Studies performed in 2001 and 2003 surveyed the release of carcinogenic nitrosamines and nitrosatable substances from rubber toy balloons by extraction with artificial saliva and gas chromatography-thermal energy analysis (GC-TEA). 81% of the 16 in 2001 sampled balloons and 93% of the 14 in 2003 sampled balloons released nitrosamines above the recommended(More)
The case of isopropylthioxanthone (ITX) showed conclusively that the ingredients of ultraviolet printing inks may migrate into packaged foodstuffs. For multilayered materials like beverage cartons, the only way that mass transfer can occur is by the so-called set-off effect. In contrast, in the case of rigid plastics like yoghurt cups, two other methods of(More)
Migration from recycled paperboard was monitored after 2, 4 and 9 months of storage for six test foods industrially packed in five configurations, four with internal plastic films. After 9 months, the migration of mineral oil saturated hydrocarbons into foods directly packed in the paperboard amounted to 30-52 mg/kg, which corresponded to 65%-80% of those(More)
In  a surveillance study from 2008 to 2011, in total 310 food products, predominately packed in cartonboard, were collected from the German market. First, the packaging materials were analysed for their content of six photo-initiators and five amine synergists by high-performance liquid chromatography with diode array detection (HPLC-DAD). If high amounts(More)
– Die Verordnung (EG) Nr. 2023/2006 (GMP-Verordnung) verdeutlicht, dass es keine ,,ungeregelten‘‘ Bedarfsgegenstände und ,,ungeregelten‘‘ Substanzen gibt, die aus Lebensmittelbedarfsgegenständen migrieren. Der Artikel 3 der Verordnung (EG) Nr. 1935/ 2004 (Rahmenverordnung) gilt allgemein. Es gibt allerdings viele Substanzen und(More)
