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
