Microwave nitrates
WebNo NNAs were detected in the bacon or fried-out fat after cooking in a microwave oven for 45 sec/slice. However, excessive cooking of the bacon in a microwave oven (75 sec/slice) does produce levels of NPYR up to 5 ng/g. The minimum detectable level of NPYR was 2.08 ng/g and that of NDMA was 0.76 ng/g.
