摘　　要：以壳聚糖和淀粉为主要成膜材料,通过调整壳聚糖和淀粉的比例及添加甘油的量,制备可食性膜。并对膜的结构性能进行了分析,实验结果表明:壳聚糖淀粉的质量比为8∶2共混,甘油的含量为0.4%,干燥温度为55℃时膜的力学性能最好,扫描电镜、X射线衍射及红外图谱结果都显示出壳聚糖淀粉两者成膜时表现出很好的相容性。Edible film with chitosan and starch as starting materials by regulating proportion of chitosan and starch and glycerol content was prepaed. The structural characteristics were analyzed. The result showed that mechanical property of the film was optimized when the mass ratio of chitosan and starch was 8∶ 2,the content of glycerine was 0. 4%,and drying temperature was 55℃. Scanning electron microscope（SEM）,x-ray diffraction analysis（XRD） and Fourier transformed infrared spectroscopy（FT-IR）results showed the good compatiblity of chitosan-starch compound films.
