摘要
介绍了采用ＦＦＡＰ键合毛细管柱直接进样测定白酒中５种高碳脂肪酸乙酯的方法，操作简捷，定量准确，检测限低达０４ｍｇ／Ｌ。用该法测定了各种香型近９０个白酒样品。改变色谱条件后，在一次直接进样分析中除能测定高碳脂肪酸乙酯外，而且还能对白酒中醇、酯、醛、酮以及有机酸等５２种香味组分进行定量测定，结果重现性良好。
Five ethyl esters of long_chain fatty acids in Chinese spirits have been determined by GC on a FFAP bonded capillary column with direct injection technique.The method has a detection limit of 04 mg/L.Fifty two flavor components in spirits,such as alcohols,esters,aldehydes,ketones and organic acids,can also be determined along with ethyl esters of long_chain fatty acids.Nearly 90 kinds of Chinese spirits with different flavors have been determined by this method with satisfactory results.
