Sodium Acid Bicarbonate

Sodium acid bicarbonate, also known as sodium bicarbonate or baking soda, is a white crystalline powder. It is a salt of carbonic acid, naturally occurring as the mineral nahcolite. It is manufactured industrially through the Solvay process or by mining and purifying nahcolite.

It is a common leavening agent in baked goods, producing carbon dioxide gas when heated or combined with an acid, which causes doughs and batters to rise. It is also used as an acidity regulator and a flavor enhancer in various food products.

Sodium acid bicarbonate is generally recognized as safe (GRAS) by the FDA for use in food. It is a common ingredient, and typical dietary intake is not associated with adverse health effects. International bodies like JECFA and EFSA have evaluated sodium bicarbonate. While generally considered safe, excessive intake can lead to electrolyte imbalances and other health issues.
