Method of using cyclodextrin to embed gasified plant essential oil

Abstract

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.

Description

Technical field [0001] The invention belongs to the technical field of cyclodextrin embedding of plant essential oils, and in particular relates to a method for cyclodextrin inclusion and gasification of plant essential oils. Background technique [0002] There are currently three methods for cyclodextrin inclusion of volatile oil to form stable inclusions. The liquid-liquid embedding method has a relatively active molecular diffusion force when the host and guest are in the liquid state, which increases the collision probability of the host and the guest. Therefore, the utilization rate of the embedded object is higher, and the prepared inclusions are of high purity and quality. Good, but because it needs to maintain a liquid state, it consumes a lot of solvents; the gas-solid embedding method does not need to consume a lot of solvents, but because it is only suitable for substances that are prone to produce, it requires professional equipment with high temperature and high pres...

Problems solved by technology

The liquid-liquid embedding method has a relatively active molecular diffusion force when the host and guest are in a liquid state, which increases the probability of host-guest collision, so the utilization rate of the embedding object is high, and the prepared inclusions are of high purity and quality. Good, but it consumes a large amount of solvent because it needs to maintain a liquid state; the gas-solid embedding method does not need to consume a large amount of solvent, but because it is only applicable to the substances of Yishenghua, it needs professional equipment with high temperature and high pressure functions. Suitable for industrial production; the solid-liquid embedding method only needs to prepare the main body into a solution, relatively less water consumption, short processing time, and does not require expensive equipment. The molecular diffusion force is weak, and the chance of host-guest contact is relatively reduced, so the utilization rate of the embedding object is not high
