Baking powder is a kind of white powder, which contains acid substances such as baking soda powder and corn flour as filler. When baking powder reacts with water, acidic and alkaline powders are dissolved in water at the same time, and some of them will start to release carbon dioxide (co? ), at the same time, in the process of baking and heating, more gas will be released, which will make the product expand and soften.

Fast-reaction baking powder starts to work only when it is dissolved in water, while slow-reaction baking powder starts to work during baking and heating. Among them, "double reaction baking powder" has the reaction characteristics of fast and slow baking powder.

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