In the study, we determined the optimal ingredient mixing ratio for the preparation of sponge cake containing bamboo (Pseudosasa japonica Makino) leaves. This experiment was designed in according with the D-optimal design of mixture design, which involved 14 experimental points including 4 replicates for three independent variables (sugar 110${\sim}$129%, bamboo leaves 3${\sim}$8%, oil 10${\sim}$25%). The results the F-test, specific gravity, volume and color values (L, a, b) decided a linear model, while the viscosity, hardness and sensory characteristics (color, smell, taste, texture and overall acceptance) decided a quadratic model. The results of our fitness analysis demonstrated that in all characteristic, the probabilities were significant within 0.05%; thus, the models were accepted as appropriate. The response surface and trace plot results demonstrated that increasing amounts of added bamboo leaves induced a reduction in brightness, and increasing redness and yellowness. In addition, increasing amounts of bamboo leaves caused increases in hardness, and thus the softness of the cake decreased. And as the level of added oil increased, softness increased. Cake samples received low sensory evaluation scores when sugar, bamboo leaves, and oil were added above their optimal levels. In the numeric optimization, the optimal ingredient amounts were 121.36% sugar, 4.96% bamboo leaves, and 15.69% oil. The above results demonstrate the feasibility of adding bamboo leaves to sponge cake, and therefore, a bamboo leaves as a functional food.

대잎 분말 첨가량에 따른 콩다식의 수분 함량, 색도, 품질특성 및 관능적 특성을 살펴보고자 한다. 수분 함량은 24.39~26.29%이며, 색도는 L값, a값, b값 모두 대잎 분말 첨가량이 증가할수록 감소하는 경향을 보였다. 조직감 측정시 경도, 검성, 씹힘성은 대잎 분말 첨가량이 증가할수록 증가하는 경향을 보였으나, 부착성은 감소하는 경향을 보였다. 관능 평가시에는 대잎 분말의 특성에 의해 맛, 색, 향, 전체적인 기호면에서 대잎 분말 6%를 첨가한 다식이 가장 좋게 평가되었다.
