Abstract: This paper studied mainly the composite films made of chitosan and konjac glucomannan at different ratio of blending,and the composite films properties including transparency、water solubility、tensile strength(TS) 、elongation (E) 、watervapor permeability (WVP) and hygroscopicity.The results showed that the transparency and tensile strength of C/KG filmsin middle ratio turned less, while WVP larger. The water solubility of C/KG films went up with the increase of KG ingredientand the decrease of C ingredient. The hygroscopicity and elongation of C/KG films decreased with the increase of KGingredient and the decrease of C ingredient.

Key words: Edible film Chitosan , Konjac , Glucomannan
