  • This study surveyed consumers' sensory liking ratings of 3 types of developed brown rice products (brown rice nut waffles, Kimchi and tuna rice ball, sweet red-bean paste rice ball) and analyzed the drivers for liking or disliking the brown rice products. Each brown rice product had a brown rice to brown rice powder ratio of either: 100:0; 80:20; or 50:50. Forty consumers evaluated the acceptance of brown rice products on a 9-point hedonic scale and gave comments regarding liking or disliking each product. The results of the preference investigation analysis showed subjectivity depending on the brown rice product and the respondents' genders and ages. For brown rice nut waffles was affected by gender, age, and brown rice powder mixing ratio (p < 0.05). The variables "liking the aroma"; "liking the delicate flavor"; "liking the chewiness"; "liking the moistness"; "liking the softness"; "liking the harmony"; "liking the aftertaste" and "overall acceptability" did not differ significantly with the Kimchi and tuna rice ball. For the sweet red-bean paste rice ball product, the rates of liking the chewiness, stickiness, moistness, and softness of the 0% brown rice powder mix were all higher (p < 0.05) than were the rates of liking those same qualities in the 50% brown rice powder mix. Among all brown rice products, there were high correlations between the overall acceptability, liking the saltiness, liking the aroma, and liking the harmony. A preference investigation analysis showed that the brown rice product fillings were key factors to the products' overall acceptability.

  • N fertilizer required by rice could be reduced greatly in the rice-barley double cropping system than in the rice single cropping system. This study was conducted to investigate how much of the N fertilizer during the early stage of rice in the rice-barley double cropping system, could be saved compared to that in the rice single cropping system. This experiment was carried out at the paddy field of the National Crop Experiment Station in Suwon, Korea during three years from 1999 to 2001. Amounts of soil mineral nitrogen (SMN) and SPAD values of rice leaf during rice growing season in the rice-barley double cropping system were higher than those in the rice single cropping system under the same amount of N application during two years. Yield and N uptakes of rice at harvesting time were also higher in the rice-barley double cropping system than in the rice single cropping system during two years. Yield and N uptake of rice in the rice single cropping system were decreased when basal N fertilizer was omitted, but those reductions were not found by either omitting basal N fertilizer or omitting N fertilizer at tillering stage in the rice-barley double cropping system during 2000 and 2001. But yield and N uptakes of rice were decreased by 70 kg/10a and 2kgN/10a by the omission of both N application at basal and tillering stages in the rice-barley double cropping system in 2002. It was concluded that N fertilizer as much as tillering N fertilizer could be saved in the rice-barley double cropping system.

  • Purpose: The aim of this study was to compare the cooking properties of Bodeurami and Ilmi to promote consumption of rice. Methods: The properties of Bodeurami and Ilmi such as proximate composition, Hunter's color value, water absorption rate, and cooking properties as well as Hunter's color value, texture properties, and sensory evaluation of cooked rice were analyzed. Results: Crude protein, crude fat, and crude ash contents of Bodeurami and Ilmi were higher in brown rice than in white rice. Regardless of rice cultivars, L-value was lower, whereas a and b-values were higher in brown rice than in white rice. The water absorption rate of rice grains was higher in white rice than in brown rice and increased rapidly to 75 min for white rice and 4 hr for brown rice. Cooking properties, water absorption, and expansibility of white rice were higher than those of brown rice, and there were significant differences between Bodeurami and Ilmi. Immediately after cooking and after storage at warm ($70^{\circ}C$) and room temperatures ($25^{\circ}C$), hardness of cooked rice increased after storage, but was not significantly different between Bodeurami white rice and Ilmi brown rice. The sensory evaluation shows that Bodeurami brown rice scored the highest for taste, texture and overall preference. Conclusion: Thus, the results of this study shows that Bodeurami brown rice is characterized by high cooking quality without any mixed white rice, and Bodeurami white rice could be used for the rice processing industry as well as cooked rice.

  • This study investigated the quality characteristics of baked rice cake using dry and wet rice flour. The moisture contents, color values, texture and sensory evaluation(attribute difference and acceptance) for the samples were tested. The moisture content of baked rice cake was the highest in rice cake baked with non- glutinous rice of dry type, and rice cake baked in dry type had weaker brownishness and therefore had higher brightness value compared to the rice cake baked in wet type. In relation to the texture, the hardness was found to be the highest in the rice cake baked with wet non- glutinous rice, and the rice cake baked with glutinous rice was found to be soft. The hardness was the lowest in both wet and dry glutinous rice, and was the highest in the wet non- glutinous rice. Attribute difference test of samples showed that, the rice cake baked with glutinous rice showed clear manifestation of springiness, moistness, adhesiveness, and gumminess (except for the harness). Although the cake baked with dry rice powder showed no significant difference, the dry glutinous rice flour was preferred the most. The rice cake baked with wet glutinous rice flour was preferred the most in terms of flavor, taste, texture, and overall acceptability.

