Objective: To study optimum inclusion process condition for volatile oil with beta-cyclodextrin (beta-CD).
Methods: The optimum preparation condition were investigated by orthogonal design. The influence of utilization beta-CD and oil, inclusion temperature and time were studied to determin the utilization ratio of volatile oil and oil-bearing rate.
Results: The optimum preparation conditions were established as: volatile oil: beta-CD was 1:10, the inclusion temperature was 60 degrees C and inclusion time was 3h.
Conclusion: The method is convenient and can he used for mass production.
