Is soda vegan?

On food labels, soda typically refers to baking soda, which is the chemical compound sodium bicarbonate, or occasionally to carbonated water such as club soda. As a leavening agent, sodium bicarbonate is primarily produced through the Solvay process using sodium chloride, ammonia, and carbon dioxide, or by mining and refining trona, a naturally occurring mineral ore. It is commonly found in baked goods such as cakes, breads, and cookies, as well as in effervescent beverages and confections.

Soda is vegan because it originates strictly from mineral and synthetic sources without the use of animal products. No animal-derived inputs, processing aids, or byproducts are involved in the mining of trona ore, the chemical synthesis of sodium bicarbonate, or the carbonation of water. Because it contains only inorganic mineral salts or carbonated water, any ingredient listed simply as soda satisfies vegan criteria.
