Applications
Tartaric Acid USP Food Grade also known as L+Tartaric Acid is mainly used as an food additive in many foods, such as soft drinks, bakery products, and candies. It also has many industrial uses like tanning, ceramics manufacture, and the production of tartrate esters for lacquers and textile printing. It acts as an intermediate to antitubercular drugs and a chiral reagent to prepare tartrate derivatives. It is used as a catalyst for resin finishing of polyester fabric, a resist agent in dyeing, an imaging agent in photography, a pH regulator for oryzanol synthesis, a cleaning and polishing agent of the metal surface, as a reductive agent in mirror manufacturing, in electroplating, sulfur removal, and acid pickling.
