Abstract
“Cam” brown rice (CBR), a Vietnamese cultivar containing a high level of anthocyanin
was germinated at various conditions to maximize anthocyanin. To obtain optimum
conditions, major factors such as soaking time, pH, germination time and temperature
were evaluated using Box-Behnken design to achieve the highest anthocyanin content in
germinated “Cam” brown rice (GCBR). The results revealed that 2.6 hrs of soaking at pH
3.1 and followed by 15.5 hrs of germination were optimal germination condition to
achieve maximum anthocyanin content (45.18 mg/100 g GCBR). Along with high content
of anthocyanin, the increased amounts of these nutrients relative to those in the un-GCBR
were 7 times for GABA, 17% polyphenol and 22% reducing sugars. In addition, GCBR
possessed good sensory characteristics in structure and taste.
