Objects : Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) have been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Korean Traditional Medicine. In this research, we examined the effect of the extracts, obtained from EtOH extracts of 3 kinds of traditional plants, on hair growing activity of the DP6 and C3H10T1 cell and physical properties. Materials and Methods : On the basis of previous studies, three traditional plants were selected and we extracted them with ethanol. We evaluated their hairy dermal papillar cell proliferation activity and mouse mesenchymal stem cell in vitro model. Also, 3 herbal extracts were added to the normal shampoo formulation in ranges of 0.1% and we validated tensile properties and physical changes using aged hair. In this research, we compared the tensile strength, shine and color appearance between the hair (general formulation) and the hair after applying shampoo with natural extracts. To analyze the luster and color image, we use the SAMBA hardware and software made by Bossa Nova Technologies. Results : In the comparative test for tensile characteristic between the hair treated general formulation(control) and the hair applying special formulation including 3 kinds of extracts, tensile distance and energy of the latter are larger than control on average. The shine and color appearance were also increased after using shampoo including natural extracts(shine : 10.9%, color appearance: 24.12%). We observed the enhancement of hair growth activity in the DP6 and C3H10T1 cell. Especially black bean extracts had the most powerful effect in the dermal papillar cell proliferation. Conclusion : These experiments suggest that extracts of Glycine max Merr. (black bean), Triticum aestivum L. (wheat) and Oryza sativa L. (rice bran) stimulate the hair growth activity and can improve physical activities of aged hair. Shampoo product, which contains 3 kinds of natural extracts, would be used for the treatment for aged hair.
BACKGROUND: Some microorganisms extant in nature have ability to suppress various plant pathogens, and also can promote plant growth. Thus microorganisms are such great source of antimicrobial agents to develop antagonistic microorganism production and eco-friendly crop management. We isolated the microorganisms in various eco-friendly formulations. The suppressive abilities against plant pathogens have been characterized in vitro level. METHODS AND RESULTS: The indigenous microorganisms have been isolated from Cooked rice, Black sugar, Rice Bran, and Red clay using dilution plating method. Population of bacteria and fungi were above 107 in the all formulations. We isolated and pure cultured the microorganisms based on morphological characteristics. Three major plant pathogens (Fusarium oxysporum, Rhizoctonia solani, Phytophthora capsici) have been used to select antagonistic microorganisms. Total 20 bacteria and 9 fungi showed the pathogen growth suppression ability in vitro condition. The selected microorganisms were identified by ITS sequence similarity. CONCLUSION: All tested eco-friendly formulations contained high-density of the microorganisms. Among the isolated microorganisms, Bacillus spp. and Streptomyces spp. showed the most effective antifungal activity against the plant pathogens such as F. oxysporum, R. solani, and P. capsici. Among the selected fungi Trichoderma sp. demonstrated antifungal activity. Our results suggest that the currently adapted eco-friendly formulations might useful for sustain agricultural system.

This study was conducted to investigate the feeding fermented agro-industrial by-products on estimating the productivity and nutrient utilization of fattening black goats. Four experimental groups were set up with each of 6 animals for a 30 days feeding trial on growth performance and 12 black goats on nutrient digestibility were allocated to 4 groups of 3 animals each by latin-square design, control (offered concentrate and rice straw) and 3 treatment groups (offered fermentation feed and rice straw). Average daily gain (ADG) showed a significant high in control group, T3 was lower than other groups (p<0.05). DM and OM intake (kg/head) were 718.8, 680.9 g and 634.2~699.2 g, 602.8~660.4 g for control and treatment groups, respectively. As increasing of rice bran content was decreased feed intake. Digestibility of DM and OM for control group were significantly higher than treatment groups (p<0.05), and T3 treatment group with 30% rice bran was the lowest among treatment groups. Nitrogen retention was significantly higher in control and T1 groups. Thus, these results showed that productivity and nutrient utilization were similar between fermentation feeds with agricultural by-products and commercial feeds. However, this study was suggested that it must contain less than 5.0% crude fat because of feed efficient was decreased by increasing of rice bran content.

