Abstract

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.

Description

technical field [0001] The invention relates to an extraction process of tangerine peel oil, in particular to a raw tangerine peel oil with rich functional components, high content of polymethoxy flavonoids, bright yellow color, pure and strong aroma, no irritating smell, and no pungent taste. There is a method for extracting tangerine peel oil with high flavor retention. Background technique [0002] Tangerine peel is the ripe dry peel of Rutaceae citrus tangerine and its variants. Tangerine peel has the functions of regulating qi and invigorating the spleen, appetizing and eliminating indigestion, drying dampness and reducing phlegm, lowering blood pressure and blood fat, and has significant health care value. It has a long history of medicinal use and is deeply loved by consumers at home and abroad. Chenpi oil is the main functional component of tangerine peel. Studies have shown that tangerine peel oil mainly contains volatile components such as terpenes and flavonoids ...
