What it is

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

Why it's used

Manufacturers add lactic acid to foods to lower pH, which helps preserve them and enhance their flavor. It provides a mild, tangy taste and is commonly found in pickles, olives, candies, and dairy products.

Health notes

Lactic acid is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a natural part of human metabolism. International bodies like JECFA and EFSA have evaluated lactic acid and its salts, finding them safe for consumption. Evidence does not suggest adverse health effects from typical dietary intake.

Allergen info

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