Tartaric acid,2, 3-dihydroxysuccinic acid. Molecular formula :HOOCCHOHCHOHCOOH is dihydroxysuccinic acid. There are two asymmetric carbon atoms, with three stereoisomers, namely: right-handed (D-type, L-type), left-handed (L-type, D-type), meso type. Generally, racemic tartaric acid is also called gluconic acid. Dextrotartaric acid is widely distributed in higher plants in the form of free or K salt, Ca salt, Mg salt, especially in fruits and leaves. In the manufacture of wine, a large amount of tartar (hydrogen potassium salt) is deposited. It is also commonly found in molds and lichens. The recently isolated tartaric acid-fermenting bacteria (a variant of Gluconoba-ctersuboxydans) work in the body via glucose oxygen
As an antioxidant added to food, it can give food a sour taste. The largest use of tartaric acid is as a beverage additive. It is also the raw material of pharmaceutical industry. In the mirror industry, tartaric acid is an important additive and reducing agent, which can control the formation rate of silver mirror and obtain a very uniform coating. Used as biochemical reagent, masking agent and beer foaming agent, also used in tanning industry. L(+) -tartaric acid is widely used as a souring agent in beverages and other foods, including wine, soft drinks, sweets, breads, and certain gelatinous sweets. It is mainly used as sour agent, separation agent and pharmaceutical raw material.
