Open publisher page 0 citations

Abstract

In the extraction with supercritical fluid, extraction of supercritical carbon dioxide is served as solvent. Its density is controlled by the alteration of pressure and temperature. It has a direct effect on the solubility. In the supercritical extraction experiment, nutmeg powder is served as the testing material. After the experiment, some relative data are set: extraction pressure 30 MPa, extraction temperature 50 ℃, pump frequency of CO_2 20 Hz, extraction time 2 h. Under the above conditions, the extraction rate can arrive at 46%.
