  • 본 연구에서는 비열 및 열처리에 따른 5종류의 보리 품종별 알코올발효 특성을 조사하였다. 비열처리구에서 알코올 함량은 쌀보리, 찰쌀보리 및 흰찰쌀보리가 각각 1.7, 2.9 및 4.3%로 나타났으며 보리와 찰보리는 발효가 되지 않았다. 열처리구에서 비열처리구에 비해 전반적으로 골은 알코올생성능을 보였다. 당도는 비열처리구의 보리 및 찰보리가 $9.0\;^{\circ}Brix$ 전후의 높은 당도를 나타내었고 쌀보리, 찰쌀보리, 흰찰쌀보리가 $5.0\;^{\circ}Brix$ 전후의 당도로 나타났다. 열처리구의 당도는 알코올생성능과 반비례 경향이었으며 알코올발효 종료 후 쌀보리를 제외하고는 당함량이 50%이상 감소되었다. 비열처리구에서 산도는 흰찰쌀보리가 0.51%로 나타났으며 나머지 시료들은0.80%이상의 수치를 보여 산패의 가능성을 보였고, 열처리구에서는 모든 시료들이 0.3%이하의 수치로 나타났다. 유리당은 비열처리구의 보리와 찰보리가 알코올을 생성하지 않았으므로 유리당 총함량은 4,000.0 mg%전후로 높게 나타났고 쌀보리, 찰쌀보리 및 흰찰쌀보리는 300.0mg%전후의 함량으로 나타났다. 열처리구에서는 당도가 높을수록 유리당 총 함량이 높게 나타났으며 이상의 결과 보리는 열처리에 비해 비열처리 알코올 발효에는 적합하지 않았다.

  • Barley proteins are expected to have unique functional properties due to their high content of alcohol soluble protein, hordein. Since the barley proteins obtained by conventional isoelectric precipitation method cannot represent hordein fraction, barley proteins were fractionated to albumin, globulin, glutelin, and hordein with respect to extraction solvents. Functional properties and film-forming properties of solubility-fractionated barley proteins were investigated to explore their potential for human food ingredient and industrial usage. The 100 g of total barley protein comprised 5 g albumin, 23 g globulin, 45 g glutelin, and 27 g hordein. Water-binding capacities of barley protein isolates ranged from 140-183 mL water/100 g solid. Hordein showed the highest oil absorption capacity (136 mL oil/100 g), and glutelin showed the highest gelation property among the fractionated proteins. In general, the barley protein fractions formed brittle and weak films as indicated by low tensile strength (TS) and percent elongation at break (E) values. The salt-soluble globulin fraction produced film with the lowest TS value. Although films made from glutelin and hordein were dark-colored and had lower E values, they could be used as excellent barriers against water transmission.

  • New winter wheat winter barley hybrids were produced (Mv9 kr1 Igri, Mv9 kr1 Osnova, Asakazekomugi Manas). The wheat-barley hybrids showed entire male sterility and were multiplied in tissue culture. Chromosome configurations were studied with GISH in meiosis in the Mv9 krl x Igri hybrid and in its progenies multiplied in vitro. Chromosome pairing between wheat and barley has been observed in some cells in the hybrids multiplied in vitro. Backcross plants with 43 and 44 chromosomes were selected with the aim of developing new wheat-barley addition lines. Wheat-barley translocations were demonstrated with GISH in backcross progenies originating from in vitro regenerated wheat (Triticum aestivum L. cv. Chinese Spring) x barley (Hordeum vulgare L. cv. Betzes) hybrids. Five different translocations were observed. Sequential N-banding and GISH analyses were performed to further identify the translocations. The N-banding pattern of the Robertsonian translocation suggests that this chromosome consists of the short arm of barley chromosome 4H translocated to the long arm of 2B of wheat. Plants with four different homozygous translocations were selected from the following BC2F3 generation.

