Calcium phosphate is a family of materials and minerals containing calcium ions (Ca2+) together with inorganic phosphate anions. It is a key component of bone and teeth in the form of hydroxyapatite. In the food industry, calcium phosphate is used as a leavening agent, a nutritional supplement, and an anti-caking agent. It is commonly found in baking powders and is used to fortify cereals and other food products with calcium. Its role in food is primarily to provide calcium, an essential mineral for bone health, and to improve the texture and stability of food products. Calcium phosphate is slightly soluble in water, which limits its bioavailability, but it is insoluble in alcohol and fats.
