Comparing E450VII - Calcium dihydrogen diphosphate vs E451 - Triphosphates

Overview

E450VII - Calcium dihydrogen diphosphate

Calcium dihydrogen diphosphate (E450VII) is a calcium salt of pyrophosphate used mainly as a leavening acid and dough conditioner. It helps baked goods rise evenly and keeps texture stable during mixing, freezing, and baking. You may also see it called calcium acid pyrophosphate on ingredient lists.

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.

Popular questions

  1. What is calcium acid pyrophosphate?

    It’s the food additive E450vii (calcium dihydrogen diphosphate), a calcium phosphate salt used mainly as a leavening acid in baking powders and doughs. It also functions as a stabilizer and sequestrant (and can aid emulsification) in various processed foods.

  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.
