Abstract in English
Additive migration levels in food simulants from polymeric materials that
are intended to be into contact with food can be affected by additive stability
under the migration test conditions. In this work, the stability of two
plasticizers: Diethylhexyl phthalate (DEHP) and Dibutyl phthalate (DBP) was
studies in aqueous food simulants A, B, C and ethanol 95% (as a substitute for
olive oil- which is a fatty food simulant- simulant D), at different temperatures
20, 40 and 70 C0, during 20 days. Samples were analyzed by high performance
liquid chromatography (HPLC) with UV detector.
In general, DEHP and DBP plasticizers appeared to be more stable in both
Ethanol (95%) and simulant C than in simulants A and B, while, they are less
stable, even at low temperatures, in Simulant B than in simulant A .
