  • The combined application of oil cake and rice bran into the soil surface was found useful for weed control in our previous pot study. The present study was undertaken to evaluate the performance of white clover (Trifolium repens L.) while incorporated in the paddy field and effects of combined fertilizer on weed control and rice yield. A plot was divided into two parts i.e. white clover incorporated and not incorporated. The nitrogen content of the incorporated white clover was $12.5gm^{-2}$. Chemical fertilizer and combined fertilizer plots were compared with non-fertilizer conditions. The mixed ratio of combined fertilizer was oil cake 1.35 and rice bran 1.0. Combined fertilizer was applied to the soil surface, and chemical fertilizer was mixed in the soil. Nitrogen application rate was $8gm^{-2}$ for any fertilizer. The weed numbers were significantly reduced in the white clover plot irrespective of application condition both at heading and harvest time. Also, weed control ability was improved by the use of combined fertilizer. In the not incorporated plot, the number of weeds was suppressed about 90% by applying combined fertilizer. The rice yield was markedly increased by the incorporation with white clover under all fertilization conditions. Contribution rates of increased rice yield by white clover and combined fertilizer were about 55% and about 25%, respectively. The rice yield was increased by the incorporation with white clover, and the number of weeds remarkably decreased as well. Also, these effects were improved due to combined application of oil cake and rice bran.

  • In this research, we added 10%, 20% and 30% of white rice powder and colored rice powder to wheat flour, then baked cakes to appraise the quality of each cake by physical and sensory evaluation The resultsare as follows: 1) The specific gravity was increased in order of rice powder-added batters and colored rice powder-added batters. No remarkable difference was found in expansion ratio of cakes except some reduction in 30% rice powder-added cake. 2) Gumminess of cake was higher in the 30% colored rice-added cake Hardness of rice-added cakes was higher than colored rice-added ones. More adding rate of rice, higher hardness of cake. No remarkable difference was found in chewiness, springiness and cohesiveness of cakes 3) In case of color, rice-added cakes showed more L value and less b value than colored rice-added ones. Colored rice-added cakes showed less L value more a value and less b value as adding rate became higher 4) According to the results of sensory evaluation, no remarkable difference was found in the size of a cell and distribution of cells. Crumb and tenderness tended to be lower in rice added cakes than in colored rice added ones. Color was prefered in 30% colored rice added cakes over rice-added cakes and less added colored rice added cakes.

  • The effect of treatments with alcohol, chitosan, or with both alcohol and chitosan for extending the shelf-life of Korean white rice cake and wet noodle was investigated by measuring quality changes such as total microbial count, pH, and sensory qualities. Total microbial counts for control, alcohol-treated, and 1% lactic acid-treated white rice cakes exceeded the initial putrefactive criterion level of $1{\times}10^{6}\;CFU/g$ at 6, 27 and 20 days of storage, respectively. However, total microbial count of the white rice cake treated with chitosan was still less than the criterion level even at 76 days of storage. In the case of wet noodle, total microbial counts of control and alcohol-treated groups exceeded the criterion level within 7 days of storage, while that of chitosan-treated group was far less than the criterion level even at the end of storage of 82 days. Chitosan treatment extended the shelf-lives of both white rice cake and wet noodle appreciably.

  • As one of study efforts to develop a food product that can satisfy the taste of modern people and increase the usage of the popular local product of walnut in the region of Chunan, the current study developed a no sugar added functional walnut-sulgi. The walnut-sulgi was manufactured by adding walnut powder into typical sulgi rice cake. While manufacturing the walnut-sulgi rice cake, the health beneficial sugar alcohol ingredient of sorbitol was added instead of commonly used sugar to specialize the walnut-sulgi as a functional rice cake. As the result of such effort, a soft and moist walnut-sulgi was produced. The color of the newly developed walnut-sulgi is white and has a pleasing taste, and its consumer acceptability was higher than the sugar added walnut-sulgi by showing much soft sweetness and textural properties. Considering the facts that sorbitol has a lower glycemic index (GI) than sugar and the content of unsaturated fatty acids that are insufficient in rice cake could be increased, the newly developed sorbitol added walnut-sulgi is thought to be an appropriate functional rice cake that can attractively appeal to obesity and diabetes concerning modern people.

