Overview

E451 - Triphosphates

Triphosphates (E451) are salts of condensed phosphates used to keep foods moist, stable, and evenly mixed. They are common in processed meats and seafood, where they help bind water, protect texture, and prevent off-flavors from metal ions. Approval and use levels vary by country, but they are widely permitted for specific uses.

E452IV - Calcium polyphosphate

Calcium polyphosphate (E452iv) is a family of calcium salts made from chains of phosphate units. Food makers use it to hold moisture, help oil and water mix, and keep texture steady in many processed foods. It also goes by calcium metaphosphate.

Popular questions

What is adenosine triphosphate?
Adenosine triphosphate (ATP) is a biological energy-carrying molecule and not the food additive E451; E451 refers to inorganic triphosphates (e.g., sodium tripolyphosphate) used in foods as sequestrants and stabilisers.
What is sodium triphosphate?
Sodium triphosphate (sodium tripolyphosphate, STPP; Na5P3O10) is the E451 additive—an inorganic triphosphate used to bind metal ions, retain moisture, and improve texture in foods.
Which of the following statements about inositol triphosphate is false?
It’s false to claim that inositol triphosphate is E451 or used as a food additive; E451 is inorganic tripolyphosphate salts (e.g., STPP), not the cellular messenger IP3.
What are nucleoside triphosphates?
Nucleoside triphosphates (e.g., ATP, GTP) are biological building blocks of nucleic acids and energy carriers, not the E451 additive; E451 comprises inorganic triphosphate salts used as sequestrants and stabilisers in foods.
