Objective To optimize the preparation process of Pogostemon cablin volatile oil β-cyclodextrin inclusion. Methods On the basis of single factor investigation, G1-entropy weight method combined with central composite design and response surface method was used. Shear speed, shear time, and the ratio of β-cyclodextrin to volatile oil were investigated with the comprehensive score of yield rate and inclusion rate as evaluation indexes. The interaction of various factors was analyzed by Design-Expert 8.0.6.1 software, and the optimized preparation process was investigated. Results The optimal inclusion process of high speed shear inclusion process was as follows:the ratio of β-cyclodextrin to volatile oil was 8:1, the shear time was 3 min, the shear speed was 4200 r/min, and the ratio of β-cyclodextrin to water was 1:7. Conclusion The optimized inclusion process of Pogostemon cablin volatile oil β-cyclodextrin inclusion is optimized, and can provide guidance for the development and production of related products in the future.
