The results showed that apparent viscosity decreased
with increasing shear rate for all samples. As the shear
rate increased, the particle–particle interaction was deformed
and eventually disrupted which resulted in the
size reduction of the flocs and resulted in decreasing of
viscosity. At higher shear rate, the viscosity reached a
constant value because all of flocs and large particles
were completely disrupted. Therefore, only individual
and small particles remained in the system (McClements,
1999). n Values obtained from the experiments
were in the range of 0.713–0.930 indicating that homogenized
coconut milk behaved like a pseudoplastic fluid
which were consistent with those have been reported
by Vitali et al. (1985) and Simuang et al. (2004). For
all coconut milk samples, an increase in fat concentration
was accompanied with an increase in pseudoplasticity,
shown by a decrease in values of the flow behavior
index. At similar level of heat treatment, an increase in
consistency coefficient (K) was observed with increasing
fat content indicating an increase in apparent viscosity.
The reason was that the presence of large number of
particles increased resistance to the flow which hence resulted
in an increase in the apparent viscosity
