Abstract
High-performance liquid chromatography–electrospray tandem mass spectrometry (HPLC–ESI-MS–MS) was used for the analysis of heterocyclic aromatic amines (HAAs) in 25 wines from various regions. In 24 wines under study HAAs were detected in the low ng/l range. 2-Amino-3,4-dimethyl-3H-imidazo[4,5- f]quinoxaline (MeIQx) and 2-amino-3-methyl-9H-pyrido[2,3- b]indole (MeAαC) were found to be the most widely distributed HAAs in the wines under study. There was a difference in the presence of HAAs in white and red wines. In the latter, higher concentrations were found, with MeAαC in amounts ranging from <7.5 to 107 ng/l. Compared to the quantities of HAAs evaluated in meat and meat products, the amounts found in wines are 100–1000-fold lower.
