title: Review of methodologies for the determination of nonvolatile N-nitroso compounds in foods.
abstract: An attempt has been made to briefly review methods available for the determination of total N-nitroso compounds, N-nitrosamides, N-nitrosamino acids, and miscellaneous other nonvolatile N-nitroso compounds in foods and beverages, giving special emphasis to the progress made during the past five years. It appears that a wide variety of acceptable methods are available for N-nitrosamino acids and simple hydroxylated N-nitrosamines, but none of them has yet been adequately validated. Only limited progress has been made for the analysis of N-nitrosamides, N-nitroso sugar amino acids, and other N-nitroso compounds. Various mass spectrometric methods available for the determination and confirmation of these compounds are also discussed.
