The paper on “Detection and Identification of Oestrogen-Active Substances in Plastic Food Packaging Migrates” by Christian Kirchnawy and colleagues from the Austrian Research Institute for Chemistry and Technology was published online on December 5, 2013 in the peer-reviewed journal Packaging Technology and Science. The researchers applied a new procedure combining a yeast estrogen screen (YES) with gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography-mass spectrometry (HPLC-MS), The procedure allows for testing and identification of estrogen active migrants from plastic food contact materials (FCM). The suitability of their procedure was tested using 42 samples of virgin FCMs with no prior food contact to exclude contamination. Overall, estrogen activity was shown to be lower in comparison with other recent studies.
