This study was intended to investigate the optimal soaking time of glutinous rice for making jujube Injeolmi, a kind of traditional Korean glutinous rice cake. The jujube Injeolmi was prepared with glutinous rice soaked for various times (2, 4, 6, 8, 10 hr), and the moisture content, chromaticity, sensory qualities and mechanical qualities were measured while storing them up to 72 hr at 20$^{\circ}C$. The moisture content and L-value of jujube Injeolmi were the highest at 8-hr soaking. The a-value was the highest at 6-hr soaking. The hardness was maintained the lowest at the 8-hr soaked sample during storage. The cohesiveness and springiness were not significantly affected by the soaking time. The gumminess was significantly different among the samples during storage. The results of sensory evaluation showed that jujube Injeolmi had the best color at 4-hr soaking and the highest sweetness at 6-hr soaking. The 8-hr soaked glutinous rice gave the highest level of softness, chewiness and moistness in the sample, therefore, 8-hr soaking appeared to be the most desirable method for making jujube Ingeolmi.

Baekhaju is commonly called Bangmoonju. However comparing Baekhaju while Baekhaju used distiller's grains, Bangmoonju did not use them. Baekhaju used only nonglutinous rice, however, Bangmoonju used glutinous rice or a mixture of glutinous rice and nonglutinous rice. Baekhaju in Chinese, which was misrecored on Baekhaju in Korean from 15th century. However, Baekhaju should be distingnish from Baekhwaju, which is made buy addition of many flowers in various wine. Baekhaju used distiller's grains in the first step of its manufacture procedure. For the fermentation of Baekhaju, one of the three bases, which are rice gruel, rice cake or 구멍떡 was added to distiller's grains. Flours and nuruk are also added. In the second step, steamed water-soaked rice and nuruk was added up to the Baekhaju-base which was got from the first step.

This paper has examined and analyzed the ways of making Jang(Korean soybean sauce), vinegar and liquor in terms of food processes, which are mentioned in sooljip 5 and 6 Food collections of 'Kosa-sibi Jip', an encyclopaedia written in Chinese and published in 1789-the eleventh year of King Jung-jo of Chosun Dynasty. There respestively six items of nine items of and thirty three items of the recipe for making jang, vinegar and liquor, Soybean was a major material for making jang. And wheat flour and ground barley were added. Myun-jang was made from only flour. Dong-kook Jojang Bup(oriental soybean sauce preparation) which is the traditional Korean process for making jang from only soybean is recorded in this book. The cereals used in the nine items of the vinegar making recipe were rice(six times), wheat(twice), barley(three times) and wheat flour(once). And fruits are also used. Rice was most used of all these materials. The cereals used in the thirty three items of the liquor-making recipe were regular rice(50%), sticky rice(42.6%) and wheat flour(7.4%) In particular sticky rice was much used for Yakyee Rhue and Bok-sik Rhue for medications. The ways of processing cereals for liquor-making were Jee-ae-bop : steamed rice(52.9%), Jook:thick gruel with cereal (32.3%), Goo-mung Tuck: doughnut-shaped rice cake(8.8%) and Hin-moo-ree Tuck: shawith peless rice cake(2.9%). The three unique processes are as follows. First, in winter when the process of liquor-making did not go on because the jar was cold, the bottle with hot water in was put in the jar and so the aduquate temperature for liquor-making was maintained. Next, in warming up a small double boiler, they prevented effervescence by hanging down thread. Finally. in warming up in a double boiler, they sealed the mouth-piece of the jar and put a handful of wet rice when the rice was completely cooked, it was thought of as the sign that the process of liquor-making was done.

