Abstract
Nitrosopyrrolidine (NO‐Pyr) formation in bacon is primarily dependent on frying temperature and not time. Cooking methods affect the amount of NO‐Pyr formed: pan frying produces the highest level of NO‐Pyr with variable concentrations formed on baking, broiling and cooking in a “baconer.” Microwave oven treatment produced the lowest amount of NO‐Pyr. A model system study of the decarboxylation of nitrosoproline shows this precursor, which may be present in bacon, is maximally converted to NO‐Pyr at 185°C near the recommended temperature for frying.
