What is Tartaric Acid?
Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, especially grapes, bananas, tamarind and citrus fruits. Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally during the fermentation process. It is often mixed with sodium bicarbonate and sold as baking powder, which is used as a baking agent when preparing meals. The acid itself is added to foods as an antioxidant and gives it its distinctive sour taste. The E number is E334.
Tartaric acid is an alpha-hydroxy-carboxylic acid, diprotic and aldaric in acid properties, and is a dihydroxyl derivative of succinic acid.
How is Tartaric Acid produced?
The L – (+) – tartaric acid isomer of tartaric acid is produced industrially in very large quantities. It is obtained from sediments, which is a solid by-product of fermentations. The previous by-products consist mostly of potassium bitartrate (KHC4H4O6). This potassium salt is converted to calcium tartrate (CaC4H4O6) after treatment with milk of lime (Ca(OH)2).
In practice, higher yields of calcium tartrate are achieved with the addition of calcium chloride. Calcium tartrate is then converted to tartaric acid by treating the salt with aqueous sulfuric acid:

What are the uses (processes) of Tartaric Acid?
- It is used as an additive with antioxidant properties in the food industry with the code E334.
- It is used in the production of soda to give the sour taste to the soda.
- Tartaric acid is used to give a sour taste to various foods.
- Tartaric acid can be used to make the cakes rise during baking.
- During winemaking and fermentation, tartaric acid can be preferred to take advantage of its sour taste.
- It is used in some pastry products such as Turkish delight and whipped cream due to its thickening properties.
- Tartaric acid can be used for dyeing wool.
- Tartaric acid and its derivatives have been used in the manufacture of effervescent salts in combination with citric acid to improve the taste of oral medications. The potassium antimonyl derivative of the acid, known as an emetic of tartar, is included in small doses in cough syrup as an expectorant.
- Tartaric acid also has several applications for industrial use. It has been observed that the acid chelates metal ions such as calcium and magnesium. Therefore, the acid is used in the agricultural and metal industries as a chelating agent to complex micronutrients in soil fertilizer and to clean metal surfaces composed of aluminum, copper, iron and alloys of these metals, respectively.
