What it is
Baking soda, also known as sodium bicarbonate, is a white crystalline powder. It is a salt composed of sodium and bicarbonate ions. It occurs naturally as the mineral nahcolite, but is most often produced synthetically.
Why it's used
Baking soda is primarily used as a leavening agent in baked goods, producing carbon dioxide gas when combined with an acid and moisture. This causes doughs and batters to rise. It is also used as a pH buffer and can be found in a variety of processed foods.
Health notes
Baking soda 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. When consumed in very large amounts, it can cause side effects like gas, bloating, and electrolyte imbalances. JECFA has evaluated sodium bicarbonate and established an Acceptable Daily Intake (ADI).
