What it is

E 500 is the European designation for sodium carbonate, also known as soda ash. It is a salt derived from carbonic acid and sodium. Sodium carbonate can be found naturally in mineral deposits or produced industrially.

Why it's used

In food, E 500 functions as an acidity regulator and leavening agent. It helps control the pH of foods and reacts with acidic ingredients to produce carbon dioxide gas, causing doughs and batters to rise. It is commonly found in baked goods like cookies, cakes, and crackers.

Health notes

In the US, sodium carbonate is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. It is a common mineral salt and is not associated with adverse health effects at the levels typically found in food. E 500 has been evaluated by international bodies like JECFA and EFSA, which have assessed its safety.

Allergen info

Not a major allergen. It does not contain gluten.
