Choosing the right packaging!
Ensured by migration testing
Compliance with overall migration limit (OML)

Maximum legitimate residual content of the substance in the finished food contact material (QMA)
!!! Consideration of actual applied conditions
(time and temperature combinations)

currently, 28 parts are published within this standard Article 2 of 89/109/EEC:
Materials and articles must be manufactured in compliance with good manufacturing practice so that, under their normal or foreseeable conditions of use, they do not transfer their constituents to foodstuffs in quantities which
could:
endanger human health,
bring about an unacceptable change in the composition of the foodstuffs or a deterioration in the organoleptic characteristics thereof.

11. Selection of the right Simulant List of simulants:
Regulation 85/572/EEC
Example:
12. Migration Testing:
Unknown contact time, application for ambient temperature or lower temperatures:
10 d / 40 C (all simulants)
Unknown contact time & unknown application temperature:
4 h / 100 C bzw. Reflux (simulant A, B, C)2 h / 175 C (simulant D)
Hot filling (< 15 min at 70-100 C):
2 h / 70 C (all simulants)
Standardized Testing Conditions according to European Regulations / Austrian Plastics Regulation
13. Migration Testing Substitute test for fatty foods
If the use of fatty food simulants is not feasible for technical reasons
Substitution: defined test media and conditions,
corresponding to the simulant D
Iso-Octan
Ethanol (95 %)
Modified Polyphenylenoxid (Tenax)
14. Migration Testing Consideration of the practical usage conditions of the packaging (e. g. for which foodstuff applied?)
Clarification of the usage conditions
Selection of the simulant and test conditions
(contact time and temperature)
Is overall migration limit complied (OML)?
Compliance with thresholds of the specific migration (SML)
residual content in the commidity (QM)?

20. Chromatographic Separation
21. Definitions DECISION LIMIT: Threshold for the presence of an analyte (yes/no). If a sample possessed the exact content of the dicision limit, the analyte wouldnt be detected in 50 % of the measurements despite the presence of the analyte (false negative).
DETECTION LIMIT: minimal concentration of an analyte, which is detected with a high likeliness (e. g. 95 %). The detection limit is usually twice the amount of the decision limit.
DETERMINATION LIMIT: lowest concentration of an analyte, which can be quantitatively detected with a determined accuracy. Quantitative analyse results are only declared above the determination limit. The determination limit equals approximately the triple amount of the decision limit.
