This study was carried on the analysis of nutritional value and preference between the plain gruel (Hyun Jook) and the experimental gruel (Tarak Jook, Jangkook Jook & Chajohonhab Jook) in order to improve the quality and variety of menu patterns of gruels for the patients requiring soft diet. The results obtained are as follows: 1. In comparing the calorie coutent of each gruel, Tarak Jook, Jangkook Jook, and Chajohonhab Jook had more calories-82.7%), 39.3% and 12.4% respectively-than Hyun Jook. Additionally, in the case of protein content, Tarak Jook, Jangkook Jook and Chajohonhab Jook showed higher values than Hyun Jook by 270%, 137% and 28.3% respectively. 2. The preference for each experimental gruel compared with Hyun Jook, as a function of taste, color and concentration of the gruels was shown to be insignificant. But the color and concentration did effect the preference level for each gruel. Hoverer, patients did have a preference for particular gruels: Jankook Jook, Tarak Jook, Chajohorhab Jook in descending order. 3. Overall, 65.6% of the patients requiring soft diet thought gruel was only for the sick 57.1%) thought the reason for gruel as a soft diet was that it could be digested easily 75.8% of the patients disliked gruel and their frequency of intake was very low 78.8% did not know more than 5 types of gruel. Hoverer patients did prefer a loose gluel(48.4%). In couclusion, awareness of gruel as a soft diet for patients and its intake as one not to meution as a normal diet was low.

Four kinds of Bupleuri Radix, namely 'Dang shiho', 'Won shiho', 'Shik shiho' and 'Jook shiho', are currently used in the market of Korea. It is thought that 'Dang shiho' is the root of Bupleurum falcatum and B. scorzoneraefolium. It was also reported that 'Won shiho' and 'Shik shiho' are the root of B. falcatum. Since 'Jook shiho' which is widely used in the market and even exported, has not been clarified as to the origin of the plant and the chemical components, the author obtained some results by this study, the summaries of which are as following: 1. The results of microscopical examination of 'Jook shiho' and 'Kae shiho' were entirely identical and the TLC patterns were coincided as well. It was therefore definitely clarified that the origin of 'Jook shiho' is Bupleurum longe-radiatum. 2. The TLC patterns of 'Won shiho', 'Jook shiho' and 'Kae shiho' which are belonging to the same family and the same genus, appeared identical, and reveal the similarity of the chemical constituents and thereby strongly support the fact that 'Jook shiho' can be used for the same purpose as 'Won shiho'.

This study examined the effects of added amounts of lotus leaf powder on the physical and sensory properties of Jook. As the level of lotus leaf powder in samples increased, L-values and a-values decreased and b-values increased. In addition, the Jook had higher viscosity and lower spreadability values as the amount of lotus leaf powder increased. Sensory characteristics such as color intensity, viscosity, astringency, and nutty taste increased significantly with the addition of lotus leaf powder. And the results of the consumer acceptability test showed that the Jook containing $2%{\sim}3%$ lotus leaf powder had the highest score. In conclusion, to enhance the quality of Jook, a 2% addition of lotus leaf powder would be the most beneficial.

In this study, the alteration of Jook was studied by analyzing and comparing ingredients of Jook appeared in the reference of cookbooks from 1611 to 1958. 121 kinds of Jooks were mentioned 371 times. The Jooks made only with grains, mostly Hin Jook (white Gruel) made of rice, were recorded 31 times in 10 kinds. Rice or processed rice appeared most (194 times) as main ingredients in Jooks other than Hin Jook. As for condiments, honey and sugar were mentioned 37 times, accounting for one third of the condiments recorded as used for Jooks. The basic ingredient of Jooks were rice, but mostly the Jooks were named after the subsidiary materials. Chinese medicinal ingredients were most among the subsidiary materials; 35 kinds of them were mentioned 73 times. As regards the ingredients of the Jook, the other ingredients were added to the grain ingredients between the 17th century and the 19th century whereas only grains were put into Jook during the 20th century.
