Abstract
In this experiment, effects of different transportation and packing methods on preservation of lettuce were investigated. No scab, no mechanical wounding and the same size lettuce were selected as test material.During transportation, incubator with ice gel method could remain the lower temperature and weight loss rate than other method. The lettuce were storage at(0 ±0.2) ℃ after packaged with PE cling film and modified atmosphere packaging(MAP). The weight loss rate, soluble solids content, Vc content, chlorophyll content,MDA, the PPO activity and ethylene release rate of lettuce were determined in order to compare the fresh-keeping effect of lettuce under packing methods. The results showed that MAP and PE cling film storage could effectively delay the decline of the the nutrients loss of lettuce, slow down the weight loss rate and the rise of MDA content, reduce PPO activity and delay the increase in ethylene production. After 18 d storage, the weight loss rate of PE cling film and MAP were lower than the control by 0.65 % and 0.75 %. MAP than PE cling film can better maintain the storage quality and nutrition of lettuce during the whole storage.
