Does recycled packaging contaminate fast foods?
Packaging materials can contain MOSH and MOAH concentrations due to the use of mineral oil in printing inks and recyclates. As MOAH is assumed to be carcinogenic, migration into food products should be avoided. This work dealt with the analysis of MOSH and MOAH in fast food packaging and the migration from pizza boxes into the pizza. Various fast food packaging materials were analyzed for their mineral oil contents. The samples showed mineral oil contents up to 682 mg/kg for MOSH and 92 mg/kg for MOAH. Despite the high mineral oil concentrations in the pizza boxes, only minor migration of MOSH and MOAH into pizza could be observed, even under worst case test conditions.
