Screening for contaminants in paper and board for foodstuffs
Due to large knowledge gaps in chemical composition and toxicological data for substances involved, paper and board food-contact materials have been emerging as a FCM type of particular concern for consumer safety. This study describes the development of a step-by-step strategy for tentative identification of relevant substances. As a case study, two fractions from a recycled pizza box sample were used which exhibited aryl hydrocarbon receptor activity. Of 75 tentatively identified substances, 15 were initially selected for further testing in vitro; however, only seven were commercially available, tested in vitro and quantified (Food Additives & Contaminants: Part A, 1 June 2016).
