Determination of antioxidants and UV stabilisers in PP FCM

The aim of this study is to develop an efficient analytical method with suitable detection limits, good repeatability, and accuracy for the determination of antioxidants and UV stabilizers in polypropylene packaging and different food simulants to deal with the increasing demands on food packaging material safety.
Dissolving the polypropylene food packaging with toluene and precipitating by methanol was demonstrated more effective than ultrasonic extract with acetonitrile or dichloromethane for extracting the additives. The method was successfully applied to six commercial polypropylene films for the determination of antioxidants and UV stabilisers (Acta Chromatographica, October 2016).
