Citric acid is a natural fruit acid, produced commecially by microbial fermentation of a carbohydrate substrate.
Citric acid is the most widely used organic acid and pH-control agent in foods, beverage, pharmaceutical and technical application.
Citric acid anhydrous occurs as colorless crystals or as white, crystalline powder with a strongly acidic taste. It is very soluble in water, freely soluble in ethanol (96%) and sparingly soluble in ether.
Citric acid anhydrous is non-toxic and has a low reactivity. It is chemically stable if stored at ambient temperatures. Citric acid anhydrous is fully biodegradable and can be disposed of with regular waste or sewage.
