This study investigated and monitored the rheological
properties of different flour combinations, with
and without salt in batter systems. It was found that
the rheological properties varied with the different
types of flours and their combination ratios. The addition
of corn flour greatly influenced viscosity and viscoelastic
properties of wheat based and rice based
batter systems as viscosity decreased with an increase
the corn flour proportion in the batter system. Both
corn and rice reduced the viscosity and increased the
onset temperature (Tonset), storage module (G0
max Peak
value) and loss module (G00
max peak value) of wheat
flour based batter systems. Salt significantly influenced
the flow properties of batter systems by lowering the
viscosity and decreasing G0
max and G00
max as well as
increasing the onset temperature. A higher temperature
and longer time was required to gelatinize starch at
higher proportions of rice flour (70%) for each flour
mix combination in the batter systems tested in this
study.
