采用正交试验法 ,研究了β CD包合干姜挥发油的工艺。通过正交设计直观分析方法进行多因素多水平试验 ,以挥发油利用率为指标来评定工艺的优劣。结果筛选出饱和水溶液法较佳包合工艺为A3B3C2 :即 β CD与挥发油的配比为 6∶1,包合温度为 5 5℃ ,包合时间为 2h。最后用显微镜成像法和薄层层析法验证了包合物的形成 Orthogonal test was used to study the β CD inclusion process of volatile oil from Ginger. The multi-factor and multi-level test was conducted through the visual analysis method of orthogonal design, and the pros and cons of the process were evaluated by using the volatile oil utilization rate as an indicator. The results showed that the optimal inclusion process of saturated aqueous solution was A3B3C2: the ratio of βCD to volatile oil was 6:1, the inclusion temperature was 55°C, and the inclusion time was 2h. Finally, the formation of clathrates was verified by microscopic imaging and thin layer chromatography.
