摘  要:
以壳聚糖为主要成膜材料,添加适量的柠檬草精油,制备可食性复合膜,测定了柠檬草精油对膜的理化性质和抗菌性能的影响。红外光谱谱图说明柠檬草精油与壳聚糖基质间发生相互作用。扫描电镜结果表明两者共混成膜时柠檬草精油均匀分散。添加柠檬草精油,降低了复合膜的透明度,却能有效提高其抗拉强度、水蒸气阻隔性能和抗菌活性。

摘  要:
Chitosan composite film was prepared with chitosan and lemongrass(Cymbopogon citrates)essential oil. Physiochemical properties and antibacterial abilities were tested. FTIR results showed that there were interactions between lemongrass essential oil and chitosan functional groups. SEM images revealed that lemongrass essential oil homodispersed in chitosan matrix. The results showed that transparency of composite films decreased and tensile strength,water vapor barrier properties and antibacterial abilities were improved
