Abstract

This study investigated the effect of bamboo leaf powder, added at content of 0%, 3%, 6%, 9% and 12%, on the quality and sensory characteristics of rice cake imprinted with flower pattern (Ed-there is no respecitive comparison here) The chemical composition as a whole was 3.07${\pm}$0.12% of moisture, 5.87${\pm}$0.02% of crude protein, 2.52${\pm}$0.05% of crude fat, 23.70${\pm}$0.07% of crude fiber and 7.73${\pm}$0.02% of crude ash. With increasing amount of added bamboo leaf powder, the hardness and chewiness of the cake were significantly increased(p<0.05), while the cohesiveness, springiness and adhesiveness were decreased. In chromaticity, the L-value, the indicator of brightness, was significantly decreased with increasing bamboo leaf powder content. The a-value, the indicator of redness, was significantly lower than the chlorophyll color (p<0.05). The b-value, the indicator of yellowness, was increased indirect proportion to the content. In sensory test, the sensory characteristics such as color, flavor, taste and chewiness were all stronger with increasing powder content, whereas the softness and dampness were weaker. The greatest overall satisfaction was achieved by the sample group of cake with 6% preference added powder.

댓잎 분말 첨가량(0%, 3.0%, 6.0%, 9.0%, 12.0%)을 달리하여 제조한 댓잎 절편의 품질특성과 관능적 품질특성을 평가하였다. 일반성분은 수분함량은 3.07${\pm}$0.12%, 조단백질 5.87${\pm}$0.02%, 조지방 2.52${\pm}$0.05%, 조 섬유 23.70${\pm}$0.07%, 조회분 7.73${\pm}$0.02%로 나타났다. 물성측정에서 견고성과 씹힘성은 댓잎분말 첨가량이 많을수록 증가하여 유의적으로 차이가 있었고(p<0.05), 응집성, 탄력성, 부착성은 댓잎 첨가량이 많을수록 감소하는 경향을 보였다. 색도에서 L값은 절편 제조시 첨가한 댓잎 분말 양이 많을수록 유의적으로 감소하였고, 적색도를 나타내는 a값의 경우 음의 값으로 녹색을 나타내었고 각 첨가군에서 유의적인 차이를 보였다(P<0.05). 한편 황색도를 나타내는 b값의 경우 대조구의 경우 1.42로 가장 낮게 나타났고, 6% 댓잎 절편이 가장 높은 값을 보였다. 관능적 특성검사는 색, 향, 맛, 씹힘성에서 모두 댓잎양이 많을수록 특성 강도를 강하다고 평가하였고, 부드러움, 촉촉함은 반대로 평가되었다. 전반적인 기호도는 6.0% 첨가군이 가장 높은 것으로 나타났다. 따라서 절편에 댓잎 분말을 사용함으로써 댓잎의 약리성분과 더불어 섬유소의 섭취로 여러 건강적 이점으로 건강 기능성 상품개발이 가능할 것으로 예상된다. 앞으로 댓잎을 이용한 색소개발과 많은 가공식품에 적용, 신제품 개발 등 다양한 연구가 행해져야 할 것이다.
