This study was performed to provide basic data that will predict the usefulness of buckwheat sprout as food materials. The quality characteristics of noodles prepared with buckwheat sprout powder were investigated The buckwheat sprout powder was added to the noodles in 0, 2, 4, 6, and $8\%$ in proportion to the weight of wheat flour, respectively. The added amounts of buckwheat sprout powder did not affect the volume of the noodles. The weight of noodles was decreased, whereas tumidity of the soup after cooking the noodles was increased with the increment of the amount of added buckwheat sprout powder. The color of powder mixture, wet noodles, and cooked noodles was changed by the addition of buckwheat sprout powder. Lightness(L) was decreased, whereas yellowness(b) and redness(a) increased as the amount of buckwheat sprout powder increased. In the texture analysis, hardness and chewiness of wet noodles were increased significantly by the addition of buckwheat sprout powder. Hardness, chewiness, and gumminess increased significantly in the cooked noodles with more than $6\%$ substitution of buckwheat sprout powder. Other textural properties did not show any significant changes. The results of sensory evaluation revealed that the overall preference of noodles with 2 to $4\%$ substitution of buckwheat sprout powder was better than other sample groups. Therefore, the appropriate amount of addition for the buckwheat sprout noodles was 2 to $4\%$ buckwheat sprout powder in proportion to the weight of wheat flour.

This study was conducted to determine the usefulness of bamboo leaf powder as a functional ingredient for buckwheat cold noodles. The anti oxidative and fibrinolytic activities of bamboo leaf powder were very high, and were further maintained or improved after strong heat treatment. We prepared buckwheat cold noodles using 0%, 3% or 5% of bamboo leaf powder. Only the cohesiveness of the noodle having 5% bamboo leaf powder was lower than that of the noodles contained 0% and 3% bamboo leaf powder. The L-, a- and b-values were significantly different between noodles which contained bamboo leaf powder and those which did not. Nevertheless, the amount of bamboo leaf powder didn't affect the color parameters of buckwheat cold noodles. According to sensory evaluation, the addition of bamboo leaf powder improved the score of color and texture of buckwheat cold noodles, but overall acceptance was not significantly affected. Cooked volume, cooking loss and turbidity of buckwheat cold noodle containing 5% bamboo leaf powder were lower than the others, indicating that adding 5% bamboo leaf powder prevented the softening of the noodles with moist heat. We concluded that the application of bamboo leaf for the production of buckwheat cold noodle will be a good way to intake the biologically active ingredients for good health.

메밀가루의 첨가량(0, 10, 20, 30, 40)을 다르게 제조한 옐로우 레이어 케이크의 품질 특성을 조사하였다. 반죽의 비중은 메밀가루 첨가량이 증가할수록 증가하였다. 케이크 단면의 색도는 메밀가루 첨가량이 증가함에 따라 L값과 b값(황색도)은 낮았으나, a값(적색도)은 증가하였다. 케이크 부피는 메밀가루 첨가량이 많을수록 부피가 작아지는 경향이었다. 케이크 대칭성 및 균일성지수는 대조구와 비교하여 유의적인 차이가 없었으나, 굽기손실률은 메밀가루 첨가 시 다소 낮게 나타났다. 경도는 대조구 보다 메밀가루 첨가량이 증가할수록 유의적으로 높게 나타났다. 관능검사에서 맛은 메밀가루 20% 첨가 시 높은 점수를 얻었으며, 조직감과 종합적기호는 메밀가루 20% 첨가 시까지는 대조구와 유의적 차이가 없었다. 따라서, 밀가루의 일부를 메밀가루로 대체하여 옐로우레이어케이크를 제조하는 경우에는 메밀가루 20% 수준 첨가 시 케이크의 품질이나 기호적 특성이 향상된 제품으로 제조 가능할 것으로 기대된다.

