Influence of the concentration of polyols on the rheological and spectral characteristics of guar gum

► The polyols raised the apparent viscosity of the solutions with 0.1 and 0.5% guar. ► The Newtonian plateau was detected in the guar/polyol systems. ► The viscoelastic behavior of gum was strongly influenced by polyol concentration. ► Guar 0.5% with polyol systems were not influenced by the freezing process.
