Description Effects of pectinase (polygalacturonase; Novo Pectinex 3XL, Novo Nordisk Ferment Ltd.) treatment on rheological properties of mango (var. Totapuri) pulp were investigated using response surface methodology together with a second order central composite rotatable design. Reactions were performed for different times (30-150 min) and at different temp. (25-60C) using various enzyme concn. (0.005-0.095%). Both raw and pectinase-treated pulp behaved as pseudoplastic liquids and exhibited yield stress. Shear rate and shear stress data of enzyme treated and untreated pulp were fitted well by the Herschel-Bulkley model (r <greater than or equal to> 0.991, P <less than or equal to> 0.01). Flow behaviour index of pulp increased with increasing time of pectinase treatment and/or with increasing pectinase concn. whereas apparent viscosity decreased with increasing enzyme concn.
