What is Tartaric Acid?

Tartaric acid is an organic acid that is a by-product of winemaking. It is characterized by its  sharp tart taste. In cakes and sweet baked goods production, tartaric acid is used as a fast-acting leavening acid in some baking powders.

As a food acid regulator, it can enhance the profile of fruit flavors and colors and stabilize batter systems. Its salt form, potassium acid tartrate, is commonly known as cream of tartar. Alternative forms of tartaric acid include:

  • Potassium bitartrate
  • Sodium potassium tartrate
  • Sodium tartrate


Tartaric acid is a natural acid which is widely distributed in nature in the form of 2 stereoisomers. It was first isolated by the alchemist Jabir Ibn Hayyan in Iraq in the 7th century. Resolving tartaric acid stereoisomers was done much later by Louis Pasteur in the 1840s.

Similar to other organic compounds such as citric, acetic and lactic acids, tartaric acid has one unreacted carboxyl group (COOH).

Commercial Production of Tartaric Acid

Tartaric acid, a white crystalline organic acid, can be produced through natural and synthetic routes. The natural route involves the recovery of the reddish precipitated salt, potassium bitartrate, from argol, the sediment in wine vats. On the other hand, the synthetic chemical route involves the production of the racemic mixture of tartaric acid from maleic anhydride.

Naturally occurring tartaric acid is found in a wide variety of plants and microorganisms, with the highest abundance in tamarind, grapes, bananas, apples, and Gymnema sylvestre. Its salt, potassium bitartrate, also known as cream of tartar, develops naturally during the fermentation process. This salt is often mixed with sodium bicarbonate and sold as baking powder, used as a leavening agent in food preparation. Tartaric acid itself is added to foods as an antioxidant (E334) and to impart its distinctive sour taste.

The competition between natural and synthetic tartaric acids is primarily based on price, with synthetic tartaric acid being the cheaper option. However, natural tartaric acid is still widely used in the food and wine industry due to its organic nature and presence in various fruits and plants.

Commercially, tartaric acid is available as a colorless to white translucent fine crystals or granular crystalline powder. It is a solid material under room conditions of temperature and pressure, mainly due to its very high melting point of 170°C.


  • Flavour enhancer (particularly in lime and grape-flavored beverages)
  • Chemical leavener
  • Anti-caking agent
  • Firming agent
  • Humectant
  • Acidulant (helps reduce the pH of wine or juice, but not below pH 3.0)
  • Antimicrobial or pH control agent, although to a lower extent than citric and other food acids
  • Formulation and processing aid

Tartaric Acid Application

Tartaric acid has various applications across different industries. Some of its main applications include:

  1. Food and Beverage Industry: Tartaric acid is commonly used as a flavoring agent in the food and beverage industry. It is also used as a preservative in some food products, including jellies, jams, and fruit juices.
  2. Wine Industry: Tartaric acid is a natural byproduct of the wine-making process and is often added to wines to enhance their flavor and acidity. It also helps to prevent the precipitation of wine crystals.
  3. Pharmaceutical Industry: Tartaric acid is used in the pharmaceutical industry as a component of effervescent salts, which are used in antacids and other medications.
  4. Cosmetics Industry: Tartaric acid is used in some cosmetics and personal care products, including shampoos and facial cleansers, as a pH adjuster and to improve the texture of the product.
  5. Other Applications: Tartaric acid has other applications, including as a chemical intermediate in the production of some organic compounds and as a chelating agent in some industrial processes.
