L-丙氨酸 — additive cross-jurisdiction identity

L-丙氨酸 — 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.

• Substance anchor: L-丙氨酸 (L-Alanine)
• Verdict: closest_with_differences

Per-jurisdiction entry

• 🇨🇳 CN — 公告2045 L-丙氨酸: L-丙氨酸 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 2b17002: L-Alanine / CAS No. 56-41-7 / Flavis No. 17.002 — functional category 2 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 2b17002)_
• 🇺🇸 FDA (US) — EAFUS 302-72-7: DL-ALANINE listed for FLAVORING AGENT OR ADJUVANT where applicable; CAS 302-72-7. _(src: FDA EAFUS, CAS 302-72-7)_
• 🇺🇸 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-Histidine monohydrochloride monohydrate (or glyoxaline-5-alanine) — is the crystalline monohydrochloride salt of alpha-amino-4(or 5)-imidazolepropionic acid, having the CAS# 5934-29-2. It is the purified product resulting from a fermentation process using the non-pathogenic strain Escherichia coli NITE SD 00268 (Escherichia coli KY23123). It contains a minimum of 98% crystalline L-histidine monohydrochloride monohydrate. To address worker safety concerns, it shall be labelled with the following statement: "This ingredient may cause respiratory irritation and/or sensitization. Appropriate respiratory protective equipment must be worn during handling. / Cet ingrédient peut causer une irritation et/ou une sensibilisation respiratoire. Un appareil de protection respiratoire approprié doit être porter lors de la manutention." It shall be labeled with guarantees for minimum percent L-histidine monohydrochloride monohydrate, minimum percent L-histidine, and maximum percent moisture. _(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-丙氨酸 (scope 养殖动物). FDA EAFUS lists DL-ALANINE (CAS 302-72-7, used for FLAVORING AGENT OR ADJUVANT) 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)).
