L-脯氨酸 — 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
- 🇨🇳 CN — 公告2045
L-脯氨酸: L-脯氨酸 is listed in 表一 饲料添加剂品种目录 (category 氨基酸、氨基酸盐及其类似物); scope 养殖动物. _(src: CN 公告2045)_ - 🇪🇺 EU — Feed Additives Register
2b17019: L-Proline / CAS No. 147-85-3 / Flavis No. 17.019 — functional category2 b. 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 2b17019)_ - 🇺🇸 FDA (US) — EAFUS
147-85-3: L-PROLINE listed for FLAVOR ENHANCER where applicable; CAS 147-85-3. _(src: FDA EAFUS, CAS 147-85-3)_ - 🇺🇸 AAFCO (US) — Ch.6: No stand-alone AAFCO OP 2024 Ch.6 entry for this substance. AAFCO defines substances only where a corresponding feed ingredient is listed; where absent, the cell is an honest gap, not a claim of non-existence. _(src: AAFCO OP 2024 Ch.6 — gap)_
- 🇨🇦 CA — Feeds Regs 2024 (CFIT): L-Proline — is the product that contains a minimum of 97% 2-pyrrolidine carboxylic acid, and having the CAS# 147-85-3. It shall be labelled with a guarantee for minimum percent L-proline. _(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 L-脯氨酸 (scope 养殖动物). FDA EAFUS lists L-PROLINE (CAS 147-85-3, used for FLAVOR ENHANCER) as a food substance. AAFCO OP 2024 Ch.6 has no stand-alone entry for this substance (honest gap). 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)).
