| 中文摘要: |
| 以小米糠为原料，乙醇为提取剂，采用醇法提取小米糠油，并对小米糠粉的前处理方式、乙醇体积分数、浸提时间、料液比、浸提温度5个因素对小米糠提油率的影响进行了研究和优化，得到的最佳条件为烤箱121?℃焙烤15 min、乙醇体积分数95%、料液比1∶?5.84、浸提时间2.84 h、浸提温度63.4?℃，该条件下的小米糠提油率为88.65%。 |
| 英文摘要: |
| With millet bran as raw material, and ethanol as extract, millet bran oil was extracted by alcoholic method. The effects of pretreatment of millet bran powder, ethanol volume fraction, extraction time, solid-liquid ratio and extraction temperature on the extraction rate of millet bran oil were studied and optimized. The results showed that the optimal conditions were obtained as follows: baking in the oven at 121?℃ for 15 min of millet bran powder, ethanol volume fraction 95%, extraction time 2.84 h, solid-liquid ratio 1∶?5.84 and extraction temperature 63.4?℃. Under the optimal conditions, the extraction rate of millet bran oil reached 88.65%. |
