Baking Powder: E450 & E500

Baking powder is a chemical leavening agent used in baking. It typically contains a carbonate or bicarbonate salt (like sodium bicarbonate, E500) and an acid salt (like sodium acid pyrophosphate, E450). When mixed with liquid and heated, these ingredients react to produce carbon dioxide gas, which makes baked goods rise.

Manufacturers add baking powder to baked goods to make them light and fluffy. It is a key ingredient in cakes, cookies, muffins, and quick breads. It provides leavening, which is the process of creating gas bubbles that expand during baking.

In the US, the components of baking powder are generally recognized as safe (GRAS) by the FDA when used as intended. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated these substances. Typical intake from food is not associated with adverse health effects. Some individuals may be sensitive to phosphates, but this is rare at levels found in food.
