dikalciumfosfát

Dikalciumfosfat, also known as calcium hydrogen phosphate or E341(ii) when used as a food additive, is an inorganic salt with the chemical formula CaHPO4. It is a naturally occurring mineral and is found in bones and teeth. Dikalciumfosfat exists in several hydrated forms, with the dihydrate (CaHPO4·2H2O) being the most common. It appears as a white powder or crystalline solid and is generally insoluble in water.

In the food industry, dikalciumfosfat serves multiple purposes. It is widely used as a leavening agent in baking, reacting with baking soda to produce carbon dioxide gas, which causes doughs to rise. It also functions as a dough conditioner, improving the texture and consistency of baked goods. Furthermore, dikalciumfosfat is employed as an anticaking agent, preventing powdered food products from clumping together. It can also act as a nutrient supplement, providing a source of calcium and phosphorus, essential minerals for bone health.

Beyond its food applications, dikalciumfosfat is utilized in pharmaceuticals as an excipient, serving as a binder or filler in tablets and capsules. It is also found in toothpaste as a polishing agent and a source of calcium to aid in remineralization. In agriculture, it is a component of some fertilizers, supplying phosphorus and calcium to plants. The production of dikalciumfosfat typically involves the reaction of phosphoric acid with calcium carbonate or calcium hydroxide.
