中文摘要:

      目的 确定玉米淀粉/卡拉胶/甘油复合膜的最佳成膜工艺。方法 以玉米淀粉为基材, 与卡拉胶和甘油共混, 通过流延法制备复合膜, 以薄膜的机械性能为评价指标, 通过单因素实验及正交实验来确定最佳成膜工艺。结果 正交实验结果表明当玉米淀粉添加量为3%、卡拉胶添加量为30%、甘油添加量为25%时, 玉米淀粉薄膜的机械性能最佳。结论 本研究确定了玉米淀粉、卡拉胶和甘油的最佳成膜配比, 为玉米淀粉膜的生产及应用提供理论基础。

英文摘要:

      Objective To determine the optimal film forming process of corn starch/carrageenan/glycerol composite film. Methods Corn starch was used as substrate, blended with carrageenan and glycerol, and the composite film was prepared by tape casting. Taking the mechanical properties of the film as the evaluation index, the optimal film forming process was determined by single factor experiment and orthogonal experiment. Results The orthogonal experimental results showed that the mechanical properties of corn starch film were the best when the addition of corn starch was 3%, carrageenan was 30% and glycerol was 25%. Conclusion This study determines the optimal film forming ratio of corn starch, catageenan and glycerol, providing the theoretical basis for the production and application of corn starch film.
