  • 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.

  • 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.

  • In order to understand the growth and ecophy -siological response of ginseng to global warming condition, we cultivated one and two year ginseng seedlings in control (ambient $CO_2$ + ambient temperature) and global warming treatment (elevated $CO_2$ + elevated temperature) from March 2010 to July 2011. Shoot appearance and initiation of flowering were advanced by 3-4 days in global warming treatment than in control. However, timing of fruit setting and seed ripeness was similar in both control and global warming treatment. Shoot length was longer in global warming treatment than in control, and also the number of leaves was much in global warming treatment. Fresh root weight was not different between control and global warming treatment. Photosynthetic rate was higher in global warming treatment than at control. Photosynthetic rate and transpiration rate were higher in two year seedlings than in one year seedlings at control, but was not different between seedling age of ginseng in global warming treatment. Water use efficiency was higher in one year seedlings than two year seedlings at control and global warming treatment. These results demonstrated that Korean ginseng more or less positively responds to global warming situation.

  • The current study was conducted to investigate the effect of high quality hay on the performance and carcass characteristics of Hanwoo steers. Twenty(20) Hanwoo(7 months old) were allocated into either Control(rice straw fed) or Treatment(timothy hay and rice straw fed) group(10 animals per group) and fed for 710 days until the animals reached at 30 months old. Concentrates were fed according to the feeding program composed with three(3) phases; growing, fattening, and finishing period. For the overall feeding period, final body weights were 761.3 and 799.6kg for the Control and Treatment groups, respectively, showing 38.3kg heavier body weight in Treatment group. ADG were 0.79 and 0.84kg for Control Treatment groups, respectively. These results might be because of the intake of high quality hay during growing phase and the effects persisted until the end of the experiment. Feed intake tended to be higher in Treatment group whereas feed conversion did not show significant difference between groups. Cold carcass weights were 451.0 and 475.3kg for Control and Treatment, There were no significant difference between groups in both yield and quality grade. There were no remarkable differences in physico-chemical characteristics fatty acid composition of carcasses between groups. In conclusion, it would be beneficial to feed high quality hay such as timothy during growing period of Hanwoo steers to produce high quality beef with heavier live and carcass weight.

  • In this study, we evaluated the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 5, 7 and 9%) of broccoli (Brassica oleracea var. italica Plenck) powder. Cookies containing broccoli powder evidenced significantly lower L value than were noted in the control. The L values of brightness decreased significantly with the addition of broccoli powder to the cookie formula. The a values also decreased significantly with the addition of broccoli powder. The b value of yellowness increased significantly with increasing amounts of broccoli powder added to the cookie formula. The spread ratio increased proportionally with the quantity of broccoli powder added to the cookie formulation. The loss rate and leavening rate of the samples to which 7% and 9% broccoli powder was added were higher than those noted in the samples to which 3% and 5% broccoli powder was added. In terms of hardness, the values were significantly reduced in accordance with the amount of added broccoli powder. The results of our sensory evaluation demonstrated that the sample to which 7% powder was added was significantly more preferable in terms of overall acceptability than others. The quality characteristics of the 7% added samples evidenced significantly similar or higher values as compared to those of the controls, raising the possibility of developments in health-functional cookies.

  • The objective of this experiment was to compare tile effect of feeding the commercial feeds (control) or fermented food waste feeds (FEWF) on consumer's acceptability and preference of pork belly. The bellies from carcasses of gilts and barrows were used. The consumers evaluated raw meat for color, freshness, fat amount (5=too much fat; 1= not enough fat), fat acceptability and overall acceptability on 5-point stale (5=most desirable; 3=moderate; 1=least desirable) and grilled belly for flavor, taste, texture, juiciness and overall acceptability on 5-point scale (5=most desirable; 3=moderate: 1=least desirable). Raw belly of control had higher scores in color than belly fed FFWF. However, there were no differences between treatments for freshness, fat contents, acceptability of fat contents and overall acceptability (p>0.05). There were no differences in any sensory trait between control and FFWF belly after cooking (p>0.05). Mean scores for preference or overall-liking of raw and cooked belly also were not significantly different between two groups (p>0.05). This results mean that feeding FFWF to pork didn't change the sensory Properties of belly meat.
