Sodium Acid Pyrophosphate or Disodium Pyrophosphate is included in the phosphate group chemicals. It is one of the edible phosphorus salts that prevents food coloring and helps the fermentation process in foods. It is also generally called Disodium Diphosphate. Sodium Acid Pyrophosphate E Code = E 450
It is an anhydrous chemical substance in the form of an odorless, colorless white powder or granule. Tetra Sodium Pyrophosphate (TSPP) is known as a normal component of human body fluids. It is used extensively in many foods. It is an inorganic phosphate salt.
It has many uses in the industry due to its food preservative properties from cleaning products. It is also called as Sodium Tripolyphosphate (STPP), pentasodium salt and triphosphoric acid. Its chemical structure consists of 5 Sodium Atoms, 3 phosphorus atoms and 10 Oxygen atoms. Sodium Tripolyphosphate E Code is; E 450.
Sodium hexametaphosphate (SHMP) is a hexamer of the composition (NaPO3) 6. The sodium hexametaphosphate of commerce is typically a mixture of polymeric metaphosphates of which the hexamer is one, and is the compound usually referred to by this name. More correctly called sodium polymethanephosphate.
