Application:
DL-Tartaric Acid is widely used in many fields such as foodstuff, medicine, chemical industry and light industry etc., and is mainly used to make tartrates (tartaric acid salts), like antimony potassium tartrate, potassium sodium tartrate. It can be served as beer vesicant, foodstuff sourness agent and flavoring etc. Its sourness is 1.3 times of that of citric acid, and is especially suitable to be a sourness agent of grape juice. It is also very important for the tannage, photograph, glass, enamel and telecommunication equipment industries.
Packing& Storage:
