Dipotassium phosphate (K2HPO4) (also dipotassium hydrogen orthophosphate;Dipotassium phosphate dibasic) is the inorganic compound with the formula K2HPO4.(H2O)x (x = 0, 3, 6). Together with monopotassium phosphate (KH2PO4.(H2O)x), it is often used as a fertilizer, food additive, and buffering agent.[1] It is a white or colorless solid that is soluble in water.

It is produced commercially by partiial neutralization of phosphoric acid with two equivalents of [potassium chloride]]:[1]

H3PO4 + 2 KCl → K2HPO4 + 2 HCl
Uses
As a food additive, dipotassium phosphate is used in imitation dairy creamers, dry powder beverages, mineral supplements, and starter cultures.[2] It functions as an emulsifier, stabilizer and texturizer; it also is a buffering agent, and chelating agent especially for the calcium in milk products..[3]

As a food additive, dipotassium phosphate is categorized by the United States Food and Drug Administration as generally recognized as safe (GRAS).[

Potassium hydrogenphosphate, also called dipotassium orthophosphate, dipotassium hydrogenphosphate or dipotassium phosphate, is a salt of formula (K22 + HPO42-).

Role in organic farming
Potassium hydrogenphosphate: is a source of minerals and helps maintain isotony
 
Potassium hydrogenphosphate is often used by athletes, in fact, we can notice that unlike phosphoric acid, the pKa3 of the acid being very low, the acidity rate in the stomach will not fluctuate . Thus, some athletes use it so that the phosphate ion plays an important role in the cycle of energy transport, by ATP; this molecule will therefore promote the creation of ATP.

Potassium hydrogen phosphate (K2HPO4) (also dipotassium hydrogen orthophosphate; dibasicDipotassium phosphate) is the inorganic compound with the formula K2HPO4. (H2O) x (x = 0, 3, 6). Along with monopotassium phosphate (KH2PO4. (H2O) x), it is often used as a fertilizer, feed additive and buffering agent. [1]

A solution of dipotassium phosphate is formed by stoichiometric reaction of phosphoric acid with two equivalents ofDipotassium hydroxide:

H3PO4 + 2 KOH → K2HPO4 + 2 H2O
Uses
As a food additive,Dipotassium hydrogen phosphate is used in imitation dairy creams, dry powdered drinks, mineral supplements, and starter cultures. [2]

As a food additive,Dipotassium hydrogen phosphate is classified by the United States Food and Drug Administration as generally recognized as safe (GRAS).

30 L Fermentation of rhKGF2
The glycerol strain was recovered by seeding at a ratio of 1 to 100 to the LB medium and rotating at 200 rpm at 37 ° C. When the absorbance at 600 nm of the culture reached 0.8 to 1 , 0, cell amplification was performed by transferring 25 mL of culture into 250 mL of the modified medium composed of 10 g / L of tryptone, 10 g / L of yeast extract, 1.0 g / L ofDipotassium dihydrogen phosphate , 3 g / L of dipotassium hydrogenphosphate, 4 g / L of sodium chloride, 0.5 g / L of glucose, pH 7.2, and incubation with agitation at 180 rpm at 37 ° C for 8 to 10 h. The culture was transferred in a ratio of 1 to 10 to a 30 L fermenter containing fermentation medium (23 g / L of tryptone, 23 g / L of yeast extract, 5 g / L of sodium chloride, 1.0 g / L ofDipotassium dihydrogen phosphate, 3.0 g / L of hydrogen phosphate dipotassium phate, 0.5 g / L of ammonium chloride and 2 g / L of glucose). During the cultivation process, 20% ammonia solution was used to maintain the pH between 6.9 and 7.0, and the oxygen level was not less than 30% by regulating the flow rate of 'glucose supply, ventilation and rotational speed. When the cells grew to mid-log phase, lactose used as an inducer was added to the culture, and its concentration was maintained by feeding lactose. During the incentive period, the pH was maintained between 6.9 and 7.0 and the oxygen level above 30%
