Tartrate refers to a salt or ester derived from tartaric acid, a naturally occurring organic acid found in various plants, particularly in grapes. It is commonly used in the food and beverage industry, especially in winemaking, where it helps stabilize the wine and prevent crystallization. In addition to its culinary uses, tartrate compounds are also utilized in pharmaceuticals and as food additives. For example, potassium tartrate is often used as a leavening agent in baking, while sodium tartrate can serve as a buffering agent in various chemical applications.
