摘要: 利用玻璃板延流法制取葛根淀粉-壳聚糖复合膜,运用流变仪、质构仪等仪器测定葛根淀粉、壳聚糖、甘 油不同配比下复合膜的成膜特性,并通过响应面法分析和优化3种物料的配比。结果表明,以抗拉强度、延伸率、 水蒸气透过率和透明度为评价指标,通过Design-Expert软件分析得到在葛根淀粉质量分数1.5%,壳聚糖质量分数 1.29%,甘油质量分数24.27%时,葛根淀粉-壳聚糖复合膜的性能最好。

Abstract: To extend the application of chitosan-kudzu starch, we developed the film by casting and studied the properties of films with different composition by Texture Analyzer, Rheometer etc. The Response Surface Method (RSM) was used to analyze and optimize the composite concentration. Besides, the effects of components of the mixture on the tensile strength, elongation of rupture, water vapor permeability (WVP) and opacity of the films were studied. According to the models generated by and Design-expert software, the edible films display the best properties with the composition of 1.5% kudzu starch, 1.29% chitosan and 24.27% glycerol. Our results provide statistical support for industrial production of chitosan-kudzu starch films.
