There were no significant differences in the pasting properties of
rice stored with or without exhausters and here the main influence
was probably that of storage time. Sowbhagya and Bhattacharaya
(2001) reported that the structure of rice can become more organized
during storage, creating a barrier at the starch surface that
prevents hydration. This phenomenon can increase the pasting
temperature of rice. Zhou et al. (2003) reported the same behavior
for these parameters in native rice starch that was stored for 12
months and suggested that this effect could be due to the interaction
between starch and other compounds. The breakdown also
decreased as a function of the storage period for the grains that
were stored in both the silos equipped or not equipped with exhausters,
Noomhorn et al. (1997) stated that a decreased breakdown
indicates that the rupture capacity of the starch granules
after cooking was significantly reduced by aging.
