The rheological behaviour of vinasses derived from sugar cane was studied as a function of time (0 and 600 s),soluble solids content (44 and 60 °Brix), temperature (10 and 50°C), and shear rate (0.33 and 1.0 s^-1). The results indicated that vinasses were time-independent at 25°C, where shear stress values ranged between 0.01 and 0.08 Pa. Flow curves showed a shear-thinning rheological behaviour in vinasses with a flow behaviour index between 0.69 and 0.89, for temperature between 10 and 20°C. With increasing temperature, the flow behaviour index was modified, reaching values close to 1.0. The Arrhenius model described well the thermal activation of shear stress and the consistency coefficient as a function of temperature. Activation energy from the Arrhenius model ranged between 31 and 45 kJ mol^-1. Finally, the consistency coefficient as a function of the soluble solids content and temperature was well fitted using an exponential model (R² = 0.951), showing that the soluble solids content and temperature have an opposite effect on consistency coefficient values.
