Rough rice of Oryza sativa L., cultivar RD-6 (a popular waxy rice
cultivar for consumption in the Northeast of Thailand) was selected
for the study and it was purchased from a local rice-milling
factory in Mahasarakham province, Thailand. The preparation of
germinated rice samples followed the methods studied and reported
by Saetung (2006). Ungerminated rice (UGR), or brown rice,
was prepared by removing the husk of the ungerminated rough
rice, using a laboratory de-husker.
