Baking powder is a commonly used food additive, also known as baking powder, baking powder or baking agent. It is mainly composed of sodium bicarbonate (sodium bicarbonate), acids (such as citric acid or tartaric acid) and starch.

Baking powder, as an important auxiliary in baking, is mainly used to produce leavening during the baking process to make dough or cakes and other pastries swell and fluff. It works on the principle that when baking powder comes into contact with liquid or hot ingredients, the alkaline and acidic components react to produce carbon dioxide gas, which causes the dough or cake to expand in volume.

Using baking powder improves the texture and flavor of baked goods, making them fluffier and fluffier. It is suitable for making all kinds of pastry, cakes, cookies, buns and other baked products. In short, baking powder is a common leavening agent used in baking to make pastries fluffy and delicious. Proper use and storage of baking powder helps to improve the quality and taste of baked goods.
