| 中文摘要: |
| 为提高沙棘籽油得率，以沙棘籽为原料，研究了超高压辅助提取沙棘籽油的工艺。通过单因素实验考察了溶剂类型、超高压压力、保压时间、料液比对沙棘籽油得率的影响，在此基础上采用Box-Behnken响应面法对影响沙棘籽油得率的主要因素进行优化。结果表明：超高压辅助提取沙棘籽油最优工艺条件为以石油醚为溶剂、超高压压力458 MPa、保压时间6.2 min、料液比1∶ 37，在此条件下沙棘籽油得率为15.68%。 |
| 英文摘要: |
| 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%. |
