Scientific Opinion on Flavouring Group Evaluation 200, Revision 1 (FGE.200 Rev.1): 74 α,β‐unsaturated aliphatic aldehydes and precursors from chemical subgroup 1.1.1 of FGE.19

The Panel on Food Additives and Flavourings of the European Food Safety Authority was requested to evaluate the genotoxic potential of 74 flavouring substances from subgroup 1.1.1 of FGE.19 in the Flavouring Group Evaluation 200 Revision 1 (FGE.200 Rev1). In FGE.200, genotoxicity studies were provided for one representative substance, namely hex‐2(trans)‐enal [FL‐no: 05.073], and for other two substances in the same subgroup, namely 2‐dodecenal [FL‐no: 05.037] and 2‐nonenal [FL‐no: 05.171]. The Panel concluded that the concern still remains with respect to genotoxicity for the substances of this subgroup and requested an in vivo Comet assay performed in duodenum and liver for hex‐2(trans)‐enal [FL‐no: 05.073]. For the two other representative substances of subgroup 1.1.1 (nona‐2(trans),6(cis)‐dienal [FL‐no: 05.058] and oct‐2‐enal [FL‐no: 05.060]), the Panel requested a combined in vivo Comet assay and micronucleus assay. These data have been provided and are evaluated in the present opinion FGE.200 Rev1. Industry submitted genotoxicity studies on trans‐2‐octenal [FL‐no: 05.190], instead of oct‐2‐enal [FL‐no: 05.060]. Based on the available data, the Panel concluded that the concern for genotoxicity can be ruled out for hex‐2(trans)‐enal [FL‐no: 05.073], trans‐2‐octenal [FL‐no: 05.190] and nona‐2(trans),6(cis)‐dienal [FL‐no: 05.058], therefore all the 74 substances [FL‐no: 02.020, 02.049, 02.050, 02.090, 02.112, 02.137, 02.156, 02.192, 02.210, 02.231, 05.037, 05.058, 05.060, 05.070, 05.072, 05.073, 05.076, 05.078, 05.102, 05.109, 05.111, 05.114, 05.120, 05.144, 05.150, 05.171, 05.172, 05.179, 05.184, 05.189, 05.190, 05.191, 05.195, 06.025, 06.031, 06.072, 09.054, 09.097, 09.109, 09.119, 09.146, 09.233, 09.244, 09.247, 09.276, 09.277, 09.303, 09.312, 09.385, 09.394, 09.395, 09.396, 09.397, 09.398, 09.399, 09.400, 09.410, 09.411, 09.469, 09.482, 09.489, 09.492, 09.493, 09.498, 09.678, 09.701, 09.719, 09.741, 09.790, 09.841, 09.866, 09.947, 09.948, 13.004] can be evaluated through the Procedure for flavouring substances.
