영어초록

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℃ 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.
