Baking soda is a weak base and an absorptive antacid. After oral administration, it can quickly neutralize gastric acid, which has many disadvantages such as rapid action, short duration and carbon dioxide production. As an antacid, it is not suitable to be used alone, and it is often used with calcium carbonate or magnesium oxide to form sibelide powder.

Extended data:

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.
