Flavouring Group Evaluation 8, Revision 1 (FGE.08Rev1): Aliphatic and alicyclic mono-, di-, tri-, and polysulphides with or without additional oxygenated functional groups from chemical groups 20 and 30

Safety and efficacy of 8-mercapto-p-menthan-3-one and p-menth-1-ene-8-thiol belonging to chemical group 20 when used as flavourings for all animal species

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of two compounds belonging to chemical group 20 (aliphatic and aromatic mono- and di-thiols and mono-, di-, tri-, and polysulfides with or without additional oxygenated functional groups). 8-Mercapto-p-menthan-3-one [12.038] and p-menth-1-ene-8-thiol [12.085] are currently authorised as flavours in food. The FEEDAP Panel concludes that the two compounds are safe for the target species at the proposed maximum use level (0.05 mg/kg complete feed). No safety concern would arise for the consumer from the use of 8-mercapto-p-menthan-3-one and p-menth-1-ene-8-thiol up to the highest safe level in feedingstuffs for all animal species. Both compounds should be considered as irritants to skin and eyes, and 8-mercapto-p-menthan-3-one [12.038] also as irritant to the respiratory tract. No conclusions can be drawn on skin sensitisation potential. No environmental risk is foreseen for these compounds at the maximum proposed use level in feed. Since the two compounds are used as flavourings in food and their function is essentially the same as that in food, no further demonstration of efficacy is necessary.

Scientific Opinion on Flavouring Group Evaluation 74, Revision 4 (FGE.74Rev4): Consideration of aliphatic sulphides and thiols evaluated by JECFA (53rd and 61st meeting) structurally related to aliphatic and alicyclic mono-, di-, tri- and polysulphides with or without additional oxygenated functional groups from chemical group 20 evaluated by EFSA in FGE.08Rev5

The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids of the European Food Safety Authority was requested to consider evaluations of flavouring substances assessed since 2000 by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (EC) No 1565/2000. The present revision of this FGE is on the assessment of recently submitted toxicity data on methyl propyl trisulfide [FL‐no: 12.020], being the representative for a group of seven additional flavouring substances: diallyl trisulfide [FL‐no: 12.009], dimethyl trisulfide [FL‐no: 12.013], dipropyl trisulfide [FL‐no: 12.023], methyl allyl trisulfide [FL‐no: 12.045], diallyl polysulfides [FL‐no: 12.074], methyl ethyl trisulfide [FL‐no: 12.155] and diisopropyl trisulphide [FL‐no: 12.280]. Specifications have been provided for all substances. The Panel decided that the 90‐day study submitted for [FL‐no: 12.020] can be considered only once it is clearly demonstrated that the material tested is representative of the material of commerce and that potential reaction products of the components are not of safety concern. Therefore, no conclusion on the safety of the eight flavouring substances [FL‐no: 12.009, 12.013, 12.020, 12.023, 12.045, 12.074, 12.155 and 12.280] can be reached. For 2‐methyl‐4‐oxopentane‐2‐thiol [FL‐no: 12.169] and 2‐mercapto‐2‐methylpentan‐1‐ol [FL‐no: 12.241], additional subchronic toxicity data are required. The remaining nine substances [FL‐no: 12.088, 12.179, 12.198, 12.212, 12.238, 12.239, 12.255, 12.257 and 12.291] in this FGE are not considered of safety concern under the intended conditions of use.
