Sažetak
The objective of this study was evaluation of the suitability of recycled paper materials for direct food contact applications. Safety evaluation of various recycled paper grades was conducted in order to identify the contaminants that are present in certain types of recycled papers which have the ability to migrate into the food and thus potentially endanger consumers’ health. Fort the purpose of the investigation, three different types of recovered papers had been submitted to a chemical deinking flotation and the handsheets that were formed after each flotation deinking trial were analyzed on the presence of residual chemical contaminants: heavy metals (Cd, Pb, Hg), primary aromatic amines, phthalates, diisopropylnaphthalenes (DIPN) and polychlorinated biphenyls (PCB). The conducted research showed that most common contaminants present in the analysed papers were DIPNs and phthalates which were found at highest concentrations in brown packaging grades. However, according to present toxicological assessments, detected amounts of DIPNs and phthalates do not impose a health risk to the consumers. Research thus demonstrated that all tested papers regarding the analyses done within this study are proved suitable to be used in direct contact with food.
