Overview

E341 - Calcium phosphates

Calcium phosphates (E341) are a group of calcium salts of phosphoric acid used in foods mainly as leavening acids, anti-caking agents, and acidity regulators. They also serve as calcium sources for fortification and help stabilize powders and blends. In ingredient lists, you may see them as monocalcium phosphate, dicalcium phosphate, or tricalcium phosphate.

E544 - Calcium polyphosphate

Calcium polyphosphate (E544) is a member of the phosphate family used to stabilize texture, bind water, and control acidity in processed foods. It belongs to the broader “polyphosphates” group, which helps foods like processed cheese and cured meats hold together and stay moist.

Popular questions

How does calcium phosphate transfection work?
DNA is mixed with calcium chloride and then added to a phosphate buffer to form fine calcium phosphate–DNA precipitates that attach to cells and are taken up (endocytosis), delivering the genetic material. This is a lab technique and not a food use of E341.
What is mono calcium phosphate?
Monocalcium phosphate [Ca(H2PO4)2], designated E341(i), is an acidic calcium phosphate used as a leavening acid and acidity regulator in baking, and it is relatively water‑soluble.
What is dibasic calcium phosphate?
Dibasic (dicalcium) phosphate [CaHPO4], E341(ii), is a sparingly water‑soluble calcium phosphate used as an anti‑caking agent, buffering agent, and mineral fortificant.
Is calcium phosphate soluble in water?
It depends on the form: monocalcium phosphate is fairly soluble, dicalcium phosphate is sparingly soluble, and tricalcium phosphate is practically insoluble.
What is di calcium phosphate?
Dicalcium phosphate (dibasic calcium phosphate, CaHPO4), E341(ii), is a low‑solubility form used in foods as an anti‑caking agent and as a calcium/phosphate fortificant.
