Abstract: Fresh-cut Dioscorea opposita Thunb.cv.Tiegun were coated with edible film composed of chitosan and sodium alginate.Every two days the weight loss rate,Vc content,titratable acid content,browning,soluble solid content,PPO activity were measured to study the preservation effect.The untreated group and chitosan single coating film group were compared.The results showed that the 1.2% chitosan single coating film and 1.2%-chitosan-0.2%-sodium-alginate composite film could effectively reduce the browning,weight loss rate and nutrient loss.The best preservation effects were achieved by compound coating film.
