Anhydrous citric acid is a food-grade acidulant, appearing as white crystalline powder with low moisture content and good anti-caking property. It delivers mild sour taste and features functions of acid regulation, color protection and metal ion chelation, widely applied in powdered drinks, bakery products, daily chemicals and pharmaceuticals. It is more suitable for powder processing with stable performance, and resists caking and deterioration during storage and transportation.
