β,β胡萝卜素-4,4-二酮（斑蝥黄） — 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.

Crosswalk verdict

CN 公告2045 lists β,β胡萝卜素-4,4-二酮（斑蝥黄） (scope 家禽). FDA EAFUS lists CANTHAXANTHIN (CAS 514-78-3, used for COLOR OR COLORING ADJUNCT, 21 CFR 73.1075) as a food substance. AAFCO OP 2024 Ch.6 defines Canthaxanthin (code 87.115). 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)).
