Kaliumcittraatti

Kaliumcittraatti, also known as potassium citrate, is a potassium salt of citric acid with the chemical formula K3C6H5O7. It is a white, crystalline powder that is odorless and has a saline, slightly tart taste. Kaliumcittraatti is highly soluble in water.

In its pure form, kaliumcittraatti is a crystalline solid. It is commonly encountered as a food additive, where it serves as a preservative, acidity regulator, and emulsifier. Its E number is E332. In the food industry, it is used in various products including jams, jellies, ice cream, and processed cheeses.

Medically, kaliumcittraatti is used to treat or prevent urinary tract infections and to prevent kidney stones. It works by increasing the pH of the urine, making it less acidic, which helps to prevent the formation of certain types of kidney stones, such as uric acid stones and cystine stones. It is also used as a potassium supplement in cases of hypokalemia, a condition characterized by low potassium levels in the blood.

Kaliumcittraatti can be produced by reacting potassium carbonate or potassium bicarbonate with citric acid. The reaction yields potassium citrate and water, with carbon dioxide being released if a bicarbonate is used. It is generally considered safe for consumption when used as a food additive within established limits.
