摘要:
本研究建立了气相色谱-质谱联用仪(GC-MS)快速测定腊肠肉制品中7种N-亚硝胺类化合物的分析方法,建立并优化了冷冻液液萃取结合QuEChERS方法的前处理条件,考察了色谱柱、提取溶剂、固相吸附填料以及冷冻液液萃取对检测结果的影响。结果表明,优化后的检测方法操作简便,7种N-亚硝胺检出限均在0001 μg/g左右,线性范围在 0.01~050 μg/g,线性相关系数可达到0.999 2以上,回收率达到 82.20%~10515%,相对标准偏差为 2.56%~389%,重现性良好。该方法可操作性强,稳定性好,适用于肉制品中N-亚硝胺类化合物的批量检测分析。
Abstract:
In this study, an optimized analytical method of gas chromatography-mass spectrometry (GC-MS) combining frozen liquid-liquid extraction-QuEChERS for sample pretreatment was established for the determination of seven N-nitrosamines in sausage meat products. The limits of detections of seven N-nitrosamines were about 0001 μg/g, with the linear range of 0.01-050 μg/g, and the linear correlation coefficient more than 0.999 2. The recoveries of seven N-nitrosamines were 82.20%-10515% with the relative standard deviations of 2.56%-389%. The method is easy to operate and stabile, suitable for batch analysis of N-nitrosamines in meat products.
