| Abstract: | The conditions for the carboxymethylation modificationof Konjak glucomannan(KGM) were studied.Through analyzing the effects of NaOH dosage,the dosage of chloroactic acid,reaction time and reaction temperature,etc.on the substitution degree,the optimum condictions for the carboxymethylation of KGM were confirmed.Moreover,the thermal stability of modified KGM and non-modified KGM and the viscosity and stability of hydrosol were compared. |
