Description: Current analyses show, that in a wide range of food verifiable concentrations of mineral oil or printing inks pass into foodstuff. The analysis of foodstuff concerning the migration of mineral oil is increasingly gaining importance since the last years. At the same time the requirement of measuring precision, repeatability and comparability of the method of analysis increase. In this proficiency testing defined mineral oil fractions from cardboard by extraction are determined. This proficiency testing is suitable for all laboratories which carry out the testing of the mineral oil content of cardboard on a routine basis or are currently establishing such a method.
