摘要

摘要: 在冰温下贮藏,研究不同的包装条件对军曹鱼品质的影响,确定冰温气调包装军曹鱼最佳气调包装参数。对照组为空气贮藏,实验组气体配比为6组,分别为100%N2、75%N2+25%CO2、50%N2+50%CO2、30%N2+65%CO2+5%O2、25%N2+75%CO2、100%CO2,包装袋以纯PE、一般阻隔性、高阻隔性3种材质的包装材料为对象进行研究,气调包装后在冰温袋-1.01⁰℃范围内贮藏,贮藏期间考察K值、挥发性盐基氮（TVB-N）含量、细菌总数和汁液流失率等品质指标的变化。结果表明,K值、TVB-N含量、细菌总数、汁液流失率均在贮藏期间有不同程度的增加,并且对照组和实验组有显著性差异（p<0.05）,以K值、TVB-N含量、细菌总数增长速度慢,汁液流失率少为评定标准,综合比较几种品质指标的变化规律,最终确定为使用高阻隔性包装袋并充以50%N2+50%CO2的气体配比进行冰温气调包装军曹鱼为最佳。

Abstract: Packaged cobia under different conditions during modified atmosphere packaging and freezing-point storage, the effects on the quality of cobia were studied to determine the best packaging parameter. The experimental group of different gas ratio were taken 100% N2, 75% N2+25% CO2, 50% N2+50% CO2, 30% N2+ 65% CO2+5% O2, 25% N2+75% CO2, 100% CO2as study object, and packaging bags of different materials were taken PE, general barrier property and high barrier as study object, the control group was air storage. Stored at a temperature range of-1.01 to 0℃ after modified atmosphere packaging, some quality indexes such as K value, TVB-N value, total bacterial number and drip loss were measured during storage. The results showed that, to varying degrees, an increase was founded for all indexes through the storage period, and there was significant difference (p<0.05) between the experimental group and the control group. Taken slower growth of K value, TVB-N value, total bacterial number and less drip loss as evaluation standard, after the comprehensive comparison of these quality indexes, the high barrier and a gas ratio of 50% N2+50% CO2were determined as the best modified atmosphere packaging and freezing-point storage parameter.
