떡과 한과는 수백 년 전부터 우리 식생활 전반에 걸쳐서 밀접한 관계를 가지고 있다. 슬플 때나, 기쁠 때나, 정을 나눌 때나 언제나 떡과 한과는 우리와 함께 해 왔다. 건강에 대한 관심이 고조되면서 세계의 많은 사람들이 한국음식에 관심을 갖기 시작하였다. 이에 따라 우리의 떡과 한과에 대한 관심도 높아져 신세대와 외국인 등 우리 떡에 대한 새로운 변화를 기대하는 사람들이 매우 급증하는 추세이다. 서양의 피자, 케이크, 빵류가 우리의 생활에 침투하였듯이 우리의 떡과 한과도 좀 더 연구 개발에 힘쓴다면, 서양의 문화에 자연스럽게 침투하여 세계인의 생활 속에 친숙한 음식문화도 자리 잡을 수 있을 것이다.

The objectives of this study were to investigate quality characteristics of Ssookgaedduck which containing 0, 5, 10, 15, 20% of mugwort. The result of sensory evaluation showed that the Ssookgaedduck containing 10-15% mugwort had the high overall acceptability, color and flavor preference. By increasing the level of mugwort, Hunter color L value of Ssookgaedduck decreased. The hardness of Ssookgaedduck increased by the addition of mugwort. However, during 3 days of storage, the hardness of 10-20% mugwort containing Ssookgaedduk increased slowly. For 3 days of storage, 20% mugwort containing Ssookgaedduk showed the lowest total bacterial count than others.

Rice cake is the most historical food which has been developed from settlement of agriculture and typical traditional food which has manufacture and food historical meaning. Because, the process of rice flour, raw ingredient of rice cake, tells remarkable food processing technology of our nation, and is original form of processed food that we has been taken before agricultural life begun. In this study, contents analysis method is used. Ingredients of rice cakes appeared in "Gyuhapchongseo" glutinous rice 12 times (42.8%), nonglutinous rice 10 times (35.7%), and the others 6 times (21.4%) used as the main ingredients of rice cake. the rice cake separated into 15 types (53.5%) of steamed rice cake, 2 types (7.1%) of pounded rice cake, 3 types (10.7%) of boiled rice cake, 7 types (25%) of sauteed rice cake, and 1 types (3.5%) of the others. it become data for knowing social and dietary culture of the time. And it is for presenting fundamental material of possibility of modern rice cake.

The purpose of this study was to investigate the quality characteristics of Garaedduk with regard to the amount of added whole soybean curd (Chun-Tofu). Whole soybean curd was added in amounts of 0, 3, 6 and 9%. Whole soybean curd Topokki dduk was stored at room temperature for 48 hours. The moisture contents had no significant difference for increases in the amount of whole soybean curd. The L value and b values of Garaedduk increased significantly with increases in the amount of whole soybean curd. Texture characteristics of Garaedduk measured with a texture analyzer revealed that hardness and cohesiveness decreased significantly for different amounts of whole soybean curd, and hardness increased significantly and cohesiveness and chewiness decreased with increase of storage time. As for sensory characteristics, samples with 9% added whole soybean curd rated higher in overall acceptability compared with other samples. In regard to cooking properties, water absorption increased and solid contents decreased with increases in the amount of whole soybean curd. Therefore, Garaedduk containing 9% whole soybean curd was most preferable.

We investigated the quality of Topokkidduk created by an increasing number of extrusions (1,2, and 3 passes) using an extruder. The moisture content significantly increased with an increasing number of extrusions. The moisture content of Topokkidduk was highest at 50.8% (p<0.05) after 3 extrusions. A texture analyzer revealed that the hardness and chewiness of Topokkidduk was reduced and the cohesiveness was increased after more extrusions. Also, water absorption was reduced and solid content was increased after more extrusions. A sensory evaluation revealed that Topokkidduk after 2 extrusions (6.42 score) seemed better than other samples. Therefore, the moisture content, texture and sensory evaluation of Topokkidduk were most suitable after 2 pass extrusions.

This study was conducted to investigate supression functions of retrogradation in Korean rice cake by various surfactants. Samples were manufactured by multifunctional extruder and wrapped with polyethylene wrap at 2$0^{\circ}C$ for four days of storage. In the thermal characteristics studies on supression of retrogradation, the Korean rice cake with various surfactants had lower onset temperature compared to the control. The Korean rice cake with GLF (glycerin fatty acid ester) had the lowest onset temperature. In case of peak temperatures, they showed a similar tendency to the onset temperature. All the Korean rice cakes added with various surfactants had low melting enthalpy values compared to the control. In addition the Korean rice cake with GLF added had the lowest melting enthalpy. Melting spreadabilities of the Korean rice cake added with GLF, SUF, SOF and PST were higher values than that of the control. The n value of Avrami exponent was 0.90 in case of the Korean rice cake added with GLF and its retrogradation was slowly progressed compared to the other samples. The Korean rice cake with GLF had the lowest rate constants of retrogradation. The recrystallinity of the Korean rice cake with GLF was relatively lower than that of the control. The rate constant of retrogradation showed the lowest value in case of GLF. All the Korean rice cakes added with surfactants were in good compared to the control in sensory characteristics. GLF exhibited the best effect in sensory characteristics during storage. In conclusion surfactant showed suppression effect of retrogradation in Korean rice cake, and GLF was best effective.

In order to increase the use of rice, ginseng Garaedduks and Topokki were made and the physicochemical and sensory properties were investigated. Topokki and Garaedduks were added with 0, 1, 3 and 5% ginseng powder and stored at $20^{\circ}C$ for 48 hours. The moisture contents were not different to the increasing amount of ginseng powder and increasing storage time for 48 hours. The moisture content of Garaedduks for control and 5% added ginseng powder were 48.08% and 49.62%, respectively. The L value in color of uncooked ginseng Garaedduk decreased according to the added amount of ginseng powder, and the b value in color increased significantly according to the added amount of ginseng powder and during 48 hours storage at $20^{\circ}C$. Textural analysis, measured using a texture analyzer, of Garaedduk revealed that hardness, cohesiveness, chewiness decreased significantly and adhesiveness increased according to the added amount of ginseng powder. In sensory evaluation, 5% ginseng Garaedduk (uncooked, cooked) scored higher in overall acceptability than those of the other samples. In cooking properties, water absorption and solid contents increased according to the added amount of ginseng powder. Therefore, Garaedduk containing 5% ginseng powder was the most preferable. These results implied that the degree of retrogradation of ginseng Garaedduk might be low due to its high dietary fiber content.

Textural changes of glutinous rice cakes during storage at $4^{\circ}C$ were evaluated by ${\beta}$-amylase digestibility and hardness. Some physical properties of starch including X-ray diffraction, swelling power, water holding capacity and gelatinization temperature were investigated. Changes in hardness were inversely related to the enzyme digestibility. The initial hardness for Tongil glutinous rice cake is much higher than that for Traditional one. Both parameters were changed rapidly during one and two days of storage for Tongil and Traditional glutinous rice cakes, respectively. These results implied that the differences in the strach structure might have significant influences on the texture of rice cakes. Sensory evalution revealed that hardness of the rice cakes was highly significant to the storage time and rice variety.
