Effect of Chitosan Coating on the Quality of Fresh-cut Pumpkin(Cucurbita Moschata) during Storage
摘要
Abstract
Fresh "MiBen" pumpkins were subjected to coating with chitosan at different concentrations (0.5%, 1.0%, 1.5%)and subsequent storage at 4 ℃ in order to examine the fresh-keeping effect of chitosan coating on fresh-cut pumpkin. During the storage, changes in polysaccharose, carotenoid and total phenol contents, ethylene production, weight loss rate, firmness and the activity of PAL and POD of fresh-cut pumpkin were measured. Results showed that chitosan coating could delay the reductions of firmness, polysaccharose, carotenoid and total phenol contents, and also could delay the increase of ethylene production, obviously enhance PAL and POD activities, reduce weight loss rate, and substantially extend the shelf life of fresh-cut pumpkin, especially at a concentration of 1.0%.关键词
