摘　　要：采用超声辅助乙醇对桑葚籽油(MSO)进行脱酸处理,以脱酸率为评价指标,在单因素试验的基础上通过正交试验优化脱酸工艺,并与碱炼脱酸对比研究脱酸效果。结果表明:最佳脱酸条件为脱酸温度40℃、超声功率400 W、油溶质量比1∶3、萃取次数3。在此条件下,MSO脱酸率可达95.69%。与碱炼脱酸相比,超声辅助乙醇脱酸制得MSO的α-生育酚、β-生育酚和总酚保留率分别提高了21.52%、17.92%和20.93%。Ultrasonic-assisted ethanol was used to deacidification treatment of mulberry seeds oil(MSO).Taking deacidification rate as the evaluation index,the deacidification process was optimized by orthogonal test on the basis of single factor experiments,and the deacidification effect was compared with alkali refining deacidification.The results showed that the optimal deacidification conditions were deacidification temperature 40℃,ultrasonic power 400 W,mass ratio of oil-soluble 1∶3,and extraction times 3.Under these conditions,the deacidification rate of MSO reached 95.69%.Compared with alkali refining deacidification,there was an increase of 21.52%,17.92%and 20.93%in the retention rates ofα-tocopherol,β-tocopherol and total phenols in MSO prepared by ultrasonic-assisted ethanol deacidification.
