摘要

We present a simple methodology for the simultaneous identification and determination of biogenic amines in food matrices, based on the use of a stable isotope-coded derivatization and liquid chromatography tandem mass spectrometry. The tagging reagent is N-hydroxysuccinimidyl ester of d_0/d_4-4-methoxybenzoic acid (d_0/d_4-4-MBA-OSu) which mainly functionalizes primary amines. The identification and structural characterization of tagged biogenic amines were exploited by matrix-assisted laser desorption/ionization–mass spectrometry (MS) and MS/MS. Multiple-reaction monitoring has been applied in the assay of biogenic amines in different foodstuffs, providing a method whose reliability is confirmed by the values of accuracy (12%) and by the calculated analytical parameters.
