Food and packaging interactions: tailoring fatty food simulants

摘要

Migration of paramagnetic probes from rigid PVC within 24 h at 50 deg.C depends on the simulant to a considerable xtent. With a strongly swelling simulant like tert. butyl acetate, the rate of diffusion is governed by the rate of penetration of the medium into the polymeric network. Isooctane has a very weak inter- action with rigid PVC. With a mixture of tert. butyl acetate and isooctane it is possible to adjust the aggressivity of the medium and to talior an alternative simulant that interacts with the polymer in the same fashion as the EU's official fatty food simulants.
