Abstract

The safe use of recycled paper and board material for food packaging applications is a major area of investigations. Therefore, the aim of current study was to evaluate the amount of heavy metals in recycled paper pastry packages and measurement of migration over the time into pastries. In this study, the presence of heavy metals in common confectionery packaging and effects of storage time and kind of pastry on the migration are investigated. The results of the study indicate that harmful metals such as Pb are detected at high concentrations in most of the recycled boxes that are used for pastry packaging, and heavy metals could migrate from the recycled packages into food during usage. It seems that the procedure of preparing recycled paperboard for food packaging should be reconsidered. © 2016 Akademiai Kiado.