  • Effects of the addition of \beta-glucanase to barley-based layer diets were examined by feeding 200 Leghorn layers with corn-based (Control) and \beta-glucanase supplemented diets (Barley+ Enzyme). The results obtained are sumrrarized as follows. 1. There were no siginificant (P>0.05) differences in hen-day egg production(%) and average egg weight between two treatments, indicating that the \beta-glucanase supplemented barley could successfully replace the commonly used corn in the layer diets. 2. Although there was no statistical difference (P>0.05) between two treatments, the daily feed consumption was numerically high in layers fed the barly diet compared to the corn-based diet. 3. Availabilities of crude fat and crude fiber of the barley diet were significantly poor (P<0.05) as compared to corn diet. 4. The \beta-glucarase supplementation depressed the viscosity of barley diets and excreta from therm. 5. Both serum and egg yolk cholesterol were not significantly affected by the addition of \beta-glucarase in the barley based diet. Our data indicate that the barley grain supplemented with \beta-glucarase can be sucessfully used as an energy source of layer diet when there is a price advantage. Although some possibilities to produce low cholesterol egg were recognized in this study, further studies pertaining to long-term feeding experiment and elucidaton of the metabolic interrelationship between serum and yolk cholesterol, are required to confirm the result.

  • Barley or corn tea, which is usually prepared with municipal chlorinated tap water, is commonly consumed by the public as a substitute for the supplied water itself. This is because most people believe that harmful organic and inorganic compounds can be removed from the tap water by the adsorption mechanism during the tea preparation. In this study, three kinds of commercial grain tea materials-roasted barley grains, a tea bag containing barley grain pieces, and roasted corn grains-were tested for metal removal by preparing 1 liter of tea with deionized/distilled water according the manufacturer's recommended preparation procedures, assuming that the water is contaminated with eight selected metals at levels of 50$\mu\textrm{g}$/l. Of the tested teas, barley tea prepared with roasted grains showed the highest removal efficiency for Cu, As, Ni, Co, Pb, and Cd, ranging from 48 to 71%, followed by corn tea with roasted grains and barley tea with a tea bag. Cr was nearly maintained at the initial concentration in all kinds of tea. The Mn levels. however, were elevated during the tea preparation, particularly in both barley teas, probably because the metal was extracted into the water from the tea materials without significant adsorption. Therefore, it should be considered in the ingestion exposure analysis for metals that their concentrations are altered during the tea preparation with roasted barley or corn grain materials.

  • This study was conducted to observe the fermentative quality and anthocyanin content in whole crop colored barley silage during storage periods and anthocyanin stability in in vitro ruminal fluid. Silages of colored barley cultivar "Boanchalbori" and normal barley cultivar "Yuyeonbori" were stored during 0, 2, 4, 6, and 12 months. The in vitro ruminal fluid was fermented for 0, 6, 12, 24, and 48 hrs. For the feed value, crude protein of colored barley silage was slightly increased in the silage compared to that of normal barley silage, and being increased up to 2 months after ensiling and thereafter maintained at the similar level. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of both the barley significantly increased by prolonged storage of 2 months (p<0.05), but they were maintained at the constant level after 2 months of storing silage. Whereas TDN (total digestible nutrients) contents of them were decreased by the prolonged storage of 2 months (p<0.05), then maintained at the constant levels. The fermentative quality and pH values in both the barley silages were slightly decreased during the storage time. Lactic acid and acetic acid contents were increased during prolonged storage period, but not significantly different among treatments. Butyric acid was not detected. In the colored barley silage, pH value showed slightly lower compared to that of the normal barley silage but not significant, and lactic acid content was significantly higher than the normal barley silage (p<0.05). The total anthocyanin content in the whole crop colored barley silage decreased to 42% after 2 months of ensilage, however maintained at the constant level until 12 months of ensilage. In the case of anthocyanin stability on in vitro ruminal fluid digestion, the pH value of the ruminal fluid was slightly lower at 6, 12, 24, 48h incubation time and the content of anthocyanin was at similar levels. These results indicated that the colored barley showed higher fermentation quality, and total anthocyanin content was maintained stable at 42% level of the first value in storing silage. As the anthocyanin had higher stability in the ruminal fluid, the colored barley has a potential as functional feeds for Ruminants.

