Food

 Emulsifier raw materials

L(+)-tartaric acid is the major raw material of food emulsifying agent DATEM - diacetyl tartaric acid ester of mono diglycerides. DATEM has powerful effect on functions like emulsification, dispersion and anti-aging, which can effectively enhance the elasticity and ductility of dough. It is also widely used in bread, biscuits, cereals, cream and other products.

Beverage

Acidulants

L(+)-tartaric acid, as an acidulant and PH regulator, is widely used in beverages, sweets and other products to increase the flavor and adjust the acidity and taste of food.

Pharmaceuticals

Resolving Agent

D(-)-tartaric acid has many irreplaceable roles in medicine, chemical industry and light industry. It is mostly used in medicine as a resolution agent in the synthesis of products.

Construction

 Retarder

In the field of plasters and cements, fine powder L(+)-Tartaric acid is used as a set retarder to prolong the setting time of the concrete, so that the fresh concrete can maintain its plasticity for a long time.

Metal

Metal Polishing Agent

L(+)-tartaric acid and DL tartaric acid can be used as metal surface treatment agents to remove oxide film and rust spots.
