| Carcinogenicity_EU_PPP | - | - | - | The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (the Panel) was asked to provide scientific advise for the Commission on the implications for human health of chemically defined flavouring substances used in or on foodstuffs in the Member States. In particular, the Panel was asked to evaluate flavouring substances using the Procedure as referred to in the Commission Regulation (EC) No 1565/2000. The present Flavouring Group Evaluation 210 (FGE.210) concerns 13 substances. The 13 substances correspond to subgroup 2.4 of FGE.19. Twelve of these substances are alpha,beta-unsaturated alicyclic ketones and one is a precursor for such ketones. |
| Carcinogenicity_EU_PPP | - | - | - | The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the European Food Safety Authority was requested to evaluate the genotoxic potential of 14 flavouring substances in Flavouring Group Evaluation 210 (FGE.210). |
| Carcinogenicity_EU_PPP | - | - | - | Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety of 31 compounds belonging to different chemical groups, when used as sensory additives in feed for all animal species. |
| Carcinogenicity_EU_PPP | - | - | - | Following a request from the European Commission, the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was asked to deliver a scientific opinion on the implications for human health of chemically defined flavouring substances used in or on foodstuffs in the Member States. In particular, the Panel was asked to evaluate flavouring substances using the Procedure as referred to in the Commission Regulation (EC) No 1565/2000. The Flavouring Group Evaluation 210 (FGE.210) concerned 13 substances, belonging to subgroup 2.4 of FGE.19. Twelve of these substances are alpha,beta-unsaturated alicyclic ketones and one substance is a precursor for such ketone. The genotoxicity concern with respect to the 13 alpha,beta-unsaturated alicyclic ketones and precursors in FGE.210 could not be ruled out based on the genotoxicity data and (Quantitative) Structure-Activity Relationship ((Q)SAR) predictions available. The present revision of FGE.210 (FGE.210Revision1) has been prepared due to additional genotoxicity data submitted by the Industry on representative substances ( [FL-no: 07.007], [FL-no: 07.061], [FL-no: 07.170] and [FL-no: 07.134]). Also an additional substance has been included, cis-1-(2,6,6-trimethyl-2-cyclohexen-1-yl)but-2-en-1-one [FL-no: 07.225]. |
