Abstract: Selecting sweet potato starch as raw material, the factors of reaction efficiency such as reaction temperature, reaction pH value, reaction time and the consumption of acetic anhydride were investigated. Properties including expansibility, solubility, transparence, freeze-melt stability and degree of substitute (DS) were systematically studies. The structure of acetified starch was detected by FTIR spectrum.

Key words:  , sweet potato starch; acetic esterfication; property;
