Food categories and simulants

Overview of the food categories and simulants in the regulation 10/2011 (PIM)

Food Properties:	Food simulant:
Hydrophilic	(A) Ethanol 10 % (v/v)
Hydrophilic; < pH 4,5	(B) Acetic acid 3% (w/v)
Hydrophilic/Lipophilic; alcohol content up to 20 %	(C) Ethanol 20 % (v/v)
Lipophilic; alcohol content >20 %; oil in water emulsion	(D1) Ethanol 50 % (v/v)
Lipophilic; free fats	(D2) Vegetable oil with specific fatty acid distribution
Dry foods	(E) Poly-2,6-diphenyl-p-phenylene oxide (MPPO)

Thanks to the flexibility and modular structure of the Siegwerk (Sieg-Mi-Flex) migration cell system, many packaging sizes and thicknesses with a wide range of material properties can be used for migration tests with all liquid and solid food simulants, food simulants for substitute tests (iso-octane, ethanol 95 (v/v)) or solvents from pharmaceutical formulations, even above their boiling point, on a defined sample area plus subsequent storage depending on the time and temperature.

The Siegwerk (Sieg-Mi-Flex) migration cell system, in conformity with European Norm EN 1186-1:2002 (D), Appendix C (informative), Figure C.4 Cell type B and Figure C.5 Cell type C has been developed and tested in cooperation with the analytical department at Siegwerk Druckfarben AG & Co. KGaA.

Eva Holster and Dr Dieter Franke from Siegwerk Druckfarben AG & Co. KGaA: “The Siegwerk (Sieg-Mi-Flex) migration cell system not only facilitates sample preparation but is also the system with the greatest impermeability.”
