| 以黑水虻幼虫为原料，分别采用压榨法、浸出法以及亚临界丁烷萃取法提取黑水虻油，采用单因素实验和正交实验优化了压榨和浸出制油的工艺条件，并比较3种方法的提油率、黑水虻油的理化性质和脂肪酸组成。结果表明：压榨法提取黑水虻油的最佳工艺参数为蒸炒温度140 ℃、蒸炒时间30 min、黑水虻幼虫粉水分含量5%，在此条件下提油率为54.10%；浸出法提取黑水虻油的最佳工艺参数为浸出温度60 ℃、浸出时间5 h、料液比1∶ 5，在此条件下提油率为78.95%。3种提取方法中，浸出法的提油率最高，亚临界丁烷萃取法的次之；亚临界丁烷萃取法所得的黑水虻油的酸值和过氧化值最低，浸出法所得的黑水虻油的水分含量最低，压榨法的水分含量最高；3种提取方法的黑水虻油脂肪酸组成变化不大，黑水虻油饱和脂肪酸中月桂酸含量最高，为16%~20%，不饱和脂肪酸中亚油酸和油酸含量较高，分别约为22%和20%。 |
| 英文摘要: |
| The black soldier fly (Hermetia illucens) larvae oils were respectively extracted from black soldier fly larvae by pressing method, leaching method and subcritical butane extraction method,and the single factor experiment and orthogonal experiment were conducted to optimize pressing method and leaching method,then the oil extraction rates, physicochemical properties and fatty acid compositions of black soldier fly larvae oils obtained by the three methods were compared. The results showed that the optimal pressing extraction conditions of black soldier fly larvae oil were obtained as follows: cooking temperature 140 ℃, cooking time 30 min and water content of larvae powder 5%. An extraction rate of 5410% of black soldier fly larvae oil was achieved under the optimal pressing extraction conditions. The optimal leaching extraction parameters of black soldier fly larvae oil were obtained as follows: leaching temperature 60 ℃,leaching time 5 h, solid -liquid ratio 1∶ 5. The extraction rate of black soldier fly larvae oil was 78.95% under the optimal leaching extraction conditions. The leaching extraction of black soldier fly larvae oil showed the highest oil extraction rate, followed by subcritical butane extraction method. The acid value and peroxide value of subcritical butane extracted oil was the lowest.The moisture content in the oil obtained by leaching method was the lowest, while it was the highest in pressed black soldier fly larvae oil. Extraction method had no effect on the fatty acid composition of black soldier fly larvae oil,and the oil had the highest content of lauric acid in saturated fatty acids, reaching 16%-20%, and high contents of linoleic acid and oleic acid in unsaturated fatty acids, reaching about 22% and 20% respectively. |
