Starch, phosphate

Chemical properties

White powder. The characteristics are that the gelatinization temperature decreases, the stability of the paste increases, it is not easy to age, and the freeze-thaw stability also increases. It can form complexes with trace metals such as iron, copper, nickel, and diamond in grease to delay oxidation.

The Uses of Starch, phosphate

Starch, phosphate can be used as thickener; stabilizer; binder. It is also used to preserve frozen food, and it has good shape retention after repeated freezing and thawing.

Synthesis

Starch, phosphate is made by washing and drying starch after esterification with orthophosphoric acid (or sodium phosphate or potassium phosphate) or sodium tripolyphosphate.
