以冷榨铁核桃油为原料,进行碱炼脱酸工艺研究,在单因素试验基础上,采用Box–Behnken设计响应面法优化碱炼脱酸工艺条件。经优化后得到的优化工艺条件为碱炼浓度为17°Bé、超碱量0.14%、反应时间32 min、碱炼温度60℃、搅拌速率60 r/min。在此条件下,碱炼脱酸后的铁核桃油的酸价可降至0.55 mg KOH/g。

Iron walnut oil extraction by cold pressed was used to study carried out in alkali refining acid stripping. Based on single factor experiment,the optimization conditions for iron walnut oil deacidification by response surface method（RSM） was performed.The result showed that the optimum parameters were the alkali refining concentration of 17°Bé,the ultra–alkali capacity of 0.14%,the alkali refining time of 32 min,and the alkali refining temperature of 60 ℃.With the above processing,the acid...
