What is Tartaric Acid

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. For more information or access to high-quality tartaric acid from a trusted specialty and chemical distributor, contact Brenntag North America. 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.