  • Rice Processing Complex(RPC) have being constructed with a rice mill plant and a facility of drying and storage to overcome problems caused by UR and to produce good quality of rice. An optimal design of a rice mill plant was required to successfully construct and operate it. The development of a simulation model was essential to the design of a rice mill plant. So, all the objectives of this study were to develop a simulation model for the design of a rice mill plant and to develop and evaluate the rice mill system. In this study the simulation model was developed to design a rice mill plant using SLAMSYSTEM, one of simulation languages. The results of this study were as followings. 1. A simulation model was developed with SLAMSYSTEM to represent the processes of a rice mill plant. The simulation model was used to design a rice mill pilot plant with the capacity of 0.5 ton per hour. The rice mill pilot plant was analyzed by the model with alternatives. 2. In the simulation the rice mill system was much influenced by the separating efficiency of a brown rice separator. Especially, the bottleneck of grain flow occurred at the buffer tank for brown rica. separator under 50% separating efficiency of brown rice separator. Hence, as the alternative simulation was conducted under 60% , 70% separating efficiency of brown rice separator, the bottleneck of the system could be minimized at the 60% separating efficiency of brown rice separator. 3. In the alternative simulation the bottleneck of the system was minimized under the hulling capacity of 1 t/h and 60% separating efficiency of brown rice separator with the capacity of 1 t/h. Under such a condition the max. weight of waiting entities at buffer tanks was less 250kg. So, the capacities of the buffer tanks were determined in the basis of simulation results. 4. The milled rice recovery and head rice recovery of the milling system were 74% and 92% in the simulation, respectively. These results of simulation almost corresponded to those of actual rice mill plants. The developed simulation model could be well applied to design a rice mill plant.

  • To Know the factors required to make best quality of steamed rice with large amount of rice, several organizations that serve meals were surveyed. Factor that mostly influence the amount of water to the amount of rice is a kind or rice. In the case of good quality rice, when the amount of rice is more than 10cups, the ratio of water to rice is 0.9 and that of poor quality rice is 0.7 Average ratio is 0.8 Therefore, ordinarily with the ratio of 0.8, good quality of steamed rice can be made. Washed rice should be used to measured the of rice. To make a good quality of steamed rice with large amount of rice, center part of the boiling rice should be stirred generously several times to equalize the temperature.

  • We performed this experiment to select high quality rice adapted to wheat-rice double cropping system. We sowed barley and wheat seed in November 2, 2015. After harvesting barley and wheat, we transplanted high quality rice cultivars: 'Unkwang', 'Hopun', 'Haepum', 'Hyunoum' in June 17 and 24. We used 'sindongjin' rice as a control. As a result, 'Hyunpum' had a highest head rice yield regardless of transplanting date. Head rice yield of 'Hyunpum' was 488.1kg/10a when transplanted in June 17, and 453.6kg/10a when transplanted in June 24. The reason for this highest head rice yield was not percentage of head rice but milled rice yield. Milled rice yield of 'Hyunpum' was 526.5kg/10a when transplanted in June 17, and 490.0kg/10a when transplanted in June 24. Percentage of head rice had little differences between rice cultivars. Among yield components, only number of panicle per $m^2$ had an effect on the differences of yield between rice cultivars. The other yield components didn't have an effect on the differences of yield between rice cultivars. Compared to June 17, only 'Unkwang' had higher head rice percentage and head rice yield in June 24. Head rice percentage of 'Unkwang' changed from 67.3% to 85.0% and head rice yield changed from 324kg/10a to 393.8kg/10a when transplanting date delayed from June 17 to June 24. When transplanting date was delayed, heading date of 'Unkwang' was more delayed than other rice cultivars. By delay of heading date, mean temperature for 40days changed from $25.0^{\circ}C$ to $22.9^{\circ}C$ which improved temperature condition during grain filling stage. This improved head rice percentage and head rice yield of 'Unkwang' transplanted in June 24. If transplanting date is more delayed than June 24, 'Unkwang' could have higher head rice percentage and head rice yield. Therefore, if you transplant rice before June 24 in rice-wheat double cropping system, 'Hyunpum' is recommended as adequate rice cultivar. But if you transplant rice after June 24, further research is needed to find out adequate rice cultivar.
