Different G’ exhibited by waxy rice starches may be attributed to
the difference in the breakdown of the amylopectin matrix inside
the swollen starch granules (Keetels and van Vliet,1994). G0 depends
upon factors like granule rigidity and swollen granule phase volume.
Lii et al. (1996) postulated that rheological behavior of gelatinized
starch suspension could be influenced by inter-granular interactions,
such as entanglement between surface molecules of adjacent
granules and the granular properties.
