AU/NZ Australia & New Zealand (FSANZ)Permitted with conditionsFSANZ Schedule 15 lists potassium lactate for specified food categories and conditions. [FSANZ source]
EU European Union (EUR-Lex)Authorised with conditionsThe consolidated Union list includes E326 for specified categories and conditions of use. [EUR-Lex source]
US United States (FDA)Permitted with conditionsFDA 21 CFR §184.1639 affirms potassium lactate for specified functions at levels not exceeding current good manufacturing practice; it does not authorise use in infant foods or infant formula. [FDA source]

Goodnessly rates E326 Safe within its rating system. The rating does not remove the need to consider the product category, amount or full formulation.

📰Recent developmentsRegulator assessment checked 25 Sep 2026
  • JECFA’s assessment uses a not-limited ADI under intended food-use conditions.
  • No completed newer EFSA numerical ADI for potassium lactate was identified in the checked primary-source set.
  • The current EU Union list and FDA food-use provision were checked for identity and conditions.

This section is checked periodically rather than continuously — confirm the current primary source before relying on a regulatory detail.

Who might want to limit or avoid it
