What it is

Potassium carbonate is a potassium salt of carbonic acid. It is a white powder that can be produced from potassium hydroxide and carbon dioxide, or historically, from wood ashes. It is soluble in water and has a bitter taste.

Why it's used

Potassium carbonate is used as an acidity regulator, stabilizer, and leavening agent in foods. It helps control the pH of foods and can contribute to browning in baked goods. It is commonly found in noodles, baked goods, and some dried fruits.

Health notes

Potassium carbonate is generally recognized as safe (GRAS) by the FDA for use in food. It is an essential mineral for the body, playing a role in nerve function and fluid balance. International bodies like JECFA have evaluated potassium carbonate and established acceptable daily intake levels. At typical food intake levels, it is not associated with adverse health effects.

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