| Abstract: |
| In order to improve the yield of sea-buckthorn seed oil, with sea-buckthorn seed as raw material, the process of ultrahigh pressure assisted extraction of sea-buckthorn seed oil was studied. The effects of solvent type, ultrahigh pressure, pressure holding time, and material-liquid ratio on the yield of sea-buckthorn seed oil were investigated through single factor experiment. Then the main factors affecting the yield of sea-buckthorn seed oil were optimized using the Box-Behnken response surface methodology. The results showed that the optimal process conditions for extracting sea-buckthorn seed oil were obtained as follows: using petroleum ether as solvent, ultrahigh pressure 458 MPa, pressure holding time 6.2 min and material-liquid ratio 1∶ 37. Under these conditions, the yield of sea-buckthorn seed oil was 15.68%. |
