Abstract
Aquatic animals are susceptible to N-dimethylnitrosamine pollution in water quality or feed, which is a non-negligible problem in food safety detection. Gas chromatography/triple four-stage mass spectrometry combined with QuEChERS was used to detect N-dimethylnitrosamine in duck and poultry meat, and acetonitrile, salting-out agent and purifying agent were used to extract duck and poultry meat samples. The results of detection and analysis showed that the results were good. The standard curve was highly correlated in the range of 5ng/mL to 1000ng/mL (R2 > 0.9997). The recovery of standard sample was 82.51%-115.42%, RSD was 1.89-2.99, instrument detection limit was 4.4ng/mL and method detection limit was 0.44ng/g after adding standard sample and matrix effect treatment. The results showed that the recovery of standard sample was 82.51%-115.42%, RSD was 1.89-2.99, and instrument detection limit was 4 ng/mL. Other methods can reduce the operation steps and improve the detection accuracy.
