Weight: 1 pound
Sale price$34.00


Dipotassium Phosphate Anhydrous, also known as Dipotassium Hydrogen Phosphate, is a highly soluble, white, granular or powder product that is produced commercially by partial neutralization of phosphoric acid with two equivalents of potassium chloride.

Dipotassium Phosphate Anhydrous is known for its excellent buffering capacity, alkalinity, and nutrient source capability. It is a colorless or white square crystal granule or powder that is easily deliquescent and insoluble in ethanol. The product has a pH value of approximately 9 in a 1% aqueous solution. It interacts with milk proteins to promote emulsification.

Dipotassium Phosphate Anhydrous is widely used in the food, pharmaceutical, and fermentation industries. In the food industry, it is an excellent buffer for casein-based coffee creamers, stabilizing the protein layer around fat droplets, and preventing syneresis and curdling of the protein when added to hot, acidic coffee or tea. It also serves as a mineral supplement in pharmaceuticals and a nutrient source during yeast production and other fermentation processes. Additionally, it helps buffer the pH of cheese and has applications in molecular biology, biochemistry, and chromatography. The product can be used as a buffering agent, chelating agent, yeast food, emulsifying salt, and synergistic agent of anti-oxidation in the food industry.
