以广藿香油为芯材,壳聚糖（CTS）、壳聚糖季铵盐（HACC）、阿拉伯胶（GA）为壁材,采用复凝聚法制备了广藿香油微胶囊。采用扫描电子显微镜（SEM）、激光粒度仪、傅立叶红外光谱（FT-IR）对微胶囊进行表征,并对其热稳定性、缓释性、抗菌性进行了研究。结果表明,微胶囊球形规则、分散性好,湿囊的平均粒径为10.8μm,微胶囊化提高了广藿香油的热稳定性。在相对湿度24%,37℃密封环境中储藏20 d,微胶囊对金黄色葡萄球菌、大肠杆菌的最小杀菌浓度分别为1.25 mg/mL和2.5 mg/mL。
The patchouli oil microcapsules were prepared by complex coacervation method with chitosan,quaternary ammonium salt of chitosanand gum arabic as the wall materials and patchouli oil as the core materials.The structure and properties of the microcapsules were characterized by scanning electron microscopy（SEM）,laser particle diameter analyzer,and Fourier transform infrared spectrometry（FT-IR）.The thermal stability,controlled release properties and antibacterial properties of the microcapsules were evaluated.The results show that the microcapsules with average size 10.8 μm are spherical and dispersed.The thermal stability of patchouli oil is improved by microencapsulation.After being stored 20 days in the relative humidity of 24%,temperature of 37 ℃ storage sealed environment,the minimum bactericidal concentrations of microcapsules for Staphylococcus aureus and Escherichia coli are 1.25 mg/mL,2.5 mg/mL,respectively.
