The fermented suspensions were used to prepare uji (pH 3.7)
and study their pasting properties using a Rapid Visco Analyser
(RVA) (Model 3 D) (Newport Scientific,Warriewood, Australia). The
RVA was programmed to rapidly stir each freshly prepared
suspension at 960 rpm for 10 s, then decrease and hold shear rate
constant at 160 rpm for the remainder of the test period. The
temperature profile involved holding initially at 50 C for 2 min,
then increasing to 91 C over 4 min and holding at 91 C for 8 min
before finally cooling to 50 C over 4 min and holding constant for
3 min. The peak viscosity (PV) and the cool paste viscosity (CPV)
were determined for each suspension from the RVA plots. Each uji
treatment was analysed three times in duplicate.
