核黄素（维生素 B2） — additive cross-jurisdiction identity

核黄素（维生素 B2） — additive cross-jurisdiction identity

Derived crosswalk of how one feed additive is named and authorised across jurisdictions. No claim of regulatory equivalence is made — pairings are anchored on the substance identity, and the verdict states where the definitions actually diverge.

Per-jurisdiction entry

• 🇪🇺 EU — Feed Additives Register 3a825V: riboflavin (vitamin B2) — functional category 3 a. Authorised in the EU feed additives register (first-hand-derived parse of the EU Food & Feed Information Portal register). Cross-jurisdiction note: this EU authorisation is quoted from the register and is not asserted to be equivalent to the CN 公告 2045 / FDA EAFUS entries (definitions, chemical form, or conditions of use may differ). _(src: EU Food & Feed Information Portal feed-additives register; parsed dataset pdf-parsed/eu_feed_additives_2023_1813.json, e_number 3a825V)_

• 🇨🇦 CA — Feeds Regs 2024 (CFIT): Riboflavin — is 7,8-dimethyl-10-(D-ribo-2,3,4,5-tetrahydroxypentyl) isoalloxazine, generally expressed as C17H20N4O6, and having the CAS# 83-88-5. It may be blended with suitable carriers listed in the Canadian Feed Ingredients Table to standardize the riboflavin concentration. If a carrier is used, it must be approved for use in livestock feeds, it shall be used at the approved rate, and the common name or names shall be indicated on the label. If an antioxidant is used, it must be approved for use in livestock feeds, it shall be used at the approved rate, and the common name or names shall be indicated on the label. If a preservative is used, it must be approved for use in livestock feeds, it shall be used at the approved rate, and the common name or names shall be indicated on the label. It shall be labelled with a guarantee for minimum milligrams of riboflavin per kilogram. _(src: Canadian Feed Ingredients Table (CFIT), inspection.canada.ca; SOR/2024-132; feed additive listed under Part 1 > Class 5.

Crosswalk verdict

CN 公告2045 lists 核黄素（维生素 B2） (scope 养殖动物). FDA EAFUS lists RIBOFLAVIN (CAS 83-88-5, used for COLOR OR COLORING ADJUNCT, 21 CFR 73.450) as a food substance. AAFCO OP 2024 Ch.6 defines Riboflavin Supplement (code 90.13). Verdict: CN↔US diverge in chemical form or regulatory framing; the pairing is the closest available US analogue, not a confirmed regulatory equivalence (EU filled from the EU Feed Additives Register (FFP parsed dataset)).

Recall mentions

_Derived from the in-repo recall datasets (RASFF 257 notifications, FDA CVM 58 pet-food recalls, FDA enforcement 186 general-food recalls). These are mentions of the additive name in recall records — mention ≠ causation: a recall citing the additive by name does not mean the additive itself was the hazard (the FDA enforcement set spans human food too). Each line is a verbatim substring of the cited recall source._
