Comparing E451 - Triphosphates vs E450 - Diphosphates

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.

E450 - Diphosphates

Diphosphates (E450) are a family of phosphate salts that help baked goods rise, keep foods moist, and protect color and texture. On labels they appear under names like disodium diphosphate, sodium acid pyrophosphate, or tetrasodium diphosphate. They are common in baking powders, processed meats, and some seafood products.

Popular questions

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  1. What is sodium acid pyrophosphate?

    Sodium acid pyrophosphate (SAPP) is an E450 diphosphate salt used mainly as a leavening acid with baking soda and as a sequestrant to control color and prevent off‑reactions in foods like baked goods and potato or seafood products.

  2. What is tetrasodium pyrophosphate?

    Tetrasodium pyrophosphate (TSPP) is an E450 diphosphate salt used as a sequestrant, buffer, and stabiliser to bind metal ions and improve water retention and texture in foods such as seafood, processed meats, and some dairy products.

  3. Is sodium acid pyrophosphate bad for you?

    It’s generally recognized as safe at permitted food levels; EFSA sets a group ADI for phosphates of 40 mg phosphorus/kg body weight/day. People with kidney disease or on phosphate‑restricted diets should limit phosphate additives, which can add to overall phosphorus intake.

  4. What is adenosine diphosphate?

    Adenosine diphosphate (ADP) is a natural cellular molecule involved in energy transfer; it contains a diphosphate group but is not used as the food additive E450.

  5. What is pyrophosphate in food?

    In food, pyrophosphate (diphosphate, E450) refers to salts of P2O7 used as stabilisers, emulsifiers, sequestrants, thickeners, or leavening acids. Examples include sodium acid pyrophosphate and tetrasodium pyrophosphate, which help control leavening, bind metal ions, and improve texture or moisture retention.
