Edible baking soda: Unlike soda (sodium carbonate) and baking soda (sodium bicarbonate), baking soda is made from soda 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.
Simple water: also known as alkaline water, or edible simple water, is a compound food additive, a material in food technology, and a common traditional auxiliary material for Cantonese cakes.
