可食性淀粉膜制备材料与工艺的研究

Studies on Materials and Processing Conditions of Edible Starch Film

本试验对可食性淀粉膜的制备材料选择、工艺条件及膜的应用进行了研究。结果表明：以玉米原淀粉为成膜主体，配以甘油（增塑剂）和羧甲基纤维素钠（增强剂），在８０～８５℃烘干１ｈ左右，即可得到比较理想的可食性淀粉膜。应用实验表明，这种膜具有良好的阻湿性与阻气性。

This paper is mainly concerned about the materials, processing conditions and the application of the edible starch film. Through a series experiments, maize starch, glycerin and CMC-Na were determined as the proper materials. The drying temperature was 80-85℃, the drying time was about one hour. From the applied experiment the films were proved to be good barrier of moisture and air.
