The effect of pectin on the flow properties of mango pulp concentrates was studied using a coaxial cylindrical viscometer in the temperature (T) range 303‐343°K. The variables were soluble solid content(C) 16‐30°Brix, pectin content (C pec , range 0.0323‐0.0349 dry wt fraction) for the shear rate (γ) range 9.0‐250 s ‐1 . Mango pulp concentrates behaved as pseudoplastic fluids in the entire pectin content range with a flow behaviour index of 0.286. A model relating shear stress (s̀) with the above variables is presented:
