This study investigated the optimal mix ratio of frozen-dried loquat fruit powder and the optimun conditions for making Seolgidduk by analyzing chemical properties, rating moisture contents, color, mechanical quality characteristics and sensory characteristics Seolgidduk was made with 0, 2, 4, 6 and 8% frozen-dried loquat fruit powder, which contains functional components. Chemical analysis showed that loquat fruit powder contained of 12.87% water, 2.23% crude protein, 0.55% crude fat, 3.57% crude ash and 3.89% crude fiber. Water content of Seolgidduk containing loquat fruit ranged from 36.58~39.18%. With more loquat fruit powder L value decreased, while the 'a' value and 'b' values increased. According to scanning electronic microscopy, Seolgidduk containing frozen-dried loquat fruit powder showed weak coherence. Hardness decreased with more frozen-dried loquat fruit powder. In the sensory test, Seolgidduk with 4% loquat fruit powder was the most preferred with less sourness, proper softness, moisture and chewiness. Based on the results of this experiment, Seolgidduk with 4% loquat fruit powder showed less hardness than the control group. These results show that quality and preference increased when 4% loquat fruit powder was added to Seolgidduk. Therefore, Seolgidduk with 4% of loquat fruit powder is expected to increase quality and preference of Seolgidduk.

The purpose of this study was to investigate quality characteristics of Seolgidduk containing 0, 3, 5, 7 and 9％ Poria cocos Wolf powder during the storage at 2$0^{\circ}C$ by measuring water content, color value, texture and sensory characteristics. By increasing the amount of Poria cocos Wolf powder, water content of Seolgidduk did not show any significant difference during storage. Hunter color L value of Seolgidduk decreased, and a and b value increased significantly by increasing the amount of Poria cocos Wolf powder. The cohesiveness of Seolgidduk decreased but adhesiveness, gumminess and chewiness were not significantly different by increasing the amount of Poria cocos Wolf powder. 3％ Poria cocos Wolf added Seolgidduk was the highest in color, odor, taste, softness, moistness and overall preference from the sensory evaluation. Above results indicated that 3％ Poria cocos Wolf added Seolgidduk showed the best quality through sensory and texture analysis.

This study tried to investigate the best mixing ratio by reviewing the quality characteristics such as moisture content, chromaticity and texture, and sensory characteristics of Seolgidduk made of different ratios of persimmon extracts. A and b color values appeared to increase and L value (lightness) to decrease according to the increase of persimmon extracts ratio. In the case of texture, hardness, adhesiveness, springiness, cohesiveness, gumminess and chewiness increased according to the increase of added amount of dried persimmon extracts. The inside section of Seolgidduk was investigated through scanning electron microphotograph, and the $15\%$ of dried persimmon extracts had the smallest and uniform air cells. Seolgidduk with $15\%$ persimmon extracts showed the highest color, flavor and chewiness scores of 3.85, 3.65, and 3.80 from sensory evaluation, respectively. The moistness displayed significant differences according to the increment of the extract Seolgidduk with $15\%$ persimmon extracts displayed the highest overall acceptability of 3.95, while that of the control 3.10. From the above results, $15\%$ mixing ratio of dried persimmons extracts seems to be the most desirable for making Seolgidduk.

본 연구는 안토시아닌 색소를 비롯한 여러 가지 생리활성 성분을 지니고 있는 오디 설기떡의 품질특성을 관찰하기 위해 수행되었다. 오디 설기떡의 최적 농도 조건 선정을 위해 수 차례 예비 실험한 결과 오디 4％ 첨가군이 가장 좋게 평가되었으나, 오디 특유의 새콤한 맛과 향 및 암회색의 색상을 나타내었다. 그러므로 오디 설기떡의 기호도를 높이고자 식품의 맛과 향 유지에 탁월한 효과를 내는 구연산 함량을 달리하여 특성을 관찰한 결과 구연산의 첨가량이 증가할수록 pH가 감소하였으며(p<0.01), 산도는 증가되었다(p<0.001). 수분함량은 실험군간에 유의적인 차이는 나타나지 않았다. 색도는 L값의 경우 대조군과 구연산 첨가군간의 유의적인 차이는 없었으나, 구연산 첨가량이 증가할수록 감소하는 경향이었다 적색도를 나타내는 a값 및 황색도를 나타내는 b값은 구연산 함량이 증가함에 따라 유의적으로 증가되었다(p<0.001). 견고성은 구연산 첨가군이 대조군보다 유의적으로 낮았으며(p<0.001), 응집성과 탄력성은 대조군과 0.1％ 구연산 첨가군간의 유의적인 차이가 없었다. 씹힘성과 깨짐성은 대조군이 각각 제일 크게 나타났다. 관능검사 실험결과 떡의 색상에 대한 기호도는 구연산의 첨가비율이 많아질수록 기호도 도 증가되었다. 맛, 씹힘성 및 전반적인 기호도에 대한 평가는 구연산 0.01％ 첨가구가 가장 높았다(p<0.001). 이와 같은 실험 결과로 안토시아닌을 비롯한 여러 가지 특수성분을 지니고 있는 오디 설기떡의 맛과 향 유지에 탁월한 효과를 내는 구연산을 첨가함으로써 떡의 대중화에 이바지 할 수 있으리라 사료된다.

Various Korean healthy foods containing Deoduk were developed and standardized recipe. Sensory evaluations of Koreans and foreigners for these developed foods were performed by using the 5-point hedonic scale. The results of the sensory test on foods containing Deoduk were as follows: Deoduk bap (2.90~3.91), Deoduk seolgidduk (3.19~4.40), Deoduk gangjeong (3.00~4.60), riasted Deoduk with red pepper paste (2.73~4.20), Deoduk pine nut juice salad (2.40~3.96), and Seopsansam (3.91~3.81). Deoduk seolgidduk, developed by using a recipe for Sansambyeong which in a Chosun dynasty cook-book, was highly preferred by Africans, Japanese, and Koreans. In particular, all foreigners except Southeast Asians liked Deoduk gangjeong, and both Koreans and foreigners liked Seopsansam. Foreigners' experience of eating foods containing Deoduk was high at 'No' (68.9%), whereas Japanese (60.0%) had previous experience. Exactly 91.6% of Koreans responded 'Yes' to the question of whether or not Deoduk food is good for health, whereas the proportion of foreign respondents who said 'Yes' was 43.2%, 'No' was 5.4%, and 'I don't know' was 51.4%. Deoduk seolgidduk was preferred by Japanese, and most foreigners preferred Deoduk gangjeong and Seopsansam. Therefore, Deoduk could be developed as a healthy food for globalization of Korean food. However, as foreigners' awareness of Deoduk is low, we must positively promote the health function of traditional food ingredients and develop various menus suitable forforeigners' tastes for the globalization of Korean food.
