Rheological parameters of "Totapuri" mango juice were evaluated using rotational viscometer at temperatures 20, 30, 40, 50, 60 and 70 degrees C; and at concentrations of 5.17%, 8.51%, 12.38%, and 17% total solids. The power law model was fitted to the experimental results'. The value of flow behaviour index (n) was less than unity (0.24-0.41) at all temperature and concentrations indicating the shear thinning (pseudoplasticity) nature of the juice. Arrhenius model was able to relate the consistency index, in the range of 2.22-385.24 P s(n) with absolute temperature. Consistency index related to solid concentration by a power equation. The activation energies were found in the range of 1.66-11.35 kJ/mol K. (c) 2005 Elsevier Ltd. All rights reserved.
