| Abstract: | The methods determing the groups in the modified starch have been developed, that is acidimetry for the basicity of acidified starch, complexing titration for the substitution degree of carboxymethyl starch, and heat paste titration and carbonyl process respectively for the carboxyl and nitrogen of oxidized starch. The simple and accurate processes have been used practically with satisfactory results. |
