Monopotassium phosphate (MKP) is a highly purified inorganic salt produced by reacting phosphoric acid with potassium hydroxide or potassium carbonate. It is highly soluble in water and provides both potassium and phosphorus in a readily available form.

In the food industry, MKP is used as a buffering agent, sequestrant, and yeast nutrient in various applications. It functions as an effective emulsifying salt and is valued for its low sodium content in reduced-sodium food formulations. MKP is widely used in sports beverages, nutritional supplements, and fermentation processes as a mineral source.
