Test for "Overall migration (OML), Sensory analysis, colour fastness, microbiology"
Inertness and organolpetics of food contact materials (FCM)
Determination of overall migration according to Regulation (EU) No. 10/2011 and the standard series EN 1186 the sensory suitability with food simulants. Determination of the colour-transmission of coloured materials (bleeding).
overall migration acc. Reg. (EU) No 10/2011 standardized testing conditions (OM1- OM7)
Regulation (EU) No. 10/ 2011 (PIM)/ DIN EN 1186 classical food simulants (not alternative tests like Isooctane testing):
A= Ethanol 10 % (v/v), B= Acetic acid 3 % (w/v), C= Ethanol 20 % (v/v), D1= Ethanol 50 % (v/v), D 2= Vegetable oil, E= poly(2,6-diphenyl-p-phenylene oxide) (Tenax ®)
Organoleptic analysis of packaging materials/ sensory analysis
Organoleptic determination of the odour and off- flavour (taint) transfer from packaging material to standardised test foodstuffs. Generally known as "Robinson" test.
overall migration rapid tests and alternative simulants
Food simulant substitutes according to Reg EU 10/2011: To screen for overall migration food simulants can be replaced if based on scientific evidence the substitute food simulants overestimate migration compared to the regulated food simulants.
Rapid tests are carried out by usage of solvents like Isooctane (for testing of non polar materials e.g. polyolefines) or Ethanol 95% (for testing of polar materials like e.g. PET).
overall migration special tests / Substitute test OM8 und OM9
Test conditions free configurable according DIN EN 1186, classical food simulants (exceptionally alternative tests like Isooctane or 95 Vol.-% Ethanol testing):
water, A= Ethanol 10 % (v/v), B= Acetic acid 3 % (w/v), C= Ethanol 20 % (v/v), D1= Ethanol 50 % (v/v), D 2= Vegetable oil, E= poly(2,6-diphenyl-p-phenylene oxide) (Tenax ®)
Substitute test for OM7 with food simulant D2: OM8 und OM9 acc. Resolution (EC) 10/2011
colourfastness of dyes of plastic materials
Acc. to the 24th Communication on the testing of plastics, Bundesgesundheitsblatt 15 (1972) "(...) There are no objections to the use of colorants for coloring plastics and other polymers 2 in the manufacture of commodities (...), provided (...) the requirement of no visible migration to food stuffs during proper use of the commodity (...)." This requirement can be easily checked with the test available here.
Determination of total viabl count, yeasts and moulds resp. enterobacteria
Determination of migration test temperature (SML and OM) for microwave application
Tests of specific migration (SML) and overall migration (OM) on plastic articles which are intended for use in microwave ovens,in accordance with EN 1186-1 are performed under the appropriate time and temperature conditions in a conventional oven. For this purpose the temperature that occurs at the interface of food / packaging during heating of the contents under the conditions of use in the worst foreseeable conditions must be determined. This is done by using a calibrated microwave oven at the predetermined heat output.
