What it is

Potassium carbonate is a white powder or crystalline solid. It is a salt derived from potassium and carbonate. It is often produced industrially through chemical processes, but can also be found naturally in some plants.

Why it's used

Manufacturers use potassium carbonate as an acidity regulator and leavening agent. It helps control the pH of foods and can contribute to the rise of baked goods. It is commonly found in cocoa processing, chocolate products, and some baked goods.

Health notes

Potassium carbonate is generally recognized as safe (GRAS) by the FDA when used as a food additive. It is used in small amounts in food, and typical dietary intake is not associated with adverse health effects. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated potassium carbonate and established acceptable intake levels.

Allergen info

Potassium carbonate is not derived from any of the 9 FDA major allergens. It does not contain gluten.
