MANUFACTURING OF POTASSIUM TARTRATE:
Potassium tartrate is produced by the reaction of tartaric acid with potassium sodium tartrate (rochelle salt), and potassium sulfate, followed by filtration, purification, precipitation and drying.
USES AND APPLICATIONS OF POTASSIUM TARTRATE:
• OENOLOGY:
Potassium tartrate is Used to decrease the acidity of wines.
Since Potassium tartrate is a tartaric salt, Potassium tartrate respects the composition of the wine better than any other neutralizer.
• Pharmaceuticals Industry
• Cosmetics Industry
• Laboratory Reagent
Manufacture of potassium salts, medicine (cathartic), lab reagent.
Potassium tartrate is the acid potassium salt of tartaric acid occurring as crystals or powder.
Potassium tartrate is relatively poorly soluble having a solubility in 100 ml of water at 0.8 g at 25°c and 6.1 g at 100°c. A 1% solution at 30°c has a ph of 3.4.
Chemical names are potassium acid tartrate, potassium hydrogen tartrate, and potassium bitartrate. Potassium tartrate functions to complex with heavy metal ions and to regulate ph; Potassium tartrate can have a gentle laxative action if given at adequate levels.
The acidulant is used in chemical leavening to release carbon dioxide which produces the loaf volume.
Potassium tartrate has limited reactivity in the cold so when used in reduced-temperature batters Potassium tartrate has little gas evolution during the initial mixing.
At room temperatures, Potassium tartrate has a relatively fast reaction rate.
Potassium tartrate functions as a taste regulator in sugar icing and in controlled crystallization of toffees and fondants by the regulated inversion of sucrose.
Potassium tartrate is used in baked goods, crackers, candy, and puddings.
The analysis can be used as an agent in a variety of applications, including the preparation of microbiological culture media and the pharmaceutical industry.
Potassium tartrate is widely used in a variety of industries, including food, medicine, the chemical industry, and the lighting industry.
Potassium tartrate is primarily used to make tartaric acid salts such as antimony potassium tartrate and tartaric acid potassium, sodium, and other tartaric acid salts.
In the food industry, potassium tartrate is used as a beer foaming agent, a sour agent, a flavour masking agent, and in other applications
When combined with acids such as lemon juice, potassium tartrate is widely used in a variety of household applications, particularly in the culinary and metal-cleaning industries.
Because of their acidic nature, potassium tartrate and bitartrate salts are widely used in industry as pH regulators.
Health and safety ramifications: Because the risks associated with its manipulation are minimal, potassium tartrate is a substance that can be handled with normal caution.
