| description | The invention provides a dried tangerine peel oil extracting method. According to the method, dried tangerine peels are ground to 80-100 meshes by a liquid nitrogen grinder, a dried tangerine peel raw material is obtained, and the moisture content is controlled to range from 15% to 25%; the dried tangerine peel raw material is extracted by the aid of propane and butane mixed alkane at the temperature of 25-35 DEG C and under the pressure of 0.2-0.5 MPa for 30-40 min; the extracted dried tangerine peel raw material is subjected to extraction by the aid of supercritical CO2 again at the temperature of 50-65 DEG C and under the pressure of 10-20 MPa for 50-70 min, and dried tangerine peel oil is obtained through resolution and separation. The method is used for extracting the dried tangerine peel oil, the extraction ratio is higher than 6.4%, the dried tangerine peel oil is rich in functional components, contains more than 62% of polymethoxyflavonoids, has the bright yellow and transparent color, has the pure and strong fragrance and is free of the irritating odor and the biting taste, and the retention degree of the original flavor of the dried tangerine peels is high. |
