Potassium Lactate and the Vegetarian Diet
Potassium lactate is a potassium salt of lactic acid commonly used in the food industry as a preservative and humectant. It helps maintain moisture and extend the shelf life of food products. Lactic acid, the precursor of potassium lactate, can be produced via fermentation of carbohydrates or derived from animal sources, which is why its origin may concern vegetarians and vegans. It is important for those following specific dietary restrictions to verify the source of lactic acid used in potassium lactate.
