  • 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.

  • This study examined the quality characteristics and anti-oral microbial activity of bamboo leaf jelly prepared with different 5 levels (0, 10, 20, 30, and 40%) of bamboo (Phyllostachys nigra var. henonis) leaf extract. The sugar contents of bamboo leaf jelly were increased significantly by increasing the level of bamboo leaf extract. The luminance and Hunter's a values of the jelly samples increased with increasing bamboo leaf extract, but the 40% bamboo leaf jelly had the lowest Hunter's b values. The hardness, adhesiveness, gumminess, and chewiness increased significantly with increasing bamboo leaf extract. Among the mechanical properties, only the flavor of the jelly with 30 and 40% bamboo leaf extract were increased significantly. The extract of bamboo leaves had strong antimicrobial activity against S. mutans, S. sobriuns, P. gingivalis, and P. intermedia at a concentration of 40%. These results suggest that bamboo leaf extract can be useful in the production of high quality jelly.

  • The purpose of this study was to investigate the rheological characteristics of medium wheat flour mixed with bamboo leaf and lotus leaf powders. Rheological properties of the mixed flours were tested based on falling number, color, RVA, farinogram, and rheofermentometer analyses. Falling numbers increased with addition of bamboo leaf and lotus leaf powders. The L values of all mixed flours were less than that of control. The 1% mixed flour sample containing bamboo leaf and lotus leaf powders was not significantly different from 3% mixed flour. The a values of the mixed flour decreased as bamboo and lotus powders increased, whereas b values increased. Addition of bamboo leaf and lotus leaf powders to flour reduced peak viscosity, holding strength, and final viscosity. The set back values of mixed wheat flour containing bamboo leaf powder were lower than those of mixed wheat flour containing lotus leaf powder, suggesting that bamboo leaf powder suppressed retrogradation of flour compared to lotus leaf powder. In the farinogram, the water absorption and consistency of the flours containing bamboo and lotus leaf powders increased, whereas development time and stability decreased. The fermentation time of dough with lotus leaf powder was less than that of dough with bamboo leaf powder.

  • Bamboo leaf powder was added to Jeolpyun to increase the neutraceutical effects and storage period. The bamboo leaf powder was added to rice flour at ratios of 0, 4, 6, 8, and 10% (w/w), and they were treated with aqueous malt extract to extend storage. The Jeolpyun was stored at $20^{\circ}C$ for 72 hr, and the physical and sensory characteristics were evaluated. As a result, the crude fat, crude protein, moisture, crude ash and total dietary fiber contents in bamboo leaf powder were 4.36, 11.29, 3.37, 7.33, and 65.57%, respectively. The Hunters L, a, and b values decreased significantly as the amount of bamboo leaf powder increased; however, the a and b values increased during storage. The paste property setback values decreased with the malt extract treatment and with increasing amounts of bamboo leaf powder. In a sensory analysis, hard texture strength in the malt extract and bamboo leaf powder treatment groups was less than that in the control during storage. The Jeolpyun prepared with malt extract and no bamboo leaf powder was the most accepted by consumers. Although adding bamboo leaf powder resulted in less consumer acceptance except for the flavor attribute, adding 4% and 8% bamboo leaf powder resulted in better consumer acceptance for texture, taste, and overall acceptance than that of the control. In a microbial analysis, adding bamboo leaf powder resulted in fewer mold colonies. In conclusion, adding 4% bamboo leaf powder and malt extract to Jeolpyun improved its storage properties.

  • The objective of this study was to assess the quality characteristics of morning-rolls containing various levels (0, 4, 8, and 12%) of bamboo leaf powder. The results demonstrated that morning-roll volume decreased with increasing amounts of bamboo leaf powder, and as the bamboo leaf powder content increased, the Hunter's color 'L', 'a' and 'b' values were significantly reduced (p<0.05). For the amylogram characteristics, the addition of bamboo leaf powder to the flour reduced peak viscosity, holding strength, final viscosity, and setback. The results of the sensory evaluation demonstrated that control (0%) and 8% addition of bamboo leaf powder had the best scores in taste, color, flavor, texture, appearance, softness, wetness, residual mouth feel, and overall acceptability. Thus, it appears that by using 8% additions of bamboo leaf powder, the functionality, nutritional composition, taste, color, and flavor of morning-rolls containing bamboo leaf powder can be developed. This result will support the development of better quality bamboo-leaf morning-rolls.

  • Bamboo leaf powder was added to Chiffon cake to increase its neutraceutical effects and storage periods. Specifically, 0, 7, 10 and 13% leaf powder was added to the cakes. The content of total dietary fiber in the bamboo leaf powder was 65.57%. The moisture content did not differ significantly among groups. The cake containing 10% bamboo leaf powder had the greatest volume, whereas the control group (0% bamboo leaf powder) had the lowest volume (p<0.05). The Hunter's L and a values decreased significantly as the amount of bamboo leaf powder increased. The b value of the control was lowest among the groups (p<0.05). Evaluation of the consumer acceptance of flavor revealed that the cakes containing the added bamboo leaf had greater consumer acceptance than the control. However, when the color was evaluated, the 13% group showed the lowest acceptance (p<0.05). Other factors such as texture, taste and overall acceptance did not differ significantly among groups. Additionally, the elasticity did not differ among groups, while the air cells were most uniform in the control. The strength of bamboo leaf aroma, bitter taste and aftertaste increased as the amount of bamboo leaf powder added increased. Cakes containing 10% and 13% added powder had the greatest moisture content, while the control had the lowest content (p<0.05). As in previous studies, the results of this study indicated that 10% bamboo leaf powder was the optimal level for the preparation of Chiffon cake. To evaluate the storage of cakes, the 10% group and the control were inoculated with Aspergillus oryzae and then incubated at $30^{\circ}C$ for 6 days. The microbial colony counts in the control group were dramatically increased after 48 hrs; however, the fungal concentration of the 10% group did not increase for 4 days. In conclusion, the addition of 10% bamboo leaf powder to Chiffon cake increased the storage time while maintaining adequate consumer acceptance.

  • 대잎 분말 첨가 설기떡의 관능적 특성과 기계적 특성, 수분 함량과 색도를 측정하였다. 대잎분말의 첨가량은 0%인 대조군을 BP0으로 하였으며, 1% 첨가군을 BP1, 2% 첨가군을 BP2, 3% 첨가군을 BP3, 4% 첨가군을 BP4로 표기하였다. Textureanalyzer 분석 결과를 살펴보면 설기떡에 대잎 분말 첨가량을 증가하면 할수록 견고도가 증가하고, 부착성과 점착성, 씹힘성, 응집성도 첨가량이 증가함에 따라 증가되는 결과가 나타났다. 그러나 탄력성은 다른 처리구와 다르게 유의적으로 차이가 없었다. 수분 함량은 대잎 첨가 설기떡의 경우 37~39%를 유지하였으며, 색도는 대잎 분말의 첨가 수준이 증가될수록 L값은 감소되며 a, b값은 증가 되는 경향이었다. 관능평가 결과는 색과 촉촉한 정도에서 BF3가 가장 높게 평가되었다. 이러한 연구 결과로 BF3의 첨가구가 가장 바람직한 첨가 비율임을 알 수 있었다. 따라서 맛과 기능적인 면에 대한 것도 기대를 걸어보며, 앞으로 후속 연구가 더 많이 나오기를 기대한다.
