Regulatory status
USA — Allowed
GRAS as a direct food substance under 21 CFR 182.6285, usable at good manufacturing practice levels with no other quantitative limit. Source (2026-07-23)
EU — Restricted
Authorised under Regulation (EC) No 1333/2008, Annex II, as part of the E 340 potassium phosphates group and the wider phosphates family (E 338–341, E 343, E 450–452), subject to defined maximum permitted levels by food category. Source (2026-07-23)
Regulatory status by region
FDA's GRAS listing imposes no numeric usage ceiling beyond GMP, unlike the EU's category-specific maximum permitted levels.
EFSA's 2019 re-evaluation set a group ADI of 40 mg/kg body weight/day (as phosphorus) for the phosphates family, and the EU enforces explicit per-category maximum levels under Annex II — a stricter numeric regime than the FDA's GMP-only standard.
