Abstract
The leaves of lettuce were stored at -2C, -1C, 0C, 1C, 2C under packaged with corrugated board box or non-packaged condition. Chilling injury occurred in the non-packaged lettuce stored at -1C after one day, but the lettuce packaged with the box did not show the injury even after 2-3 days. The temperature of lettuce packaged with box was 1-5C higher than that of the air in storage chamber. A weight loss and decreasing of moisture contents were higher in the non-packaged lettuce than in the packaged, and the degree of loss was more severer at 0C, 1C, 2C storage than at -1C and -2C. Chilling injury or freezing injury were not observed in the lettuce stored at 0C in any treatments. In case that the lettuce was stored at the same temperature, electrolyte leakage tended to increase as storage period was extended, showing higher in non-packaged lettuce than that of packaged. The highest value of electrolyte leakage was observed from the non-packaged lettuce stored at -2C. There was no chilling injury in the lettuce packaged in the box stored at 0C. It maintained freshness and high quality even after one week of storage.
