Lactic Acid Cultures

Lactic acid cultures are live microorganisms, typically bacteria, that produce lactic acid as part of their metabolic process. They are naturally found in many foods and are also intentionally added to foods to help develop specific flavors and textures. These cultures are grown in a controlled environment for use in food production.

Manufacturers use lactic acid cultures to ferment dairy products like cheese, yogurt, and sour cream, giving them their characteristic tangy flavor and creamy texture. They are also used in some plant-based alternatives to dairy products and in certain fermented vegetables. The cultures act as a natural preservative and contribute to the overall flavor profile.

Lactic acid cultures are generally recognized as safe (GRAS) by the FDA for use in food. They are a natural part of many fermented foods and are considered beneficial by some for gut health, though scientific evidence is still developing. International bodies like JECFA and EFSA have evaluated lactic acid and its salts, and have established acceptable daily intakes. No significant health concerns are associated with the consumption of foods containing these cultures at typical levels.
