E326 / Antioxidants & acidity regulators

Potassium lactate

Selected sources checked · Scope & sources

Safety in brief

Safe

Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.

Watch for
No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
Our advice
Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is

Potassium lactate is the potassium salt of lactic acid, used as a preservative and flavor enhancer in meats, dairy, and bakery products to extend shelf life and reduce bacterial growth. It is also used in cosmetics as a moisturizer and pH stabilizer, and in medical solutions for treating acidosis. It is considered safe for food use at typical levels.

Also appears on labels as: Potassium lactate, Lactic acid potassium salt, K-lactate, Food grade potassium lactate, E326, E 326, E-326, INS 326, Potassium D-lactate, Potassium L-lactate, Additivo alimentare E326, Additif alimentaire E326.

Country rules

Country checks for E326

Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.

MarketWhat is checked
European Union

Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E326: Potassium lactate.

Listing alone does not allow every food use. Part E food categories, limits, specifications and applicable later acts still need a product-specific check. Source read: .

Great Britain

The FSA register record for E326 (Potassium lactate) lists “Authorised” in England, Scotland and Wales.

Register updated: 01 April 2025; record checked: . Food-specific conditions and specifications still need a separate legal check.

Food uses, limits and exceptions

Named preparation and use conditions

The section lists specified potassium lactate under good manufacturing practice for flavouring, humectant and pH-control functions. It expressly does not authorise use in infant foods or infant formulas. Conditions for sodium or calcium lactate must be checked separately.

21 CFR 184.1639 · 21 CFR 184.1

EatMatrix’s reading: a legal use condition answers where and how an ingredient may be used. It is not a test of your product, a personal safe intake or a claim that the ingredient benefits your body. Match the named substance, food and amount. Other federal provisions, food standards, state rules and later changes may also apply; this is a selected source review, not a complete product-compliance decision.

Northern Ireland

Review pending. Check the applicable EU rules and territory arrangements; the GB register alone does not establish this status. FSA guidance is a starting source, not a verified permission for this entry.

Canada

Named food-use records located. Health Canada lists the preparations below for specified foods and purposes. This is conditional permission for those uses, not approval of every product or a personal safety verdict.

Only the named records and conditions below were located. Exact composition and specifications still need matching.

Source tables captured . List publication dates are shown separately. Good Manufacturing Practice (GMP) is a condition of use, not an unlimited amount or a recommended intake.

Food and Drug Regulations B.16.003 requires the listed source, purpose, amount and other conditions to match. The official consolidation read was current to 21 September 2026; product specifications and applicable later changes still need checking.
