摘　　要：通过单因素试验,考察β-CD与茶树精油的比值、温度、时间、超声时间对茶树精油包合率的影响,采用Box-Behnken试验设计和响应面分析优化饱和水溶液法制备茶树精油微胶囊的包合工艺,并进行包合产品储藏稳定性分析。结果显示最佳的包合条件为:β-环糊精与茶树精油比值11:1(g/g)、温度67°C、时间60 min,包合率约59.24%;且制备的茶树精油β-CD包合物在常温下保存一个月,茶树精油保留率约67%,这证实β-CD的包合作用对茶树精油有一定的保护作用,且为其应用开发提供理论基础。In this paper,single factor experiments were used to examine the influence of ratio ofβ-CD to tea tree essential oil,stirring temperature,inclusion time and ultrasonication time on microencapsulation efficiency of tea tree essential oil.The inclusion process for preparation of microcapusules of tea tree essential oil by satured water solution method using the response surface methodology with Box-Behnken experimental design was optimized,and their storage stability was investigated.The results show that the optimal inclusion conditions were as follows:the ratio ofβ-CD to tea tree essential oil was 11:1,stirring temperature 67℃,inclusion time 60 min.and the microencapsulation efficiency 59.24%;And the obtained samples were preserved at room temperature for one month,the retention rate of tea tree essential oil was about 67%,which confirmed that the inclusion effect ofβ-CD had certain protective effect on tea tree essential oil,and provides a theoretical basis for its application and development.
