摘  要：
在(4±1)℃冷藏条件下,采用40%CO2+10%O2+50%N2、60%CO2+10%O2+30%N2、80%CO2+10%O2+10%N2含不同体积分数CO2气调包装带鱼。以感官评分、细菌总数、挥发性盐基氮(TVB-N值)、pH值、硫代巴比妥酸(TBA值)和汁液流失率为指标,研究不同体积分数CO2气调包装带鱼在冷藏条件下品质的影响。结果表明,气调包装能够有效抑制细菌的生长繁殖,延缓挥发性盐基氮的上升,高体积分数的CO2抑菌效果较为明显,但随CO2体积分数升高,鱼样汁液流失严重;在抑制鱼样脂肪氧化方面,气调包装效果不明显。80%CO2+10%O2+10%N2气调包装能够显著延长新鲜带鱼的保鲜期至14d以上。

摘  要：
Trichiutus haumela samples packaged in controlled atmosphere with 40% CO2+10% O2+50% N2,60% CO2+10% O2+30% N2,or 80% CO2+10% O2+10% N2 were stored at (4 ± 1) ℃ for 14 days. Changes in sensory evaluation values,total bacteria count,total volatile base nitrogen (TVB-N),pH value,the 2-thiobarbituric acid (TBA) and drip loss were determined during the storage period to evaluate the effect of CO2 concentration in MAP environment on cold storage characteristics of Trichiutus haumela. It was showed that Trichiutus haumela had lower total bacteria count and total volatile base nitrogen in MAP environment than in normal atmospheric environment. High CO2 MAP had better antimicrobial effect,but drip loss became more serious with increasing CO2 concentration. MAP,however,did not obviously inhibit lipid peroxidation in Trichiutus haumela. MAP with a gas composition of 80% CO2+10% O2+10% N2 could extent the shelf-life of Trichiutus haumela to more than 14 days.
