3c384 | L-isoleucine | Additive compositionPowder with a minimum content of L-isoleucine of 90 % (on a dry matter basis)Characterisation of the active substanceL-isoleucine produced by fermentation with Corynebacterium glutamicum KCCM 80185IUPAC name: (2S,3S)-2-amino-3-methylpentanoic acidChemical formula: C6H13NO2CAS number: 73-32-5Analytical methodFor the identification of L-isoleucine in the feed additive:- Food Chemical Codex "L-isoleucine monograph"
For the quantification of isoleucine in the feed additive:- ion-exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FLD) or
- ion-exchange chromatography coupled to post-column derivatisation and photometric detection (IEC-VIS)
For the quantification of isoleucine in premixtures:- ion-exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FLD) or
- ion-exchange chromatography coupled to post-column derivatisation and photometric detection (IEC-VIS) – Commission Regulation (EC) No 152/2009 (Annex III, F)
For the quantification of isoleucine in compound feed:- ion-exchange chromatography coupled to post-column derivatisation and photometric detection (IEC-VIS) – Regulation (EC) No 152/2009 (Annex III, F)
