our DCP is pure white color, instead of off-white or yellow or grey color.
our P is 18.0%,instead of 17.0-17.5%,popular in domestic market.
our DCP has no smell.
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.
