Edible alkali refers to soda ash (sodium carbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3) which are different from industrial alkali.

Baking soda is the finished product after absorbing carbon dioxide from soda solution or crystal, and there is no essential difference between them. So edible alkali is also called baking soda (powder) in some places. Edible alkali is solid, round, white and easily soluble in water.

Edible alkali can be divided into baking soda and baking soda. Baking soda, also known as soda ash, is mainly composed of sodium carbonate (Na2CO3), which is very effective and corrosive. It is used for the primary processing of special foods and cannot be directly imported. The main component of baking soda is sodium bicarbonate (NaHCO3), which has a mild effect. It is a common acid foaming agent for food, and it is non-irritating when used in moderation.

The bubbles produced by baking soda are quickly used to make noodles swell and soften, which is strong in edible alkalinity and used to neutralize the acidic substances produced by fermentation.

It is just a kind of food expansion agent and meat tenderizer, which can make dry raw materials expand rapidly, soften fibers and remove the sour taste of dough. Proper use can bring excellent color, fragrance, taste and shape to food and stimulate people's appetite. Alkali is widely used in the processing of noodles, bread, steamed bread and other foods.
