What it is

This ingredient is a liquid solution of acetic acid, a weak organic acid. It is commonly produced through the fermentation of ethanol, often derived from grains like rice, corn, or barley. The fermentation process converts ethanol into acetic acid, which is then diluted with water to achieve a specific acidity level.

Why it's used

Diluted acetic acid is primarily used as an acidity regulator and preservative in foods. Its tart, sour flavor also makes it a key component in dressings, marinades, and sauces, especially in Asian cuisine like sushi. It helps to balance flavors, inhibit microbial growth, and extend shelf life.

Health notes

Acetic acid is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a natural component of vinegar and is produced by the body during metabolism. International bodies like JECFA have evaluated acetic acid and its salts, establishing acceptable daily intakes. At typical food consumption levels, it is not associated with adverse health effects.

Allergen info

Not a major allergen. However, if the acetic acid is derived from wheat or barley, it may contain gluten. Labels should be checked for specific sourcing.
