The substance specified in the Annex, belonging to the additive category ‘nutritional additives’ and to the functional group ‘amino acids, their salts and analogues’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union .
ANNEX Identification number of the additive Name of the holder of authorisation Additive Composition, chemical formula, description, analytical method. Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation mg/kg of complete feed with a moisture content of 12 % Category of nutritional additives. Functional group: amino acids, their salts and analogues 3c306 — DL-methionyl-DL-methionine Additive composition Crystalline powder from chemical synthesis with a minimum of 93 % DL-methionyl-DL-methionine, a maximum of 3 % DL-methionine and a maximum of 3 % sodium sulphate (on a dry matter basis) Characterisation of the active substance DL-methionyl-DL-methionine (2-[(2-amino-4-methylsulfanylbutanoyl)amino]-4-methylsulfanylbutanoic acid) Chemical formula: C 10 H 20 N 2 O 3 S 2 CAS number: 52715-93-2 Analytical method ( 1 ) For the quantification of DL-methionyl-DL-methionine in the feed additive: reversed-phase high performance liquid chromatography coupled to photometric detection at 205 nm (RP-HPLC-UV). For the quantification of DL-methionyl-DL-methionine in premixtures, compound feed and feed materials: ion exchange chromatography coupled with post-column derivatisation and photometric detection at 570 nm (IEC-UV). Fish and crustaceans — The moisture content shall be indicated on the labelling. 9 September 2025 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: https://ec.europa.eu/jrc/en/eurl/feed-additives/evaluation-reports
