Consistency coefficients (K), or consistency indices ( Goff et al., 1994 and Schmidt et al., 1993), were also obtained from the power law model ( Table 7). These values were positively correlated with the mouthcoating ( Table 6) and the apparent viscosity values (R2=0.850). The relation between K and apparent viscosity is not surprising as similar properties are being measure, but apparent viscosity is measured at a single shear rate while the K value is based on a range of shear rates. The main difference for these two measurements was seen for the LF sample, where the K value was significantly higher than that for the fat free sample and the same as the regular fat sample. This was not the case with the apparent viscosity measurements. Overall, the values tended to agree with the apparent viscosity and sensory viscosity data indicating the low fat and fat free samples are not as viscous as the regular fat and light samples.
