Prevention of the formation of mutagenic and/or carcinogenic heterocyclic amines by food factors

Introduction of phenolic antioxidants, thiol compounds and reductones into the heated model system composed of glucose/glycine/creatinine was effective to scavenge the intermediary pyrazine cation radical and to reduce the mutagenicity due to imidazoquinoxaline heterocyclic amines. Addition of a reductone, ascorbate or erythorbate, at 0.3% to ground beef effectively reduced the mutagenicity of cooked hamburger. Mutagenicity of cooked hamburger was also decreased by addition of glucose at more than 0.7% to ground beef.
