| 中文摘要: |
| 旨在促进小米糠资源利用，采用亚临界低温萃取技术提取小米糠油，通过单因素试验考察了萃取时间、萃取温度、料液比对小米糠提油率的影响，并在此基础上以小米糠提油率为指标，运用响应面试验对亚临界低温萃取小米糠油的工艺条件进行优化。结果表明：亚临界低温萃取小米糠油的最佳工艺条件为萃取时间25 min、萃取温度35 ℃、料液比1∶ 4，在此条件下小米糠的提油率为95.3%。综上，该工艺可用于小米糠油的有效提取。 |

| Aiming to promote the utilization of millet bran resources, the millet bran oil was extracted by subcritical low-temperature extraction technology. Single factor experiments were conducted to investigate the effects of extraction time, extraction temperature, and solid-liquid ratio on the extraction rate of millet bran oil. Based on this, with the oil extraction rate of millet bran as an index, the parameters of subcritical low-temperature extraction of millet bran oil were optimized using response surface methodology. The results showed that the optimal process parameters for extracting oil from millet bran by subcritical low-temperature extraction were as follows: extraction time 25 min, extraction temperature 35 ℃ and solid-liquid ratio 1∶ 4. Under these conditions, the oil extraction rate of millet bran was 95.3%. Overall, the process can be effectively used for the extraction of millet bran oil. |
