摘　　要：以冷榨胡萝卜籽油为原料,进行碱炼脱酸的工艺优化研究。分析碱炼温度、碱炼时间和碱液质量分数3个试验因素对冷榨胡萝卜籽油精炼率及碱炼脱酸率的影响,以及这3个试验因素间的交互作用对冷榨胡萝卜籽油碱炼脱酸率的影响。经单因素试验及响应面试验分析得出,对冷榨胡萝卜籽油的碱炼脱酸率影响最大的是碱炼时间,其次是碱液质量分数,最后是碱炼温度。冷榨胡萝卜籽油的碱炼温度70℃、碱炼时间57 min、碱液质量分数16%时,碱炼脱酸率最高,此时冷榨胡萝卜籽油的碱炼脱酸率可达86.91%,与软件预测值重合,证明最佳工艺预测值准确。The process of deacidification of cold pressed carrot seed oil by alkali refining was studied.The effects of the three factors on the quality of carrot seed oil were analyzed.The results of single factor and response surface analysis showed that alkali refining time was the most important factor affecting deacidification rate of cold pressed carrot seed oil,followed by alkali liquor mass fraction,and finally alkali refining temperature.When the alkali refining temperature of cold pressed carrot seed oil 70℃,the alkali refining time 57 min,and the mass fraction of alkali liquor 16%,the deacidification rate of cold pressed carrot seed oil could reach 86.91%,which coincided with the predicted value of software,which proved that the optimal process prediction value was accurate.
