Abstract: 
The work describes dextrin modifications with the purpose to obtain a functional product with an extensive structure of macromolecules, capable to form self-stabilized dispersions in an aqueous environment. To ensure the branching, the modification was performed using the functional agents – N-derivatives of glutamic acid. The substitute in the N-position provides the introduction of the required function. Modification was performed by using the Steglich reaction that provides the progress of the process in soft, controlled conditions.
