Effect of Chitosan Coating on Preserving Character of Post-Harvest Fruit and Vegetable: A Review

Abstract

Chitosan coating as an edible substance has been applied in the preservation of fresh fruit, vegetable or their fresh-cut materials. After coating with chitosan on the surface of post-harvest fruit and vegetable, the respiration rate and weight loss rate are restrained, and higher firmness is remained. Meanwhile, the activities of protective enzymes are maintained higher level, and the cell membrane can keep relatively intact. Furthermore, chitosan coating has certain preventive effect against microbes and can reduce decay. Since the storage condition of post-harvest fruit and vegetable is improved, more nutrients are also reserved. Chitosan coating would probably have wide prospect in the preservation of post-harvest fruits and vegetables in the future.
