Determination of Heterocyclic Aromatic Amines in Cooked Commercial Frozen Meat Products by Ultrafast Liquid Chromatography

This paper describes a method for the determination of nine heterocyclic aromatic amines (HCAs) in commercial frozen meat products, which were sold in Turkey by ultrafast liquid chromatography (UFLC) with ultraviolet visible detection. HCAs are separated on a Shim-pack XR-ODS (7.5 × 3 mm, 2.2 μm). Varying levels of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) (up to 1.95 ng/g), 2-amino-3-methylimidazo[4,5-f]quinoxaline (IQx) (up to 4.17 ng/g), 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ) (up to 0.69 ng/g), 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) (up to 0.83 ng/g), 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (4,8-DiMeIQx) (up to 0.22 ng/g), 2-amino-3,7,8-trimethylimidazo[4,5-f]quinoxaline (7,8-DiMeIQx) (up to 0.94 ng/g), 2-amino-1-methyl-6-phenylimidazo[4,5-b] pyridine (PhIP) (up to 4.58 ng/g), 2-amino-9H-pyrido[2,3-b]indole (AαC) (up to 0.57 ng/g), and 2-amino-3-methyl-9H-pyrido[2,3-b]indole (MeAαC) (up to 3.51 ng/g) were detected in these commercial frozen meat products of Turkey. The data obtained show clearly that HCAs could be isolated in a very short time (5 min) by using UFLC.
