General Information
Calcium dihydrogen phosphate (food additive E341(i)) is a subtype of E341 (calcium phosphates). It is an acidic salt of calcium and orthophosphoric acid with the chemical formula Ca(H2PO4)2. In industry, this compound is also known as dicalcium phosphate or monocalcium phosphate.
The production of additive E341(i) involves the neutralization of orthophosphoric acid with calcium compounds such as calcium carbonate or calcium hydroxide in a stoichiometric ratio that ensures the formation of a monobasic salt. The resulting product is a white crystalline powder, easily soluble in acids and moderately soluble in water.
Monocalcium phosphate has mild alkaline properties and is capable of regulating the pH level in various environments. Upon heating, additive E341(i) gradually loses water and converts into pyrophosphates. It also serves as a readily available source of calcium and phosphorus for the human body.
In the food industry, additive E341(i) is used as an acidifier, leavening agent, and calcium source. It is commonly added to bakery products to improve dough structure and create a porous texture. Additionally, E341(i) is included in baking powders, powdered milk formulas, and baby foods. Thanks to its moisture-retention properties, monocalcium phosphate is also used in confectionery products to prevent them from drying out.
