Flow properties of soft cheese type Fromage frais

Flow properties of soft cheese type Fromage frais were obtained using standard coaxial cylinder system and resulting from measurements torque on the shaft of the rotating 4-blade vane immersed in the fluid tested. The rheological characterisation was performed as a function of temperature varied from 10 to 65oC. The 'static' yield stress of the material tested was also determined by so-called 'vane method'. The shear stress - shear rate data were approximated using power-law, Casson and Herschel-Bulkley models. Further discussion was performed with respect to temperature effect on the rheological parameters by matching the Arrhenius type equations.
