Tartaric acid crystals are colorless, transparent and odorless with acidic taste. Soluble in water, alcohol, and ether. Tartaric Acid is derived by extraction from argol -- a sediment in wine vats. Food grade Tartaric Acid is added to many foods to give a sour taste and as an antioxidant.Important derivatives of tartaric acid includes its salts, cream of tartar (potassium hydrogen tartrate), Rochelle salt (potassium sodium tartrate, a mild laxative) and tartar emetic (antimony potassium tartrate).
Tartaric Acid is widely used as acidulant in beverage,and other foods, such as soft drinks, wine, candy, bread and some colloidal sweetmeats. With its optical activity, Tartaric Acid food grade is used as chemical resolving agent to resolve DL-amino-butanol, an intermediate for antitubercular drug. And it is used as chiral pool to synthesize tartarate derivatives. With its acidity, Tartaric Acid is used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production.This product is also used as complexing agent, screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing. With its reduction,Tartaric Acid food grade is used as reductive agent in manufacturing mirror chemically or imaging agent in photography. Tartaric Acid can also complex with metal ion and can be used as cleaning agent or polishing agent of metal surface.
