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 four
antioxidants: Butyle
ted hydroxy toluene (BHT), Bisphenol A (BPA),
Pentaerythritol tetrakis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) (Irganox
1010), and Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate
(Irganox 1076), was studied 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 ºC, during 20 days. Samples were
analyzed by high performance liquid chromatography (HPLC) with UV
detector. In general, the studied compounds appeared to be more stable in both
Ethanol (95%) and simulant B than in simulants A and C.
