Migration of 17 Photoinitiators from Printing Inks and Cardboard into Packaged Food - Results of a Belgian Market Survey

摘要

Photoinitiators are widely used to cure ink on packaging materials used in food applications such as carton boards and can contaminate the food by migrating into the food. In this contribution, a fast and reliable confirmation method for the determination of photoinitiators in dry foodstuffs is described: benzophenone (BP), 4,4'-bis(diethylamino) benzophenone (DEAB), 2-chloro-9H-thioxanthen-9-one (CTX), 1-chloro-4-ropoxy-9H-thioxanthen-9-one (CPTX), 2,2-dimethoxy-2-phenyl acetophenone (DMPA), 4-(dimethylamino) benzophenone (DMBP), 2-ethylanthraquinone (EA), 2-ethylhexyl-4-dimethylaminobenzoate (EDB), ethyl-4-dimethylaminobenzoate (EDMAB), 4-hydroxybenzophenone (4-HBP), 1-hydroxycyclohexyl phenyl ketone (HCPK), 2-hydroxy-4-methoxybenzophenone (HMBP), 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone (HMMP), 2-isopropyl-9H-thioxanthen-9-one (ITX), 4-methylbenzophenone (MBP), 4,4'-bis(dimethylamino) benzophenone (MK) and 4-phenylbenzophenone (PBZ).
