Embodiment Construction

[0011] The technical solution of the present invention will be described in detail below.

[0012] A method for extracting sage essential oil, comprising the steps of:

[0013] (1) Remove impurities from sage and dry the sage slices until the water content does not exceed 10%, and crush them to 40 mesh for later use.

[0014] (2) Use LED light to irradiate sage grains: specifically, the illumination time of 15-25min is adopted, the illumination intensity is 15-20lx, and the color temperature of illumination is 5500-6000K; as an embodiment of the present invention, the LED light irradiation time 20min, the light intensity is 20lx, and the light color temperature is 5500K. Certainly, as another embodiment of the present invention, the LED light irradiation time is 25 minutes, the light intensity is 15lx, and the light color temperature is 6000K; or, the LED light light irradiation time is 15min, the light intensity is 20lx, and the light color temperature is 5800K The adopting...

Abstract

The invention discloses a sage essential oil extraction method. The method comprises the following steps of: (1) removing impurities from sage, then drying the sage until the moisture does not exceed 10% of sage pieces and grinding the sage into 40-mesh grains for later use; (2) adopting LED light to irradiate the sage grains, wherein the illumination time is 15-25 minutes, the illumination intensity is 15-20lx, and the color temperature of illumination is 5500-6000K; (3) adding absolute ethyl alcohol with weight being 3 times that of the sage grains and standing at 20 DEG C for one hour, thus obtaining a mixed solution; (4) putting the mixed solution after treatment in the step (3) in a microwave extraction apparatus and carrying out microwave treatment for 10 minutes under the condition that the microwave power is 400w; and (5) then carrying out water vapor extraction, refrigerating a collected crude product in a refrigerator at 5 DEG C for two hours and finally carrying out centrifugation operation to carry out oil-water separation.

Description

technical field [0001] The invention relates to the technical field of extracting essential oil from plants, in particular to a method for extracting sage essential oil. Background technique [0002] With the continuous development of economy and society and the continuous improvement of people's living standards, the demand for plant essential oils is increasing. Essential oils are a general term for a class of oily liquids that are volatile, have a strong fragrance and smell, and can be distilled with water vapor. Essential oils have active ingredients and have a wide range of applications, such as eliminating phlegm and relieving cough, dispelling wind and invigorating the stomach, repelling insects, anti-wrinkle maintenance, etc. The essence of the most popular water therapy (SPA) is natural plant essential oils. For the extraction of essential oils, the current commonly used methods are steam distillation and solvent extraction, but there are disadvantages such as low y...
