Hazardous chemical contaminants in recycled pastry packaging

The aim of this study was to determine which hazardous chemical pollutants were found in paper and cardboard samples used for pastry packaging, and to measure the migration of pollutants over time into the pastries.
The results of the study indicate that harmful compounds such as benzophenone and dibutyl phthalate are present at high concentrations in most recycled boxes used for pastry packaging. Since the migration of some of the hazardous compounds from the packaging materials into the pastries under normal conditions was indicated, it is recommended that the procedure for preparing pastry packaging materials should be reconsidered and improved (Technologia Alimentaria, February 2017).
