摘  要：
研究建立一种适用于肉制品中9种挥发性N-亚硝胺含量的气质联用快速检测方法。实验优化提取溶剂和色谱柱对提取和分离检测影响的条件,同时考察4种固相萃取单柱(酸性氧化铝、C18、活性炭、PSA)和1种双填料的混合固相萃取柱(PSA-C18)的净化效果。结果表明:本检测方法的线性系数均可达到0.999 2以上;线性范围为0~10μg/m L;重现性良好,相对标准方差均≤3.2%;回收率为85%~98%;检测限分别为N-亚硝基二甲基胺1.0μg/kg、N-亚硝基甲基乙基胺2.1μg/kg、N-亚硝基二丁基胺0.8μg/kg;其他均为0.5μg/kg。该方法能够满足测定肉及肉制品中N-亚硝胺的残留含量的需要。

摘  要：
This research has established a rapid detection method for nine volatile N-nitrosamines in meat and meat products by using gas chromatograph-mass spectrometry(GC-MS). In this experiment, we investigated the effect of extraction solvent type and chromatographic conditions on the extraction and separation of the target compounds. Meanwhile, comparison of solid-phase extraction(SPE) cartridges packed with acidic alumina, C18, activated carbon or PSA, or both C18 and PSA was carried out for the purification of the N-nitrosamines. Results showed that the linear range of the proposed method was 0-10 μg/m L with correlation coefficients more than 0.999 2. Good reproducibility was observed with relative standard deviation(RSD) not exceeding 3.2% and the mean recoveries were in the range of 85%-98%. The detection limits for N-nitrosodimethyl amine(NDMA), N-nitrosomethyl ethyl amine(NMEA), N-nitro sodibutyl amine(NDBA) and six other N-nitrosamines were 1.0, 2.1, 0.8 and 0.5 mg/kg, respectively. This method can meet the requirement for the determination of N-nitrosamine residues in meat and meat products.
