title: Plasticizers in Brazilian food-packaging materials acquired on the retail market.
abstract: Packaging materials intended for direct food contact were acquired on the Brazilian retail market and analysed for their plasticizer content. Analyses were carried out by gas chromatography with flame ionization detection. Di-2-ethyl-hexyl adipate (DEHA), di-2-ethyl-hexyl phthalate (DEHP) and di-iso-decyl phthalate (DIDP) plasticizers were identified in films and closure seals in concentrations ranging from 12 to 19% (w/w), 15 to 44% (w/w) and 10 to 11% (w/w), respectively. Brazilian regulations state that for use with foods with a fat content above 5%, the levels of DEHP and DIDP in the plastic material should be no greater than 3%. The results obtained demonstrate a lack of conformity. It would be advisable to include information on the labels of packaging materials about their restrictions of use in order to advise manufacturers and consumers about their proper usage.
