Dependence of the flow behaviour of fluid foods on temperature can be described by the Arrhenius relationship (Saravacos 1970; Rao 1986; Steffe 1996): K = AK exp (EK / RT ) eq. 314 J/mol K), and T is absolute temperature (K). Textural and Rheological Properties of Fruit and Vegetables 23 Yield stress is the point when the shear stress-shear rate curve starts showing deviation of shear rate from zero.

8A). The torque generated due to the drag of the fluid on the cone is measured as one of the members rotates while the other remains stationary. Test quality is best when the cone angle (θ) is small, and large errors may be encountered when the gap is improperly set or not well maintained. 8 Types of viscometers. The shear stress may be determined for a cone-and-plate configuration as: 3M 2p R 3 while the shear rate is calculated as: n= g = rW W = r tan q tan q eq. 53) eq. 54) Some of the merits of the cone-and-plate method include (i) small sample size (roughly one gram), (ii) uniform shear rate and (iii) easy to load the sample and clean the instrument.
