Product Description

Food Additives DM STPP 107 Edition Date May28,2018 Edition Number 2 Product Description DM STPP 107 (E451(i)) is the sodium salt of the polyphosphate penta-anion. It is white powder or granular. Its' melting point is 622°C.It is easily soluble in water.
Benefits Better water solubility. White free-flowing crystalline powder or white granular DM STPP 107 has salient chelating capacity to ions of Ca, Mg etc. DM STPP 107 is a surfactant which has outstanding emulsification for lubricants and fat. DM STPP 107 has different bulk density, i e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3. DM STPP 107 has two kinds of crystalline forms, namely Phase I (of high temperature) and Phase II (of low temperature). The chemical characters of the two types are the same, and the difference between them lies in the thermo stability. Specifications
