In this study, we have investigated the quality characteristics of Tteokgukdduk, a traditional Korean rice cake, containing different amounts of mugwort powder (0, 1, 3, 5, 7 w/w %). We observed that the moisture content in Tteokgukdduk containing mugwort powder ranged at 41.79 to 42.50% was not significant when compared with Tteokgukdduk that is devoid of mugwort powder. We also noted that the Hunter color L value decreased in proportion to the added mugwort powder. Further, the weight of Tteokgukdduk was found to be increased with increasing levels of added mugwort powder. However, the volume of Tteokgukdduk did not varied significantly at the different mugwort powder concentrations (P>0.05). We also observed that the hardness of uncooked Tteokgukdduk containing 3% mugwort powder showed the lowest value among Tteokgukdduk containing mugwort powder. However, it did not varied significantly at the different mugwort powder concentrations (P>0.05). In cooked Tteokgukdduk, however, we found that the nature and quality of springiness and gumminess increased with corresponding increase in the amount of added mugwort powder. Further, with regard to the sensory evaluation, the intensity (of both color and flavor) of Tteokgukdduk was found to be increased with proportionate increase in the amount of added mugwort powder. The results of this study suggest that the acceptability qualities such as color, flavor, taste, texture, and overall acceptability were of the highest order for Tteokgukdduk containing 3% mugwort powder.
