Germination of rice samples
Two forms of rice were prepared; (1) Rough
rice (grains with husk intact) and (2) dehulled rice
(grains with husk removed). Germination process
was conducted according to previously described
by Jiamyangyuen and Ooraikul (2008). Briefly,
rice grains (100 g) were steeped in water at room
temperature for 12 hrs and 6 hrs for rough rice and
dehulled rice, respectively. Water was drained off and
grains were washed again with water. Grains were
then left to germinate in the dark at room temperature
for 0, 6, 12, 18, and 24 hrs. After germination, the
rice grains were dried at 50°C to maintain moisture
content

The dried grains were pulverized in adomestic grinder at 30ºC to obtain ground rice flourfor further analysis.
