Audited Supplier Tartaric acid is a naturally occurring organic acid that is found in various plants, particularly in grapes. It is a dicarboxylic acid, meaning it has two carboxyl groups (-COOH). The acid is named after tartar, a sediment that forms on the insides of wine barrels during the fermentation of grape juice. Tartaric acid plays a significant role in the fermentation process of grapes and is a key component in the production of wine.
Chemically, tartaric acid has the molecular formula C4H6O6, and its structure includes four carbon atoms, six hydrogen atoms, and six oxygen atoms. The acid is often used in the food and beverage industry as an acidulant, providing a sour taste. Apart from its use in winemaking, tartaric acid is also used in baking powders to activate the leavening agent and prevent the formation of crystals in sugar syrups.
Tartaric acid has several isomers, including d-tartaric acid and l-tartaric acid, which are optically active and exist in mirror-image forms. These isomers have different optical properties and can be separated from each other. Overall, tartaric acid is a versatile compound with various applications in both the culinary and industrial fields.
