Acidifier

Acidifiers are substances that increase the acidity of foods. They are often organic acids, naturally found in fruits and vegetables, or produced through fermentation or chemical synthesis. Common examples include citric acid, malic acid, and lactic acid.

Acidifiers are used to add a tart or sour taste to foods and beverages, and to help preserve them by lowering pH. They can also enhance the flavor of other ingredients, act as antioxidants, and help set pectin in jams and jellies. They are found in a wide variety of products, including candies, soft drinks, processed fruits and vegetables, and dairy products.

Acidifiers are generally recognized as safe (GRAS) by the FDA when used for their intended purpose. International bodies like JECFA and EFSA have also evaluated many common acidifiers. At typical consumption levels, they are not associated with adverse health effects. Some studies have explored the role of dietary acidity in relation to dental enamel erosion, but this is primarily a concern with frequent exposure to highly acidic foods and beverages.
