sodium bicarbonate

Sodium bicarbonate, chemical formula NaHCO? Commonly known as baking soda. White fine crystal, more insoluble in water than sodium carbonate. It is also an industrial chemical. Solids above 50℃ begin to decompose gradually to produce sodium carbonate, carbon dioxide and water, and completely decompose at 270℃. Sodium bicarbonate is an acid salt formed by neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water. This characteristic can make it a leavening agent in food production. Sodium carbonate will remain after the action of sodium bicarbonate, and excessive use will make the finished product have an alkaline taste.

Edible sodium bicarbonate

Unlike soda ash (sodium carbonate) and baking soda (sodium bicarbonate), baking soda is made from soda ash solution or crystal after absorbing carbon dioxide. So baking soda is also called edible alkali (powder) in some places Baking soda is solid, round, white and easily soluble in water.

In the mass production of steamed bread, fried dough sticks and other foods, noodles are often mixed with melted water of baking soda powder, which is decomposed into sodium carbonate, carbon dioxide and water after heating. Carbon dioxide and water vapor overflow, which can make the food more fluffy, and sodium carbonate remains in the food. Too much baking soda in steamed bread will taste.
