Sugar Baking Powder

Baking powder is a chemical leavening agent used in baking. It is a mixture of a base (usually sodium bicarbonate, also known as baking soda), an acid salt (such as cream of tartar or sodium aluminum sulfate), and a filler (like cornstarch or flour) to absorb moisture and prevent clumping. When mixed with liquid and heated, the acid and base react to produce carbon dioxide gas, which causes doughs and batters to rise.

Manufacturers add baking powder to baked goods to make them light and fluffy. It's a key ingredient in cakes, cookies, muffins, and quick breads. The carbon dioxide gas it produces creates air pockets, resulting in a desirable texture.

Baking powder is generally recognized as safe (GRAS) by the FDA when used as a leavening agent. The ingredients in baking powder are common food substances. The FDA has not set specific upper intake limits for baking powder as a whole, but its components are generally considered safe in typical dietary amounts. JECFA and EFSA have evaluated some individual components, like sodium bicarbonate and certain acid salts, and found them safe for use.
