Injeolmi is a kind of rice cake made from glutionusrice grains by steaming and pounding much into dough. The way of making Injeolmis has an important effect on the characteristics of Injeolmis; whether the glutinous rice is Japonica or Japonica/Indica, and whether it is steamed in rice grain, or in rice powder. The characteristics of Injeolmi were investigated through sensory evaluation and Instron Universal testing machine. The results were as follows; 1. Injeolmi which was steamed in glutinous rice was more chewier than powder Injeolmi after 48 hours. 2. In the case of changing ${\beta}$-starch to ${\alpha}$-starch by reheating. Injeolmi with microwave oven, the result was same as above investigation in color, appearance, and chewiness. But in hardness grain Injeolmi became tenderer. 3. Instron measurement of texture indicated that there were significant differences in hardness. This result was the same as that by the sensory evaluation. 4. The preference for Injeolmi was increased when it was made of high moisture contented glutinous rice. japonica had more moisture than J/Indica.

This study attempts to analyze the physicochemical characteristics of rice flour developed as rice powder for exclusive use, steamed rice cake recipes developed as basic recipefor rice cakes. The study also aims to compare the quality characteristics of steamed rice cakes in an effort to establish the possibilities of developing various rice cake recipes. The moisture content and amylose content increased as the rice powder particles for exclusive use became finer. With regards to water uptake, in the case of the Hungara type, the water uptake increased as rice powder particles increased in size. In the case of the Shingil and commercial types, the water uptake decreased as rice powder particles increased in size, and solubility and swelling force decreased as rice powder particles increased in size. In the case of chromaticity, Sulgidduk made with rice powder for exclusive use the brightness (L value) increased as powder particles became finer and the yellow indexes (b value) decreased, and this was especially pronounced in the Shingil type. The measurements of changes in the mechanical textures of Sulgidduk showed that rice types with larger particles led to lower hardness, cohesiveness, springiness, and chewiness.

Effect of various ingredients and cooling methods on the quality of modified Jeung-pyun(traditional Korean steamed rice cake) were studied. Three different kinds of wheat flours(strong, medium, and weak) were studied to evaluate the volume and firmness of Jeung-pyun. Weak flour showed the maximum volume and good sensory results. The optimum ratio of ingredients was flour : water ; sugar ; Tak-Ju=100 : 20 : 20 : 50 for steaned Jeung-pyun. When three different cooking methods were compared, the maximum volume showed from convection oven method, but the crust color of Jeung-pyun was like bread. Steaming method showed higher volume than that of product heated by microwave method. The optimum formula ratio for the microwave method was flour ; water ; sugar ; Tak-Ju = 100 : 30 : 20 : 50, which required 10% higher added water content than that of steaming. When wheat flour was used instead of rice flour, the addition of 5% normal corn starch increased volume of both steamed and microwave cooked products. In the case of added modified starches to Jeung-pyn, 5% $\alpha$-waxy corn starch showed the highest volume in steaming method. When rice flour was used, the addition of 5%$\alpha$-waxy corn starch also showed highest volume f both steamed and microwave cooked products. The firmness of steamed wheat flour Jeung-pyun, containing 5%$\alpha$-corn starch was higher firmness than that of control and other added samples. Microwave cooked products showed two or three times higher firmness of steaming products. The use of wrap(uni-wrap) and stabilizer(METHOCEL) decreased the firmness of microwave cooked wheat flour Jeung-pyun to 200~300g compared with that of untreated Jeung-pyun.

This study was performed to increase the utilization of rice and improve the productivity of jochung, traditional food in Korea. Two kinds of jochung products were prepared from steamed rice(SR) and wet-milled rice flour(WRF) by rice cultivated from 2006 to 2010. It is common to add a liquefying enzyme for rice liquefaction(4 $m{\ell}$/1,000 g rice, at $90{\sim}95^{\circ}C$, 3 h) and saccharogenic enzyme with malt(45 g/1,000 g rice, at $55{\sim}57^{\circ}C$, 6 h). In order to evaluate the quality characteristics of jochung, producing rate, pH, solidity, reducing sugar, dextrose equivalence(D.E.), viscosity, total phenolic compound, color value and sensory evaluation were carried out. In terms of the producing rate of jochung, WRF jochung was produced about 7.4% much more than SR jochung. There was no difference in producing rate between the jochung cultivated from 2006 to 2010 rice. The pH varied from 4.86~5.66, solidity was 79.48~82.28%. Color L value was 25.82~27.92, a value of 1.28~2.81, b value were 2.98~4.33. The results of sensory evaluation for jochung, as a whole, received higher score than for the commercial product(Daesang Co., Ltd, Seoul, Korea), overall acceptability score was the highest in the 2008SR. Reducing sugar, dextrose equivalence(D.E.) and total phenolic compounds were determined to be higher WRF jochung than SR jochung, while viscosity was lower WRF jochung than SR jochung. These results are thought to be due to increased surface area of rice by milling. SR jochung manufacturd by wet-milled rice flour will increase the producing rate for jochung, thereby saving manufacturing time and costs.

