The oil were extracted irom gardenia pomace by supercritical CO2 extraction and organic solvent extraction methods, and the extraction conditions of supercritical CO2 extraction were optimized by quad- ratic regression orthogonal experiment, and the extraction conditions of organic solvent extraction were op- timized by orthogonal experiment. The optimal extraction conditions of supercritical CO2 extraction were intially determined as follows ： extraction pressure 40 MPa, extraction temperature 55 ~C, velocity of CO2 15 kg/h. The optimal extra...
