摘要
以小麦面筋蛋白(WG)为原料,研究各因素对以山梨醇为增塑剂所制小麦面筋蛋白膜各项性能(通透性、机械性能)影响。基于该课题研究重点,仅以面筋蛋白膜透水率为指标进行正交实验,最终得到最佳成膜条件为:谷朊粉:山梨醇为3.5:1、乙醇浓度50%、反应温度60℃、透水率0.376×10-10g·m-1·S-1·Pa-1。
The effects of many factors on properties (barrier properties, and mechanical properties)of edible films prepared with wheat gluten (WG) and plasticizer (sorbitol) were inverstigated in present paper. The optimal conditions prepared edible films only using water vapor permeability (WVP) as indicator of film properties because of the paper' emphasis were obtained. The result showed that WG/sorbitol ratio 3.5 : 1, ethanol concentration 50%, temperature 60℃, WVP 0.376 × 10^-10g·m^-1·s^-1·Pa^-1 respectively based on the orthogonal tests.
