摘要： 采用响应面法对马铃薯淀粉基复合膜的制备工艺进行优化。选取淀粉含量、糊化温度、硬脂酸含量、软脂酸含量、纳米SiO2含量、溶液pH值为单因素，对膜的透光率、油脂渗透系数、拉伸强度和延展性、水蒸气透过率、水溶性进行测定。在单因素实验的基础上，采用响应面法探讨最佳工艺参数。结果表明，马铃薯淀粉含量314%，软脂酸含量0189%，硬脂酸含量0203%，纳米SiO2含量0301%，糊化温度90℃，pH为6时，所制得膜的综合性能最佳。

Abstract: Based on the response surface method， the preparation process of potato starch\|based composite films was optimized. Starch content， gelatinization temperature， stearic acid content， palmitic acid content， nano\|SiO2 content， pH value were taken as single factors， respectively， to determine their influence on the transmittance， oil permeation coefficient， tensile strength， ductility， water vapor permeability and water solubility of the produced films. On the basis of single factor experiments， the optimal process parameters were explored by response surface method. It was shown that the production parameters were optimized as follows: 314% of potato starch content， 0189% of palmitic acid， 0203% of stearic acid， 0301% of nano\|SiO2， pH value of 6， and gelatinization temperature of 90℃. Under this condition， the properties of the produced films were the best.
