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%。
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 at121 ℃ 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%.
