Scientific Opinion


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], methylallyl 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.
