| 中文摘要: |
| 为了提高玉米油精炼的附加值，并实现硅藻土的可循环利用，以玉米油精炼副产物含蜡脂的硅藻土为原料，采用超声辅助水剂法提取玉米蜡脂，考察了不同提取条件对玉米蜡脂提取率的影响，并通过响应面法优化玉米蜡脂提取的工艺条件。结果表明：超声辅助水剂法提取玉米蜡脂的最佳工艺条件为超声功率480 W、超声时间4 h、提取温度95 ℃、料液比1∶ 3，在此条件下玉米蜡脂提取率为（59.46±0.91）%。综上，超声辅助水剂法可以有效提取硅藻土中的玉米蜡脂。 |

| In order to improve the corn oil refining added value and realize the recyclable use of diatomaceous earth, diatomaceous earth containing wax lipid, a by-product of corn oil refining, was used as raw material to extract corn wax lipid by ultrasonic-assisted aqueous method, the effects of different extraction conditions on the extraction rate of corn wax lipid were investigated, and the process conditions for the extraction of corn wax lipid were optimized by response surface methodology. The results showed that the optimal extraction conditions were as follows: ultrasonic power 480 W, ultrasonic time 4 h, extraction temperature 95 ℃, and material-liquid ratio 1∶ 3. Under these conditions, the extraction rate of corn wax lipid was （59.46±0.91）%. In conclusion, the ultrasonic-assisted aqueous method can effectively extract corn wax lipid from diatomaceous earth. |
