Superiority
Tartaric acid is a white crystalline organic acid that occurs naturally in many plants, most notably in grapes. Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of winemaking. It is commonly mixed with sodium bicarbonate and is sold as baking powder used as a leavening agent in food preparation. The acid itself is added to foods as an antioxidant and to impart its distinctive sour taste.

Application of L tartaric acid
1.L(+)Tartaric acid is mainly used as acidulant in beverage,and other foods, such as soft drinks, wine, candy, bread and some colloidal sweetmeats.
2.Used as catalyst in the resin finishing of polyester fabric or pH value regulator in oryzanol production
3. Used as complexing agent, screening agent or chelating agent in chemical analysis and pharmaceutical inspection, or as resist agent in dyeing.
4.Also complex with metal ion and can be used as cleaning agent or polishing agent of metal surface.
