Baking Soda Baking Powder

Baking soda is sodium bicarbonate, a white crystalline powder. It's a naturally occurring mineral salt. Baking powder is a mixture that typically contains baking soda, an acid salt (like cream of tartar), and a filler (like cornstarch).

Baking soda and baking powder are leavening agents. When mixed with liquid and heat (or acid), they produce carbon dioxide gas, which makes baked goods rise and become fluffy. They are most commonly found in baked goods like cookies, cakes, and breads.

Baking soda (sodium bicarbonate) is Generally Recognized As Safe (GRAS) by the FDA. It is used in small amounts in food and is also an active ingredient in some over-the-counter medications for indigestion. JECFA has evaluated sodium bicarbonate and set an acceptable daily intake. Baking powder, containing sodium bicarbonate and other ingredients, is also considered safe for its intended use in food. There are no major health controversies associated with the typical consumption of these ingredients.
