Other name:
phosphosol;Potassiumpyrophosphate,anhydrous;Potassiumpyrophosphate,trihyd;pyrophosphatedepotassium;pyrophosphatetetrapotassique;pyrophosphoricacid,tetrapotassiumsalt;tetrapotassiumdiphosphorate;POTASSIUM DIPHOSPHATE EXTRA PURE
CAS: 7320-34-5
EINECS No.: 230-785-7
Formula: K4O7P2
Molecular Weight: 330.336522
Purity: 98%
Appearance: White powder
Type: Food grade
Anhydrous tetra potassium phosphate is in white powder or granular. Relative density 2.534 g/cm3 and melting point 1109°C; It is apt to absorb humidity in the open air to deliquescent; Soluble in water but insoluble in ethanol, and at 25°C,its solubility in water is 187g/100g water; It can chelate with alkaline metals ions or heavy metal ions.White powder or white granular; easily soluble in water.
In food industry, it is used as emulsifier, quality improver, chelating agent. It can be applied as fresh preserver, water conservation, and quality improver for quick-frozen aquatic products. Complex used with other phosphates in meat processing will get a better effect. Also it can improve the expansibility of ice cream, and the taste of flour and cake, prevent the cheese ageing.
