What it is

This is a solution of acetic acid, the main component of vinegar, diluted with water to a specific concentration of 4.3% acidity. Acetic acid is produced industrially through the fermentation of ethanol by acetic acid bacteria or synthetically.

Why it's used

Manufacturers use diluted acetic acid primarily as an acidity regulator and preservative. It adds a sour or tart flavor to foods. It is commonly found in salad dressings, sauces, pickles, and marinades.

Health notes

In the US, acetic acid is Generally Recognized As Safe (GRAS) by the FDA when used as a food additive. It is a common component of vinegar, which has been consumed for centuries. International bodies like JECFA have evaluated acetic acid and its salts, establishing acceptable daily intake levels. At typical consumption levels in food, it is not associated with adverse health effects.
