2.7. Determination of apparent cold water viscosity of the starches
The RVA (RVA, StarchMaster 2, Perten, Australia) was used to
determine apparent cold water viscosity of the samples at 25 C.
The suspension was first mixed manually using the RVA plastic
paddle for 1 min and then the canister was placed inside the
instrument and stirred using the paddle at 960 rpm for the first
20 s and then at 160 rpm for the rest of the experiment. The apparent
viscosity of the samples after 15 min stirring at a constant temperature
(25 C) was reported.
