The three IQ (2-amino-3-methylimidazo[4,5-f]quinoline) compounds IQ, MeIQx (2-amino-3,4-dimethyl[4,5-f]quinoxaline) and MeIQ (2-amino-3,4-dimethylimidazo[4,5-f]quinoline) have been found in boiled pork juice. To determine which Maillard reaction products are important in the formation of IQ-type mutagens in boiled pork juice, six Maillard reaction products
