Chemical components that form unintentionally during manufacture (eg. combination or degradation products), are especially important when assessing the safety of the food contact material (FCM). Lately the interest towards research of these non-intentionally added substances (NIAS) has been growing, and as more are known about the nature of these compounds, the better legislation and regulation can be made to ensure the safety of FCMs. \n\nThis Master\u2019s thesis discusses the possible NIAS in food contact paperboards. It first introduces concepts about paperboard manufacture, manufacturing chemicals, and food contact materials (FCMs). After this, the origin-based NIAS classification and NIAS groups such as reaction products, impurities, and contamination are discussed. The thesis then reviews some of the global legislation concerning FCMs and NIAS, focusing mainly on EU and US regulation. \n\nChapters 6 and 7 handle chemical analysis and risk assessment of paperboard FCM NIAS. These include eg. sample preparation techniques, analysis instrumentation, and estimation of component migration, dietary exposure and toxicology. Finally the thesis concludes by discussing some recycled and virgin paperboard NIAS found from recent literature, placing emphasis especially on the origins and routes of formation for the components.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Riitta Pitk\u00e4nen (rpitkane@jyu.fi) on 2018-08-27T07:11:21Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2018-08-27T07:11:21Z (GMT).
