| Abstract: | Esterified starch with low degree of substitution was prepared with potato starch as raw material and vinyl acetate as esterifying agent. Influence of various factors on the substituting degree of products was studied. By orthogonal test, the optimum preparation conditions were confirmed as follows： pH 10.5 - 11.5, the reaction temperature 26 ℃, the reaction time lh and the dosage of esterifying agent 1.5 g. |
