Citric acid anhydrous is widely used in the food, beverage, and pharmaceutical industries to impart a clean, refreshing tartness. Its prime use is as an acidulant, but it is also used as a sequestrant of metal ions to give protection from the development of off-flavors and off-odors in certain foodstuffs.
Sodium Citrate Dihydrate is derived from citric acid and is available in either free-flowing colorless granular or powder forms. It is odorless and freely soluble in water, but insoluble in alcohol. Sodium Citrate Dihydrate is the most broadly used emulsifying salt in sliced processed cheese products. It is commonly used as a buffering agent in combination with citric acid to provide precise pH control required in many food and beverage applications. In meat products it is used as an anticoagulant of fresh livestock blood and as a curing accelerator. The detergent-building and rapid biodegradability characteristics of sodium citrate enable its use as an environmentally acceptable phosphate substitute in a large variety of household cleaning products.
