Abstract
The invention relates to an extracting method for mint essential oil. The extracting method comprises the following steps that firstly, a carrying agent accounting for 0.2-0.4% of fresh mint leaves by weight is sprayed into the fresh mint leaves, then the fresh mint leaves are added into an extraction kettle, and continuous circular extraction is carried out with supercritical carbon dioxide fluid, wherein the carrying agent is prepared from, by mass, 50-55 parts of ethyl alcohol, 3-5 parts of acetone and 0.1-0.3 part of normal hexane; secondly, carbon dioxide fluid remaining after extraction enters a separator to be separated, extraction is carried out for 1.5-2.5 h, extract matter is discharged from the bottom of the separator, standing is carried out, and the mint essential oil is obtained through oil-water separation, wherein the flow rate of the carbon dioxide fluid is 10-13 kg/h, the pressure of the separator is 6-7 MPa, and the temperature of the separator is 40-45 DEG C. The mint essential oil obtained through extraction with the method is high in purity, and the aroma can be effectively preserved.
