摘　　要：为充分利用黑水虻油脂资源,以及优化微波-超声波协同萃取提取黑水虻幼虫油脂工艺,采用单因素试验研究萃取溶剂、萃取时间、超声波功率、固液比对黑水虻油脂得率的影响。分别以油脂得率与能量转化率为指标,采用正交试验优化微波-超声波协同溶剂提取黑水虻幼虫油脂的工艺条件。结果显示:微波-超声波提取黑水虻油脂的理想溶剂为石油醚,微波功率为100 W、温度为40℃、超声功率为100 W、萃取时间为10 min;通过正交优化试验获得最佳组合工艺为提取时间25 min,固液比(g/mL)1∶25,超声功率150 W,此时油脂得率为41.43%,能量转化率为56.79%。在试验因素范围内不同工艺参数对油脂的热稳定性和官能团组成未产生明显影响;水虻幼虫油脂中脂肪酸主要是亚油酸(19.03%)、油酸(16.66%)、月桂酸(14.92%)和棕榈酸(11.9%)。The effects of four key process parameters including the type of extractant,solid-liquid ratio,extraction time and ultrasonic power on the oil and fat of black soldier fly larvae were investigated with single factor experiments to study and determine the technology of using microwave-ultrasonic synergistic extraction to extract oil from black soldier fly larvae.Taking the oil yield and energy conversion rate as indicators,orthogonal experiments were used to optimize the technological conditions for the extraction of oil from black soldier fly larvae by microwave-ultrasonic synergistic solvent.The results showed that the ideal solvent for microwave-ultrasonic extraction of black soldier fly larvae oil was petroleum ether.The condition optimized was the extraction time of 25 min,the solid-liquid ratio of 1∶25,and the ultrasonic power of 150 W.Under the condition optimized,the oil of the yield was 41.43%,and the energy conversion rate was 56.79%.However,different parameters of process had no significant effect on the thermal stability and functional group composition of the oil within the range of experimental factors.The fatty acids in the oil of black soldier fly larvae were mainly linoleic acid(19.03%),oleic acid(16.66%),lauric acid(14.92%)and palmitic acid(11.9%).
