Abstract :
Determination of rheological properties is very important for designing of devices for honey transportation or processing. The paper deals with rheological properties of three kinds of honey originating from the Czech Republic. The following rheological properties were described: dependence of viscosity on a sample temperature, dependence of shear stress on shear rate. Based on the measured values, the Arrhenius mathematical model was applied and subsequently used for determination of activation energy. Tests were carried out under the temperatures ranging 0–50°C. The measured values revealed Newtonian behaviour of the tested honey samples in the whole temperature range
