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.

Article Number: 2010935
Description: Studies repeatedly show that in a large number of foods, mineral oils migrate in detectable concentrations from the packaging or printing inks into the food. The analysis of foodstuffs with regard to the migration of mineral oil is becoming increasingly important. At the same time, however, the need for information on measurement precision, repeatability and comparability of the test methods is also increasing. The determination of defined mineral oil components from jute bags by extraction are the objectives of this proficiency test. The proficiency test is suitable for all laboratories that routinely perform or would like to establish the examination of mineral oil contents in jute bags.
