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. |

| DL-Tartaric acid Usage And Synthesis |
| Chemical Properties |
Tartaric acid, HOOC(CHOH)2COOH, is a water- and alcohol-soluble colorless crystalline solid with an acid taste and a melting temperature of 170°C (338 OF). It is also known as dihydroxy succinic acid. Tartaric acid is used as a chemical intermediate and a sequestrant,as well as in tanning, effervescent beverages, baking powder, ceramics, photography, textile processing,mirror silvering,and metal coloring. |
| Chemical Properties |
Tartaric acid is odorless, but has a characteristic acid taste. Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms of tartrates are dextrorotatory in solution and thus are designated as L(+)-tartrates. For a detailed description on this chemical, refer to Burdock (1997). |
| Occurrence |
d-Tartaric acid occurs in many fruits or other parts of the plant, free or combined with potassium, calcium or magnesium. It is also reported found in raw, lean fish, white wine, red wine and port wine. |
| Preparation |
The tartrates used in commerce are obtained as a by-product of wine manufacture and have the L(+) configuration. Produced from argols or wine lees, which are formed in the manufacture of wine by extracting the potassium acid tartrate, transforming this into the calcium salt and then acidifying with dilute sulfuric acid; also by oxidation of d-glucose with nitric acid. The dl-tartaric acid is obtained by boiling the d-tartaric acid with an aqueous solution of NaOH or by oxidation of fumaric acid. The l- and the meso-tartaric acid are also known, but are less important. |