Rice production in Korea began to rise significantly after 1970. Rice is the dominant food in Korea and most of the rice production (about 95%) is consumed as cooked rice. it provides over 4,000Kj of energy per capita per day. Apparent rice availability in 2000, 93.6Kg of milled rice per person annually. The non-allergenic character of rice offers a sound basis for development of products for markets for all age groups. Whole grains are washed rice, coated rice, enriched rice in Korea. Utilization of rice as food can be categorized three categories in Korea; direct food use, processed foods, and brewing. Rice for direct consumption include regular whole grain, precooked rice, brown rice and specialty products such as aseptic cooked rice, retort cooked rice and rice burger. Rice used for processed foods includes that for cereal, soup, baby food, snack, cake, noodle, brown rice tea, and minor unclassified uses. Rice use for brewing is for the production of fermented rice wine. The use of rice for direct food is by for the greatest of the three uses. Although direct food accounts for the largest domestic consumption, a significant quantity of rice is used in processed products. The use of rice by-products as human food should not be over looked. Utilization of by products(rice germ, rice bran) requires a specialized technology. Typical type of rice is black rice. When cooked, black rice gives a black color to cooked rice. Glutinous rice performs specific functions in several commercial products such as dessert, gravis, cake and snack. Rice starch production is quite limited because of the high cost of making of starch. Rice processed products in Korea are occupied small parts of total rice production compared to Japan. Rice cake (Garadog) is the principal from of rice product consumed in Korea. Rice cake and snack is usually prepared from non-glutinous milled by washing, grinding, steaming, cooling and packaging. Rice cake will be continued to be a major rice product in Korea. Rice products represent a means to study variety differences in rice grain quality, since the processing magnifies differences not normally detected from more boiling. Recently, rice processing companies in Korea are about 400 ones which uses rice about 160,000tons. New rice processed products and modified traditional products must be developed and diversified with high quality and processing properties of rice processed products are improved.
Colored rices are a hulled grains having red or purple pigments in bran. Especially black rice (Heugjinjubyeo) is considered to be a healthy food in Asia. Black rice is of great interesting because of the possible biological activity with their anthocyanins. Anthocyanins are water-soluble plant pigments and representatives of flavonoids. The anthocyanins in black rice include cyanidin 3-O-glucoside, peonidin 3-O-glucoside, malvidin 3-O-glucoside, pelagonidin 3-O-glucoside and delphinidin 3-O-glucoside. In this study, anthocyanins in a black rice were analyzed quantitatively and qualitatively with HPLC and UV-Vis spectrophotometer. The anthocyanins contained approximately 95% of cyanidin-3-O-glucoside and 5% of peonidin-3-O-glucoside. Antioxidant activities of the anthocyanin extract were investigated by using various in vitro methods. The 100g/ml concentration of the anthocyanin extracted exhibited 88.83% inhibition on the peroxidation of linoleic acid, 55.20% DPPH free radical scavenging activity, 54.96% superoxide anion radical scavenging activity, and 72.67% hydrogen peroxide scavenging activity. And it also showed high ferrous ion reducing capability. These results suggest that the anthocyanin extracted from black rice may be utilized as a possible antioxdiant agent against ROS.
In order to reproduce Sanghwabyung that people in the past made and ate at Yuduil (June 6th by lunar calendar) among our traditional rice cakes, this study manufactured Sanghwabyung with black wheat flour by adding the wheat bran and Nuruk powder as leavening source, according to the old cook book "Gyuhapchongseo" and analyzed the quality characteristics. As a result of total phenol and flavonoid contents, DPPH radical scavenging activity of black wheat contents showed the gradual increase significantly (p < 0.001). The number of lactic acid bacteria was $6.72{\times}10^7$ CFU/mL just after preparation, and the number of yeast was $5.59{\times}10^7 $ CFU/mL. The number of lactic acid bacteria and yeast increased after 24 h to $8.48{\times}10^7$ CFU/mL and $5.40{\times}10^7$ CFU/mL. Hard-ness was the lowest in WF30%, compared with the C and the highest in BF100% and WF100%. The more the added portion increased in WF30% and BF30%, the more the hardness increased significantly (p < 0.001). The cohesiveness was the highest in WF30%, compared with C and BF30%, the lowest. It was shown significantly different between the C and WF and BF sample groups (p < 0.01). Springiness was the highest in WF10% and WF50%, compared with that in C and BF100%, which were the lowest. Springiness decreased significantly (p < 0.001) ad-ded portion increased between WF30% and BF30%. Gumminess was the highest in BF100% and WF100%, whereas that of WF20% was the lowest (p < 0.001). Chew-iness was the highest in BF100% and WF100% (p < 0.001).
