| 中文摘要: |
| 以辣木籽为原料，在单因素实验的基础上通过正交实验优化微波辅助提取辣木籽油的工艺条件，并将最佳条件下的辣木籽油得率及其品质与超声波辅助法、溶剂浸出法的进行对比分析。结果表明：微波辅助提取辣木籽油的最佳工艺条件为微波功率密度5 W/g、微波辐射时间6 min、提取温度50 ℃、提取时间30 min，在此条件下辣木籽油得率为36.45%；与超声波辅助法和溶剂浸出法相比，微波辅助法得率最高，所得辣木籽油的碘值最大，植物甾醇、多酚、黄酮含量最多，过氧化值最低，是一种应用前景广阔的辣木籽油提取方法。 |
| 英文摘要: |
| With Moringa oleifera seed as raw material, based on single factor experiment, the microwave-assisted extraction conditions of Moringa oleifera seed oil were optimized by orthogonal experiment. The yield and quality of Moringa oleifera seed oil under the optimal conditions were compared with those by ultrasound-assisted extraction and solvent extraction. The results showed that the optimal extraction conditions were obtained as follows: microwave power density 5 W/g, microwave irradiation time 6 min, extraction temperature 50 ℃ and extraction time 30 min. Under these conditions, the yield of Moringa oleifera seed oil was 36.45%. Compared with ultrasound-assisted extraction and solvent extraction, Moringa oleifera seed oil extracted by microwave-assisted method had the highest iodine value, the highest contents of phytosterols, polyphenols and flavonoids, and the lowest peroxide value, which showed that microwave-assisted extraction had a promising application prospect. |
