Liquid rheology study on refined rapeseed oil

Abstract

The rapeseed oil extracted from the mature seeds was purified by refining processing, and the rheological characteristic analysis of the viscosity and dynamic shear rate at gradient temperatures was made. The result shows that at 20, 40, 60 and 80 °C respectively, when the shear rate gradually rises, the torque increases accordingly but its viscosity does not vary distinctly. The result suggests that when rapeseed oil is used as the raw of edible oils and industries, the working procedures at high temperature will not influence its rheological characteristic distinctly.
