  • Glutinous rice dduk, traditional Korean rice cake, was prepared using rice(white glutinous rice, brown glutinous rice, black glutinous rice, gaba glutinous rice) as a meal alternative, and each of their quality characteristics were compared. This study had checked sensory tests, color differences, moisture contents, texture characteristics, and storage lives of dduk during storage at room temperature for 6 days. The moisture contents of black glutinous rice dduk scored the highest. For color properties, gaba glutinous rice dduk was darker with a decreased yellow value, whereas its red value was higher comparing with that of brown glutinous rice dduk. The results of the preference test showed that appearance, flavor, texture, and overall preference were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the lowest score. The results of the color difference test showed that softness, viscoelasticity, and fineness were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the highest difference in color. For individual textural characteristics, black glutinous rice dduk showed the highest score, whereas white glutinous rice dduk showed the lowest scores in hardness, chewiness, and gumminess. In the results of the textural characteristics of dduk during storage, white glutinous rice dduk showed the highest increase in hardness after 48 hours, whereas black glutinous rice dduk showed the lowest increase. White glutinous rice dduk showed the highest increases in chewiness and gumminess. Cohesiveness decreased in all glutinous rice dduk. In the results of fungal occurrence in dduk during storage, black and gaba glutinous rice dduk showed increased fungi occurrence compared with white and brown glutinous rice dduk after 6 days. In conclusion, the overall preference for glutinous rice dduk made from different rice is more affected by appearance or texture than flavor.

  • Objectives : To examine various ways non-glutinous rice has been applied in different formulas of "Shanghanlun" and the relationship between non-glutinous rice and the formulas' effects. Methods : First, texts that included non-glutinous rice were selected from the "Shanghanlun". Then, they were categorized according to the application of non-glutinous rice, followed by analysis of its relationship with each formula. Results : Most formulas that used non-glutinous rice in raw form when decocting with other ingredients included Shigao. Non-glutinous rice alleviates coldness of Shigao as in the case with Taohuatang where it stops diarrhea. Non-glutinous rice used in Wumeiwan warms the center and boosts Qi and helps the medicinal ingredients to bind when made into pellets. In Guizhitang and Lizhongwan, non-glutinous rice assists Stomach Qi. In Shizaotang, porridge is taken after diarrhea to help quick recovery. To prevent damage of Zheng Qi, Baisan can be mixed with rice water for administration. The level of cathartic effect can be managed through giving cold or hot porridge to the patient according to his/her response to the medicine. Mazirenwan, Mulizexiesan, Banxiasan, Sinisan, Wulingsan are mixed in rice water for administration. It makes it easier to swallow than when mixed with plain water. The application of rice flour is either internal or external. In Zhufutang, where rice flour is parched, it harmonizes the center and stops diarrhea. In Daqinglongtang when there is too much perspiration, warm powder is sprinkled on the skin to stop sweating. Clear porridge in Jiuziyisifang and rice flour in Shechuangzisan were exclusive to "Jinguiyaolue", while Baisan and rice water mixture could only be found in "Shanghanlun". Conclusions : The excavation and research on various ways non-glutinous rice was applied in treatment holds certain meaning in contemporary practice of Korean Medicine where treatment leans heavily on medicinal treatment rather than food, and all ingredients are boiled together in large quantities for most decoctions.

  • To optimize the preparation process for oven-roasted glutinous rice cake, an experiment was derived using a central mixing composite design to determine the optimal conditions. The addition of flour by soaking time as well as sucrose and water, were the independent variables, with the moisture content, color, sensory, and texture properties of the ovenroasted glutinous rice cakes selected as response variables. For the moisture content, color, sensory, and textural properties, we found significant effects for moisture, lightness, redness, hardness, and cohesiveness in the oven-roasted glutinous rice cakes, and water was one of the most influential factors. The optimal mixing conditions for the highest quality oven-roasted glutinous rice cake, in terms of sensory and textural properties, were 266.0 g of water, 25.4 g of sucrose, and 61.5 minutes of soaking time for the glutinous rice flour. The soaking time was in close to the median, whereas the water and sucrose values were slightly above the median.

  • The purpose of this study was to investigate the quality characteristics of Kugija-Injeulmi by varying the ingredient ratio of Lycii fructus powder (4, 6 and 8%). According to sensory evaluation of Kugija-Injeulmi, as the ratio of Lycii fructus powder was increased, the bitterness, hardness and chewiness all increased. It was found that Kugija-Injeulmi made of glutinous rice was moistened and softened with the addition of more Lycii fructus powder, but it was rougher than Kugija-Injeulmi made of glutinous rice flour. As a result of textural analysis of Kugija-Injeulmi, the hardness, adhesiveness, gumminess and chewiness increased as the amount of Lycii fructus powder increased, whereas the cohesiveness decreased. Kugija-Injeulmi made of glutinous rice was moister than Kugija-Injeulmi made of glutinous rice flour. The overall-acceptability was negatively correlated with coarseness. The overall-acceptability of Kugija-Injeulmi made of glutinous rice was much higher than that made of glutinous rice flour. From the above results, the most advisable mixture ratio of Kugija-Injeulmi is as follows Kugija-Injeulmi add 282g (94%) glutinous rice flour, Lycii fructus powder 18g (6%) and salt 3g. The moisture content was 42.22%.

  • This study was carried out to compare the cooking and antioxidant characteristics of cooked rice added at various rate of glutinous rice addition and treated with two cooking methods. Cooked rice added with glutinous rice was cooked by general and high pressure cooking method with and without fermented alcohol. Pasting characteristics of cooked rice were decreased as increasing the amounts of glutinous rice. Water binding capacity and swelling power were significant decreased with the amounts of glutinous rice increasing, however water solubility indices were significant increased. Palatability characteristics of cooked rice added with glutinous rice showed similar results to cooked rice without glutinous rice. Total polyphenol contents of cooked rice added with glutinous rice and fermented alcohol were significantly distinct, but there was no significant difference. Total flavonoid contents were increased as increasing the amounts of glutinous rice. Total flavonoid contents by general cooking method of cooked rice added with 20% glutinous rice and fermented alcohol were $23.20{\pm}0.61{\mu}g\;CE/g$. DPPH radical scavenging activities added with and without glutinous rice were 2.97~5.19 and 3.19~5.45 mg TE/100 g, respectively. ABTS radical scavenging activities by high pressure cooking method of cooked rice added with 20% glutinous rice and fermented alcohol were $19.48{\pm}0.63mg\;TE/100g$. In this study, cooking and antioxidant characteristics of cooked rice added with glutinous rice were expected to be used as basic data on manufacturing processed products.
