Objective To analyze volatile organic compounds in heatable plastic food packages. Methods With methanol as solvent, standard solutions of isopropyl alcohol, ethyl acetate, benzene, butyl acetate, ethylbenzene, m / p-Xylene, o-Xylene and cyclohexane were prepared. Headspace gas chromatography and mass spectrometry ( HS / GC-MS) technology were used to determine and analyze eight volatile organic compounds ( VOCs) in seven heatable plastic food packages. Differences of VOCs in the packages before and after heating were compared. Results The content of cyclohexane in original yoghurt plastic package after heating was significantly higher than that in unheated package. The content of isopropyl alcohol in heated Xiaosurou plastic box obviously increased. The changes in the content of VOCs in Zongzi plastic bag, corn plastic bag, milk tea plastic cup, self-heating plastic dinner box and microwaveable plastic box were relatively small. Conclusion Residues of benzenes in the seven packages all exceeded the national standards.
