What it is

Vinegar is a liquid made from the fermentation of ethanol by acetic acid bacteria. Citric acid is a weak organic acid found naturally in citrus fruits like lemons and limes. Both are commonly used as food ingredients.

Why it's used

Vinegar and citric acid are primarily used to add a sour or tart flavor to foods. They also act as preservatives by lowering the pH, which can inhibit microbial growth. They are found in a wide variety of products, including salad dressings, sauces, pickles, canned vegetables, and snack foods like chips and pretzels.

Health notes

Vinegar and citric acid are generally recognized as safe (GRAS) by the FDA for use in food. Citric acid occurs naturally in the body and is an important part of energy production. While generally safe, high concentrations of citric acid can erode tooth enamel. International bodies like JECFA have evaluated these ingredients. Evidence does not suggest adverse health effects from consuming these ingredients at typical levels found in food.

Allergen info

Neither vinegar nor citric acid are derived from any of the FDA's major allergens. They do not contain gluten.
