Preparation method of lavender essential oil emulsion

The invention relates to a preparation method of lavender essential oil oil-in-water emulsion, the preparation method comprises the following steps: deionized water, gelatin, glycerol and an emulsifier into xanthan gum are sequentially added, and mixed to obtain a continuous phase; lavender essential oil is used as a dispersion phase; the essential oil emulsifying film is used as an emulsifying medium, a compressed gas tank is used for providing pressure, the dispersion phase is pressed into a film tube of the essential oil emulsifying film to form jet flow under the transmembrane pressure difference, and the dispersion phase leaves the surface of the film tube and enters the continuous phase under the shearing force action of the continuous phase, so that the lavender essential oil oil-in-water emulsion is formed. The nanoscale lavender essential oil emulsion is prepared with low energy consumption and high flux, the stability and physiological absorbance of the emulsion are effectively improved, the storage
