It appears as white or off-white crystalline powder/granules, with a mild, pure sour taste, slight hygroscopicity, and is freely soluble in hot water. As a multifunctional natural ingredient, it acts as a pH regulator, flavor enhancer, preservative, and humectant, widely used in food, cosmetics, pharmaceuticals, and feed industries.
