Sodium Bicarbonate & Ammonium Bicarbonate

Sodium bicarbonate (baking soda) and ammonium bicarbonate are chemical compounds used as leavening agents. Sodium bicarbonate is a white crystalline powder that occurs naturally and is also synthesized. Ammonium bicarbonate is also a white crystalline powder, produced by combining ammonia and carbon dioxide.

These ingredients react with moisture and heat to produce carbon dioxide gas, causing doughs and batters to rise and become lighter. They are commonly found in baked goods like cookies, crackers, and cakes, as well as in some snack foods.

Both sodium bicarbonate and ammonium bicarbonate are generally recognized as safe (GRAS) by the FDA for use in food. When consumed in the amounts typically found in food, they are not associated with adverse health effects. International bodies like JECFA have evaluated these substances. Evidence does not suggest significant health concerns at typical dietary levels.
