Tartrate (tartaric acid), ie, 2,3 - dihydroxy 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.
