Influence of different purification and drying methods on rheological properties and viscoelastic behaviour of durian seed gum

► Durian seed gums showed the pseudoplastic (shear-thinning) flow behaviour. ► The purification using isopropanol and ethanol led to induce the highest viscosity. ► Durian seed gums exhibited more elastic behaviour than the viscous behaviour (G′ > G″). ► The freeze-dried gum provided the highest and lowest viscous modulus (G″). ► Purification using saturated barium hydroxide could provide the most desirable rheological properties.
