Flow characteristics of juice of “Totapuri” mangoes Original Research Article

Rheological parameters of “Totapuri” mango juice were evaluated using rotational viscometer at temperatures 20, 30, 40, 50, 60 and 70 °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 sn 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.
