Embodiment Construction

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

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

[0013] (1) Remove impurities from the bergamot and dry the bergamot 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 bergamot 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 is 20 minutes, 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 temper...

Abstract

The invention discloses a bergamot essential oil extraction method. The method includes steps: (1) decontaminating bergamots, drying until the moisture content is not higher than 10%, and grinding to 40-mesh powder for standby application; (2) adopting LED (light emitting diode) for irradiating bergamot particles, wherein illumination time is 15-25min, illumination intensity is 15-20lx, and illumination color temperature is 5500-6000K; (3) adding absolute ethyl alcohol being three times of the bergamot particles in weight, and standing for 1h at 20 DEG C to obtain a mixed solution; (4) putting the mixed solution treated at the step (3) in a microwave extractor, and performing microwave treatment for 10min under a microwave power condition of 400w; (5) extracting vapors, refrigerating collected crude products for 2h in a refrigerator at 5 DEG C, and finally centrifuging for 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 bergamot 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 l...
