Final conference FP7 RTD project FACET (Flavours, Additives and food Contact materials Exposure Tool) 26th October 2012 Brussels, Belgium

The FP7 RTD project FACET (Flavours, Additives and food Contact materials Exposure Tool) project is now completed. Its achievement are presented to its stakeholders. The event is taking place on Friday 26th October in Brussels. The concept behind this project is the creation of a food chemical exposure system, sustainable beyond the project life, which covers representative regions of the EU and which will meet, to the highest possible standard, the needs of the EU regulatory authorities in the protection of consumer health. The achievements of the project were: To record occurrence levels of targeted chemicals in representative regions of the EU food supply. To create a database of targeted food chemical concentrations in foods. To establish a migration modeling framework for complex packaging materials into foods under real conditions of use to deliver realistic concentration estimates for consumer exposure modeling. To construct a tiered food intake database aimed at foods which are relevant to the target food chemicals. The database is tiered from very comprehensive data to less detailed data to reflect the existing variability in the access to, and level of detail in, food intake data. To develop a PC based, publicly available software programme, taking into account the variation of national food consumption data, which draws on limited data, built on known laws governing food intake and in particular built on small national surveys and local knowledge to model regional intake of target foods. To build new databases, populated with the data generated by the project to provide estimates of exposure using the probabilistic model.JRC.I.1 - Chemical Assessment and Testin

Development of a harmonised method for specific migration into the new simulant for dry foods established in Regulation 10/2011: Establishment of precision criteria from an EU interlaboratory comparison organized by the EURL- Food Contact Materials for the quantification from and migration into poly(2,6-diphenyl phenylene oxide)

This report presents the results of the EU Interlaboratoy comparison (ILC) of the EURL-FCM,towards validation criteria for the using the new simulant for specific migration into dry foods, poly(2,6-diphenyl phenylene oxide), PPPO. Regulation EU 10/2011 has established PPPO as new simulant for testing compliance of plastics in contact with foods. The enforceability of the Regulation required the validation of a method effectively to measure the quantifiaciton of a range of substances to use as models into PPPO as well as the validation of the migration test for long term storage which is typical for dry foods. This was accomplished under the work programme of the EURLwith 16 volunteer National Reference Laboratories (NRLs). The laboratories performance were successful with more than 8 valid results, even taking into account the complexity of the exercise. Considering the lack of the data previously available in the literature, this interlaboratory comparison exercise provided the first successful attempt to derive precision data at EU level for a specific migration experiment. It also represented a worst case and was very extensive with 3 levels of concentrations and 1 film, 5 substances, 4 replicates and 17 labs, i.e 1360 data points. This exercise consequently provided a great breadth of valuable detailed and traceable precision data, which could be used for a more refined validation of the method and proficiency test of official controls planned for 2013.JRC.I.1-Chemical Assessment and Testin

Effect of Concentration and Relative Humidity on the Transfer of Alkan-2-ones through Paper Coated with Wheat Gluten

International audienceThe transport properties of two methyl ketones, 2-heptanone and 2-nonanone, through a paper coated with a wheat gluten (WG) solution were studied as a function of aroma compound concentration differential and relative humidity. Whatever the conditions, coating improved the aroma barrier properties of the paper. Whereas permeability of 2-nonanone through WG coated paper was not affected by the concentration differential, a high concentration of 2-heptanone induced a permeability increase, which can be explained by a slight plasticization effect of this compound. The moisture content of the films markedly affected the barrier properties depending on the aroma compound. For 2-heptanone, the most polar compound, the increase of permeability with relative humidity was related to the increase of diffusivity and solubility coefficient of this compound. With 2-nonanone, permeability and diffusivity coefficients strongly decreased with the increase of moisture content. This decrease could be linked to the hindrance in diffusivity of the less polar compound induced by the presence of water molecules. The different behavior in permeation properties seems to be related to the hydrophobic nature of the aroma compound. At intermediate and high humidity levels, coated papers are found to have better aroma barrier properties than LDPE films