Yackwa is a Korean traditional fried cake made by went flour, sesame oil and honey. This study was investigated to the Rice-Yackwa for the purpose of the improvement of Yackwa's quality and rice consumption by sensory evaluation and instrumental measurement. It was resulted that taste and flavor of Rice-Yackwas were better than those of Wheat-Yackwa by sensory evaluation. We tested whether the mesh of the rice (80,100,120) and swelling agents (baking power, soju : Korean alcholic beverage) affected the Rice-Yackwa's swelling or not. In result, not by soju but by baking powder Rice-Yackwas were swelled. But Rice-Yackwa was so hard, that the Yackwas were made by the two different compositions of mixed flour (rice : wheat ; 75:25, 50:50) exibited softer than those made by rice. The hardness of 25 g% mixed flour Yackwa was improved. And we examined the softening effect on rice and mixed flour Yackwa by the increasing storage periods (1, 2, 3, 5 days). Rice-Yackwa's hardness was changed more greatly than Wheat-Yackwa's by storage periods. In addition to we inspected the effluence of sesame oil in the pross of frying. Sesame oil (40%) was drown out the Rice-Yackwa.

This study investigated retrogradation properties of Jeungpyun substituted for cereals with dietary fibers of 60% of brown rice, and barley. Quality changes during storage periods of the functional Jeungpyun, were studied using $\alpha$-amylase iodine enzyme digestion methods, X-ray diffraction patterns, and differential scanning calorimetry (DSC). The barley substituted samples showed significantly lower retrogrdation rates than those of control when examined by $\alpha$-amylase method. The Relative crystallity by X-ray diffraction patterns had typical A type in all samples with appealing big crystallity around its diffraction angle 23$^{\circ}$degrees as storage periods were increased. The brown rice and barley Jeunpyun made smaller crystallity than that of control, representing slower retrogradation rates. The batter controls had significantly lower ΔH than the other compared samples when measured by DSC, but had significantly higher ΔH after 30 days of storage, implying that the control required more energy for regelatinization after the 30 days of storage.

In this study, Seolgi Tteok was made in order to increase consumption of Geuk, which possesses numerous nutritional advantages, and its optimum content as a new food coloring for rice cake was determined. Quality characteristics and quantitative description analysis (QDA) of Seolgi Tteok, in which Geuk was added at 0, 4, 8, and 12%, was conducted. Consumer acceptability test was also conducted. As the amount of added Geuk increased, moisture content of Seolgi Tteok increased as well. Brightness (L-value) was the highest in the control group, and more Geuk resulted in higher values of red index (a-value) and yellow index (b-value), which corresponded to the results of the sensory evaluation. As result of the mechanical texture measurement, only adhesiveness and resilience show a significant difference. As a result of the QDA, 17 sensory characteristic terms were assessed. Among them, only 13 showed a significant difference. Among the different sensory characteristics, almost all of them except for taste characteristics were significantly influenced by the amount of Geuk. The aroma and taste of Geuk were not largely influenced. It can be suggested that Geuk is not a factor that strongly influences flavor. In conclusion, Geuk does not have a strong influence on the taste or aroma of Seolgi Tteok but does on color characteristics. It can be suggested that Geuk is qualified as a coloring material for food, and the reasonable addition amount is 8%. As a result of this research, Geuk can be considered as a coloring material for other types of rice cake, traditional Korean sweets, and even confectioneries as well as for Seolgi Tteok. This implies that Geuk can be utilized to develop various new products as a coloring material with abundant nutritional content, which will contribute to the promotion of Geuk consumption.

Changes were evaluated in chemical and textural properties of Jeung-pyun (fermented rice cake) altered by the particle size of rice flour, amount of added Tak-ju (Korean traditional unrefined liquor) and sucrose, fermentation time and temperature, and steaming time. Particle size of polished rice flour did not affect the volume expansion during fermentation of rice dough by Tak-ju. The maximum expanded volume was noted in the dough, containing 20% sucrose (rice flour vs sucrose = 5 : 1, w/w), fermented at $35^{\circ}C$ for 3 hours. Any volume expansion was not occurred in rice dough without sucrose. The highest value of reducing power and gelatinization degree were observed in the rice dough with Tak-ju (rice flour vs Tak-ju = 2 : 1, w/v), while the lowest blue value was revealed in that case. Steaming followed after fermentation made the smaller volume of bulk by $45{\sim}50%$ of the initial volume be showed just after fermentation. Jeung-pyun prepared under the conditions could give maximum expanded volume by fermentation showed the best overall quality by sensory and textual properties.
