| 中文摘要: |
| 采用超声波辅助提取黄秋葵籽油并采用GC-MS对其脂肪酸组成进行分析。通过单因素试验考察提取溶剂、原料粒度、料液比、提取温度、提取时间、超声功率对黄秋葵籽油得率的影响。在单因素试验基础上采用正交试验优化得到最佳提取工艺条件为：正己烷为提取溶剂，原料粒度40～60目,料液比1∶9,提取温度50℃,提取时间75 min,超声功率80 W。在最佳条件下，黄秋葵籽油得率为26.26%。从黄秋葵籽油中鉴定出11种脂肪酸，主要为不饱和脂肪酸，含量最高的为亚油酸，占34.06%。 |
| 英文摘要: |
| The ultrasonic-assisted extraction of Abelmoschus esculentus seed oil was studied and the fatty acid composition of Abelmoschus esculentus seed oil was analyzed by GC-MS. The effects of extraction solvent, material granularity, ratio of material to liquid, extraction temperature, extraction time and ultrasonic power on the yield of Abelmoschus esculentus seed oil were studied by single factor experiment. Then the ultrasonic-assisted extraction conditions were optimized by orthogonal experiment as follows: with n-hexane as extraction solvent, material granularity 40-60 meshes, ratio of material to liquid 1∶9, extraction temperature 50℃, extraction time 75 min, ultrasonic power 80 W. Under the optimal conditions, the yield of Abelmoschus esculentus seed oil was 26.26%,and eleven kinds of fatty acids were identified from Abelmoschus esculentus seed oil, among which the content of linoleic acid was the highest, reaching 34.06%. |
