Können Nanomaterialien aus Lebensmittelverpackungen migrieren?

Migration of Nanomaterials
Nanotechnology promises benefits for the application in food packaging plastics, but a general concern about food safety can be recognised. Since the knowledge about the exposure of consumers to nanomaterials is still limited, sensitive methods are needed that are suitable to determine a possible migration of nanomaterials from packaging into food. In our study we demonstrate that the combination of inductively coupled plasma mass spectrometry (ICP-MS) and asymmetric flow field-flow fractionation (AF4) are successful techniques for the separation and detection of nanomaterials in food simulants. In none of our measurements a migration of nanomaterials out of the polymeric matrix was detected.
