Characterization of non-linear rheological behavior of SPI-FG dispersions using LAOS tests and FT rheology

► LAOS test was used to generate the nonlinear stress response. ► The Fourier transform rheology was used in analyzing the nonlinear behavior. ► Flaxseed gum strongly affected the deformation of nonlinear stress response curve. ► Flaxseed gum significantly altered magnitude of higher harmonic curve.
