What it is

Sodium bicarbonate is a white crystalline powder. It is a salt of carbonic acid, naturally occurring in mineral deposits and also produced industrially. It is commonly known as baking soda.

Why it's used

Sodium bicarbonate is a leavening agent, meaning it helps baked goods rise. When heated or combined with an acid, it releases carbon dioxide gas, causing doughs and batters to expand. It is found in a wide variety of baked goods, including cookies, cakes, and breads.

Health notes

Sodium bicarbonate is generally recognized as safe (GRAS) by the FDA for use in food. It is a common ingredient in antacids and can help neutralize stomach acid. JECFA has evaluated sodium bicarbonate and established an acceptable daily intake. At typical dietary levels, it is not associated with adverse health effects.

Allergen info

Sodium bicarbonate is not one of the nine major allergens and does not contain gluten.
