Rheological measurements for all samples involved a shear rate sweep of 10 readings between 18.61 and 232.2 s−1. Apparent viscosity, consistency coefficients and flow behaviour indices were determined using the Bohlin VOR software version 2.5. Apparent viscosity values, obtained at a shear rate of 29.3 s−1, were compared as this was as close to the shear rate within the oral cavity, while eating fatty foods similar to ice cream, as could be obtained in this study. Dickie and Kokini (1983), have estimated oral cavity shear rates on fatty dairy foods similar to ice cream to be 11.5 s−1 or less. Shear rate readings at 18.6 and 23.3 s−1 could not used for apparent viscosity comparisons because the desired linear relationship between shear rate and shear stress was not established due to background noise. The 18.8 gcm rheometer torque element was used for all measurements.
