  • Yukwa was prepared with different amounts of curry powder (0, 5, 10, 15, and 20%) based on the amount of waxy rice flour used, and its physical, sensory, and antioxidant properties were measured. In terms of the textural properties, the hardness began to increase when ${\geq}15%$ curry powder content was used; however, the crispiness was unchanged by the amount of curry powder used. The expansion degree of yukwa significantly decreased when 20% curry powder was used. The internal microstructure was measured by scanning electron microscopy (SEM), which showed a more compact and homogeneous structure as the curry powder content increased. The use of increased curry powder in yukwa decreased the acid and hydroperoxide values, and this could have resulted from the antioxidant action of curcumin in the curry powder. Through sensory evaluation, yukwa containing 15% curry powder was chosen as the most acceptable by the elderly.

  • This study investigated the quality characteristics, oxidative stability, and antioxidative activity of a Korean fried rice cake, Gaeseong-Juak (doughnut of waxy rice) to which Prunus yedoensis Matsumura (PYM) extract, vitamin C, and BHT were added and stored at $60^{\circ}C$ for 4 days. Gaeseong-Juak was prepared by adding PYM extract at 0, 0.5, 1, and 2% of waxy rice powder. It was found that as the content of PYM extract increased, L-values significantly decreased while a-value and b-value significantly increased (P<0.001). The hardness and adhesiveness were increased with an increase in PYM extract, and as the storage period increased. In the sensory evaluations, the sample containing 0.5% and 1.0% PYM extract gave good scores. In the Gaeseong-Juak with PYM extract, the acid value, peroxide value, and p-anisidin value of PYM extract groups were found to have a higher oxidative stability than those of 0% PYM extract group (P<0.05). The antioxidative activity of Gaeseong-Juak to which PYM extract was added increased as the content of PYM extract increased (P<0.001). It was suggested that the shelf life of Gaeseong-Juak could be extended by the use of natural antioxidants, reducing the deterioration of the quality of Gaeseong-Juak.

  • This study was carried out to understand and analyze the cooking and processing methods presented in CHE MIN YO SUL, Chinese books of husbandary was written in sixth century. This book was composed of two parts-part I is Agricultural production and part II is product-Utilization. Especially, wines and yeast(NU RUK) written in part II were studied at this study paper. Most of yeast was made of barley and wheat. These materials had been prepared as raw, steamed, and roasted state by proper ratio with kinds of yeast and then fermented as dough state. Occasionally, various kinds of soup made from cocklebur, leaves of mulberry tree, wormwood etc. put into yeast dough. Yeast doughs were shaped round and square with or without hole in the center, made in July of the lunar calendar and fermented for 3 or 4 weeks. There were 43 kinds of wines in this book. Most of them were made of all kinds of cereals grown at that time-rice, waxy rice, millet, waxy millet etc. These cereals had been steaming or cooking gruel with grain or powder state and then fermented with yeast. These wines were prepared by single or double brewing methods and the kinds of double brewing wines were more than single brewing wines by two times. There were none of wines made from fruit and distilled wines. Generally, single brewing wines were not made in Apr., Nov., Dec., of the lunar calendar and double brewing wines were not made in Aug., Oct., Nov., of the lunar calendar. And ripenning periods of wine brewing were various, from 1 day to 7 months for single brewing, from 2 days to 8 months for double brewing.

  • To investigate the materials in the preparation of kimchi for Koreans in the Commonwealth of Independent States(CIS) a survey was completed by 199 Koreans living in Moscow, Sahalin, Uzbekistan and Jazahstan, In the way to purvey the materials of Kimchi, the frequency to get all the materials of Kimchi in the markets is 74.7% on the whole and by regional groups the frequency is relatively high in Moscow and Kazahstan, For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moxcow and Kazahstan. For the main ingredients most respondents use Chinese cabbage, cabbage, or turnips. In general Chinese cabbage is used most, But the respondents who live in Moscow and Kazahstan. 쫴 are younger, or belong to higher emigrant generation, prefer cabbage kimchi. For the additional vegetables many respondents use carrots. For the seasonings, garlic, red pepper powder, and salt are added to Kimchi, but the use of ginger, whole seasame seed, and waxy rice paste is relatively low. The coriander, which is not added to kimchi in Korea, is used in Kimchi By above 80% of the respondents living in the three regions except Sahalin. It is considered to be due to the effect of the western dining cultural area. For the animal materials, 74.4% of the respondents add lightly salted fish to Kimchi and all toe respondents in Sahalin add salt-fermented sea food, the kind of which is mainly salt-fermented croaker. The reasons given for not adding salt-fermented seafood to Kimchi in the three regions except Sahalin, 59.9% of the respondents said it was because of the difficulty to purvey, 21.1% because of the fishy taste, and 16.8% because of not considering the addition of self-fermented sea food in Kimchi. The higher the emigrant generation of respondents, the less seasonings of strong flavor like garlic, red pepper powder, and salt-fermented sea food are used, and the more coriander is used. In the salting of Kimchi preparation, 97.8% of the respondents salt the main vegetables by soaking in brine and its concentration is controlled by experience.

  • For increasing both the viscosity and intake of calories and nutrients, four cereal powders: Goami (GR), waxy barley (WBL), germinated brown rice (GBR), and oat (OT) were added to rice porridge, and the properties of the porridge were compared with that containing a commercial thickener. Among the samples, the porridge with WBL showed the highest viscosity, whereas that with GR showed the lowest. With regards to color properties, the porridge with GR showed the highest whiteness, while those with OT or GBR had the highest yellowness, affecting the color of the rice porridge. The viscosity level of porridges with cereal powders did not reach that of the porridge with the commercial thickener at $90-95^{\circ}C$; however, at $55-60^{\circ}C$, the viscosity of the porridge with cereals was enough to replace the commercial thickener. With regards to organoleptic tests, the overall acceptability was mainly attributed to color, and there were no significant differences in other properties. From these results, it seems that the cereal powders could be suitable substitutes for commercial thickeners.

  • Recently developed black waxy rice with a giant embryo ('Nunkeunheukchal', BGE) was selected and processed to produce high quality nutritional food. BGE contains high levels of several phytochemicals with antioxidant activities, as well as other reported health beneficial properties. In addition, the giant embryo has high protein, lipid, and amino acids contents. Within the free amino acids, ${\gamma}$-aminobutyric acid (GABA), a major inhibitory neurotransmitter, has long been used for treating the aftereffects of brain injuries and stroke. A method for manufacturing pop-rice and black rice tea by popping process in BGE is provided to increase a taste, nutrition and functionality. The produced 'pop-rice' showed increased protein (11.3%) and lipid (3.7%) contents compared with control variety, IB ('Ilmibyeo'). In addition, melanoidin related products, polyphenol and functional amino acid contents were increased by the popping process. Pop-rice tea made of BGE showed the highest extraction of total sugar, glucose, raffinose and sucrose (4 times higher than brown rice) by hot water. Scavenging activity ($SC_{50}$) of processed BGE rice powder showed strong antioxidative activity of 0.24 mg/ml using DPPH and 1.82 mg/ml using ABTs method. Thereafter, these results suggested that the popping processed rice of BGE could be one of the promising materials for healthy food development.
