E357: Potassium Adipate
Main role: acidity buffering
Also listed as: dipotassium adipate
What is E357 (Potassium Adipate)?
Potassium adipate is the potassium salt of adipic acid. Its food role concerns acidity and buffering in specified formulations. It differs from potassium citrate, potassium acetate, and other potassium-containing food ingredients.
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
- Specified dessert mixes
- Acidity-control 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 E357, E 357, or the ingredient name. Related names and label terms include dipotassium adipate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Potassium adipate on a label does not quantify potassium intake. Use the finished product's declared nutrients when a potassium restriction or mineral comparison matters.
Is E357 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 E357 as Potassium adipate. 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.
