This study was aimed to find an optimum amount of jujube paste to ice flour for the preparation of Daechupyun(jujube rice cake). The moisture content of Daechupyun added with jujube paste was 40∼42%. The more jujube paste was added, the L-value and b-value were decreased, and a-value of Daechupyun was increased. In the mechanical evaluation of Dachupyun, the hardness was the lowest in the samples with 12% jujube paste after 12-hour storage. The adhesiveness and springiness were not significantly different by adding jujube paste after 24-hour storage. The cohesiveness was increased with the increase of added jujube paste at 12, 36 and 48 hours of storage. The gumminess was the lowest in the samples with 12% jujube paste during storage. In the sensory evaluation of Daechupyun, the acceptance for the softness and chewiness war the best in the samples with 12% jujube paste. Daechupyun with 12-16% of jujube paste to rice flour was found to be the best recipe based on the sensory qualities of softness, chewiness and overall acceptability.

This study investigates the effects of cooking utensils and jujube(Zizyphus jujuba Mill. cv. Dongzao) paste on the quality characteristics of yakbab. Yakbab samples prepared with jujube paste were divided into a control(yakbab with 0% of jujube paste) and the groups with jujube paste added. The samples prepared with jujube paste were divided into JY1(yakbab with 2.60% of jujube paste), JY2(yakbab with 4.27% of jujube paste), JY3(yakbab with 5.88% of jujube paste), JY4(yakbab with 7.43% of jujube paste) and JY5(yakbab with 8.94% of jujube paste). The moisture content and the color score of pressure cooker treatment have higher than those of the pot. The moisture contents of JY2 and JY5 samples increased as compared to the other samples. The L(lightness) value scores of all samples with jujube paste added were higher than those of the others. Hardness, springiness and cohesiveness of JY4 sample showed higher than those of the control. Higher scores for color, moistness, mouth feel, sweet taste and overall taste were found in JY4 products as compared to the other samples.

Jujube paste was prepared by autoclaving the fresh jujube at 1.2 atm and $120^{\circ}C$ for 30 min and removing the skin and cores. In order to increase the juice yield, the paste was treated with pectinase, cellulase and their combinations. The soluble fractions of enzymatically treated jujube paste were characterized in terms of yield, pH, titratable acidity, color, Bx, transmittance and sugar compositions. The original paste exhibited the water soluble fraction of 57.3%. Of various quality factors, the clarity was the most significantly distinguished between pectinase and cellulase treatments. The cellulase treatment produced the cloudy juice with the yield of 83.60%. On the other hand, the clear juice was produced by the pectinase and combined treatments due to degradation of pectins, whose yields were 79.47% and 85.39%, respectively. The results clearly demonstrated that the pectinase treatments improved the solubilization efficiency and clarity.

This study was performed to investigate the quality characteristics of Yakpyun with added brown rice. The Yakpyun was prepared with polished rice, brown rice, Jujube paste, Makkolli, sugar and salt. The Yakpyun was made with various levels (0, 20, 40, 60 or 80%) of added brown rice. After making the Yakpyun, it was examined for the effect of adding brown rice on quality characteristics using scanning electron microscopy (SEM), a mechanical test, and a sensory evaluation. The moisture contents of Yakpyun tended to decrease with increasing amounts of added brown rice, but no significant differences were observed. As the content of brown rice increased, the lightness (L) decreased and redness (a) and yellowness (b) increased. In a texture profile analysis, hardness decreased with increasing brown rice content from the moment of production to 3 days of storage. When more brown rice was added, rough surfaces were found more often under SEM, and large holes were evident between granules. The results of the sensory evaluation showed that overall acceptability was the highest for Yakpyun containing 40% added brown rice.

This experiment was conducted to investigate processing method and usage of dried yam, "Sanyak". Jujube showed the higher value in extract, brix and extract content compared with Danggui and Sanyak. Mixing of Sanyak with Jujube and Danggui was proper to raise extract and taste. Brix and extract content was $1.17^{\circ}$ and 1.80% higher, respectively, in 12 hours of extraction than in 8 hours of extraction. The apt mixing ratio was 3 : 4 : 3 (Sanyak : Danggui : Jujube). By adding 70% of glucose and 10% of lactose to 20% of extract, good viscosity and appearance of paste were obtained. 1.5mm of granule thickness was proper in phase of manufacturing, drying and shaping.

This study was aimed at research on Jeonyak (煎藥) appearing in the bibliography. It was during the Goryeo Dynasty that Jeonyak was first mentioned in literature. At this time, Jeonyak was served for consumption during Palgwanhoe. The ingredients and recipes of Jeonyak were listed for the first time in Suunjapbang, a book written by Kim Yu during the Joseon Dynasty. Since then, they have been found in various books and materials. During the Joseon Dynasty, Jeonyak was made in Neuiwon, a medical administrative organization in the palace, and administered as a seasonal food on Dongji Day in the winter. The king gave various to his guests or subjects as special gifts. As a result, Jeonyak became well known to many people and even to those in foreign countries. Jeonyak is a Korean traditional medicated diet food made from decocted beef-feet, bone stock, and other spices, including jujube paste, honey, ginger, pepper, clove, and cinnamon. Jeonyak has a long 800-year history, and its ingredients and recipes have changed only gradually. Milk was a major ingredient of Jeonyak during the Goryeo Dynasty, but glue and gelatin were added in the Joseon Dynasty. Since then, recipes have mainly used gelatin made from beef-feet, skin, beef-bone, and so on. In conclusion, Jeonyak has an 800-year history as a special medicated diet food (藥膳) served seasonally on Dongji Day in the winter.

This study was carried out to investigate correlation with food preference of subjects in three constitution groups on the view point of constitutional medicine. The constitutions of 124 college students(male 80, female 44) was classified by QSCC II method. Food preference of the subjects was surveyed in accordance with suggested foods for each constitution and was analyzed using Hedonic scale. The distribution of the constitutional revealed that Soeum individuals accounts 53%, followed by ; Soyang 19%, Taeum 28%. For men, sorghum, potatoes, beef, scombroid, oyster, saury, octopus, codfish, walleye pollack, shrimp, croaker, pineapple, eggplant, leek, pumpkin, toenjang, draft beer, diluted liquor, coffee, cocoa were statistically different in food preference score by sasang constitution(p<0.05). For woman, chicken, pollack roe, a walleye pollack, persimmon, jujube, melon, citron, celery, burdock, vinegar, bean-paste soup, draft beer, ginseng, honey were statistically different in food preference score by sasang constitution(p<0.05). Association of sasang constitutions and food thought to be harmful or healthy to each constitution was analyzed. But Food preference score of food thought to be harmful or healthy were not statistically different in score among sasang constitutions. This results suggested that food intake patterns of subjects were associated with sasang constitutional food in parts.