This study was undertaken to investigate the effect of cereals on the physicochemical and sensory characteristics of Noti. Noti is one of Korean traditional pan-fried glutinous cereal cakes. Noti made from the steamed glutinous rice flour, glutinous Chinese millet flour, glutinous millet flour or glutinous Indian millet flour is saccharified with malt, and then pan-fried. Noti also has sweet taste without sugar added. In addition, Noti has elastic characteristic, high calorie and good flavor. Long storage makes it better taste. In this case, Noti was made from the steamed glutinous rice flour. By the sensory evaluation, color, flavor and moistness were unfavorable according to the storage. Consistency was not strongly increased when comparing with the common rice cake depending upon the storage. The texture tended to increase by storage period. Optimum conditions of the safe storage and overall acceptability were to add 15% malt and keep 6hr saccharification time at 60$^{\circ}C$. During the period of storage for 90 days, reducing sugar content was similar, moisture content was low and maintained, and the acid value was not increased abruptly. The hardness was not increased rapidly and fungal growth was considerably low. Cohesiveness and elasticity were increased during storage.

Surimi products are among the most prominent seafoods in Korea. Together with fish meat, wheat flour is a major ingredient in the preparation of surimi products. Rice flour, however, can be an effective ingredient in enhancing the rheological characteristics of surimi products. In this study, we evaluated the potential of rice flour as an agent to replace wheat flour in surimi products. The effects of rice flour milling types and addition methods on the rheological and sensory properties of surimi products were investigated. Among different addition methods, the surimi product containing non-treated rice flour showed better gel strength and sensory properties than products containing paste (1:1.3 rice flour/water, w/v) and steamed paste (steamed at $100^{\circ}C$ for 30 min). According to the gel strength results for surimi products with added roll-mill (40 mesh) and jet-mill (180 mesh) rice flours, the roll-mill rice flour shows good potential as a replacement for wheat flour. When considering gel strength and sensory properties, an effective amount of rice flour to add was 10-15% (w/w). In conclusion, the rheological and sensory properties of surimi products containing rice flour were comparable with those of a premium commercial surimi product. Therefore, rice flour might be an effective alternative to wheat flour for premium surimi products.

This study was performed to investigate the food preference trends of the children according to age increase and change of the times. The subjects were 1,450 children who are fifth grade of primary school and 2,000 juveniles who are senior high school in 1993. This survey data were compared with the Food preference study of the primary school aged children in 1987.' The results of this study can be summarized as follows 1. State of the general taste The subject had a high preferences to bulgogi(roast beef), panbroiled cuttlefish, steamed egg, fried sausage and donuts among the all sorts of 165 principal and subsidiary foods. But, fried beef liver, pancake, sweet potato with syrup, spinach soup and boiled rice with red bean didn't suit for their taste. Compared with survey data done in 1987, in present study significantly increased preferences to steamed food, pan frying and parboiled vegetables were shown. Particularly, food preference was changed with the cooking methods rather than materials. 2. Differences of the preference according to change of the times In present study, except the rice cakes preferences to all sorts of foods were improved and markedly increased preferences to steamed food, parboiled vegetables and mixed with seasonings were observed. Compared with 87's study deviation of the preference to cooking materials was decreased considerably. Preferences to salty tasted foods as like as stew and salted food were low no better than before. 3. Changes of preference according to age increase Among the principal foods, increased preferences to boiled rice and cereals were shown but to one-dish meal, bread and rice cake were decreased. Among the subsidiary foods, significantly decreased preference to frying was observed. Irrespectively of the cooking methods, preferences to fish and vegetables were improved. And in the frying and panbroiled foods, deviation of preferences to cooking materials were considerable, which means the fixation of food behavior.
