What it is

Potassium lactate is the potassium salt of lactic acid. It is produced by the fermentation of carbohydrates, such as those found in corn or sugar beets, by lactic acid bacteria. It is a white crystalline powder that is highly soluble in water.

Why it's used

Potassium lactate is used as a preservative and a flavor enhancer in processed meats, poultry, and fish. It helps to extend shelf life by inhibiting the growth of bacteria and other microorganisms. It also contributes a slightly salty taste and can help to retain moisture in meat products.

Health notes

Potassium lactate is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as a food additive. It is also approved for use in the European Union. International bodies like JECFA (Joint FAO/WHO Expert Committee on Food Additives) and EFSA (European Food Safety Authority) have evaluated potassium lactate and found it to be safe. At typical consumption levels found in food, it is not associated with adverse health effects.

Allergen info

Potassium lactate is not derived from any of the nine FDA major allergens and does not contain gluten.
