Researchers in Italy Developed New GC-MS and LC-MS Analytical Methods for the Determination of Ink Photoinitiators in Packaged Beverages

Researchers at the Universit di Camerino in Camerino, Italy have developed a new GC-MS and LC-MS technique for the determination of five ink photoinitiator residues: 2-isopropylthioxanthone (ITX), benzophenone, 2-ethylhexyl-4-dimethylaminobenzoate (EHDAB), 1-hydroxycyclohexyl-1-phenyl ketone (IRGACURE 184) and ethyl-4-dimethylaminobenzoate (EDAB) in packaged beverages. The work proposes a new method to analyze ink photoinitiator residues in polycoupled carton packaging and in contained food beverages.
