摘　　要：对北京、天津和保定市场的鸡产品(鸡蛋和鸡肉)中9种N-亚硝胺(N-二甲基亚硝胺、N-二乙基亚硝胺、N-甲基乙基亚硝胺、N-二丁基亚硝胺、N-二丙基亚硝胺、N-亚硝基哌啶、N-亚硝基吡咯烷、N-亚硝基吗啉、N-亚硝基二苯胺)含量进行了测定分析。结果表明:3个地区所含有的N-亚硝胺的种类和含量均存在差异,不同地区的同一鸡产品中所含有的N-亚硝基化合物也不同,即使同一地区、不同鸡产品中N-亚硝基化合物组成也不相同。在天津市场鸡产品中,N-二丁基亚硝胺的最高含量为0.45 ng/mL(鸡腿肉);在河北市场鸡产品中,N-二乙基亚硝胺的最高含量为0.91 ng/m L(鸡蛋中);在北京市场鸡产品中,N-二乙基亚硝胺的最高含量为1.93 ng/mL(鸡腿肉)。这可能与3个地区所选择的饲料原料和饲养模式有关。In this experiment, nine kinds of N-nitrosamine（N-nitrosodimethylamine, NDMA; N-nitrosodiethylamine, NDEA; N-nitrosomethylethylamine, NMEA; N-nitrosodi-n-butylamide, NDBA; N-nitrosodi-n-propylamine, NDPA; N-nitrosopiperidine, NPIP; N-nitrosopyrrolidine, NPYR; N-nitrosomorpholine, NMOR; N-nitrosodiphenylamine, NDPhe A） content of chicken products（eggs and chicken） in the markets of Beijing-Tianjin-Hebei Regions were measured and analyzed. The results showed that it is different not only the kinds but also the quantity in content of N-nitrosamines in the three regions. N-nitrosamine compounds composition of the same part of chicken products in different regions are different, even in the same area, N-nitrosamine compounds composition of the different part of chicken products in same chicken product composition is not the equal. Content of NDBA of chicken leg meat was 0.45 ng/mL and was the highest in chicken products of Tianjin market, content of NDEA of egg was 0.91 ng/mL and was the highest in chicken products of Hebei market, and content of NDEA of chicken leg meat was 1.93 ng/mL and was the highest in chicken products of Beijing market. This may be related to the selection of feed materials and feeding patterns in three regions.
