Tartaric acid
Function
1.Dl-tartaric Acid is colorless transparent prismatic crystal or white fine to coarse crystalline powder. It has aromas of grapes and white lemon. Dl-tartaric Acid CAS 133-37-9 tastes sour. Stable in air. No moisture absorption. The acidity is about 1.2 ~ 1.3 times that of citric acid.
2.Dl-tartaric Acid can be used as sour agent, antioxidant synergist, flavor enhancer, quick acting bulking agent, acidic substance, edible pigment dilution and curing agent. Dl-tartaric Acid is widely used in food, chemical industry, light industry and other industries.
