摘要
挥发性羰基化合物是酒中重要的有害物质,为此建立了吹扫捕集-气相色谱法(P&T-GC)测定白酒和啤酒中的乙醛、丙醛、正丁醛、丁酮和丙酮。结果表明:此方法有较好的重复性,相对标准偏差在5.39%以下;检出限为1.27ng/mL～6.55ng/mL;5种物质的回收率在91.90%～98.24%之间。
Volatile carbonyls are possible sources of carcinogenicity in liquor and beer. So the analytical method of acetaldehyde, propionaldehyde, butyraldehyde, acetone and 2-butanone in liquor and beer of 4 samples have been established by Purge and Trap-Gas Chromatography. Results showed that this method achieved excellent reproducibility and the relative standard deviations were generally below 5.39 %. Detection limit of this method was 1.27 ng/mL-6.55 ng/mL. The recoveries were in the range from 91.90 % to 98.24 %.
