What it is

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

Why it's used

Manufacturers add sodium bicarbonate primarily as a leavening agent in baked goods, where it reacts with acidic ingredients to produce carbon dioxide gas, causing doughs and batters to rise. It is also used as an acidity regulator and a cleaning agent in some food products.

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 is used to neutralize stomach acid. JECFA has evaluated sodium bicarbonate and established an acceptable daily intake. Evidence does not suggest adverse health effects from typical dietary intake.
