The present study provides an exhaustive set of migration data for Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate (Irganox 1076) from low density polyethylene (LDPE) in several food matrices. Irganox 1076 was used as model migrant because it represents one of the typical substances used as antioxidant in food packaging polymers. Kinetic (time-dependent) migration studies of Irganox 1076 were performed into selected foodstuffs, chosen with different physical-chemical properties and in relation to the actual European food consumption market The effect of the fat content and of the temperature of storage on the migration from plastics packaging was evaluated. The results showed that migration increased with fat content and storage temperature. All data obtained from real foods were also compared with data obtained from simulants tested in the same conditions. In all studied cases, the kinetics in simulants were higher than those in foodstuffs. The work provides data valuable to extend the validation of migration model developed on simulants to foodstuffs themselves.
