Alternative fatty food simulants for migration testing of polymeric food contact materials

The amounts of substances migrating from plastics into high fat contents are in most cases higher than in foo contents. This increase in migration compared to water migration is not necessarily due to an increase in the diffusion coefficient due to interactions between the is often assumed. Ethanol is a good simulant for fatty has little interaction with many plastics, e.g. polyol readily soluble in it, and because it is easy to work utilizable limits of ethanol and ethanol/water mixture are developed from the physical background of diffusio ethanol and ethanol/water mixtures is supported by pub experimental migration results. ethanol/water mixtures as food simulants are developed from the physical background of diffusion. The use of ethanol and ethanol/water mixtures is supported by published experimental migration results.
