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. 2 h at 175 degrees C, 30 min at 130 degrees C, 1 h at 100 degrees C followed by 10 days at 40 degrees C, 10 days at 20 degrees 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.
