| 摘 要： | 采用不同质量浓度壳聚糖（0.5％、1.0％、2.0％）分别添加0.5％淀粉、1.0％氯化钙（CaC12）和1.0％抗坏血酸（AsA）作为涂膜剂,在（4±0.5）℃保存条件下对鲜切莲藕进行涂膜处理,测定鲜切莲藕贮藏过程中失重率和腐烂率、总糖含量、维生素C、褐变强度（BD）、多酚氧化酶（PPO）活性等的变化.结果表明：壳聚糖涂膜处理可有效降低鲜切莲藕的水分、维生素C等成分的损失,延缓鲜切莲藕褐变的发生,从而延长鲜切莲藕的货架期,且2.0％壳聚耱涂膜处理对鲜切莲藕具有良好的保鲜效果.

| Abstract: | The effects of edible complex ehitosan coating on the prevention and physiological changes were studied. Fresh-cut Lotus roots were soaked in the solution of 0.5% , 1.0 % and 2.0% of chitosan with 0.5%of starch, 1.0% of calcium chloride and 1.0% of ascorbic acid to form a coating on the surface at （4±0.5）℃. The loss rate of water and vitamin C in Lotus roots was decreased by chitosan coating. The increasing of PPO and BD was inhibited obviously by chitosan coating. The shelf life of fresh-cut Lotus roots could be extended by the coating and the best effect could be achieved by 2.0% of chitosan . |
