What it is

Nondairy lactic acid is an acid produced by the fermentation of carbohydrates, such as sugars from corn or beets. It is a natural organic acid that gives sour milk its tart flavor. It is used in foods when a dairy-free source of lactic acid is needed.

Why it's used

Nondairy lactic acid is used as an acidity regulator, preservative, and flavor enhancer in a variety of foods. It helps control pH, extend shelf life, and add a tangy or sour taste. It is commonly found in baked goods, dairy alternatives, and confectionery.

Health notes

Nondairy lactic acid is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. Regulatory bodies like JECFA and EFSA have evaluated lactic acid and its salts. At typical consumption levels, it is considered safe and is a normal component of human metabolism.

Allergen info

Nondairy lactic acid is not derived from any of the nine FDA major allergens. It does not contain gluten.
