EU feed-additive functional-group taxonomy (EU Reg 1831/2003 categories 1-4 + FFP group 5)

EU feed-additive functional-group taxonomy

Derived compilation of how the EU Feed Additives Register (EU Food & Feed Information Portal) classifies authorised feed additives by functional category and subcategory, aggregated from the landed FFP policy-items JSON.

Source dataset: pdf-raw/eu/eu_ffp_feed_additives_policy_items_2026-08-11.json — 1922 authorisation records (1914 categorised into EU Reg 1831/2003 categories 1-4 plus FFP group 5; 8 with a non-standard / unparsed functional-group code).

Functional categories (EU Reg 1831/2003 Annex I)

Category names are quoted from the consolidated regulation text (pdf-raw/eu/eurlex_32003R1831_consolidated_2026-08-11.html); the FFP feedCategoryFunctionalGroup codes are verbatim from the register JSON.

Non-standard functional-group codes

8 records carry a feedCategoryFunctionalGroup value that is not a clean category 1-5 code (e.g. rendering artifacts such as cat_func_group_800). They are excluded from the category tree above and listed honestly rather than forced into a category:

cat_func_group — Enterococcus faecium DSM 10663/NCIMB 10415
cat_func_group — 3-Phytase / EC 3.1.3.8 produced by Trichoderma reesei (CBS 528.94)
cat_func_group — Saccharomyces cerevisiae NCYC Sc 47
cat_func_group_800 — Endo-1,4-beta-xylanase / EC 3.2.1.8 produced by Trichoderma longibrachiatum (CNCM MA 6-10 W)
cat_func_group_820 — Saccharomyces cerevisiae NCYC Sc 47

cat_func_group — Preparation of endo-1,4-betaglucanase / EC 3.2.1.4, endo-1,3(4)-betaglucanase / EC 3.2.1.6 and endo-1,4-betaxylanase / EC 3.2.1.8 produced by Trichoderma longibrachiatum (ATCC 74 252)

Honest scope note

This is a derived compilation: the counts and the FFP codes are computed directly from the landed register JSON (pdf-raw/eu/eu_ffp_feed_additives_policy_items_2026-08-11.json); every sample additive name is a verbatim substring of that file.
EU Reg 1831/2003 defines four functional categories (1 Technological, 2 Sensory, 3 Nutritional, 4 Zootechnical). FFP surfaces coccidiostats/histomonostats as a separate group 5; these are placed under Zootechnical by the regulation, so group 5 is a descriptive FFP grouping, not an official 5th category.
Each authorisation record may carry multiple target-species / holder values; those dimensions are surfaced per-additive in the R4 additive-crosswalk topics, not here.
Authorisation status, expiry, and maximum levels are out of scope for this taxonomy view.
