General description

Acetic acid is an organic acid mainly used as a preservative, acidulating agent and flavoring agent. It is one of the main volatile constituents of vinegar and pyroligneous acid. In combination with leavening agents, it produces carbon dioxide from sodium bicarbonate. Acetic acid is used as flavoring agent in ice-creams, nonalcoholic beverages and baked goods.
