  • In this study, we examined whether the glycemic index (GI) values of boiled white rice (GI=86) and boiled white rice mixed with grains (GI=58) could influence the total energy intake and satiety rate of a rice-based diet. Thirty adult females participated in this study, in which they ate boiled white rice, or boiled white rice mixed with grains, along with side dishes for lunch, and then ate the same white rice diet for dinner in the lab once a week for 2 weeks. There was no significant difference in the visual analogue scales for taste between the two diets. Although there were no differences between the subjects' energy intakes for side dishes, the total energy consumed from the boiled white rice mixed with grains diet (520.5 kcal) was significantly (p<0.001) lower than that consumed from the boiled white rice diet (560.2 kcal). For dinner, the subjects consumed significantly (p<0.001) lower calories when they had eaten the boiled white rice mixed with grains diet for lunch as compared to the boiled white rice diet. In addition, the subjects reported significantly (p<0.01, p<0.001) higher satiety rates after consuming the boiled white rice mixed with grains diet compared to the boiled white rice diet, despite consuming lower calories. In conclusion, these results indicate that consuming low GI rice such as boiled white rice mixed with grains substituted for boiled white rice, may be a useful strategy for weight loss and weight management since individuals will consume less energy without experiencing a reduction in satiety.

  • Objectives: This study was conducted to examine the relationship between white rice and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults. Methods: Dietary intake and health data of 8289 subjects aged 19 years and over from the 2013-2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used. Daily total intake of white rice and Kimchi was assessed by 24-hour recall data. Multivariate logistic regression analysis was used to estimate the risk of Mets according to the daily intake of white rice and Kimchi. Results: The highest intake of white rice and Kimchi was associated with a higher risk of metabolic syndrome (Q1 vs Q5, multivariable adjusted OR=1.45, 95% CI: 1.03-2.03) in women. In addition, a significantly increased risk of elevated blood pressure (multivariable adjusted P for trend 0.0459) was associated with a higher intake of white rice and Kimchi in women. There was no significant trend in the risk of metabolic syndrome according to the intake of white rice and Kimchi in men. Conclusions: A higher intake of white rice and Kimchi was only associated with an increased risk of metabolic syndrome in women indicating it is necessary to consume more various food groups beside white rice and Kimchi, especially in women.

  • 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.

  • Purpose: This study was conducted to identify the association between insulin resistance and the major dietary patterns of Korean adults. Methods: This study used data from the 2015 Korea National Health and Nutrition Examination Survey. The subjects were 2,276 adults aged 19 to 64 years old. Based on the food frequency questionnaire data, 112 food items were reclassified into 30 food groups. The principal component analysis method was applied to identify major dietary patterns. We used homeostatic model assessment of insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) value as indicators of insulin resistance. The association between major dietary patterns and insulin resistance was investigated using logistic regression analysis. Results: Three major dietary patterns were identified and assigned descriptive names based on the food items with high loadings: 'healthy Korean meal pattern', 'western meal pattern', and 'white rice, alcohol, meat pattern'. As the 'white rice, alcohol, meat pattern' score increased, significant increasing trends for fasting glucose concentration and HOMA-IR and a significant decreasing trend for QUICKI were observed after adjusting for age and sex. The odds ratio of insulin resistance according to the 'healthy Korean meal pattern' and the 'western meal pattern' were not statistically significant. the 'white rice, alcohol, meat pattern' showed a significant positive association with the risk of insulin resistance after adjusting for covariates. Conclusion: These results suggest that the 'white rice, alcohol, meat pattern' is positively associated with the risk of insulin resistance. The white rice, alcohol, meat pattern was related to the high consumption of alcohol together with rice or meat. This pattern was also associated with the high intake of sodium and low intakes of vitamin C, calcium, potassium, and dietary fiber. To confirm the association, further longitudinal studies are required.

  • The objective of this study was to determine the optimal conditions for preparation of cooked brown rice by blending brown rice, white rice and glutinous rice to improve the palatability. Formulations composed of brown rice (10~100%), white rice (0~90%) and glutinous rice (0~90%) were generated from an extreme-vertices of mixture experimental design, which showed ten experimental points for brown rice, with white rice and glutinous rice as the independent variables. The sensory evaluation, color, and texture profile analysis (TPA) of cooked brown rice and pasting characteristics of blending cereals flour were measured as response variables. Regression analysis showed that all responsible variables fit linear, quadratic or special cubic models (p<0.1), except for the cohesiveness of TPA. The goals of optimization of the blending ratio of brown rice, white rice and glutinous rice were given as appearance, flavor, texture and overall acceptability (lower: 5.50, target: 6.62). The optimal conditions were determined to be 34.55% brown rice, 42.71% white rice and 22.74% glutinous rice.

