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 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 224 (FGE.224), corresponding to subgroup 5.2 of FGE.19, concerns two α,β-unsaturated thiophenes. The two substances in the present evaluation are one α,β-unsaturated aldehyde and one α,β-unsaturated ketone, structures which are considered to be structural alerts for genotoxicity and the data on genotoxicity previously available for these two substances did not rule out the concern for genotoxicity.
The Panel did not find that genotoxicity data for either of the substances in subgroup 5.2 could be used for reading across to the other substance in the subgroup; therefore genotoxicity data have been requested for both substances, according to the test strategy worked out by the Panel.
The Flavour Industry has provided additional genotoxicity data for one 5-methyl-2-thiophenecarbaldehyde [FL-no: 15.004] of the two substances in FGE.224. The requested data for the other substance, 3-acetyl-2,5-dimethylthiophene [FL-no: 15.024], will be provided subsequently, according to the Flavour Industry.
Based on the data submitted the Panel concluded that 5-methyl-2-thiophenecarbaldehyde [FL-no: 15.004] does not give rise to concern with respect to genotoxicity and can accordingly be evaluated using the Procedure. For the other substance in subgroup 5.2, 3-acetyl-2,5-dimethylthiophene [FL-no: 15.024]., the requested genotoxicity data are still pending and no conclusion could be drawn in the present FGE.
