Tartaric acid — Formally known as dihydroxybutanedioic acid
Tartaric acid is a naturally occurring organic acid that’s found in a number of fruits and plants including bananas, grapes, citrus, and tamarinds. Its basic chemical formula is C4H6O6, and its structural formula is HO2CCH(OH)CH(OH)CO2H.
The preferred IUPAC name for tartaric acid is 2,3-dihydroxybutanedioic acid, and its CAS Number is 526-83-0. Other names for tartaric acid include racemic acid, threaric acid, paratartaric acid, and uvic acid.
The salt of tartaric acid — potassium bitartrate or cream of tartar — is a natural byproduct that’s formed during the winemaking process. When blended with sodium bicarbonate, it is used as a leavening agent — in the form of baking powder — in food preparation. Tartaric acid has the E number E334 and is used as an antioxidant in the food industry. Due to its palatable sour taste, it is also used as a flavoring agent.
The first known production of tartaric acid was from the residues of winemaking around 800 A.D. In 1769, a more modern production process based on fermentation was developed by Carl Wilhelm Scheele.

Industries Where Tartaric Acid Is Widely Used
The food and beverage industry prizes tartaric acid as a well-known acidulant that has the ability to give food products a tart, sharp flavor. In addition, it acts as a preservative — plus, it can promote the setting of gelatin. For these reasons, it is often a food grade additive in jellies with fruit flavors, many types of carbonated beverages, and tablets.
For bakeries and confectionery makers, tartaric acid is also a useful ingredient. For example, cream of tartar, which contains tartaric acid, is often used for preparing cake frostings, as well as in the production of several types of candies. When it is necessary to have a baked product rise without the use of yeast cultures, the tartaric acid found in baking powder is ideal because it gives off carbon dioxide gas when it reacts with the sodium bicarbonate found in baking soda. The result is a product that rises without any yeast flavor.
In the wine making industry, tartaric acid — along with possibly malic and citric acids — is largely to thank for bringing out the tartness of the grapes in a good wine. In addition, tartaric acid’s uses go far beyond flavoring. In the fermentation process, the ingredient acts as a preservative by helping lower the pH so that certain bacteria that could otherwise cause a wine to spoil cannot grow.
In the medical and pharmaceutical sectors, tartaric acid has further applications. It is a popular additive used to improve the flavors of various oral medications that are produced in effervescent tablet form. The acid’s derivative — tartar emetic — is employed as an expectorant in many cough syrups. In addition, the medical industry relies on tartaric acid when preparing solutions used to determine glucose — or blood sugar — levels. Plus, it is used in the production of Rochelle Salt — a known laxative.
Tartaric acid also serves as a key ingredient in several industrial applications, including the silvering of mirrors, the dying of textiles, the tanning of leather goods, and the production of lacquers, as well as the fabrication of blue ink used in blueprints. It is also prized among metals manufacturers for its ability to clean surfaces made of copper, iron, aluminum, and many related alloys.
CHEMICAL PROPERTY INFORMATION FOR TARTARIC ACID
Of all acidulants in solid form, tartaric acid is the one with the highest solubility in water. It is both a diprotic and dicarboxylic organic acid. It is typically white or colorless and crystalline in form. Tartaric acid is also one of the of the most widely present plant acids, and its presence as a byproduct of wine making was known all the way back to the ancient days of Greece and Rome.
