Dry process of preparation for white dextrin

With cornstarch as raw material and hydrochloric acid as catalyzer,the white dextrin is prepared with dry process.Through the experiments,the influences such as different acids,the quantity of the acid,reacting temperature,and reacting duration to the white dextrin quality are analyzed.The optimum technical indexes are fixed.The viscidity of the product shows that the rheology of the acid processed white dextrin is changed a lot.The result from the polarizing microscope indicates that the crystal structure of the starch was partly destroyed.
