摘要
用超声波辅助溶剂萃取辣木籽油,以出油率为评价标准,优化萃取过程的最佳工艺条件。通过4个因素的单因素试验、正交试验以及验证试验,优化出了影响辣木籽出油率的主要因素水平和最佳工艺条件。结果显示,超声波辅助溶剂萃取辣木籽油的最佳条件为:溶剂石油醚,提取次数2次,提取时间40 min,超声波频率28 kHz,液料比8∶1(V/W),在此条件下,辣木籽的平均出油率为35.85%,提取率96%,表明超声波辅助溶剂萃取法是一种可用于萃取辣木籽油的适宜方法。
Ultrasonic- aid solvent extraction of moringa seed oil was studied. Based on extraction rate evaluation,the extraction conditions were optimized through single - factor experiments with 4 factors, orthogonal experiments, and a verifying test. Results show the optimal conditions for the moringa seed oil extraction are as follows： using petroleum ether as solvent, the ratio of solvent to moringa seeds is 8：1 （V/mL： W/g）, extraction time 40 min and extracting twice with the aid of 28 kHz ultrasonic. At the conditions, the average oil yield is 35.85 % and the extraction rate is 96%. It is demonstrated that ultrasonic - aid solvent extraction is suitable for moringa seed oil extraction.
