Preservatives
Sodium lactate
Definition
What it is
Sodium salt of lactic acid, used as a humectant and preservative. Often corn-derived. Relevant for corn-sensitive individuals.
On the label
Label names covered by this flag
- sodium lactate
- e325
Regulation
Regulatory status
No bans or restrictions are recorded for this ingredient in the jurisdictions clearlabel tracks (US, EU, UK, Canada, Japan, Australia/NZ, Brazil).
Explainer
In plain language
Sodium lactate is the sodium salt of lactic acid. In food it works as a humectant, meaning it holds moisture, and as a mild preservative that slows the growth of some bacteria. It is often produced by fermenting sugars from corn, though other starch sources can be used. It is common in deli meats and prepared foods where shelf life and moisture matter.
Assessment
Why it is flagged
Sodium lactate is broadly permitted and sits low on the severity scale, so this flag is mostly about transparency. The FDA lists it as an approved food ingredient, and in the EU it appears as E325. Clear Label surfaces it for two practical reasons. First, it is often corn-derived, which matters to people who track corn sensitivity, and the label rarely states the source. Second, it adds sodium, which some users prefer to watch across their overall diet. There is no established general health concern at normal food levels.
In the aisle
Where it commonly shows up
- Deli meats and packaged sliced meats
- Hot dogs and sausages
- Rotisserie-style and pre-cooked poultry
- Prepared refrigerated meals
- Some cheeses and dips
Practical
Reading the label
Sodium lactate is declared by name on US labels and as E325 in the EU. The label almost never says what the lactic acid was fermented from, so corn-sensitive shoppers cannot tell the source from the ingredient list alone.
Alternatives
If you want to avoid it
Some people who avoid corn-derived additives choose freshly sliced meats from a counter or products with shorter ingredient lists. Comparing two similar packages side by side often reveals a version without added lactate salts.
FAQ
Common questions
Is sodium lactate the same as MSG?
No. Sodium lactate is a salt of lactic acid used for moisture and mild preservation. Monosodium glutamate is a different compound used for savory flavor.
Is sodium lactate made from dairy?
Usually not. Despite the name, the lactic acid in commercial sodium lactate is typically made by fermenting plant sugars, often from corn, rather than from milk.
Why would a corn-sensitive person watch for it?
Because it is frequently corn-derived and the label rarely states the source. Logging products that contain it is one way to test whether it tracks with any personal pattern.
