  • In this study, rice was used with naturally fermented extract to compare and analyze the physico-chemical characteristics and investigated how to make pan bread made with domestic wheat flour added with naturally fermented rice extract. Also, it examined quality characteristics of pan breads prepared with 0, 10, 30, 50, 70% naturally fermented rice starters. As the fermentation time of rice starters increased, pH of bread doughs decreased. On farinograph, water absorption, development time and stability of rice starters samples were lower than the control. RVA(Rapid Visco Analyzer) analysis showed that wheat flour retrogradation was retarded by increasing rice starters content. The weights of pan breads containing rice starters were higher than that of control. The moisture content of pan breads containing rice starters decreased as storage time increased. In analyzing of visible mold colony during 7 days of storage at $28^{\circ}C$, pan breads containing rice starters was retarded mold growth. In the texture analyzer measurement, hardness of breads containing rice starters significantly increased as storage time increased, which was higher than that of control. The result of sensory properties was no significant difference between the group containing 50% naturally fermented rice starters and control group, such as appearance, flavor, taste and overall quality.

  • This study was carried out to evaluate the effects of black sesame powder on bread quality. Breads were prepared by the addition of 0, 2.5, 5.0 and 7.5% of black sesame powder to the basic formulation. The weight of bread with black sesame powder ranged from 522.0 to 532.0 g and that of the control was 516.0 g. The volume of the bread prepared by adding 2.5, 5.0 and 7.5% black sesame powder was 2250.0, 2290.0, and 1800.0 mL, respectively. The water absorptive rate of bread with added black sesame powder decreased 3.83 to 2.48 and that of the control was 5.28. The lightness, redness and yellowness values of the bread decreased with the increase of black sesame powder. The hardness increased with the addition of black sesame powder, and was the highest for the bread with added 7.5 % black sesame powder. The sensory quality of the black sesame powder-bread as estimated by taste, and overall acceptability was better than that of the control product, and especially the quality of the bread with the addition of 2.5% black sesame powder was the best.

  • In order to elucidate the ecological and phenological responses of bean under global warming situation, we investigated leafing and flowering phenomena and growth traits of Baktae and Seomoktae in control plot (ambient $CO_2$ concentration and temperature) and warmed plot (elevated $CO_2$ concentration and increased temperature than control) in green house. Average $CO_2$ concentration and temperature were set 540 ppm in treatment and higher $2.2^{\circ}C$ in treatment than control. The appearance of leaf unfolding and the initiation of blooming and fruit maturing in Seomoktae were late in treatment than control. In case of Baktae, the number of total pods and seeds per plant in treatment was fewer than that in control. For Seomoktae, the number of total pods per plant and weight of total seeds per plant were decreased in treatment than in control. Thus, the number of pods and seeds of Baktae declined and the production of Seomoktae was decreased under global warming condition. This result indicates that site selection and crop yield for cultivating of the bean may be changed into new area due to global warming condition.

  • Herbs have active components that promote the growth rate of both animals and human. The KI-180 and KI-188 calcium food formulae contain Acanthopanacis cortex, Bombysis corpus and hoelen, seaweed calcium, chlorella extract, spirulina, colostrum powder, and other natural and functional components. We evaluated the growth-promoting effects of these formulae by analyzing the weight, femur and backbone, alkaline phosphatase, osteocalcin, testosterone, insulin-like growth factor (IGF)-1, and IGF binding protein-3 (IGFBP-3) of growing rats. Growing rats administered with KI-180 and KI-188 calcium showed the increase of body weight, body length, and femur weight and length of growing rats. In addition, administration of KI-180 and KI-188 calcium increased the alkaline phosphatase activity, the levels of osteocalcin and the growth hormones IGF-1 and IGFBP-3 of growing rats. The impact of KI-180 and KI-188 calcium on the physical development of growing rats suggests that the incorporation of these food formulae in the diets of growing children may promote the physical development.
