초록

The quality characteristics, total phenolic content, anthocyanin content, and DPPH radical scavenging activity of rice nutritional bar with added powder of aronia byproducts were investigated in this study. The rice nutritional bar was prepared by adding aronia byproducts powder at concentrations of 0%, 2%, 4%, and 6%. The pH of the rice nutritional bar batter was lowered for the control and 2% aronia byproducts powder was added. The moisture content, baking loss rate, leavening rate and specific volume of the rice nutritional bar decreased with as the aronia byproducts powder content increased. In relation to measurements of the colors of the rice nutritional bar crust and crumbs, as the content of aronia byproducts powder increased, the L and b values decreased while the a value increased. From texture analysis, the hardness and chewiness increased according to the level of added aronia byproducts powder, but the springiness and cohesiveness decreased. The total phenolic content, anthocyanin content, and DPPH radical scavenging activity showed the highest values in the rice bar with 6% aronia byproducts powder added. According to a sensory evaluation, overall preference was highest for the rice bar with 4% added aronia byproducts powder, whereas the color and taste was rated higher for the rice bar added with 4% and 6% aronia byproducts powder.
