Tetrasodium pyrophosphate (TSPP), also called tetrasodium disphosphate or sodium pyrophosphate, is a synthetic ingredient that can be used as an acid regulator, sequestrant, protein modifier, coagulant, and a dispersing agent in food with the European food additive number E450(iii). It is gluten free and vegan
TSPP can be produced by the neutralization of phosphoric acid with sodium hydroxide with mol proportions of 2:1.
Food grade TSPP exists as two forms, and follows the corresponding chemical formula:
|Appearance||white powder or granular powder|
|Solubility||Soluble in water, insoluble in ethanol|
With the properties of chelating metal ions, increasing protein water holding capacity, PH buffering, stabilization, emulsification, casein thickening and ect, tetrasodium pyrophosphateis widely used in food to improve the gel strength and the tenderness of meat products/analogs.
Also, it is used with other phosphates (e.g. sodium hexametaphosphate, sodium acid pyrophosphate) in seafood to increase the water retention.
Food grade TSPP is mainly used in following two functions:
Following food list may contain TSPP:
Orally the main purpose of TSPP is to prevent the formation of calculus by reducing the deposition of calcium and magnesium on teeth. Thus it is commonly used as the anticalculus component of many tartar-control toothpastes and mouth rinse. Disodium pyrophosphate also has the same function.
The top toothpaste manufacturer, Crest also uses it as the anti-tartar ingredient in its whitening expressions.
