Baking soda, adding some acidic salts such as tartar powder (tartaric acid) and corn starch as fillers.

Baking soda, chemical name sodium bicarbonate, chemical formula NaHCO? . Properties: white powder or fine crystal, odorless, salty, soluble in water. It decomposes rapidly in weak acid, and its aqueous solution begins to decompose carbon dioxide and sodium carbonate at 20℃, and all of them are decomposed at boiling point.

This characteristic is often used as a starter 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.

Tata powder: the chemical name is potassium hydrogen tartrate, which is one of the essential raw materials for making Qifeng cake. Used in baking powder to decompose baking soda and neutralize alkaline taste.

Corn starch, no explanation.

Moderate consumption is harmless to the human body. Baking soda can also promote gastrointestinal function.

But excessive consumption is not enough. Just as people can't eat too much salt, it will lead to dehydration and cell necrosis.
