Natriumpyrofosfaat

Natriumpyrofosfaat, also known as tetranatriumpyrofosfaat, is an inorganic compound with the chemical formula Na4P2O7. It is the sodium salt of pyrophosphoric acid. In its anhydrous form, it appears as a white, crystalline powder. It is soluble in water, forming an alkaline solution.

This compound is widely used in various industries due to its properties as a buffering agent, emulsifier, dispersant, and sequestrant. In the food industry, it is often designated as E450(vi) and functions as a leavening agent in baked goods, a stabilizer in dairy products, and a texturizer in processed meats and seafood. It can also help to prevent discoloration in some foods.

Beyond food applications, natriumpyrofosfaat finds use in detergents as a water softener and builder, aiding in the removal of stains. It is also employed in metal treatment, textile processing, and as a component in toothpaste to help prevent tartar buildup. Its ability to chelate metal ions makes it valuable in applications where metal contamination is a concern. It is generally considered safe for its intended uses, with regulatory bodies setting limits for its incorporation into food products.
