Identification of print related contaminants in food packaging

01 February 2016

Three different techniques: Direct Analysis in Real Time High Resolution Mass Spectrometry, Gas Chromatography Mass Spectrometry and Ultra-High Pressure Liquid Chromatography electrospray ionisation/HRMS were used to detect and identify print related molecules from the food-contact and print surfaces of 3 different packages with under-cured prints.
This approach tentatively identified or confirmed 110 compounds, including 35 print related molecules. The majority of compounds identified on food-contact surfaces were packaging monomers/byproducts, solvents/plasticizers, antioxidants/degradants, or slip agents/lubricants (Food Additives & Contaminants: Part A, 20 January 2016).
