Embodiment 1

[0038]The dispersed phase is lavender essential oil, and the selected emulsifiers are Span-60 and Tween-80 (Span-60:Tween-80=0.8:1), and deionized water, gelatin, glycerin and emulsifiers are added to Xanthan in turn In the glue, use a stirrer to continuously stir at 700rpm rotating speed for 30 minutes to obtain the continuous phase, and the component volume ratio of the continuous phase is xanthan gum: gelatin: emulsifier: glycerin: deionized water=20:4:3.5:12:55 . The emulsification medium adopts a 7-channel essential oil emulsification membrane with a pore size of 20nm, which is formed by coating hydrophilic nano-titanium dioxide on the surface of a composite membrane carrier made of alumina and zirconia and sintering at a high temperature again. Among them, the 7-channel pore tubular membrane is provided with 1 large-pore channel and 6 small-pore channels along the axial direction. arranged. The wall thickness between the circular channel of the outermost small hole and...

Embodiment 2

[0040] The dispersed phase is lavender essential oil, the selected emulsifier is Tween-80, deionized water, gelatin, glycerin and emulsifier are added to the xanthan gum in turn under stirring, and the continuous phase is obtained by stirring continuously at 500 rpm for 40 minutes using a stirrer , The component volume ratio of the continuous phase is xanthan gum: gelatin: emulsifier: glycerin: deionized water=30:6:2.5:10:45. The emulsification medium adopts a 13-channel essential oil emulsification membrane with a pore size of 50nm, which is coated with hydrophilic nano-titanium dioxide on the surface of a composite membrane carrier made of alumina and silicon carbide and then sintered at a high temperature. Among them, the 13-channel pore tubular membrane is provided with 1 large-pore channel and 12 small-pore channels along the axial direction. arranged. The wall thickness between the circular channel of the outermost small hole and the outer surface of the membrane is 3.5...

Embodiment 3

[0042] Dispersed phase is lavender essential oil, select emulsifier to be Tween-80 and sodium dodecylbenzenesulfonate (Tween-80:sodium dodecylbenzenesulfonate=0.85:1), deionized water, gelatin, Glycerin and emulsifier are added in the xanthan gum successively under stirring, use agitator to stir continuously under 1000rpm rotating speed for 20 minutes and obtain continuous phase, the component concentration ratio of continuous phase is xanthan gum: gelatin: emulsifier: glycerol: deionized Water = 40:9.5:1.5:12:30. The emulsification medium adopts a 19-channel essential oil emulsification membrane with a pore size of 200nm, which is coated with hydrophilic nano-titanium dioxide on the surface of a composite membrane carrier made of alumina and silicon carbide and then sintered at a high temperature. Among them, the 19-channel pore tubular membrane is provided with 1 large-pore channel and 18 small-pore channels along the axial direction. arranged. A compressed air tank was us...

Abstract

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 period of the essential oil is prolonged, and the method has the advantages of being simple in process, convenient to operate, small in emulsion particle size, good in dispersity and the like, and is an efficient method for preparing the lavender essential oil emulsion. The method is suitable for large-scale industrial preparation of the lavender essential oil emulsion.

Description

technical field [0001] The invention belongs to the technical field of emulsion preparation, in particular to a preparation method of lavender essential oil emulsion. Background technique [0002] In recent years, plant essential oils have gained commercial popularity for their health effects and antiseptic and antiviral properties. Essential oils contain several major classes of aromatic and aliphatic compounds, such as terpenes and terpenoids. Lavender essential oil is the most valuable substance isolated from lavender. Many studies have shown that lavender essential oil has many potential health benefits, such as analgesic, antibacterial, anti-stress, anti-anxiety, anti-fatigue, anti-dysphoria, anti-depressant and anti-inflammatory effects. However, lavender essential oil is not easy to preserve, and its disadvantage is that it is volatile, and light, heat or air can easily cause oxidative deterioration of the essential oil. In addition, direct use of essential oils ca...
