Baking Powders: Diphosphates And Sodium Carbonates

Baking powder is a chemical leavening agent used in baking. It typically contains an acid salt, such as a diphosphate, and a base, such as sodium carbonate. When mixed with liquid and heated, these ingredients react to produce carbon dioxide gas, which causes doughs and batters to rise.

Manufacturers add baking powder to baked goods to help them rise and achieve a light, fluffy texture. It is commonly found in cakes, cookies, biscuits, and muffins. The diphosphates provide a fast or slow leavening action depending on the specific type.

Diphosphates and sodium carbonate are generally recognized as safe (GRAS) by the FDA when used for leavening. They are common ingredients in many foods and are not associated with adverse health effects at typical dietary intakes. International bodies like JECFA have evaluated phosphates and found them safe for consumption.
