The suitability of alternative fatty food simulants for overall migration testing under both low‐ and high‐temperature test conditions

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. 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.
