- Abstract
With the concern of food safety, countries have paid more and more attention to the detection technology of harmful substances in food, and put forward higher requirements for testing items and speed. In this paper, 18 kinds of toxic and harmful substances in food were detected by gas chromatography-mass spectrometry. These include plasticizers, aromatic amines, antioxidants, photoinitiators, flavors and solvents, and solvent extraction. Qualitative determination was performed by GC-MS full scan. The linear relationship of various substances in the range of mass concentration of 0.5-5.0 mgL-1 is good, and the correlation coefficient R>0. 9943; The addition recovery of the concentration of 0.10, 0.20, 0.40mg•L-1 was 74.9%~121.3%, and the relative standard deviation RSD was 1.4%~6.8% (n=6); the detection limit range was 1.5 to 80.0 μg·L-1. The method completes the separation and detection of 18 kinds of toxic and harmful substances in 20 minutes. The results are accurate, reproducible, simple, sensitive and accurate. It is suitable for rapid and sensitive detection of various toxic and harmful substances in food plastic packaging materials.