  • Germinated brown rice (GBR) flour (0%, 25%, 50%, 75% and 100%) was added to brown rice (BR) and white rice (WR) flours and the densities of pound cake batters, morphology, color value, textural properties, sensory preference test, and hardness during storage were investigated, in order to develop health functional gluten-free rice pound cakes with high nutritional value. The rice was milled with the newly developed rice milling method. The entire shape and cross section of all cakes were symmetrical and desirable. The density of pound cake batter and weight of cake increased with addition of increasing GBR. Specific volume was not significantly different (2.1-2.4 mL/g). Textural properties of cakes between WR-GBR and BR-GBR showed different trends with adding GBR. On the sensory test, overall quality of rice pound cake did not significantly differ between rice flour types. Hardness of rice pound cakes and brittleness decreased with increasing addition of GBR flour. The hardness and the peak intensity at $2{\theta}=17^{\circ}$ decreased with increasing addition of GBR. The results, that addition of GBR flour improved the nutrition value and functionality of gluten free rice pound cakes and prevented staling of rice pound cakes during storage.

  • Forty eight growing bulls of two breed types(red Sahiwal and white Kilari), fed rice straw, were allocated to nine treatment groups: 1. Control straw (CS) 2. Urea upgraded straw (UUS) 3. UUS + 0.25 kg coconut cake (CC) 4. UUS + 0.75 kg CC 5. UUS + 0.25 kg rice bran (RB) 6. UUS + 1.00 kg RB 7. UUS + 0.25 kg RB + 0.25 kg CC 8. UUS + 1.00 kg RB + 0.25 kg CC 9. CS + 1.00 kg RB + 0.25 kg CC Liveweight gain was measured weekly during 15 weeks and tested in three analyses of variance. The results are: Urea upgraded straw produced a liveweight gain $180g.d^{-1}$ higher (P <0.01) than control straw. The groups supplemented with 0.25 kg coconut cake and 1.00 kg rice bran showed an increase of $100g.d^{-1}$ (p < 0.05) over the unsupplemented groups. No interaction between straw upgrading and supplementation was present (P > 0.10). Both rice bran and coconut press cake, supplemented to upgraded straw at a level of 0.25 kg, did not increase liveweight gain (P>0.05), but 1.0 kg rice bran increased gain by $90g.d^{-1}$ (P<0.05). A supplement of 0.75 kg coconut press cake to upgraded straw increased liveweight gain by $160g.d^{-1}$ compared with 0.25 kg or 0.00 kg coconut cake supplement (P<0.05). There were no significant differences between breed types (P>0.10) or interactions between breed and the other two main treatments (upgrading and supplementation). It was concluded. that both urea upgrading and supplementation of rice straw increase animal performance. The effect of urea upgrading was the same for both supplemented and unsupplemented animals. There was no indication of a nonlinear effect of supplements on growth.

  • The white-spotted chafer, Protaetia brevitarsis (Coleoptera: Scarabaeidae), is an economically important insect in Korea. Traditionally, it has been regarded as a medicine for preventing liver-related diseases and suppressing liver cancer. Recently, this beetle was enlisted as a temporal food ingredient by Korean Ministry of Food and Drug Safety. Therefore, this beetle is focused as a one of the important insects that are commercially reared and sold in Korea. As the economic importance of this beetle is growing, the suitable rearing conditions are needed for more detailed investigation. In this study, we compared three temperature conditions and two food additives, rice chaff and soybean cake, for its effects on the body weight change of third instar larvae of P. brevitarsis. Temperature is a major environmental factor that has tremendous effects on rearing insects. In additions, rice chaff and soybean cake are byproducts of other agricultural activities. Therefore, it is easy to get, and the price is comparatively low. However, they still have meaningful amount of nutrients. With four different kinds of feed and three temperature conditions on the third instar larvae of beetles, the body weight change was tracked for 14 wk. We concluded that 27.5℃ is the optimal temperature to rear the third instar larvae among three temperatures (25, 27.5, and 30℃). Among four different feeds, conventional fermented oak saw dust with rice chaff and soybean cake was the best feed for larval weight gain during 14 wk. However, feed with soybean cake at 30 ℃ was the best condition for rearing P. brevitarsis larvae when temperatures and feeds were compared at the same time.

