What it is

Lactic acid is an organic acid naturally found in the body and in certain foods. It is produced commercially through the fermentation of carbohydrates, such as corn starch or beet sugar, by lactic acid bacteria.

Why it's used

Lactic acid is used as an acidity regulator to control pH in foods, contributing a mild, sour taste. It also acts as a preservative by inhibiting microbial growth. It is commonly found in pickles, olives, cheeses, and marinades.

Health notes

Lactic acid is generally recognized as safe (GRAS) by the FDA. It is a natural component of human metabolism. International bodies like JECFA and EFSA have evaluated lactic acid and its salts, and have established acceptable daily intakes. Evidence does not suggest adverse health effects from typical dietary consumption.

Allergen info

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