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.
What is the formula for ammonium phosphate?
For E342, the ammonium phosphates used are monoammonium phosphate (NH4H2PO4) and diammonium phosphate ((NH4)2HPO4); the fully neutral (NH4)3PO4 is unstable and not typically used in foods.
Is monoammonium phosphate toxic?
It has low toxicity and is permitted as a food additive; within the group ADI for phosphates (e.g., EFSA: 40 mg phosphorus/kg body weight/day), normal food uses are considered safe. Very high intakes can disturb mineral balance, and people with kidney disease should manage phosphate intake.
Is ammonium phosphate toxic?
At permitted food levels, ammonium phosphates (E342) are considered safe, with a group ADI for phosphates set by EFSA at 40 mg phosphorus/kg body weight/day. Excessive intake may affect mineral balance and is a concern for those with impaired kidney function.
Is ammonium phosphate soluble in water?
Yes—both monoammonium and diammonium phosphate are readily soluble in water.
