Products Description of Citric acid CAS#77-92-9

Anhydrous citric acid is a natural component and intermediate product of physiological metabolism in animals and plants. It is also one of the most widely used organic acids in the fields of food, medicine, and chemical industry. It is a colorless, transparent or translucent crystal, or granular or microparticle powder. It is odorless and has a strong sour taste, but it is pleasant and has a slightly astringent aftertaste. It gradually weathers in warm air and is slightly deliquescent in humid air.
