Original Kurzfassung:
The safe use of paper and cardboard for food packaging applications is a major area of
investigations. Since food packaging materials are mostly printed with inks it is of vital
importance to ensure that the ink is not transferred out of the packaging and thereby
endangers humans? health by pollution. Migration is an issue which food packaging
material manufactures have to be aware of as several regulations restrict contamination
of food unless the substances are approved, harmless or the concentrations are below a
set limit of 60 ppm per kilogram of foodstuff.
In this presented work a method was developed to test food packaging materials for
their migration behavior. Tenax® (also known as modified polyphenylene oxide) is
commonly used as food simulant for dry fatty food. The structure of Tenax® permits
the adsorption and desorption of volatile substances which makes it suitable for
simulation of the migration processes into foodstuff. Commercially available pizza
boxes were used for the investigations. In accordance with EU regulations the
parameters for this application were set at 2 h and 70°C. The extraction was performed
with acetonitrile followed by analysis with GC/MS, Headspace-GC/MS and HPLC/MS.
Furthermore, time and temperature dependency of the migration process are
investigated since these parameters have a significant impact on the transfer of
constituents.
