Study on the edible composite films of gellan gum and agar
摘要
Abstract
The gellan and agar were used as raw materials to prepare a new edible composite film through the method of blending. The optimal formula was determined through single factor and response surface analysis with index of tensile strength and water vapor transmission ratio. The result showed that the optimal formula was gellan content 1.69% ,agar content 2.60% ,the ratio of gellan in the blending solution 55.25% ,glycerol content 0.24% on the drying temperature of 55℃. The prepared edible film had tensile strength of 72.09MPa and water vapor transmission ratio of 0.58×10^10g/Pa·s·m2. This suggestd that the composite film was a very promising film for internal packaging in food industry with safe ,environmental friendly, and biodegradable properties.关键词
