Lactic Acid Culture

A lactic acid culture is a starter culture containing live bacteria that produce lactic acid. These bacteria are naturally found in milk and other foods, and are often added to foods to help with fermentation and preservation. They are commonly used in dairy products and fermented vegetables.

Lactic acid cultures are primarily used to produce lactic acid, which acts as a preservative and flavor enhancer. They are also used to create the characteristic tangy flavor and texture in fermented foods like yogurt, cheese, pickles, and sauerkraut. Manufacturers add them to extend shelf life and improve taste.

Lactic acid cultures are generally recognized as safe (GRAS) by the FDA for use in food. The bacteria in these cultures are often beneficial probiotics, which may support gut health. International bodies like JECFA and EFSA have evaluated lactic acid and its salts, generally considering them safe for consumption. Evidence does not suggest adverse health effects from consuming foods containing lactic acid cultures at typical intake levels.
