where h is the viscosity of the solution and h0 is the viscosity of the
solvent. t and t0 are the times required for the sample and solvent
(DMSO 90%) to pass through the U-tube and r and r0 are solution
and solvent densities, respectively. The native corn starch was also
tested without being subjected to pasting after being sieved using a
sieve with the mesh size of 120
