our DCP's citric Acid P is 14%,instead of some Chinese's 3.4--9.66% ,which leads Chicken's Diarrhea or stone .

our DCP's Ar is 10ppm,European Standard.

the heavy metal of our DCP meet up with Chinese National Standard No:GB/T 22549-2008 for we do not use HCL/sulphoric acid watested from dyeing and pringting factory,other chemical industry factories.

our DCP is pure white without dark dots , those factories has no drying equipment and dry DCP in the open air road.

 

 

our DCP is produced strictly according to Chinese National Standard No:GB/T 22549-2008.Phosphorous in 2% citric acid is 14.0% min,
Some frauds' Phosphorous in 2% citric acid is 3.4--9.66% while Ca is 27-33% ,for they burn their rock phosphate by coal,instead of acidifying by sulphoric acid or hydrochloric acid HCL.their products are Tri Calium Phosphate TCP,instead of DCP.
