This study examined the physiochemical and organoleptic properties of the yanggaeng fabricated with different contents of ginger powder. The moisture contents ranged between 39.85% and 47.92%. The yanggaeng made with 0.5 g of ginger powder showed the lowest moisture content of 37.04%, whereas the yanggaeng made with 1.5 g of ginger powder showed the highest moisture content of 47.92%. As for the L value, which indicates lightuess, the yanggaeng made with 1.5 g of ginger powder showed a L value of 13.92, whereas the yanggaeng made with 0.5 g showed the lowest L value of 12.35, (p<0.05). The values for redness (a value) ranged between 4.69 and 5.58, and there was no significant difference as the content of ginger powder increased. The value for yellowness, (b value) ranged between 3.19 and 2.33, and showed a significant decreasing trend as the ginger powder content increased (p<0.05). The sugar concentrations were 53.82~46.56, and decreased as the ginger content increased. The pH ranged between 6.42~6.52, and showed significant differences. As the ginger content increased, changes in hardness, adhesiveness, gumminess, and chewiness, were all significant (p<0.05). Characteristics of cohesiveness and springiness, showed no significant differences. Although there were no significant differences in color, flavor, chewiness, and hardness, there was a decreasing flavor preference as the content of ginger powder increased. There were significant differences in sweetness, moistness, and overall-preference (p<0.05). For overall-preference, the yanggaeng with 1.0 g of added ginger powder showed a high preference level. The study results implied that ginger powder may be used in fabricating yanggaeng. and a 0.5% content of added ginger powder will improve the preference level.

대잎 분말 첨가 설기떡의 관능적 특성과 기계적 특성, 수분 함량과 색도를 측정하였다. 대잎분말의 첨가량은 0%인 대조군을 BP0으로 하였으며, 1% 첨가군을 BP1, 2% 첨가군을 BP2, 3% 첨가군을 BP3, 4% 첨가군을 BP4로 표기하였다. Textureanalyzer 분석 결과를 살펴보면 설기떡에 대잎 분말 첨가량을 증가하면 할수록 견고도가 증가하고, 부착성과 점착성, 씹힘성, 응집성도 첨가량이 증가함에 따라 증가되는 결과가 나타났다. 그러나 탄력성은 다른 처리구와 다르게 유의적으로 차이가 없었다. 수분 함량은 대잎 첨가 설기떡의 경우 37~39%를 유지하였으며, 색도는 대잎 분말의 첨가 수준이 증가될수록 L값은 감소되며 a, b값은 증가 되는 경향이었다. 관능평가 결과는 색과 촉촉한 정도에서 BF3가 가장 높게 평가되었다. 이러한 연구 결과로 BF3의 첨가구가 가장 바람직한 첨가 비율임을 알 수 있었다. 따라서 맛과 기능적인 면에 대한 것도 기대를 걸어보며, 앞으로 후속 연구가 더 많이 나오기를 기대한다.

This study investigated the quality characteristics of baked rice cake using dry and wet rice flour. The moisture contents, color values, texture and sensory evaluation(attribute difference and acceptance) for the samples were tested. The moisture content of baked rice cake was the highest in rice cake baked with non- glutinous rice of dry type, and rice cake baked in dry type had weaker brownishness and therefore had higher brightness value compared to the rice cake baked in wet type. In relation to the texture, the hardness was found to be the highest in the rice cake baked with wet non- glutinous rice, and the rice cake baked with glutinous rice was found to be soft. The hardness was the lowest in both wet and dry glutinous rice, and was the highest in the wet non- glutinous rice. Attribute difference test of samples showed that, the rice cake baked with glutinous rice showed clear manifestation of springiness, moistness, adhesiveness, and gumminess (except for the harness). Although the cake baked with dry rice powder showed no significant difference, the dry glutinous rice flour was preferred the most. The rice cake baked with wet glutinous rice flour was preferred the most in terms of flavor, taste, texture, and overall acceptability.

Sulgidduk is a steamed 'Dduk' that is made from rice flour mixed with various ingredients. It is steamed in an earthenware steamer according to a particular procedure. Soyflour Sulgidduk was prepared with two types of soyflour(yellow, and black). This study was carried out to improve the quality of Sulgidduk. The quality was affected by not only the ratio of the ingredients, but also by the amount of soyflour. The results of these experiments can be summarized as follows. As the amount of soyflours(yellow and black) increased 10 %, 20 %,30 %, and 40 % into the control recipe, it was found that the overall rheological properties, such as hardness, gumminess, brittleness, cohesiveness, and springiness, of Sulgidduk decreased. The L-value of the color decreased as more soyflour was added into Sulgidduk but the b-value increased. When the same amount of black soyflour was added to Sulgiddut addition of black soyflour produced lower lightness than yellow soyflour addition. Yellow soyflour addition into Sulgidduk yielded a higher a-value, closer to red. As the results of sensory evaluation, following to the added amount of soyflour, the sensory degree of flavor, moistness, and chewiness of Sulgidduk decreased. The addition of 20 g soyflour resulted in the best overall quality based on sensory evaluations. Therefore the optimum recipe of Soyflour Sulgidduk was obtained as follows; 20 g(20%) soyflour, 80 g rice, and 20 mL water.
