In the present study, the rheological behavior of commercial concentrated orange juice was reported. Thermo physical properties of concentrated orange juice such as density and viscosity variation with temperature and concentration are modeled. The concentrated orange juice (COJ) samples are assumed to be Newtonian fluids with a considerably high viscosity. The simple exponential power model fit well for the viscosity and concentration data. The exponential model described the effect of temperature on the apparent viscosity and the consistency index of the power law model. It was found that the viscosity and concentration increased exponentially with concentration.
