Abstract: 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, NDPheA) 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.

Key words: N-nitrosamine, egg, chicken breast, chicken leg meat
