粗大鲵油通过精制可除去其中的一些磷脂、蛋白质、游离脂肪酸和色素等杂质。结果表明：粗大鲵油精制工艺最佳参数为采用40%磷酸，添加量为1%(占油质量)，70℃脱胶1 min；采用3%氢氧化钠溶液，添加量为1．5%(占油质量)，65℃脱酸30 min；添加1%(占油质量)的活性白土，60℃脱色30 min；85℃下减压蒸馏脱臭30 min。在最佳工艺条件下，所得精制大鲵油澄清透明，略显淡黄色，鱼腥味较轻。对精制后的大鲵油采用气相色谱法共鉴定出25种脂肪酸，其中不饱和脂肪酸( UFA)含量为69．81%，多不饱和脂肪酸( PUFA )含量为27．60%，饱和脂肪酸( SFA )含量为22．64%。

The impurities in crude giant salamander oil such as phospholipids, protein, free fatty acid and pigment could be removed through refining process. The results showed that the optimal refining parame-ters of crude giant salamander oil were obtained as follows:dosage of 40% H3 PO4 1% ( based on the oil mass) , degumming for 1 min at 70℃; dosage of 3% NaOH solution 1. 5% ( based on the oil mass) , deacidification for 30 min at 65℃;dosage of activated clay 1% ( based on the oil mass) , bleaching for 30 min at 60℃;reduced pressure deodorization for 30 min at 85℃. Under these conditions,the refined giant salamander oil was clear, transparent and light yellow with little fishlike smell. Twenty-five kinds of fatty acids in refined giant salamander oil were identified by GC. The contents of unsaturated fatty acids ( UFA ) , polyunsaturated fatty acids ( PUFA ) and saturated fatty acids ( SFA ) were 69. 81%, 27. 60% and 22. 64%, respectively.
