中文摘要:
      目的 研究桉叶精油微胶囊的最佳包埋工艺。方法 以β-环糊精为壁材制备桉叶精油微胶囊,通过单因素和正交试验研究微胶囊包埋工艺,确定最优包埋工艺条件。结果 最佳包埋工艺中包埋温度为40 ℃,包埋时间为1.5 h,β-环糊精质量浓度为8 g/mL。在该条件下制得的微胶囊包埋率为70.33%,微胶囊收率为86.27%。缓释试验结果表明,微胶囊化可以明显降低桉叶精油的挥发速率,Avrami's 方程也可以对桉叶精油微胶囊释放过程进行较好拟合。结论 试验达到了预期目的,微胶囊化提高了精油利用率,延长了桉叶精油的使用寿命。
英文摘要:
      The work aims to study the best inclusion technology of microcapsules of eucalyptus essential oil. β-Cyclodextrin was taken as wall material for preparing microcapsules of eucalyptus essential oil. The optimal inclusion technology was determined by single factor and orthogonal test. The most appropriate conditions were: inclusion temperature 40 ℃, inclusion time 1.5 h, mass concentration of β-Cyclodextrin 8 g/mL, under which, the inclusion efficiency was 70.33% and microcapsule yield was 86.27%. The controlled release test results showed that microcapsules could greatly reduce the releasing rate of eucalyptus essential oil. The release course of microcapsules could fit well to the Avrami’s equation. The experiment has achieved its intended purpose. Microencapsulation helps improve the utilization of eucalyptus essential oil and meanwhile prolong its service life.
