Abstract:

The extraction of da-hong star anise oleoresin by supercritical fluid CO2 was studied. The results showed The optimum process parameters were as follows：mesh size was 1.50 mm, the pressure was 25 MPa and 55 ℃ for 2.5 h(extraction kettle of 5 L, the flow rate of CO2 was 55 L/h). In this condition, the yield was 12.83%, the extraction rate was 92.31%. In addition, the volatile components of star anise oleoresin were analyzed by GC-MS. The main components were trans-anethole(83.74%), D- Limonene, estragole, etc.
