The objective of this study was to evaluate the quality characteristics of Cheongpomook prepared with five different levels of mungbean powder (0, 25, 50, 75, and 100%). We conducted the Hunter's color values, the rheological characteristics, sensory evaluations, and pasting properties of the Cheongpomook samples. The more mungbean powder was added, the more the luminance and Hunter's a values of Cheongpomook samples were decreased, but in Hunter's a values was reverse. With regard to the rheological properties of the Cheongpomook samples, the more mungbean powder was added, the values of hardness, springiness, gumminess, and chewiness were significantly decreased. In color, taste, and overall quality, the value of 25% mungbean powder added Cheongpomook (MP1) and 50% added Cheongpomook (MP2) were significantly higher than those of others. The resulting RVA viscogram, peak viscosity, hold viscosity, break down, setback, and final viscosity of Cheongpomook were decreased with an increase in mungbean powder, but the pasting temperature was increased slightly. Therefore, an addition of 25% mungbean powder appears to be an acceptable approach to enhance the quality of Cheongpomook without reducing acceptability.

The quality characteristics and antioxidant activities of Cheongpomook prepared with different amounts of aronia (Aronia melanocarpa) powder were studied. Freeze-dried aronia powder was incorporated into mung bean starch at different levels (1, 3 and 5% aronia powder based on the total weight of mung bean starch). Moisture content in control group was 89.7% and was not significantly different from the different levels of aronia powder groups. Syneresis, hardness, chewiness and gumminess were increased with higher amounts of aronia powder in Cheongpomook. In chromaticity determination, the L value of the samples decreased but the a and b values increased with increasing the levels of aronia powder in Cheongpomook. The total polyphenols, flavonoids and anthocyanin contents were proportionally increased with increasing the levels of aronia powder added in Cheongpomook. The antioxidant activity measured by DPPH and ABTS radical scavenging activities was significantly higher than control and increased proportionally to the aronia powder concentration. The sensory evaluation indicated that the 5% aronia powder showed the best preference in color, taste, flavor, hardness, and overall acceptance. These results suggest that aronia powder may be useful ingredient in Cheongpomook to improve quality and antioxidant potential.
