E354: Calcium Tartrate
Main role: acidity-related processing
Also listed as: calcium L-tartrate
What is E354 (Calcium Tartrate)?
Calcium tartrate is a calcium salt of tartaric acid. The food-additive identity is distinct from tartaric acid itself and from potassium hydrogen tartrate. It appears in specialized acidity-related processing applications.
What does it do in food?
Its main role is acidity-related processing. 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
- Specified acidity-control preparations
- Selected wine-processing contexts
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 E354, E 354, or the ingredient name. Related names and label terms include calcium L-tartrate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Match the exact tartrate form when checking a processing specification. A mineral name in the ingredient does not demonstrate that the food is a nutritionally significant calcium source.
Is E354 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 E354 as Calcium tartrate. 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.
