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

1. Better water solubility.
2. White free-flowing crystalline powder or white granular
3. DM STPP 107 has salient chelating capacity to ions of Ca, Mg etc.
4. DM STPP 107 is a surfactant which has outstanding emulsification for lubricants and fat.
5. 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.
6. 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.

Applications
DM STPP 107 may be used to improve the eating quality in food processing, especially in meat and fish products. In meat processing, mainly used in water retention, emulsification stability, juiciness and tenderness; Delaying the rate of oxidative spoilage; Improving color and maintaining flavor
It is also applied in pet food (e g. cat and dog food) for the purpose of binding water and keeping the animal feed fresh.

Delivery Form
White powder or granular.         

Packaging
DM STTP 107 is supplied in 25 kg bags / 1.000 kg shrink-wrapped pallets.

Storage
DM STTP 107 is non-hygroscopic. However, when stored in open container, the product can still absorb small amounts of moisture owing to the high surface area of the powder.It is in sealed containers at room temperature in a dry place. Partially emptied containers should be carefully resealed after use.
Minimum shelf life is 24months from the date of shipping when stored according to the said conditions.
