This study investigated the quality characteristics of burdock glutinous rice dasik prepared with different contents of freezedried burdock powder (0, 3, 6, 9 and 12%) and roasted glutinous rice. The moisture contents of burdock glutinous rice dasik significantly increased as the amount of burdock powder increased(p<0.001). The L-value, a-value and b-value of burdock glutinous rice dasik were lower than those of the control group. The sugar content of glutinous rice dasik added with 6% or more burdock powder was higher than that of the control group. The hardness and adhesiveness significantly increased as the amount of burdock powder increased. The DPPH free radical scavenging activities of burdock glutinous rice dasik added with 9% and 12% burdock powder was higher than that of the control group. In the sensory evaluation, the burdock glutinous rice dasik added with 6% burdock powder was highly preferred, and was thus as the optimal mixing ratio for texture and sensory characteristics.

Dasik is a kind of traditional Korean dessert, which has polysaccharides as the major base. Dasik was prepared using rice and various ingredients and its antioxidant properties were determined. In addition, textural changes and sensory evaluation were conducted on Dasik during 7-day storage at $4^{\circ}C$. Dasik containing brown rice, red ginseng, and rice bran oil showed higher radical scavenging ability, reducing power, total flavonoid, and total phenolic contents among tested rice-based samples. Dasik prepared using black sesame seeds showed the highest radical scavenging ability and reducing power compared to rice-based Dasik. In sensory evaluation, 10 trained panelists found that hardness of the rice-based Omija Dasik sample increased significantly (P<0.05) while moistness and softness attributes decreased as the storage period of Dasik increased. The roasted bean Dasik and black sesame Dasik samples were evaluated similarly and their moistness decreased significantly (P<0.05) with longer storage period. The overall and texture acceptability of the rice-based Omija Dasik and the roasted bean Dasik samples decreased significantly (P<0.05), and scores of willingness to try again of the rice-based Omija Dasik decreased as the storage period of Dasik increased. Positive or negative correlations among the results from sensory evaluation and textural analysis were observed in Dasik.

The purpose of this study was to determine the most appropriate ratio for burdock glutinous rice Dasik. Burdock glutinous rice Dasik was prepared with different levels of burdock powder (0, 3, 6, 9 and 12%) and the quality characteristics of burdock glutinous rice Dasik were analyzed. Moisture contents of burdock glutinous rice Dasik increased as the amount of burdock powder increased (p<0.001) compared to the control group. The L-value, a-value, and b-value of burdock glutinous rice Dasik showed a tendency to decrease compared to the control group. The sugar content of burdock glutinous rice Dasik increased (p<0.001) with the amount of burdock powder. The hardness and adhesiveness of the glutinous rice Dasik with burdock powder of 6% or less were decreased, but those with 9% or more burdock powder had higher hardness and adhesiveness than the control group. In addition, the cohesiveness, springiness, gumminess, and chewiness of glutinous rice Dasik with burdock powder increased compared to the control group. The DPPH free radical scavenging activity of the glutinous rice Dasik with 9% and 12% burdock powder were higher than that of the control group (p<0.001). In the sensory test of burdock glutinous rice Dasik, the samples added with 3% and 6% burdock powder gained higher preferences, but the evaluations of others were lower than that of the control group. The glutinous rice Dasik with less than 6% burdock powder was highly evaluated, so it is considered as the most appropriate sample.

This study attempts to find optimum mixing proportion of rice dasik with yam powder by adding rice powder in different quantity and using honey and oligosaccharide as a sweetener. The results of the mechanical test and the sensory test on rice dasik are as follows. Moisture content of honey added one had less moisture than oligosaccharide added one did while having more sugar content than that. In color, honey added one showed the higher L-value and a-value than those of oligosaccharide added one, but it had the lower b-value. In hardness, chewiness, gumminess, and cohesiveness, oligosaccharide added one was higher. As a result of the preference test, the group which was added with 20% of yam powder was the highest. Based on the results above, adding yam powder makes the preference of rice dasik high, and the one added with 20% of yam powder is the best for rice dasik when using honey and oligosaccharide. This study used honey and oligosaccharide as a sweetening ingredient to make rice dasik, but it is necessary to research dasik with various sweetners and their different ratios.

Quality characteristics of dasik were studied with varied the levels of rice grain particle size and green tea powder and compared them with commercially sold dasik. Among the samples with the same number of grinding times, the sample groups with the higher amount of green tea showed significantly the less mosture content(p<0.05). Hardness was higher in the samples containing higher amount of green tea among the ones with the same grain size (p<0.05). The M13G0.5 was evaluated to have the highest savory aroma with significance (p<0.05), and C1 to have the highest sweetness by sensory analysis. The developed dasik samples with lower rice grain particle size had significantly lower adhesiveness, chewiness, gumminess, and cohesiveness compared to those of commercial sample groups. In sensory tests, the compared groups showed significantly the higher savory aroma and flavor and very lower hardness when compared to those of commercial sample groups. With the results above, dasik with with varied the levels of rice grain particle size and green tea powder were developed with improved qualities compared to those of commercially sold dasik.

This study was carried out to investigate the possibility of improving the texture and the flavor of Dasik made of the Omija extract, various sugars and rice powder. Sensory quality and mechanical characteristics of Dasik were compared. The moisture content of the Croup of tile Dasik added with Omija extract was higher than that with non-Omija extract The Omija Dasik containing molasses showed the highest value (23.5%) in moisture content. In sensory quality, Omija Dasik containing honey and symp showed the highest score in overall acceptability (6.2 and 6.0, respectively). The Rice Dasik containing syrup showed the highest values in lightness (L) and yellowness (b) in color. The Omija Dasik containing syrup showed the highest values in redness (a) in color. The Dasik added with honey and syrup were lower in hardness, but higher in cohesiveness, springiness, gumminess and brittleness of textural characteristics. When sensory quality and mechanical characteristics of the Dasik were compared with, the gumminess and brittleness in mechanical characteristics were positively correlated with the appearance and the taste acceptability in sensory quality (p<.01, p<.05). The springiness was negatively correlated with the tooth packing in sensory quality (p<.001). The Omija Dasik was more desirable in flavor, taste and overall acceptability, especially those added with honey and syrup. From the above results, the honey might be replaced by the less expensive syrup, when making the Omija Dasik.

This study was conducted to identify the sensory characteristics of the Korean traditional confectionery, dasik, prepared under different conditions and to compare their consumer acceptance in Korea. To accomplish this, descriptive analysis of eight samples prepared using two types of rice cake powder, dasik (Rflour, Rflour_Omija), brown rice powder red ginseng dasik (Brice_Ginseng_P), pinepollen dasik (PineP), black sesame dasik (BSesame), bean dasik (Rbean), and two types of mungbean starch dasik (Starch_Omija, Starch_Greentea), was conducted by ten trained panelists. In addition, 81 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale, as well as the perceived intensities of sesame flavor, sweetness, and hardness using a 9-point just-about-right (JAR) scale. Partial least square- regression (PLSR) indicated that the BSesame and Rbean samples, which had significantly (p<0.05) high roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor scores, had the highest acceptability and consumer desire scores. Additionally, the PineP and Rflour_Omija samples, which had relatively high particle size, transparency, roughness, spoiled tofu, fermentation and raw rice flavor scores, were the least preferred samples. Therefore, roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor attributes were considered drivers of "liking" whereas particle size, transparent, roughness, spoiled tofu, fermentation, and raw rice flavor attributes acted as drivers of "disliking" among consumers.
