E503: Ammonium Carbonates
Main role: raising
Also listed as: baker's ammonia, ammonium bicarbonate, ammonium carbonate
What is E503 (Ammonium Carbonates)?
Ammonium carbonates are raising agents that release gases during heating. Ammonium hydrogen carbonate is used particularly where a thin, low-moisture baked product lets those gases escape.
What does it do in food?
Its main role is raising. 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
- Thin biscuits
- Crackers
- Traditional crisp baked goods
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 E503, E 503, or the ingredient name. Related names and label terms include baker's ammonia, ammonium bicarbonate, ammonium carbonate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Baker's ammonia needs an appropriate recipe and thorough baking. It is not interchangeable spoon-for-spoon with baking soda in a thick or moist cake.
Is E503 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 E503 as Ammonium 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.
