| 摘 要： | 采用壳聚糖(CS)和大豆分离蛋白(SPI)为基材,制备了可降解包装膜。用红外光谱、X射线衍射和扫描电镜对复合包装膜结构进行表征。对复合包装膜的拉伸性能和透光性能进行了测试和分析。结果表明:CS和SPI之间存在一定的相互作用;当SPI质量分数为10%时,复合包装膜的拉伸性能优于纯壳聚糖膜,透光性较纯壳聚糖膜略有下降。

| Abstract: | The degradable packaging composite films made from chitosan(CS) and soy protein isolate(SPI) were developed.The structural features of CS/SPI composite films were investigated by mean of FTIR,XRD and SEM.The tensile properties and light transmission properties of the films were tested and analyzed.The results showed that certain interaction exists between CS and SPI;when the mass fraction of SPI is 10%,the packaging composite film has higher tensile properties than that of chitosan film with slightly lower light transmittance than chitosan film. |

| Keywords: | chitosan soy protein isolate tensile property light transmission |
