Abstract: Factors affecting the anti-retrogradation and viscosity of corn starch phosphate with NaH2PO4 esterification were studied.The results showed that the anti-retrogradation increases and the viscosity decreases with the levels of esterification, reaction temperature and reaction time.The optimal conditions for corn starch phosphate preparation are:amounts of NaH2PO4, 5%,reaction temperature 130℃,and reaction time 4h.The phosphate corn starch can be used in ginger paste and bring in good texture.

Key words: phosphate starch, starch, ginger paste
