What it is

Diluted to 5% acidity is a common strength for vinegar, which is a liquid made by a two-step fermentation process. First, sugars from sources like fruit or grains are fermented into alcohol. Then, a second fermentation turns the alcohol into acetic acid, which gives vinegar its sour taste and pungent smell.

Why it's used

Manufacturers use diluted vinegar as an acidity regulator and flavor enhancer. Its sharp taste is key in salad dressings, marinades, and sauces. It also acts as a preservative in pickles and other pickled foods, helping to extend shelf life.

Health notes

Vinegar, including diluted to 5% acidity, is generally recognized as safe (GRAS) by the FDA for use in food. Some research suggests acetic acid may have a modest effect on blood sugar levels after meals, but more studies are needed. International bodies like JECFA have evaluated vinegar and its components. High concentrations of undiluted acetic acid can be corrosive, but the 5% dilution in food is considered safe for consumption.

Allergen info

Vinegar is not derived from any of the FDA's 9 major allergens. It does not contain gluten.
