| Carcinogenicity_EU_PPP | - | - | - | The Panel on Food Additives and Flavourings (FAF Panel) of the European Food Safety Authority was requested to evaluate the genotoxic potential of the flavouring substances from subgroup 1.2.1 of FGE.19 in the Flavouring Group Evaluation 204 (FGE.204). |
| Carcinogenicity_EU_PPP | - | - | - | The European Commission requests EFSA to carry out a safety assessment on the substances oct-1-en-3-ol, pent-1-en-3-ol, hex-1-en-3-ol, dec-1-en-3-ol, 1-hepten-3-ol, oct-1-en-3-one, pent-1-en-3-one, oct-1-en-3-yl acetate and oct-1-en-3-yl butyrate [FL-no: 02.023, 02.099, 02.104, 02.136, 02.155, 07.081, 07.102, 09.281 and 09.282], evaluated in FGE.205 Revision 1, in accordance with Commission Regulation (EC) No 1565/2000. |
| Carcinogenicity_EU_PPP | - | - | - | The European Food Safety Authority (EFSA) asked the Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (the Panel) to provide scientific advice to 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 requested to consider the Joint FAO/WHO Expert Committee on Food Additives (the JECFA) evaluations of flavouring substances assessed since 2000, and to decide whether no further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. These flavouring substances are listed in the Register, which was adopted by Commission Decision 1999/217/EC and its consecutive amendments. The present Flavouring Group Evaluation 204 (FGE.204), corresponding to subgroup 1.2.1 of FGE.19, concerns 16 mono-unsaturated, aliphatic, alpha,beta-unsaturated ketones and two precursors for such ketones. The alpha,beta-unsaturated aldehyde and ketone structures are structural alerts for genotoxicity and the data on genotoxicity previously available did not rule out the concern for genotoxicity for these 18 flavouring substances. |
| Carcinogenicity_EU_PPP | - | - | - | Following a request from the European Commission the Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) was asked to deliver a scientific opinion to provide scientific advice to 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 requested to consider the Joint FAO/WHO Expert Committee on Food Additives (the JECFA) evaluations of flavouring substances assessed since 2000, and to decide whether no further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. These flavouring substances are listed in the Register, which was adopted by Commission Decision 1999/217/EC and its consecutive amendments. In Flavouring Group Evaluation 63, Revision 1 (FGE.63Rev1) the EFSA considered 19 flavouring substances from two groups of flavouring substances consisting of aliphatic secondary alcohols, ketones and related esters evaluated by the JECFA at its 59th meeting and at its 69th meeting. The present revision of FGE.63, FGE.63Rev2, includes the consideration of one additional substance, 4-methylpent-3-en-2-one [FL-no: 07.101]. This substance [FL-no: 07.101] was evaluated by the JECFA at its 59th meeting and the substance is an alpha,beta-unsaturated ketone originally allocated to and evaluated in FGE.204 in which it was considered not to be of concern with respect to genotoxicity. Therefore, the present revision of FGE.63, FGE.63Rev2, considers 20 flavouring substances evaluated by the JECFA. The Panel concluded that the 20 substances in the JECFA flavouring group of aliphatic secondary alcohols, ketones and related esters are structurally related to the group of 49 saturated and unsaturated aliphatic secondary alcohols, ketones and esters of secondary alcohols and saturated linear or branched-chain carboxylic acids evaluated in FGE.07Rev4. |
