The instrumental apparent viscosity measurements for the RF sample gave a value of 87.2 mPa at 30°C at a shear rate of 29.3 s−1. This value is significantly lower than the L sample but higher than the ice cream samples of lower fat levels. Interestingly, the values for the L sample is similar to that obtained by Goff et al. (1994) of 130 mPa at 20 s−1 and 30°C for a regular fat formulation. The lower apparent viscosities seen for the LF and FF samples (Table 7) were similar to those detected by the trained panelists and there was a correlation between sensory and instrumentally determined apparent viscosity (Table 6). Apparent viscosity was also correlated with the mouthcoating.
