摘要: 为了提高切割生菜的贮藏保鲜品质,研究了贮藏温度和包装材料及方式对鲜切生菜品质的影响。结果表明:在一定范围内,贮藏温度越低越有利于保持切割生菜的品质。经1%NaCl+l%VC处理的切割生菜在5℃下的保存期只有 6d,而在0℃下保存期可达到 18d,并且显著抑制了多酚氧化酶(PPO)活性的上升和总酚含量的下降。采用真空包装或MA包装具有较好的防褐保鲜作用。经 1%NaCI+l%VC处理后真空包装或 MA包装的切割生菜在0℃下的保存期可达到21d。真空包装显著抑制了(PPO)活性的上升和总酚含量的下降。

Abstract: It was shown in this study that the quality of shredded lettuce was enhanced by storing at 0℃ and by vacuumize-package or MA-packaging.The shredded lettuce(pretreated with1%NaCl+l%VC)could be stored for 6 days at 5℃ and for 18 daysat 0℃.The shredded lettuce vacuumize-packaged could be stored for for 21days at 0℃.Increasing in polyphenoloxi dase activityand decreasing in polyphenol level was inhibited by low temperature or/and vacuumize-package.

Key words: packaging, storage, shredded lettuce, polyphenoloxidase
