Natural Occurrence

Calcium phosphates are the main mineral component of bones and teeth. In nature, they exist primarily as hydroxyapatite. The forms used as food additives are synthetically produced for purity and consistency.

Manufacturing

Method: chemical synthesis

Produced by reacting phosphoric acid with calcium hydroxide, calcium carbonate, or calcium chloride. The molar ratio of reactants determines which form is produced: monocalcium phosphate (E341i, Ca(H2PO4)2), dicalcium phosphate (E341ii, CaHPO4), or tricalcium phosphate (E341iii, Ca3(PO4)2). Each form has different solubility and functional properties.

Applications Beyond Food

Cosmetics

Abrasive in toothpaste, opacifying agent, bulking agent.

Medical

Calcium supplement, tablet excipient, antacid, toothpaste abrasive.

Industrial

Animal feed supplements, fertilizers, polishing agents.

Household

Pet food supplements, plant fertilizer.
