What it is

This refers to the concentration of acetic acid, the main component that gives vinegar its sour taste and preservative qualities. It is produced through a two-step fermentation process, first converting sugars to alcohol (ethanol) and then converting the alcohol to acetic acid by acetic acid bacteria.

Why it's used

Manufacturers use vinegar primarily as an acidity regulator and preservative in foods. Its sharp flavor also makes it a key ingredient in salad dressings, marinades, sauces, and pickles, adding tang and balancing sweetness.

Health notes

Vinegar is generally recognized as safe (GRAS) by the FDA for use in food. While some studies suggest potential benefits for blood sugar control when consumed in moderation, research is ongoing and not conclusive. International bodies like JECFA have evaluated vinegar, but no specific numeric limits were set.

Allergen info

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