Abstract The Panel on Food Additives and Flavourings of the European Food Safety Authority was requested to evaluate the genotoxic potential of flavouring substances from subgroup 3.2 of FGE.19 in the Flavouring Group Evaluation 215, Revision 1 (FGE.215Rev1). In FGE.215, the Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids concluded that the concern for genotoxicity could not be ruled out and requested in vivo data for the two representative substances 4-phenylbut-3-en-2-one [FL-no: 07.024] and 1-(4-methoxyphenyl)pent-1-en-3-one [FL-no: 07.030]. The Flavour Industry has provided additional genotoxicity studies for both representative substances [FL-no: 07.024] and [FL-no: 07.030]. Based on these new data, the Panel concluded that the concern for genotoxicity is ruled out for the representative substance [FL-no: 07.024] and for the structurally related substances 4-phenylbut-3-en-2-ol [FL-no: 02.066] and 3-methyl-4-phenylbut-3-en-2-one [FL-no: 07.027] which can accordingly be evaluated through the Procedure in FGE.69. For the representative substance 1-(4-methoxyphenyl)pent-1-en-3-one [FL-no: 07.030], the Panel concluded that [FL-no: 07.030] is aneugenic in vitro. For such substances, there is currently no agreed follow-up strategy to finalise their safety assessment. The Panel is aware that the EFSA Scientific Committee is going to address this issue and a statement clarifying the assessment of in vitro aneugenic substances is under preparation. The Panel concluded therefore that, for the time being, the representative substance 1-(4-methoxyphenyl)pent-1-en-3-one [FL-no: 07.030] and the structurally related substances vanillylidene acetone [FL-no: 07.046] and 1-(4-methoxyphenyl)-4-methylpent-1-en-3-one [FL-no: 07.049] cannot be evaluated through the Procedure. The Panel further concluded that 4-(2,3,6-trimethylphenyl)but-3-en-2-one [FL-no: 07.206] is to be considered as a stand-alone substance due to the presence of the methyl groups, therefore, in vitro genotoxicity data were requested for [FL-no: 07.206]. Industry communicated that the evaluation of [FL-no: 07.206] is not supported any longer, therefore additional data were not submitted.
