Abstract:
The apparent viscosities of the Opuntia fícus indica pulp with addition of different concentrations of
maltodextrin (10, 15 and 20%) were determined. The experimental data were submitted to the
variance analysis and the averages compared by test Tukey at 5% probability. Linear and quadratic
equations were fitted to the apparent viscosity in function of temperature. It was verified that the
apparent viscosity of the samples decreased with the increase of the rotation speed and with the
increase of the temperature. The increase of the maltodextrin concentration resulted in the increase of
the apparent viscosity. Linear and quadratic equations can be used to represent the apparent viscosity
of the Opuntia fícus indica pulp in function of the temperature, with determination coefficients (R2) up
to 0.77 and mean relative deviation modulus (P) lower than 10%.