  • The purpose of this research was to investigate the relationship between white rice consumption and dietary intake, the risk of metabolic syndrome in Korean based on $1^{st}$ (1998), $4^{th}$ (2007~2009), $6^{th}$ (2013) KNHANES. This study included 25,799 subjects who were age 10 or over. Three groups(low, medium, high) were divided according to white rice consumption (per day). In the low group, the meat and oil intake were significantly higher than the high group. In the $1^{st}$ survey year, the BMI, waist circumstances, hypertriglyceridemia and fasting blood glucose in the high group were higher than other groups, however the $4^{th}$ and $6^{th}$ survey year showed no significant results. In the $1^{st}$ survey year the risk of waist circumstances was higher in the high white rice consumption group and also had high risk with hypertriglyceridemia. Since the lower white rice consumption in $4^{th}$ than $1^{st}$ survey year we found no significant results. But in the 6th survey year with the lowest white rice consumption the risk of high diastolic pressure was reduced in high group. Because continuously reduced white rice consumption meantime showed more intake of meat and oil, it can be concluded that defensive effects with the Korean health.

  • White rice consumption, a staple food for the Korean influence the other food consumption and nutrition balance. The aim of this study was to investigate the association with rice consumption based dietary intake and muscle mass for the Korean elderly who are easily in mal-nutrition. A total of 1,433 subjects (658 male and 775 female) 60 years or older from the fifth Korea National Health and Nutritional Examination Survey 2010 participated in this study. One of the findings was that there was association white rice consumption and marital status (single/with/without spouse) as well as education for men. Other interesting finding was the member of highest white rice consumption group showed higher muscle mass in both sexes. The other finding was that the more white rice consumption group showed the less meat consumption as well as the less consumption of other grains, noodle & dumpling, and flours & bread in both sexes. We found the significant association between white rice consumption level and muscle mass and several metabolic syndrome related factors in the elderly. But the association with white rice consumption and glucose metabolism related factor had not shown consistently.

  • Digestion properties of 3 types of cereals, white rice, brown rice, and barley, were measured after cooking or grinding. Regardless of the processing methods, white rice showed the highest rate and the greatest extent of digestion, whereas barley showed the lowest values. During the early digestion period, cooked white rice kernels had a larger k (kinetic constant) value than uncooked white rice flour, indicating that cooking induced faster digestion than grinding. In the case of brown rice and barley, the cell wall in cooked kernels remained intact and resulted in a lower k values than those of uncooked flour. However, after 3 hr of digestion, the total digestion extent was greater for the cooked brown rice and barley than that for uncooked flours. The high content of slowly digestible starch (SDS) in cooked brown rice and barley might be due to the starch fraction which was protected by the cell wall. The resistant starch (RS) content, however, was greater for the uncooked flours than that for cooked kernels. The cooked kernels of 3 cereal samples tested showed higher glycemic index (GI) values than the uncooked flours.

  • To address the limitations of manufacturing noodle products using rice, brown rice noodles were created by the fermentation of brown rice containing several nutrients and the quality of these noodles were evaluated. White rice noodles, fermented white rice noodles, brown rice noodles, and fermented brown rice noodles were developed using white rice and brown rice, respectively. We found that the content of crude proteins present in the noodles during the fermentation process increased and the content of crude fat and carbohydrates in the noodles was reduced. In addition, the water content of brown rice noodles was twofold higher than that of white rice, although under fermentation conditions, the water content of brown rice noodles decreased slightly. A slight change of chromaticity was observed during the fermentation process. In cooking, the weight and volume of the noodles increased, with the change being lowest in noodles based on white rice. White rice-based noodles exhibited significantly higher turbidity in the cooked noodle soup, while other noodle products showed relatively constant turbidity. Most of the products showed a decreased texture, becoming soft with cooking; however, the elasticity of the cooked products increased. Our results suggest that the disadvantages of producing rice noodles can be overcome by the development of fermented brown rice noodles containing a variety of nutritional components. This would potentially develop a market for rice-based manufactured foods that appeal to modern preferences.