  • This investigation was carried out to clarify the changes of pigments and soluble protein, and photosystem II activity in the leaves of barley (${SO}_2$-sensitive) and corn (${SO}_2$-resistant) seedlings induced by the ${SO}_2$ fumigation (10, 50ppm). The pH changes of the leaf extract, the content of sulfite and sulfate, the activities of catalase, peroxidase, and polyphenoloxidase were compared in the leaves of barley and corn seedlings induced by ${SO}_2$ fumigation. The results are summarized as follows: An appreciable effect of pH change of leaf extract by ${SO}_2$ fumigation was observed in barley leaves (pH 6.10 to 5.18), but only a small change occurred in corn leaves (pH 5.66 to 5.50). The same pattern of pH changes was recorded when the solution of 0.2N HCl was added to leaf extract, providing lower buffering capacity of the barley leaves than corn leaves. After 2 hours of exposure to 10 ppm ${SO}_2$, the contents of ${SO}^{2-}_3$ and ${SO}^{2-}_4$ were increased in barley leaves, while only ${SO}^{2-}_4$ increased in corn leaves. After fumigation with 10ppm ${SO}_2$ for 2 hours, barley leaves showed significant decreases in activities of catalase, to 17% peroxidase, to 58%, and polyphenoloxidase, to 88%. Corn leaves showed increases in activities of peroxidase, to 136%, and polyphenoloxidase, to 128%. Absorption spectra of pigments obtained from ${SO}_2$-fumigated leaves were gradually decreased with the fumigation time increases, but the decrease was more significant in barley leaves. Fumigation with 50ppm ${SO}_2$ for 2 hours induced the greatest decomposition in carotenoid, followed by chlorophyll a and then chlorophyll b in barley leaves. The ratio of chlorophyll a/b was decreased from 4.1 to 3.6 in barley leaves, but in corn leaves it was maintained almost a constant level(4.9-4.8). The rate of decomposition of chlorophyll and carotenoid in corn leaves was very slow than those in the barley leaves. Fumigation with 50 ppm ${SO}_2$ for 2 hous, decreased the protein content of barley leaves to 59%, and that of corn leaves to 89%, and the extent of decrease in protein content was greater than that of pigments in barley and corn leaves. The rate of DCIP9dichlorophenol indophenol) photoreduction in ${SO}_2$-fumigated leaves was decreased to 18 and 67% in barley and corn leaves, respectively. However, DCIP photoreduction was considerably recovered about 32 and 92% with the addition of DPC(diphenylcarbazide) as an exogenous electron donor in barley and corn leaves, respectively.

  • 중작녹차를 효율적으로 이용하여 좋은 향미와 기능성을 가진 차를 만들기 위해 덖은 쌀보리에 중작녹차를 혼합하였다. 쌀보리녹차의 휘발성 향기성분의 추출은 Likens and Nickerson형 추출 장치를 사용한 동시증류추출방법에 의해 완수였으며, 그 농축된 추출물은 GC (Gas chromatography)와 GC-MS (Gas chromatography - mass spectrometry)에 의해 분석되었다. 3-methylbutanal, 2-methylbutanal, 그리고 2,5-dimethyl pyrazine 등의 화합물이 쌀보리로부터 분리, 동정되었다. 그리고 녹차에서는 ${\alpha}$-terpinolene, indole, ${\beta}$-ionone 등을 포함한 화합물을 분리, 동정하였으며, 또한 쌀보리와 녹차를 혼합한 쌀보리녹차에서는 2,5-dimethyl pyrazine, indole, 3-ethyl-2,5-dimethyl pyrazine 등을 포함한 화합물들이 분리, 동정되었다. 그 결과로부터 일반 중작녹차보다 볶은 쌀보리와 녹차를 혼합한 쌀보리녹차가 관능적으로 더 좋은 향미를 주는 요인으로 작용하는 것 같았다.
