Cream tartar, whose chemical formula is KC4H5O6 and is called potassium bitartarate, is the salt of tartaric acid.Tartaric acid is the basic acid of the grapes and it constitutes the majority of the total acidity of these fruits. It is a odorless, acidic taste in the form of white crystalline powder. It is the salt-shaped organic precipitate of tartaric acid found in grapes.
Production and Reactions
Potassium bitartrate is formed by precipitating potassium by adding to tartaric acid during fermentation and resting. Cream tartar is produced by the purification of potassium and tartaric acid at the bottom of the wine barrels during the wine making. Production of baking powder can be carried out using the specified amounts. 8x Baking Powder = 2x Unit Carbonate 5x Cream Tartar
It is used as an additive in confectionery products. It is used to increase the function of baking powder used during the production of the cake. .
Potassium sodium tartrate obtained from cream tartar is used as mordant in this sector.
Iron and Steel
It is used in tinning process and surface polishing function in this sector.
