  • This study investigated the status of mixed grain diet by 68 people with diabetes living in Jeollabuk-do and performed sensory evaluation of different composition of mixed grains to improve the sensory characteristics based on the investigation. BMI of all subjects were measured and found that 61.7% were overweight. 94.1% of them ate mixed grains and females ate more mixed grains than males (p<0.05). Most males and females answered that they ate mixed grains for their health. Females added more mixed grains than males (p<0.01). More females (47.1%) than males said they would continue to eat mixed grains (p<0.05). 59% of them said they had eaten mixed grains for more than 3 years. 46.0% of them said they purchased mixed grains at a small mart near their houses. The mostly added grain to rice was black soybean (76.5%). RMGD-50 is composed of six mixed grains excluding nonglutinous rice and has the mixing rate of 50%. RMGD-40 has the mixing rate of 40%. Sensory evaluation was performed and RMGD-50 got lower score ($3.33{\pm}0.68$, $3.50{\pm}0.81$) than RMGD-40 in the appearances and color. RMGD-40 with Control 1 that includes more glutinous grains and Control 2 that is polished rice were compared. RMGD-40 got lower score than Control 1 in its appearances, smell and color, although there wasn't a meaningful difference. For the people with diabetes who are accustomed to mixed grains, the polished rice got the lowest score in moisture amount, gumminess and overall taste ($3.26{\pm}0.82$, $3.48{\pm}0.85$, $3.19{\pm}0.70$). It showed meaningful difference from RMGD-40 and Control 1 (p<0.01). Consequently people with diabetes preferred mixed grains that include more glutinous grains that have lower mixed ratio. So it is necessary to educate the people with diabetes about eating grains for better blood sugar management. Continual study and development of mixed grains that can help people with diabetes to control their blood sugar are necessary.

  • This study evaluated the quality characteristics, the presence of polyphenolic compounds, and radical scavenging activity of rice cooked along with various mixed grains (barley, black soybean, adzuki beans, foxtail millet, proso millet, sorghum, glutinous rice) by following two different cooking methods (normal and pressure cooker). The amylogram and water characteristics of mixed grains showed significant differences based on the presence of different types of mixed grains. The chromaticity, palatability characteristics, presence of phenol compounds, and radical scavenging activity of rice cooked along with different mixed grains showed significant differences according to the nature of mixed grains. Total polyphenol contents of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker were 4.46~5.16, 0.58~0.93 and 0.65~0.96 mg GAE/g, and total flavonoid contents were 250.74~548.89, 129.26~207.04 and $127.41{\sim}218.15{\mu}g\;CE/g$, respectively. The DPPH radical scavenging activity of before cooking, cooked-rice added to mixed grains cooked in the normal cooker and a pressure cooker was 79.25~181.61, 22.07~53.64 and 7.51~39.97 mg TE/100 g, and ABTS radical scavenging activity was 203.25~328.24, 47.28~84.94 and 58.27~99.51 mg TE/100 g, respectively. Accordingly, it is necessary to different combinations of mixed grains according to the cooking method at home and grain industry.

  • The purpose of this study was to investigate the levels of antioxidant activities in some traditional and a few super food mixed rice. Amongst nine chosen samples, traditional five grains were analyzed and results revealed highest content of crude-protein ($8.05{\pm}1.11%$) and lowest crude-fat content ($1.74{\pm}0.29%$); however, the calories was found to be relatively low ($358.05{\pm}0.34kcal$) in the samples. Total polyphenols, flavonoids and tannins were extracted from nine samples with 80% methanol and biochemical activity was measured. The content of total polyphenols, flavonoids and total tannin was $206.5{\sim}452.0{\mu}g/mL$, $0.126{\sim}0.340{\mu}g/mL$, and $548.1{\sim}774.8{\mu}g/mL$, respectively. The traditional five grains showed the highest values except for DPPH radical scavenging activity. DPPH radical scavenging activity was 5 to 40.3% higher in eight samples than the traditional five grains sample. From these results, it is conjectured that a mixture of five grains, might exhibit equal or considerably higher effect as healthy diet when compared to super food. The results from this study would serve as basic data for the use of traditional mixed grains rice diet for good health.

  • Three experiments were carried out to evaluate the fermentation process and subsequent nutritional quality of silage made from dried and fresh barley straw with and without the addition of wet brewers' grains. The treatments were: 1 kg of dried straw with 600 g of water but no wet brewers' grains (I - 0) as a control, and the same straw mixed with 2 kg (I - 2), 3 kg (I - 3), 4 kg (I - 4), or 5 kg (I - 5) of wet brewers' grains as treatments in Experiment I; and 2 kg of fresh straw without wet brewers' grains (II - 0) as a control, and the same fresh straw mixed with 2 kg (II - 1), 4 kg (II - 2), 6 kg (II - 3), or 8 kg (II - 4) of wet brewers' grains as treatments in Experiment II. Each material prepared was ensiled in 5 L (vinyl) bag silos, and the silos placed in a chamber of $21^{\circ}C$ for 10 (Exp. I) or 7 (Exp. II) months. The fermentation quality and nutritive value of the barley straw silages produced were markedly improved by mixing them with wet brewers' grains. Increasing levels of wet brewers' grains caused on increase in fermentation quality. The in vitro dry matter digestibility of silages was also increased by adding wet brewers' grains. Two semi scale pilot silages, experiment III, prepared from dried and fresh barley straw mixed with wet brewers' grains were fed to wether sheep. These silages, which contained 50% barley straw and 50% wet brewers' grains by dry weight, were moderate apparent digestibility and supplied of about 50% TDN and DCP.

