E335: Sodium Tartrates
Main role: acidity buffering
Also listed as: sodium tartrate, disodium tartrate, sodium hydrogen tartrate
What is E335 (Sodium Tartrates)?
E335 covers sodium salts of tartaric acid used to control acidity in food systems. The mono- and disodium forms can differ in buffering behavior. A tartrate family name should therefore be read alongside the exact ingredient specification.
What does it do in food?
Its main role is acidity buffering. Acidity regulators adjust or buffer pH. The resulting acidity depends on the whole recipe, not just the presence of one acid or salt. Acidity control may also affect texture and the performance of other ingredients.
Food and formulation examples
- Acidity-control blends
- Selected confectionery
- Beverage preparations
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E335, E 335, or the ingredient name. Related names and label terms include sodium tartrate, disodium tartrate, sodium hydrogen tartrate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Sodium tartrate is not sodium citrate E331. Both can buffer a recipe, but the acid family and specified use are different.
Is E335 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E335 as Sodium tartrates. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
