摘　　要：以小白杏仁为原料,从5种有机溶剂中选取一种作为萃取试剂,对杏仁油的超声波辅助提取工艺进行了研究,并与溶剂浸提法进行了比较。选取超声波处理时间、超声波功率、料液比、提取温度等4个单因素进行试验。在单因素试验的基础上,采用4因素3水平L9(34)的正交设计方案,对杏仁油的提取条件进行优化。结果表明,选用乙酸乙酯作为萃取溶剂,最佳工艺参数为超声波处理时间35 m in,超声波功率105 W,料液比1∶21(g∶mL),温度40℃。在最佳工艺条件下,杏仁油提取率可达49.35%,与溶剂浸提法相比,提取率接近。One extraction solvent was chosen from five organic solvents to extract almond oil from little white almond seed.Single factor experiments,to identify suitable ultrasonic treatment time,ultrasonic power,ratio of solid to liquid,extraction temperature,and orthogonal experiment,with three level of four factors L9（34） based on the results of single factor experiments,were carried out to research the almond oil extraction technology with ultrasonic-aided method and solvent extraction method.The results indicated the optional conditions were as follows：ultrasonic period：35 min,ultrasonic power：105 W,ratio of sold to liquid：1∶21 and extraction temperature：40 ℃,and the extracting rate was 49.35%,close to the extraction rate of solvent extraction method,with ethyl acetate as extractive solvent.
