Objective To evaluate the migration risk of the phthalic acid esters (PAEs) from the packaging of fast food and breakfast. Methods Totally 42 batches of disposable fast food box were collected and the contents of the PAEs were determined by gas chromatography-mass spectrometry, according to GB/T 21928-2008 (Determination of phthalate esters in food plastic packaging materials). The migration risk was also investigated with the corresponding soaking condition according to GB/T 23296.1-2009. Results There are 26 batches (61.9%) of the 42 batches were found to have PAEs. In this event, the contents of PAEs in 24 batches were in the range of 0~10 mg/kg with the highest content 93.5 mg/kg. In the migration experiment, only 0.06 mg/kg of diethylhexyl phthalate (DEHP) was detected in the samples which were of the highest content of PAEs. Conclusion The exposure level of PAEs in the packaging of fast food and breakfast is lower than 100 mg/kg, which is less risky of migration during normal use.
