Keyword:  香椿籽油浸提精练理化特性;
Abstract: 采用索氏提取法萃取香椿籽油,通过单因素试验研究了不同因素对香椿籽油提取效果的影响,采用正交试验设计,得到了香椿籽油浸提的最优条件,获得了毛油的脱胶、碱炼等工艺参数,分析了精炼油的理化特性.香椿籽油浸提最佳工艺条件是:正己烷为浸提剂,香椿籽粒度60目,含水量7%,料液比1g:13 mL,温度85℃,浸提3 h;精炼工艺条件是:加水量为香椿籽油质量的4%,第1次水化1.0 h,第2次水化时间0.5 h;碱炼工艺条件是:初温为30℃,NaOH液浓度为14.42%、超NaOH用量为4%,保温静置6 h.香椿籽油中不饱和脂肪酸达90%以上,营养价值高,是优质的保健食用油.
