壳聚糖-蒙脱土复合涂膜在常温下对荔枝货架期及品质的影响
Effect of Chitosan-montmorillonite Coating on Shelf Life and Quality of Litchi Fruit Under Ambient Temperature
摘要
Abstract
The weight loss,hardness,soluble solid content,vitamin C,titrated acid,pericarp browning,polyphenol oxi-dase,and peroxidase activity of litchi coated with chitosan and chitosan-montmorillonite (MMT) for 8 days at room tempera-ture was tested.Litchi stored without coating was used as control group.The weight loss of litchi coated with chitosan and chitosan-MMT coating was significantly lower than that of control group.The chitosan-MMT coating would effectively maintain the hardness of litchi and could retard the harmful changes in soluble solid content,vitamin C,titrated acid,and pericarp browning index when compared to chitosan coating and control group.The chitosan-MMT coating could effectively suppress the polyphenol oxidase and peroxidase activity of litchi.The results showed that the chitosan-MMT coating could be used to delay the aging process of litchi and extend its postharvest life.关键词