Various amounts of buckwheat powder (0%, 1%, 2%, and 3%) were added to emulsion-type pork sausages. The effects of buckwheat powder on the physicochemical characteristics of the emulsion type sausages, including proximate composition, cooking yield, viscosity, pH, instrumental color, texture profile analysis (TPA), and sensory evaluation, were determined. Increased levels of added buckwheat powder led to higher moisture (p<0.05), ash content (p<0.05 or >0.05), and cooking yield (p<0.05). However, the protein and fat contents of the sausage samples were lower (p<0.05) with higher levels of added buckwheat powder. The instrumental color and pH values were affected by the addition of buckwheat powder, which has a pH of 6.1 and associated color coordinates of $L^*=75.0$, $a^*=1.3$, and $b^*=8.7$. Meat batter with 3% buckwheat powder was shown the highest (p<0.05) viscosity indicating great formation of emulsion. There were no significant differences in the TPA among the treated samples. The viscosity value increased with increasing cooking yield in the batter ($r^2=0.7283$) i.e. the correlation coefficient between the two measurements was very high and positive. For sensory traits except for tenderness, the highest scores (p<0.05) was detected on sausages with 3% added buckwheat powder by a panel. These results suggest that the addition of 3% buckwheat powder to emulsion-type sausages produces a more beneficial meat product, with a lower fat content, greater formation of emulsion and no adverse effects on sensory properties.

Muffins are prepared with different amounts of buckwheat powder (0~50%), and their quality characteristics are being investigated. The specific gravity is not affected by the addition of buckwheat powder (10~30%). The lightness (L value) and yellowness (b value) of muffins are decreased with increasing buckwheat amounts, whereas redness (a value) increased. No significant differences are being observed between muffins added with buckwheat (0~50%) for volume, weight, height, baking loss rate and specific volume. For textural characteristics, the cohesiveness, springiness and gumminess of muffins showed no significant differences between the groups, whereas hardness was decreased. In the sensory evaluation, score of color is decreased with increasing buckwheat amounts, whereas grain, flavor, taste, texture and overall acceptances are insignificant between groups. Upon the results of this study, it is assumed that the developments of food products when using buckwheat are prospective in response to health-oriented consumers.

This study was tried to evaluate possibilities for discriminating the mixture degree of wheat flour from buckwheat products. Buckwheat was milled into four grades of powder, i.e. whole grain flour (WGF), inner layer flour(ILF), middle layer flour(MLF) and outer layer flour(OLF)), and these powders were mixed with wheat flour(WF) to make mixed samples. Ash, protein and fat contents of the buckwheat flours were high in the order of OLF=WGF>MLF>ILF. On the other hand, WF showed a similar content to OLF in ash and protein, and to ILF in fats. Potassium and magnesium contents were higher in all the buckwheat powder than in the wheat flour. Flavonoid contents were higher in order of OLF>WGF=MLF> ILF, but it was not in wheat flour. Although the reliable correlation between mix ratio and components, i.e. mag nesium or ash analyzed were found, it did not seem to reflect sufficiently the expected variations of contents of original material components. Also, compositions of commercial buckwheat products were analyzed to evaluate the mixed ratio of buckwheat flour and wheat flour. The results suggest that the components analyzed in this study as putative marker were not good in determining whether or how much buckwheat products contained wheat flour.

The purpose of this study was to investigate the properties of frozen cookies containing buckwheat flour. Buckwheat flour was added to cake flour bases at concentrations of 3%, 6%, and 9%. Falling numbers, RVA (rapid visco analyzer) increased with the addition of buckwheat flour, whereas initial pasting temperature decreased. The set back value, which is a prediction of retrogradation, did not show any significant difference. The alveographic P values of the treatment were lower than that of the Control. In the farinogram test, water absorption increased upon the addition of buckwheat flour, whereas stability and farinogram quality number decreased. In conclusion, the addition of 6% buckwheat flour is recommended to obtain the optimal volume of frozen cookies.
