold storage.The results showed that the atmosphere consisting of 40% CO_2+60% N_2 significantly slowed down the rates of change of all investigated parameters when compared with other groups(P<0.05).On day 9 of storage,the fish in the other groups showed an aerobic plate count higher than the national standard limit of 4.0(lg(CFU/g)),being spoiled and smelling bad.The 40% CO_2+60% N_2 group delayed this phenomenon by three days and extended the shelf life to 21 days.However,both too high and too low CO_2 concentrations accelerated the spoilage process of modified atmosphere packaged Pacific saury.
