TECHNOLOGIES OF MODIFIED PREGELATINIZED STARCHES PREPARATION --Modified Pregelatinized Corn Starch Preparation

This paper mainly studied the technology of preparing modified α corn starch by an alcoholic-alkaline treatment,getting the optimum technical conditions, analyzing the properties of modified α corn starch such as viscosity, starch granule and DSC.It can be concluded that nodified α corn starch is a modified stach with high viscosity,keeping starch granules and cold water soluble
