Abstract
By using the improved QuEChERS extraction and purification method and gas chromatography-mass spectrometry(GC-MS)technology,the determination method of 12 kinds of nitrosamines in various kinds of food was established,which was separated by DB-HeayWAX column,qualitatively and quantitatively analyzed by mass spectrometry,and quantified by matrix-matched external standard method.The results showed that the linear correlation coefficients of 12 kinds of nitrosamines within concentration range of 2.0-100.0 μg/L were all greater than 0.995.The detection limits of the targets in different matrices(cured meat products,salted aqustic products,pickled vegetables,beer)were all lower than 0.2 μg/kg,and the recovery rate is 81.8％-119.1％.It indicated that this method had good reproducibility and sensitivity,which was simple to operate,and was suitable for qualitative and quantitative analysis of 12 kinds of trace nitrosamines in various foods.关键词
