Abstract: The rheological behavior of an aqueous solution composed of 65% sucrose and 0.1% CMC was experimentally determined from -10C to 50C using a rotational viscometer equipped with coaxial cylinders. The model solution behaved as pseudoplastic fluid, represented by the power-law model. Flow behavior and consistency indices determined at -10.1, 0.5, 9.8, 19.0, 30.1 and 50.0C, showed values between 0.79 to 0.86 and 0.15 to 10.22 Pa.s(n), respectively. The effect of temperature on the rheological parameters was represented by Arrhenius-type relationships, with R-2 greater than or equal to 0.97. They were compared to the rheological behavior of a concentrated orange juice with 65degreesBrix and 7% pulp content. The comparison of separate rheograms for both fluids showed that the model solution can be used to represent concentrated orange juice.
