Report of an inter-laboratory comparison from the European Union Reference Laboratory for Food Contact Materials: ILC01 2015 – Temperature control during migration tests by article filling

摘要

This report presents the results of an inter-laboratory comparison (ILC) on the temperature control during migration testsby article filling organised by the EURL-FCM, Ispra (Italy). Participants carried out a migration test by article filling inprovided polypropylene cups (volume 0.3 L) with food simulant D1 (ethanol 50 %, v/v) at 70°C for 2 h and monitored thetemperature of the food simulant inside one of the test specimen during the contact phase and provide details for theoperating procedure. The participation to the ILC was satisfactory. The results show that 30% of the 53 migrationexperiments performed by the 45 laboratories were successful (scoring 100%) meaning that the temperature of thefood simulant was in the desired range during the full contact time. It is clear that this result will trigger furtherdiscussion to improve the temperature control during a migration test. The information provided by the laboratoriesthrough the questionnaire gives a first insight in the factors that can be important to reach a satisfactory score. Thisdiscussion should lead to the selection of one or more methods for temperature control during migration testing. Theseselected methods need to be compared in a future ILC.
