| 中文摘要: |
| 研究了溶剂浸提法提取黄秋葵籽油的最佳工艺条件，并采用GC-MS分析其脂肪酸组成。通过单因素试验重点探讨浸提溶剂、料液比、浸提温度、浸提时间对黄秋葵籽出油率的影响，并采用正交试验确定最佳浸提工艺条件。结果表明，以石油醚(沸程60～90℃)作为浸提溶剂提取黄秋葵籽油的最佳工艺条件为：料液比（g/mL）1∶10，浸提温度60℃，浸提时间5 h；在最佳工艺条件下，黄秋葵籽出油率为16.22%；黄秋葵籽油脂肪酸组成主要为亚油酸(41.13%)、棕榈酸(37.27%)和油酸(17.19%)。 |
| 英文摘要: |
| The optimal conditions of solvent extraction of okra seed oil were studied, and the fatty acid composition of okra seed oil was analyzed by GC-MS. Effects of extraction solvent, solid-liquid ratio, extraction temperature and extraction time on the oil yield were discussed by single factor experiment. The optimal extraction conditions were determined by orthogonal experiment as follows：petroleum ether (boiling range 60-90℃) as extraction solvent, solid-liquid ratio (g/mL) 1∶10, extraction temperature 60℃, extraction time 5 h. Under the optimal extraction conditions, the okra seed oil yield was 16.22%. The main fatty acid compositions were linoleic acid (41.13%), palmitic acid (37.27%) and oleic acid (17.19%). |