  • The purpose of this study is to understand consumer awareness and preference regarding rice cakes by surveying the awareness, preference, and consumption behavior of college students regarding rice cakes, and to survey their perception and usage of rice cakes, thereby using the results as basic data to establish measures to develop Korea's rice cakes. To sum up the study's results, the survey included both male (54.5%) and female (45.5%) subjects. Those aged "20 to 23" accounted for the largest share (67.9%) of total respondents, and those majoring in "humanities and social studies" comprised the largest portion (47.8%). A majority of the respondents resided in "small and medium-sized cities", and most either lived at home or lived away from their families. A majority of the subjects received monthly allowances ranging from 200,000 to 300,000 won. In order of awareness, the most well-known type of rice cake was "injeolmi (rice cake made from glutinous rice and coated with bean flour)", followed by "songpyeon (half-moon-shaped rice cake)", "garaeddeok (bar rice cake)", and "baekseolgi (steamed white rice cake)". The women were better aware of "injeolmi", "baekseolgi", and "garaeddeok" than the men, and "soemeoriddeok" was not commonly known among either gender. In terms of preferences for rice cakes, overall, the subjects liked "injeolmi" and "songpyeon" the most. However, certain differences were found in preferences for rice cakes between the men and women. The women exhibited higher levels of preference for "injeolmi" and "songpyeon" than the men. On the other hand, the men revealed higher levels of preference for "baekseolgi", "jeolpyeon", and "garaeddeok" than the women. The most common answer to important factors for popularizing rice cakes was "a diverse assortment of rice cakes", followed by "the development of creative technologies" and "the taste of rice cakes reflecting consumer needs", in order of importance. Among the important factors to popularize rice cakes, "the development of unique packaging containers for rice cakes" (p<0.05) and "the development of proper packaging materials" (p<0.05) showed statistically significant differences. In the survey of consumption of rice cakes, the most frequent answer to the question "why do you like rice cakes? was "their tastes are good" with 146 respondents, followed by "I have been eating them for long" with 115 respondents. To the question "when do you use rice cakes", the most frequent answer was "I use them in daily life" with 133 respondents, followed by "I use them at special events" with 115 respondents. The women were found to use rice cakes frequently in daily life, whereas the men used them frequently at special events. When asked whether they had the intention to use rice cakes as a meal substitute, 100 men answered that they had no intention, whereas 96 women answered that they had the intention. When asked about the type of rice cake considered suitable for a meal substitute, the most popular answer was "injeolmi" with 108 respondents, followed by "baekseolgi" with 106 respondents.

  • 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.

  • Germinated brown rice (GBR) has received great attention due to its enhanced nutritional value. Brown waxy rice was germinated at $30^{\circ}C$ for 10 h, 20 h, or 30 h with 95% humidity. The color, texture, digestibility, and sensory characteristics of waxy rice cake made by GBR were evaluated. Pasting viscosity of rice flour was substantially reduced, whereas ${\gamma}$-amino butyric acid content increased with an increase in germination time. Lightness of rice cake with GBR was lower than that with brown rice, whereas the redness and yellowness of rice cake were higher after germination. For textural properties, the hardness, gumminess, and chewiness of rice cake with GBR were lower than those with brown rice, and decreased hardness was more prominent with an increase in germination time. The in vitro starch digestibility of rice cake was elevated by germination, showing an increase in rapidly digestible starch content and decrease in resistant starch content. In the sensory evaluation, the overall acceptability of rice cake with brown rice and GBR was greater than that with white rice, whereas it was reduced with an increase in germination time.