  • 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.

  • Barley, wormwood, sea tangle, and soybean were fermented by Bacillus licheniformis B 1 to make Chungkookjang with better flavor and aroma. Maximal protease activity in mixed grains was observed one day after inoculation. pH increased to 8.4 two days after inoculation. Browning material derived from interaction between sugar and amino acids increased 20-fold. Thus, it is proved that Chungkookjang can be made in the mixed grains. Antioxidant activities of mixed fermented grains dissolved in ethanol or methanol (0.2 and 1 %) increased depending on their concentrations. Antioxidant activities were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH). One % of powder Chungkookjang dissolved in methanol showed highest antioxidant activity. Systolic blood pressure of hypertensive volunteers who took 20 g of mixed fermented powder decreased on average by 10 mmHg in 2 h. Preference of mixed fermented soybean containing barley, wormwood, sea tangle to fermented soybean was demonstrated by t-test analysis. Mixed fermented grains can be developed as a functional food to lower hypertension.

  • In this study, intermediate-mixed powders were prepared by loading zirconia powders initially in a ball-mill jar and loading alumina powders afterward; the initial-mixed powders were produced by loading zirconia and alumina powders together in the ball-mill jar. The effect of such differences in mixing method on the mechanical properties was investigated. In intermediate-mixed powders, the volume fraction of large particles slightly increased and, simultaneously, zirconia particles formed agglomerates that, due to early ball-mill loading of the zirconia powders only, were more dispersed than were the initial-mixed powders. For the intermediate-mixed powders, zirconia agglomerates were destroyed more quickly than were initial-mixed powders, so the number of dispersed zirconia particles rose and the inhibitory effect of densification due to the addition of a second phase was more obvious. In the microstructure of intermediate-mixed powders, zirconia grains were homogeneously dispersed and grain growth by coalescence was found to occur with increasing sintering temperature. For the initial-mixed powders, large zirconia grains formed by localized early-densification on the inside contacts of some zirconia agglomerates were observed in the early stages of sintering. The intermediate-mixed powders had slightly lower hardness values as a whole but higher fracture toughness compared to that of the initial-mixed powders.

  • This study evaluated the quality characteristics, polyphenolic compounds, and radical scavenging activity of cooked-rice added to commercially available mixed grains. L-value of cooked-rice with various mixed grains decreased compared to that of cooked-white rice; however, a- and b-values increased. Hardness and elasticity of cooked-rice added to various mixed grains were significantly lower in the pressure cooker compared to the electric cooker. There was no significant difference in adhesiveness and stickiness between rice from the electric cooker and pressure cooker. Total polyphenol and flavonoid contents of cooked-rice added to various mixed grains were significantly increased. The average total polyphenol content of cooked-rice added to various mixed grains cooked in an electric cooker and pressure cooker were $16.50{\pm}3.86$ and $15.88{\pm}3.52mg$ gallic acid equivalent /100 g, and flavonoid contents were $1.58{\pm}0.00$ and $1.55{\pm}0.02mg$ catechin equivalents/100 g, respectively. The average of 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was $9.27{\pm}2.62$ and $8.72{\pm}2.41mg$ trolox equivalent (TE)/100 g, and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity was $22.89{\pm}4.60$ and $23.07{\pm}4.49mg$ TE/100 g for cooked-rice added to various mixed grains cooked in an electric cooker and pressure cooker, respectively. Phenol content and radical scavenging activity of cooked rice was in proportion to the amount of added grains, such as brown rice, colored rice, barley, soybean, and sorghum.

  • The main sources of interstellar dust are believed to be dust envelopes around AGB stars. The outflowing envelopes around the long period pulsating variables are very suitable place for massive dust formation. Oxygen-rich silicate dust grains or carbon-rich dust grains form in the envelopes around AGB stars depending on the chemical composition of the stellar surface. The dust grains expelled from AGB stars get mixed up and go through some physical and chemical changes in interstellar medium. There are similarities and differences between interstellar dust and dust grains in AGB stars. The mass cycle in the Galaxy may be best manifested by the fact that the dust grains at various regions have many similarities and understandable differences.

  • This study determined the substitution effects of rice for corn as the main grain source in a total mixed ration (TMR). In vitro rumen fermentation characteristics and microbes were assessed using two experimental diets. Diets included 33% dry matter (DM) of either corn (Corn TMR) or rice grains (Rice TMR). In a 48-h in vitro incubation, DM digestibility (IVDMD), neutral detergent fiber degradability (IVNDFD), crude protein digestibility (IVCPD), volatile fatty acids (VFAs), pH and ammonia nitrogen (NH3-N) were estimated. Gas production has been calculated at 3, 6, 12, 24 and 48 h. Our results indicate that the gas production, VFAs, IVDMD, and IVNDFD of Rice TMR were higher than those of Corn TMR (p < 0.05). Ruminal pH and total fungi were significantly higher in Corn TMR (p < 0.05) than in Rice TMR; however, NH3-N and IVCPD were not affected by treatment type. In conclusion, substituting rice for corn at 33% DM in TMR appears to have no negative effects on in vitro rumen fermentation characteristics. Therefore, rice grains are an appropriate alternative energy source in early fattening stage diets of beef cattle.
