COMMISSION IMPLEMENTING REGUL ATION (EU) 2020/1764 
of 25 November 2020 
concer ning the author isation of disodium 5'-inosinate produced by fermenta tion with 
Cor ynebacter ium stationis KCCM 80161 as a feed additiv e for all animal species 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Havi ng regar d to the Treaty on the Functioning of the European Union, 
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1) Regulation (EC) No 1831/2003 provid es for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such author isation. 
(2) In accordance with Article 7 of Regulation (EC) No 1831/2003, an application was submitted for the author isation 
of disodium 5'-inosinate produced by fermentation with Corynebacter ium stationis KCCM 80161. This application 
was accompanied by the particulars and documents required under Article 7(3) of Regulation (EC) No 1831/2003. 
(3) This application concer ns the author isation of disodium 5'-inosinat e produced by fermentation with Corynebacter ium 
stationis KCCM 80161 as a feed additive for all animal species. The applicant requested this additive to be classif ied in 
the additive cate gory ‘sensor y additives’. 
(4) The applicant request ed the feed additive to be author ised for use also in wate r for drinking. Howe ver, Regulation 
(EC) No 1831/2003 does not allow the author isation of ‘flavouring compo unds ’ for use in water for drinking. 
Theref ore, the use of disodium 5'‐inosinat e produced by fermentation with Corynebacter ium stationis KCCM 80161 in 
water for drinking should not be allowe d. The fact that the additive is not author ised for use as a flavouring in wate r 
for drinking does not preclude its use in compo und feed administ ered via water . 
(5) The European Food Safety Author ity (‘the Author ity’) concluded in its opinion of 7 May 2020 (2) that, under the 
proposed conditions of use, disodium 5'‐inosinate produced by fermentation with Corynebacter ium stationis KCCM 
80161 does not have adverse effects on animal health, consumer health or the environment. The Author ity 
concluded in the opinion that the additive is not toxic by inhalation, not irritant to skin or eyes and is not a dermal 
sensitiser . The Authority also concluded that the effect of disodium 5'-inosinate produced by fermentation with 
Corynebacter ium stationis KCCM 80161 to increase the taste of food is well proven , and theref ore, no further 
demonstration of its efficacy in feed is necessar y. The Author ity does not consider that there is a need for specifi c 
requirements of post-market monitori ng. It also verified the repor t on the method of analysis of the feed additives 
in feed submitte d by the Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(6) The assessment of disodium 5'-inosinate produced by fermentation with Corynebacter ium stationis KCCM 80161 
shows that the conditions for author isation, as provid ed for in Article 5 of Regulation (EC) No 1831/2003, are 
satisfied. According ly, the use of disodium 5'-inosinat e produced by fermentation with Corynebacter ium stationis 
KCCM 80161 should be author ised as specifi ed in the Annex to this Regulation. 
(7) Restr ictions and conditions should be provid ed for to allow better control. In particular , a recommended content 
should be indicated on the label of the feed additive. Where such content is exceeded, certain information should be 
indicated on the label of premixtures. 
(8) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,

Article 1 
The substance specified in the Annex, belonging to the additive cate gory ‘sensor y additives’ and to the functional group 
‘flavouring compo unds ’, is author ised as a feed additive in animal nutr ition subject to the conditions laid down in that 
Annex. 
Article 2 
This Regulation shall enter into force on the twentieth day followi ng that of its publication in the Official Journal of the 
European Union. 
This Regulation shall be binding in its entirety and directly applicable in all Member States.
