干燥温度对谷朊粉膜性能的影响

The Influences of Drying Temperature on the Properties of Wheat Gluten Film

干燥温度是影响谷朊粉可食性膜性能的一个重要因素.本文探讨了可食性谷朊粉膜制备过程中,采用真空干燥在不同的温度下进行时对膜透光率、水溶性、拉伸强度、断裂伸长率、水蒸气透过系数等性能的影响。试验结果表明:在60℃条件下干燥,膜的综合性能最好。

Drying temperature was one of the most important factors that affect the properties of edible wheat gluten film. The influences of different drying temperature in the preparation of samples on the properties of wheat gluten film, such as： light transmitting rate, water solubility, tensile strength, elongation rate, water vapor permeability, etc, were discussed in this paper. when the drying temperature was 60℃, the experimental results showed that the film had the best properties.
