Abstract
The suitability of various alternative, volatile fatty food simulants for overall migration testing was investigated under both low‐ and high‐temperature test conditions. The overall migration into olive oil from a large number of commercially used food packaging materials applying various low‐ and high‐temperature test conditions (e.g. 2h at 175°C, 30min at 130°C, 1h at 100°C followed by 10 days at 40°C, 10 days at 20°C) was determined. The results were compared with overall migration from these samples into iso‐octane, 50% or 95% ethanol and isopropanol under appropriate test conditions. The samples investigated include homogeneous plastic films, laminates, coated board samples, a coated can, and articles. The results of the study indicate that iso‐octane, 95% ethanol and isopropanol are suitable alternative fatty food simulants for overall migration testing under various time and temperature conditions.
