Abstract: A number of systems capable of forming gels upon contact with an aqueous solution of NaCl, two components of which are represented by gellan and CaCl2, are studied. The third component is pullulan with different molar masses. Systems such as these could be used for medical purposes, particularly for the delivery and controlled release of drugs. The influence of the molar mass of pullulan on the rheology of the resulting gel is analyzed to optimize its viscoelastic properties. It is that reducing the molar mass of pullulan integrated into the gel composition improves the viscoelastic properties of the system. It is established that the gels obtained at room temperature during interaction with an aqueous solution of NaCl did not deteriorate when heated up to temperatures of ~60–70°C.
