ABSTRACT THE suggestion that nitrosamines could be formed in cured meats1 has prompted much research into the fate of added nitrite in these foods. Because of their carcinogenicity, the major effort has been directed towards nitrosamine formation _in vitro_ in cured meats and _in vivo_, but other nitrosations reported have been those of proteins2, thiols3 and creatine and creatinine4. We have recently reported our results on the nitrosation of liquid smoke emulsions in model systems5 and we are prompted to report our studies of phenol nitrosation in smoked bacons by a recent suggestion that competitive nitrosation of phenolic residues may reduce the amount of nitrosamine formation6.
