Dicalcium phosphate dihydrate (DCPD) is a calcium salt that is used in various industries, including food, pharmaceuticals, and agriculture. It is composed of two calcium atoms, one phosphate ion, and two molecules of water. DCPD is a white, odorless powder that is insoluble in water, making it an ideal ingredient for use in products that require a longer shelf life.

Unmilled dicalcium phosphate dihydrate refers to DCPD that has not undergone any milling or grinding processes. As a result, the particles are slightly larger and have a coarser texture compared to milled DCPD. It is also commonly used as a dietary supplement for humans, particularly those who are at risk of calcium and phosphorus deficiencies.

In the food industry, unmilled DCPD is used as a source of calcium and phosphorus in baked goods, beverages, and other food products. It is also used as an anti-caking agent, to prevent clumping of powdered ingredients.

In the pharmaceutical industry, unmilled DCPD is used as an excipient, to help bind and stabilize tablet formulations. It is also used as a source of calcium and phosphorus in oral supplements and medicines.

Overall, unmilled dicalcium phosphate dihydrate is a versatile ingredient that is used in a wide range of products, providing a source of calcium and phosphorus that is easily absorbed by humans.
