Abstract: Some possible residual solvents in food packaging materials like acetone,ethanol,ethyl acetate,methyl ethyl ketone,isopropyl alcohol and toluene were analyzed by gas chromatography.The residual amounts of solvent and benzene series in some milk packaging materials were determined by using DNP chromatographic column separation and FID detector.Results showed that 11 kinds of solvents could be separated better,with a good linear,and the minimum detect limit could reach 0.000 4 mg/m2.The method is simple,rapid and reproducible,so it can satisfy the analysis of residual solvents in plastic packaging materials.
