The contents of N-nitrosamines and its precursors such as TMAO-N, TMA-N, DMA-N, nitrite-N and nitrate-N after broiling of sea-bream, Filefish, and Squid upon gas range were investigated. The contents of TMAO-N decreased remarkably in all tested fishes after broiling. TMA-N increased approximately 5 and 4 times in squid and sea-bream, respectively. DMA-N increased in all tested fishes after broiling, and especially showed the highest in squid. Nitrate-N descreased in all tested fishes after broiling, while nitrite-N increased. N-nitrosamines detected in broiled fishes were NDMA and NDEA. The contents of NDMA were in the range of 9.5~14.1μg/kg and NDEA were 1.2~2.5 ㎍/kg.
