Potassium bitartrate, also known as potassium hydrogen tartrate, is a byproduct of winemaking. In cooking it is known as cream of tartar. It is the potassium acid salt of Tartaric Acid (a carboxylic acid). It can be used in baking or as a cleaning solution (when mixed with an acidic solution such as lemon juice or white vinegar).
Potassium tartrate is used in the manufacture of Tartaric Acid salts, such as antimony potassium tartrate and potassium tartrate, etc.
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.
It also plays an important role in tanning, photography, glass, enamel, telecommunications equipment and other industries.
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.
