Enzytec™ Citric Acid is an enzymatic test for the determination of citric acid in foodstuffs and other materials.
For in vitro use only.
General Information:
Citric acid is a very important metabolite in animals, plants and micro-organisms. It is the best known acid of the fruit acids and is contained in a high amount e. g. in citrus fruits (approx. 10 g citric acid/l orange juice). Citric acid is manufactured biotechnologically on a large scale as an additive for food (E330). Citric acid is used as preservative (acidifier) for food or cosmetics, as a chelating agent for metals (e.g. for iron in wine), as an emulsifier (e. g. in the production of processed cheese), and as flavoring agent in the production of soft drinks and candies. It is also a component of many pharmaceuticals and washing powders.
