Baking powder is a kind of compound leavening agent, which is made of baking soda powder with acidic materials and corn flour as filler. It is also called foaming powder and baking powder. Baking powder is a rapid starter, which is mainly used for the rapid fermentation of grain products. In the production of cakes, cakes, steamed buns, steamed bread, shortbread, bread and other foods, the dosage is large.

Although baking powder contains soda powder, it is added with acid powder (such as tata powder) after precise detection to balance its pH value. Therefore, basically, although baking powder is alkaline, baking powder on the market is neutral. Therefore, baking powder and baking powder cannot be replaced at will.

As a filler in baking powder, corn flour is mainly used to separate acidic powder and alkaline powder in baking powder to avoid their premature reaction. Baking powder should also be preserved as far as possible to avoid premature failure due to moisture.
