Starch, hydrogen phosphate acetate

Chemical properties

White powder. The viscosity is stable at high temperature and low pH value, the degree of retrogradation of paste liquid during freezing process is low, and the freezing resistance stability is high. Solubility, swelling power and transparency were significantly improved compared to native starch.

The Uses of Starch, hydrogen phosphate acetate

Acetylated distarch phosphate can improve water retention, increase meat tenderness and improve taste, and is not affected by high and low temperature.

Synthesis

Acetylated distarch phosphate is formed by esterification of sodium trimetaphosphate or phosphorus oxychloride with acetic anhydride (≤10%) or vinyl acetate (≤7.5%) and starch.
