Takju, popularly known as makgeolli, is a
famous traditional alcoholic beverage in Korea. Beneficial
health effects of different traditional beverages have received
attention among consumers and researchers. The influence
of addition of blueberry and black rice powders to takju
was investigated. Chemical characteristics, color values,
DPPH radical scavenging activities, total phenolic contents,
and sensory characteristics were evaluated. Addition of
blueberry and black rice powders improved the antioxidant
activity and the overall taste of takju. The optimum
proportions of added blueberry and black rice powders
were 0.249% and 0.004-0.049%, respectively. Addition of
optimum amounts of blueberry and black rice powders
enhanced the overall quality of the Korean traditional rice
wine takju.
