Baking soda and edible alkali are not the same thing. The main differences are as follows:

1, composition difference

Edible alkali is a common condiment, which is mainly composed of sodium carbonate and sodium bicarbonate. The baking soda in life is actually the common name of sodium bicarbonate, so its main component is sodium bicarbonate.

2, alkaline difference

Edible alkali is generally alkaline and easily soluble in water; However, baking soda is generally weakly alkaline and difficult to dissolve in water. Generally, it can only be melted and decomposed in warm water at 50 degrees.

3. Difference in efficacy

Edible alkali is generally used to decompose protein in food and help food to be preserved; Baking soda is mainly used as a starter for food, such as steamed bread and bread.

4. Stability difference

Generally, the stability of edible alkali is relatively strong, and it is generally not easily decomposed; The stability of baking soda is poor, and it is easy to decompose into sodium carbonate, water, carbon dioxide and other substances after heating.
