Rheological and physical properties of spray-dried mucilage obtained from Hylocereus undatus cladodes

► The rheological behavior of reconstituted spray-dried mucilage was studied. ► The reconstituted mucilage exhibited non-Newtonian shear-thinning behavior. ► The steady-shear viscosity and dynamic response were correlated to the Cox-Merz rule. ► Mucilage recovers its elastic properties at concentrations of 7% and 8%. ► The viscous component G′′ predominated over the elastic component G′.
