摘　　要：通过对不同酒类中月桂酸乙酯、棕桐酸乙酯、油酸乙酯和亚油酸乙酯4种高级脂肪酸乙酯的研究,建立气相色谱法对其进行检测。由于不同酒类4种高级脂肪酸乙酯含量差异较大,本方法线性范围为0.5 mg/L~10.0 mg/L,范围覆盖白酒从基酒到成品各环节含量;检出限为0.2 mg/L~0.7 mg/L,定量限为0.5 mg/L~2.0 mg/L;样品加标回收率为86.98%~111.17%。A gas chromatography method was established to detect four higher fatty acid ethyl esters,namely ethyl laurate,ethyl palmitate,ethyl oleate,and ethyl linoleate,in different alcoholic beverages.As the content of ethyl ester of four kinds of higher fatty acids in different wines varies greatly,the linear range of this method is 0.5 mg/L~10.0 mg/L,covering the content of Baijiu from base liquor to finished product;The detection limit is 0.2 mg/L~0.7 mg/L,and the quantification limit is 0.5 mg/L~2.0 mg/L;The recovery rate of sample spiked is 86.98%-111.17%.
