E501: Potassium Carbonates
Main role: raising and acidity control
Also listed as: potassium carbonate, potassium bicarbonate
What is E501 (Potassium Carbonates)?
E501 covers potassium carbonate and potassium hydrogen carbonate. These alkaline salts are used to manage acidity and can participate in raising systems selected for a recipe.
What does it do in food?
Its main role is raising and acidity control. Mineral ingredients can adjust acidity, firm a food, or keep powders flowing. A technical mineral ingredient does not establish a nutritional dose; use the nutrition declaration to assess amounts per serving.
Food and formulation examples
- Baking preparations
- Cocoa processing
- Specialty noodle formulations
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 E501, E 501, or the ingredient name. Related names and label terms include potassium carbonate, potassium bicarbonate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Replacing a sodium salt with a potassium salt changes the mineral contribution. Anyone with a prescribed potassium restriction should consider the complete product and their clinician's dietary advice.
Is E501 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 E501 as Potassium carbonates. 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.
