Abstract:

The aim of this study was to investigate the effects of high oxygen modified atmosphere packaging on the quality of fresh-cut lettuce during storage. The lettuce slices were packaged in boxes filled with 60% O2 + 20% CO2 + 20% N2 and 100% O2 at 4 ℃ for 14 days, in contrast to that of air treatment. The results showed that the qualities of fresh-cut lettuce were significantly affected by high oxygen modified atmosphere packaging. Packaging with 60% O2 + 20% CO2 + 20% N2 and 100% O2 inhibited the loss of weight, formation of cellulose and the loss of vitamin C as well as chlorophyll. In addtion, the qualities of fresh-cut lettuce were kept better under 100% O2.

Key words: fresh-cut lettuce, high oxygen modified atmosphere packaging, quality, change
