中文摘要:
      目的 以玉米磷酸酯双淀粉为基材, 甘油为增塑剂, 制备可食性包装膜。方法 通过改变玉米磷酸酯双淀粉添加量, 测试可食性包装膜的厚度、 定量、 力学性能、 透湿性和透CO2性等指标, 从而确定最佳配比。结果 实验发现, 随着玉米磷酸酯双淀粉添加量的增大, 可食性包装膜的厚度和定量增大, 拉伸强度、 拉伸率和透湿性先增大后减小, 透 CO2性下降。结论 在 80 ℃条件下搅拌 40 min、烘干温度为60 ℃时, 淀粉的质量分数为7.5%、 甘油的体积分数为5%的薄膜综合性能较好。
英文摘要:
      To prepare edible film using corn distarch phosphate as the base material and glycerol as the plasticizer. By changing the corn distarch phosphate content, the performance indexes of the edible film such as thickness quantity, mechanical property, moisture permeability, and CO2 permeability were tested to determine the best proportion. It was found that along with the increase of addition amount of corn distarch phosphate, the thickness and quantity of the edible film increased, while the tensile strength, stretch rate and water vapour transmission rate first increased and then decreased, and the CO2 permeability decreased. The experimental results showed that: under the condition of 80 ℃ mixing for 40 min, a drying temperature of 60 ℃ , a starch mass ratio of 7.5% , and a glycerol volume ratio of 5% , the film with the best comprehensive performance was obtained.
