Differences in Application Between Citric Acid Monohydrate and Anhydrous Citric Acid
Citric Acid MonohydrateHydrous crystal, low melting point, easy to absorb moisture and agglomerate.Mainly used for beverages, liquid food, seasonings, daily chemicals, water treatment and metal cleaning. Not suitable for high-temperature or powder products.
Anhydrous Citric AcidMoisture-free, high temperature resistant, good fluidity, low hygroscopicity.Mainly used for powdered food, effervescent tablets, baking, pharmaceutical solid preparations and solid health products, applicable to high-temperature processing.
Brief rule: Monohydrate for liquid & aqueous products; Anhydrous for powder, effervescent and high-temperature solid formulations.
