Method of using cyclodextrin to embed gasified plant essential oil

The invention discloses a method of using cyclodextrin to embed gasified plant essential oil and belongs to the technical field of cyclodextrin embedding of the plant essential oil. A key to form a high-utilization-rate inclusion complex is enabling diffusion force of subjective and objective molecules to be in a highly active state, while strength of molecule diffusion force is in gas state, liquid state and solid state. On one hand, cyclodextrin cannot form a gas phase, so that molecule diffusion force of cyclodextrin in the liquid state is highest; on the other hand, volatile oil can form a gas phase when being heated, so that molecule diffusion force of the volatile oil is most active in the gas state. Therefore, a gas-liquid embedding means is utilized to increase chance of contacting between the subjective and objective molecules so as to obtain the high-utilization-rate inclusion complex. The problems of high solvent consumption of a liquid-liquid embedding method and low inclusion-complex utilization rate of a solid-liquid embedding method are solved by the gas-liquid embedding method, in other words, the gas-liquid embedding method does not need or only needs little organic solvent and does not need high-temperature high-pressure special equipment, so that the method is low in energy consumption and suitable for industrial production.
