Tartaric acid is a white crystalline diprotic aldaric acid. It occurs naturally in many plants, particularly grapes, bananas, and tamarinds, is commonly combined with baking soda to function as a leavening agent in recipes, and is one of the main acids found in wine. It is added to other foods to give a sour taste, and is used as an antioxidant. Salts of tartaric acid are known as tartrates. It is a dihydroxyl derivative of succinic acid.

MAIN FUNCTION AND PURPOSE |
This product is widely used in many fields such as foodstuff, medicine, chemical industry and light industry etc., and is mainly used to make tartrates (tartaric acid salts), like antimony potassium tartrate, potassium sodium tartrate. It can be served as beer vesicant, foodstuff sourness agent and flavoring etc. Its sourness is 1.3 times of that of citric acid, and is especially suitable to be a sourness agent of grape juice. It is also very important for the tannage, photograph, glass, enamel and telecommunication equipment industries. |
