What it is

Potassium bicarbonate is a white, crystalline powder that is a salt of potassium and bicarbonate. It occurs naturally in plants and is also produced commercially through chemical processes. It is soluble in water.

Why it's used

Manufacturers use potassium bicarbonate as an acidity regulator and leavening agent. It helps control the pH of foods and can react with acids to produce carbon dioxide gas, causing doughs to rise. It is commonly found in baked goods like muffins and pastries, as well as in some beverages.

Health notes

Potassium bicarbonate is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of potassium, an essential mineral. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated potassium bicarbonate and established an acceptable daily intake. Evidence does not suggest adverse health effects at typical dietary intakes.

Allergen info

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