Baking powder is a chemical leavening agent (typically sodium acid pyrophosphate base with sodium bicarbonate) serving bakery operations, food manufacturing, and household cooking where CO? gas generation creates texture and rise in baked goods. Double-acting formulations release gas during mixing (moisture activation) and again during baking (heat activation) versus single-acting powders reacting only with moisture, with professional bakers preferring double-acting for more forgiving process timing and consistent results across production batches.
