摘　　要： 研究了PP/CPP(聚丙烯+流延聚丙烯)、PET/CPP(聚对苯二甲酸乙二酯+流延聚丙烯)和PVDC/CPP(聚偏二氯乙烯+流延聚丙烯)3种不同包装材料对气调包装[(3±1℃,75%CO2+25%N2]鱼糜制品(鱼丸)货架期的影响,对菌落总数、挥发性盐基氮值、pH值、感官品质等影响货架期的因素进行了分析。结果表明:使用阻隔性较高的PVDC/CPP和PET/CPP的包装材料,冷藏气调鱼丸的菌落总数、pH值、TVB-N、感官指标均好于PP/CPP材料;3种包装材料优劣依次为:PVDC/CPP材料>PET/CPP材料>PP/CPP材料,对应的货架期分别为42、28、21d。高阻隔性的包装材料有利于保持冷藏气调包装鱼丸的品质,可有效限延长鱼丸的货架期。 The quality and shelf-life of the modified atmosphere packaging（MAP） surimi product（fishball） was studied under three different packaging materials.The aerobic plate count,pH value,TVB-N value and sensory index was determined to evaluate the qualities and shelf-life of the surimi-based product stored at（3±1） ℃ with MAP（75% CO2＋25% N2）.The results showed that the PVDC/CPP and PET/CPP with higher barrier properties were better than PP/CPP in bacterial counts,pH value,TVB-N value and sensory evaluation of the MAP fish-ball.The preservation effect on the MAP fish-ball decreased with the drop of their barrier properties for the three MAP materials PVDC/CPP,PET/CPP and PP/CPP,with the shelf-life of 42 days,28 days and 21 days,respectively.Thus,it was suggested that the quality and shelf life of the MAP fish-ball were well kept and extended under packaging material with higher barrier properties.

关 键 词： 包装材料 气调包装 鱼糜制品 货架期
