| 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. |
| 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 flavouring substances from subgroup 1.1.4 of FGE.19 in the Flavouring Group Evaluation 203 Revision 2 (FGE.203Rev2). In FGE. 203 Revision 1, the Panel concluded that the genotoxic potential could not be ruled out for the flavouring substances in this FGE. |
| Carcinogenicity_EU_PPP | - | - | - | The EFSA Panel on Food Additives and Flavourings was requested to evaluate 29 flavouring substances attributed to the Flavouring Group Evaluation 70 (FGE.70), using the Procedure in Commission Regulation (EC) No 1565/2000. |
| 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 203 (FGE.203) concerns 17 substances. The 17 substances correspond to subgroup 1.1.4 of FGE.19. Twelve of these substances are alpha,beta-unsaturated aldehydes with two or more conjugated double bonds with and without additional non-conjugated double bonds [FL-no: 05.057, 05.064, 05.071, 05.084, 05.101, 05.108, 05.125, 05.127, 05.140, 05.141, 05.173 and 05.196] and five are precursors for such aldehydes [FL-no: 02.139, 02.153, 02.162, 02.188 and 09.573]. Based on the available data on carcinogenicity and genotoxicity there is a safety concern for hexa-2(trans),4(trans)-dienal [FL-no: 05.057] since a non-threshold mechanism cannot be excluded. This conclusion also applies to the other substances of this FGE. Therefore, the substances of this FGE cannot be evaluated through the Procedure. The Panel requests data which clarify whether the carcinogenic effects were based on a thresholded mechanism. |
