ResultTemperature increasing, and above this pressure the solubility increases with temperature rises the solubility of kiwi fruit seed oil in SC-CO2 were 8.9-11.2 g·kg-1CO at pressure of 30 MPa -35 MPa and temperature of 40 ; the optimal extractive conditions are 30 MPa-35 MPa, 40 , and 2 water content of the raw material is 5%-7%.
