What it is

Acetic acid is a chemical compound that gives vinegar its sour taste and pungent smell. It is found naturally in small amounts in fruits and vegetables, but is typically produced industrially through the fermentation of ethanol or the oxidation of hydrocarbons.

Why it's used

Acetic acid is widely used as an acidity regulator, preservative, and flavoring agent in food. It helps control pH, prevent spoilage, and add a tangy or sour taste to products like salad dressings, pickles, sauces, and baked goods.

Health notes

Acetic acid is generally recognized as safe (GRAS) by the FDA for use in food. It is a normal component of metabolism and is not associated with adverse health effects at typical dietary intake levels. International bodies like JECFA have evaluated acetic acid and its salts, and EFSA has also assessed its safety.

Allergen info

Acetic acid is not derived from any of the 9 FDA major allergens. It does not contain gluten.
