Acetic Acid and the Shellfish Free Diet

Acetic acid is a colorless liquid organic compound most commonly known for being the primary component of vinegar, aside from water. It is a result of the fermentation of ethanol by acetic acid bacteria. In the context of food products, acetic acid can be produced synthetically as well, often using a base of corn glucose or corn mash, which may be relevant for individuals with corn allergies. Acetic acid is used in culinary applications as a preservative and flavoring agent.
