Edible baking soda is mainly used as the generator of carbon dioxide in food, soft drinks and cold drinks, and also used in feed additives, medicine, chemistry, tanning, fire-fighting preparations, biological breeding, detergents, environmental desulfurization, sterilization and detoxification, bathing and health care industries.
Baking soda is made from soda solution or crystal after absorbing carbon dioxide. Therefore, baking soda is also called edible alkali (powder) in some places. Baking soda is solid, round, white in color and easily soluble in water.
In mass production of steamed bread, fried dough sticks and other foods, the melted water of baking soda powder is often mixed into noodles, which is decomposed into sodium carbonate, carbon dioxide and water after heating, and carbon dioxide and water vapor overflow, which can make the food more fluffy and sodium carbonate remains in the food. Too much baking soda can be tasted in steamed bread.
