Due to gelatinisation during the heating/cooking process, starch
is irreversibly swollen in the parboiled rice. It is also thermally broken down to low molecular weight products depending on the
time/temperature combination during processing (Mahanta and
Bhattacharya, 1989). The different methods of parboiling, which
differ in time/temperature combinations, will have significantly
different extent of starch breakdown. The effect of starch breakdown on the cooking and eating quality of parboiled rice has not
been reported in detail.
