Appearance

Anhydrous citric acid is a colorless, semi transparent crystal or white particle, or a white crystalline powder. Relative density 1.542, melting point 153 ℃ (water loss), refractive index 1.493~1.509. It often contains one molecule of crystalline water. Odorless, extremely sour in taste, soluble in water, alcohol, and ether. Its calcium salts are more soluble in cold water than in hot water, and this property is often used to identify and separate citric acid. Control the appropriate temperature during crystallization to obtain anhydrous citric acid. The aqueous solution is acidic. Slightly weathered in dry air and deliquescent in humid air. Decomposition above 175 ℃ releases water and carbon dioxide.

It is mainly used as an acidulating, flavoring and preservative in Foods and beverages. It is also used as antioxidant, plasticizer and Detergent builder.

In 25kg,500kg,1000kg bag with or without pallet.

Citric acid monohydrate loses its crystalline water in dry air or when heated to about 40 degrees Celsius, and undergoes slight deliquescence in humid air. A dilute aqueous solution of citric acid can ferment while still. So solid monohydrate or anhydrous substances should be stored in airtight containers and stored in a cool and dry place.
