 Tartaric acid is a carboxylic acid, present in many plants, such as grapes and tamarind, is the major organic acids in wine one. Added as a food antioxidant, can make the food with acidity. Use of tartaric acid is the largest beverage additives. Is the pharmaceutical industry raw materials. In the mirror industry, tartaric acid is an important agent and reducing agent, the formation of silver mirror can control the speed, get a very uniform coating.

 Tartaric acid, also known as 2,3 - dihydroxybenzoic acid. Structure Simple HOOCCH (OH) CH (OH) COOH. The presence of potassium hydrogen tartrate in grape juice, the salt is insoluble in water and the alcohol, grape juice wine in the process of precipitation, known as tartar, tartaric acid and the resulting name. Tartaric acid exists mainly in the form of potassium in a variety of plants and fruits, is also a small amount of free states exist.
