Citric Acid Anhydrous
General information
Citric acid is a natural occurring fruit acid, produced commercially by microbial fermentation of a carbohydrate substrate. Citric acid is the most widely used organic acid and pH-control agent in foods, beverages, pharmaceuticals and technical applications.
Citric acid anhydrous occurs as colourless 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.
Specification
Jungbunzlauer citric acid anhydrous is supplied in accordance with the current requirements of the European Pharmacopoeia (Ph. Eur), the United States Pharmacopeia (USP), the Food Chemicals Codex (FCC), and the Commission Regulation (EU) No. 231/2012.

Legal aspects
In Europe, citric acid anhydrous is listed as generally permitted food additive (E330) and may be added to all foodstuffs, following the “quantum satis“ principle, as long as no special regulation restricts the use.
The US Food and Drug Administration (FDA) has affirmed citric acid as GRAS (generally recognised as safe) and permitted the use in food according to current GMP (CFR § 184.1033), without setting an upper limit.
Jungbunzlauer citric acid has been registered according to REACH Regulation at the European Chemicals Agency (ECHA) in 2010. The REACH registration number of Jungbunzlauer citric acid is 01-2119457026-42-0000.
