Abstract
Most food products are packaged. Paper is mainly used for this purpose, especially due to the increased awareness of the plastics impact on the environment. Due to its good printability, it is usually printed with UV inks. These contain photoinitiators, which have a low molecular weight and can be prone to migration. However, in order to comply with the framework regulation (EC) 1935/2004, printing inks must not release substances to the packaged food in quantities that could lead to undesirable changes. Therefore, this work focused on the development of a highly sensitive, selective and accurate SPME-GC-MS method for the determination of selected photoinitiators in paper and board food packaging materials. An internal standard method was used for quantification, so method is optimised to be less labour intensive and require little sample preparation time. Selected packaging materials from supermarkets were analysed and photoinitiators were found in some of them.
Abstract (croatian)
Većina prehrambenih proizvoda je pakirana. U tu se svrhu uglavnom koristi papir, posebice zbog povećane svijesti o utjecaju plastike na okoliš. Zbog dobre mogućnosti ispisa većina ih se tiska UV-tintama. One sadrže fotoinicijatore koji su niske molekularne mase te su skloni migraciji. Kako bi bile usklađene s Uredbom (EZ) 1935/2004, tiskarske tinte ne smiju ispuštati tvari u pakiranu hranu u količinama koje bi mogle dovesti do neželjenih promjena. Stoga je cilj ovog rada razvoj vrlo osjetljive, selektivne i točne SPME-GC-MS metode za određivanje odabranih fotoinicijatora u papirnim i kartonskim materijalima za pakiranje hrane. Za kvantifikaciju je korištena interna standardna metoda, tako da je metoda optimizirana da bude manje radno intenzivna i zahtijeva malo vremena za pripremu uzorka. Analizirani su odabrani materijali za pakiranje iz supermarketa te su u nekima od njih pronađeni fotoinicijatori.
