Product application
Chemical engineering
Potassium tartrate is used in the manufacture of Tartaric Acid salts, such as antimony potassium tartrate and potassium tartrate, etc.
Food
It is used in the food industry such as beer foaming agent, food acid flavour agent, correction agent, etc. The acidity is 1.3 times of citric acid, especially suitable used as acidulant for grape juice. This product is identified by the FAO/WHO expert committee as an excellent food additive.
Light industries
It also plays an important role in tanning, photography, glass, enamel, telecommunications equipment and other industries.
Laboratory
It is also used for the determination of bismuth, aluminium and nickel; the preparation of microbiological media. It is also widely used in buffer solutions.
