摘要：In this test, cinnamaldehyde-hydroxypropyl-ȕcyclodextrin inclusion complexes were prepared by aqueous solution stirring method. The RSM is used to optimize the process conditions. The inclusion ratio and the yield of inclusion complexes were used as response values to obtain cinnamaldehyde-hydroxypropyl-ȕ-cyclodextrin inclusions. The optimal conditions for inclusion of the compound were: ratio of molecules 1:1, inclusion time 3 h, and inclusion temperature 30°C. Cinnamaldehyde and hydroxypropyl-ȕ-cyclodextrin have formed inclusions, and the inclusion rate can reach 75% with a yield of 99.0%. Therefore, the inclusion process enables the preparation of a cinnamaldehyde inclusion compound, improves its solubility, and prepares the cinnamaldehyde from a volatile oil into a solid powder formulation.
