E. Richling et al., ANALYSIS OF HETEROCYCLIC AROMATIC-AMINES IN WINE BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY ELECTROSPRAY TANDEM MASS-SPECTROMETRY, Journal of chromatography, 791(1-2), 1997, pp. 71-77
High-performance liquid chromatography-electrospray tandem mass spectr
ometry (HPLC-ESI-MS-MS) was used for the analysis of heterocyclic arom
atic 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 (MeA alpha C) 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 w
ere found, with MeA alpha C 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. (C) 1997 Elsevie
