General Information
Tricalcium phosphate (food additive E341(iii)) is one of the subtypes of E341 (calcium phosphates). It is a tribasic calcium salt of orthophosphoric acid with the chemical formula Ca3(PO4)2, also known as tricalcium phosphate.
Additive E341(iii) is produced by reacting orthophosphoric acid with calcium oxide or lime milk in controlled proportions to ensure the formation of a tribasic salt. Natural sources of tricalcium phosphate include apatite group minerals and phosphorites, which are used for industrial-scale production.
Tricalcium phosphate is a fine white odorless powder that is practically insoluble in water but dissolves in acids. It is heat-stable and non-hygroscopic, making it a convenient component in dry powder mixtures.
In the food industry, additive E341(iii) is widely used as an anti-caking agent in dry products (milk powders, spices, icing sugar) and as a calcium source for fortifying food. Due to its chemical inertness and neutral taste, tricalcium phosphate is effectively used in baby food, sports supplements, and dietary products.
In baking, it serves as a component in leavening agents for dough, while in processed cheese production it functions as a texture stabilizer and emulsifier.
Outside the food sector, tricalcium phosphate is used in toothpaste as a mild abrasive, as well as in the production of pharmaceuticals and animal feed supplements.
