| Abstract: | Use triethylamine as catalyst,gallic acid to modify konjac glucomannan（KGM）by esterification reaction,the optimum conditions were as follows：m（KGM）∶ m（triacetyl galloylchloride） was 1∶ 2 under the conditions of 50 ℃,and reaction time was 3.0 h.Triacetyls in the modified product could be partly removed by using sodium acetate method and the total yield was 57.9%. |
