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 a feed additive, 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 additive/kg of complete feed with a moisture content of 12 % Category of nutritional additives. Functional group: amino acids, their salts and analogues. 3c371i - L-valine Additive composition: Powder with a minimum content of L-valine of 98 % (on a dry matter basis) and a maximum content of 1,5 % water All species - - - 1. L-valine may be placed on the market and used as an additive consisting of a preparation. 2. The additive may be used via water for drinking. 3. In the directions for use of the additive and premixture, the storage conditions, the stability to heat treatment and the stability in water for drinking shall be indicated. 4. The label of the additive and premixture shall indicate the following: ‘The supplementation with L-valine, in particular via water for drinking, should take into account all essential and conditionally essential amino acids in order to avoid imbalances.’ 5. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address the potential risks by inhalation, eye or dermal contact. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment, including breathing protection, safety glasses and gloves. 23.5.2031 Characterisation of the active substance: L-valine ((2S)-2-amino-3-methylbutanoic acid) produced by Corynebacterium glutamicum CGMCC 7.358 Chemical formula: C 5 H 11 NO 2 CAS number: 72-18-4 Analytical method ( 1 ) : For the identification of L-valine in the feed additive: — Food Chemical Codex "L-valine monograph" For the quantification of valine in the feed additive: — ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS) For the quantification of valine in premixtures, feed materials and compound feed: — ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS) – Commission Regulation (EC) No 152/2009 (Annex III, F) For the quantification of valine in water: — ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FD) ( 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