The extraction of polyphenol and flavonoid from black rice bran was performed by diverse extraction methods using the sugar solution, ethanol, hot water ($80^{\circ}C$), and by subcritical water extraction (SWE) method. By SWE under operating conditions of $190^{\circ}C$, 1,300 psi, and 10 min, the maximum yields of total polyphenolic compounds (35.06${\pm}$1.28 mg quercetin equivalent (QE)/g dried material and flavonoids (7.08${\pm}$0.31 mg QE/g dried material) could be obtained. These results were over 11.77- and 12.21-fold higher than those of the ethanol extraction, which showed the highest extraction efficiency among tested conventional methods in total polyphenols (2.98${\pm}$0.74 mg QE/g dried material) and flavonoids (0.58${\pm}$0.21 mg QE/g dried material), respectively. Though the highest antioxidant activity (87.14${\pm}$1.14%) was observed at the dried extract obtained from ethanol method, the relative antioxidant activity per 1 g dried black rice bran by SWE ($190^{\circ}C$, 10 min) was over 11.53-fold higher than that by the ethanol extraction.
We assessed the GABA accumulation and other components after the 'Nunkeunhukchal (BGE)', 'Josanghukchal (BR)', and 'Ilmibyeo (IB)' grain was soaked in water for 24, 36, 48, 60, 72 and 96 hr. The results showed a continuous accumulation of GABA in soaking treated brown rice of BGE and IB. Among the treated hours, 72 hours of soaking had the maximal accumulation of GABA (51.4 mg/100 g), amino acid, polyphenol and other components. The activities of glutamate decarboxylase (GAD) in brown rice and rice-bran were the same in BGE rice. However, the formation of GABA treated with L-glutamate as substrate showed dramatic increase of 354.6 (fourteen times higher than normal extraction) and 726.4 mg/100 g in BGE rice and rice-bran, respectively. These results suggested that the soaking and extraction with L-glutamate buffer could be better methods for the harvest of increased GABA.

Dasik is a kind of traditional Korean dessert, which has polysaccharides as the major base. Dasik was prepared using rice and various ingredients and its antioxidant properties were determined. In addition, textural changes and sensory evaluation were conducted on Dasik during 7-day storage at $4^{\circ}C$. Dasik containing brown rice, red ginseng, and rice bran oil showed higher radical scavenging ability, reducing power, total flavonoid, and total phenolic contents among tested rice-based samples. Dasik prepared using black sesame seeds showed the highest radical scavenging ability and reducing power compared to rice-based Dasik. In sensory evaluation, 10 trained panelists found that hardness of the rice-based Omija Dasik sample increased significantly (P<0.05) while moistness and softness attributes decreased as the storage period of Dasik increased. The roasted bean Dasik and black sesame Dasik samples were evaluated similarly and their moistness decreased significantly (P<0.05) with longer storage period. The overall and texture acceptability of the rice-based Omija Dasik and the roasted bean Dasik samples decreased significantly (P<0.05), and scores of willingness to try again of the rice-based Omija Dasik decreased as the storage period of Dasik increased. Positive or negative correlations among the results from sensory evaluation and textural analysis were observed in Dasik.
Sunsik has been popular as well-being and healthy food to some Asian people, but it still has a limit to other foreigners because of its taste and appearance. This study tried to modify Sunsik into smoothie type for foreigners and investigate its physicochemical characteristics. Germinated black and brown rice was prepared. The germination condition of two cereals was steeping for 24 hr at room temperature, and then germinating for 24 hr at $30^{\circ}C$. After germination, the ${\alpha}$-amylase activity of germinated grains was 13~15 times higher than before germination. The enzyme activity of brown rice was 9.16 CU/g, but germinated brown rice was 152.63 CU/g. In case of black rice, enzyme activity before germination was 7.47 CU/g, and enzyme activity after germination was 97.96 CU/g. The lactic acid bacteria was grown in 50 g germinated brown rice powder with 100 ml malt solution, 30 g tomato juice, and 1.5 g rice bran. After manufacturing beverage using milk and Sunsik and the cell count of lactic acid bacteria was $1.3{\times}10^5CFU/ml$ enough to use starter. According to sensory test, the optimal concentration of Sunsik smoothie was 30 g Sunsik in 200 ml of milk. The viscosity was $5.97{\pm}1.2$ centipoise. The color of Sunsik beverage was evaluated as L value : $63.50{\pm}0.41$, a value: $-0.35{\pm}0.06$, and b value: $8.85{\pm}0.19$.
