Single-acting baking powders instantly produce most of their gas when mixed with a liquid. There are two categories of baking powders: single acting and double acting. The company he created became known as Rumford. He placed the two ingredients together in one container, adding cornstarch to soak up moisture, which prevented the ingredients from reacting prematurely. The monocalcium phosphate acted as an acid that combined with baking soda to create a reaction producing C02.īy the 1880s, Horsford’s company switched to mining the monocalcium phosphate to lower costs. Horsford originally extracted monocalcium phosphate by boiling animal bones. In 1856, chemist Eben Norton Horsford patented the first modern baking powder. Because carbon dioxide is released at a faster rate through the acid-base reaction than through fermentation, breads made by chemical leavening are called quick breads. But as soon as the baking powder is stirred into a wet dough or batter, the two ingredients begin to react, releasing bubbles of CO2 and causing chemical leavening.īaking powder was discovered by English food manufacturer Alfred Bird in 1843.It is used instead of yeast for end-products where fermentation flavors would be undesirable or where the batter lacks the elastic structure to hold gas bubbles for more than a few minutes, or to speed the production. Monocalcium phosphate doesn’t react with the sodium bicarbonate while it’s dry. One of these acids is called monocalcium phosphate. But baking powder also contains two acids. It is used instead of yeast for end-products where fermentation flavors would be undesirable or where the batter lacks the elastic structure to hold gas bubbles for more than a few minutes, or to speed the production.Īll baking powders consist of sodium bicarbonate (just like baking soda). Baking powder works by releasing carbon dioxide gas into a batter or dough through an acid-base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. Baking powder is made up of Baking soda (sodium bicarbonate, NaHCO3), cream of tartar (potassium bitartrate, C4H5KO6), and cornstarch. Baking powder is actually a dry chemical leavening agent, which is a mixture of a carbonate or bicarbonate and a weak acid and is used for increasing the volume and lightening the texture of baked goods.
