Viscosity of crude rice bran oil with the wax content of 0.23–8.60 (% wt/wt) was measured using a coaxial cylindrical viscometer in the temperature range of 297–333 K. The crude oil behaved like pseudoplastic fluid obeying power law with consistency index k=2.0187×10(su−4) c 0.2066 e 2815/ T and flow behavior index n=0.76, where c is the wax content and T is the temperature in Kelvin. Soy lecithin in the range of 1–2% did not affect the rheological properties.
