摘　　要：探究粗制鸭肝油脂的最佳提取工艺,考察精炼工艺主要参数对鸭肝油脂精炼效果的影响,并分析精炼过程中脂肪酸组成及含量变化。结果表明:最优提取工艺为料液比4∶1(g/mL)、无水乙醇与正己烷体积比1∶1、超声温度50℃、超声时间30 min,在此条件下,鸭肝油脂提取率55.74%;最佳精炼工艺为脱胶水添加量(以粗制鸭肝油脂质量计)10%、脱酸超碱量(以脱胶油质量计)0.6%、活性白土用量(以脱酸油质量计)10%、真空脱臭2.0 h。精炼后油脂的酸价为1.17 mg/g,过氧化值为0.1538 g/100 g;鸭肝油脂中共检测出16种脂肪酸,其中饱和脂肪酸5种,单不饱和脂肪酸4种,多不饱和脂肪酸7种。The optimal extraction process for crude duck liver oil was explored,the influence of main refining process parameters on the refining effect of duck liver oil was investigated,and the changes of fatty acid composition and content during the refining process were analyzed.The results showed that the optimal extraction process was material to liquid ratio 4∶1(g/mL),volume ratio of anhydrous ethanol to nhexane 1∶1,ultrasonic temperature 50℃,and ultrasonic time 30 min.Under the conditions,the extraction rate of duck liver oil was 55.74%.The optimal refining process was addition amount of debonding water 10%(based on the mass of crude duck liver oil),addition amount of excess alkalinity 0.6%(based on the mass of degummed oil),addition amount of active clay 10%(based on the mass of deacidified oil),and 2 h of vacuum deodorization.The acid value of refined oil was 1.17 mg/g,and the peroxide value was 0.1538 g/100 g.A total of 16 fatty acids were detected in duck liver oil,including 5 saturated fatty acids,4 monounsaturated fatty acids,and 7 polyunsaturated fatty acids.
