Abstract

The sensory properties and flavor components of the white bread added with arrowroot juice. The lightness of bread crumb decreased significantly as arrowroot juice was added. While the yellowness increased slightly, redness increased remarkably. The hardness, chewiness and adhesiveness of the white bread added with arrowroot juice increased more than those of the control bread, but they had no statistical significance. While the gumminess increased significantly and springiness decreased significantly, the cohesiveness did not indicate significant differences among the comparison groups. In sensory evaluation, the texture, flavor and sweetness did not indicate significant difference among the comparison groups, while the color and overall acceptability indicated significant difference. The optimum concentration of arrowroot juice in the white bread was 25% based on the sensory evaluation scores. The main flavors components of the white bread added with 25% arrowroot juice were compounds translated by arrowroot juice and the compounds formed by amino-carbonyl reaction. The translated flavors were methoxy phenol, ${\beta}-damascenone$, benzylcyanide, and menthofuran. The compounds formed by amino-carbonyl reaction were alkyl pyrazines, pyrroles and furans.

칡즙 첨가 식빵의 관능적 특성은 색도, 조직감, 관능평가를 통해 조사하였다. 첨가된 칡즙의 양이 증가할수록, L값은 유의적으로 현저히 감소하였고, b값은 유의적인 증가를 나타냈으며 a값은 유의적으로 현저한 증가를 나타내었다. 경도, 씹힘성과 부착성은 유의성은 없으나 증가한 반면 껌성질은 유의적인 증가를 보였고, 탄력성과 응집성은 유의적으로 감소하는 경향을 나타내었다. 칡즙 첨가 식빵의 관능평가 결과로 칡즙이 25% 첨가되었을 때, 최적의 배합 비율로 평가되었다. 조직감에 대한 기호도는 칡즙의 양이 증가할수록 식빵이 쫄깃쫄깃한 성질이 증가하나 입안에 붙는 듯한 느낌을 주어 15% 첨가 군에서 가장 높게 나타났다. 단맛에 대해서는 식빵의 종류나 관능검사를 실시한 사람들의 연령에 관계없이 유의적인 차이가 거의 없었다. 냄새에 대한 관능검사 결과는 식빵을 먹었을 때, 첨가된 칡즙의 양이 증가할수록 유의적으로 높게 나타났다. 칡즙과 칡즙이 25% 첨가된 식빵의 향기성분 농축물을 GC-MS로서 분리 동정하고, 칡즙의 특징적인 향기 화합물이 칡즙 첨가 식빵의 향기 화합물로 전이된 향기성분을 고찰하였다. 칡즙의 향기 화합물의 특징적인 것으로는 미생물 발효차에서 동정된 methoxy phenol 화합물들, 3-methoxy acetophenone, 녹차 등에서 동정된 ${\beta}-damascenone$, 반 발효차인 오룡차와 포종차에서 동정된 꽃 향기 성분인 benzylcyanide, 그 외 menthofuran과 coumarin 등 총 35종이 동정되었다. 칡즙 첨가 식빵의 향기 화합물은 굽기 과정의 갈변반응에 의해 생성된 구수한 향에 기여하는 pyrazine류, pyrrole류, pyridine류 20종이 동정되었고, 아울러 칡즙 첨가에 의해 전이된 methoxy phenol화합물과 benzylcyanide, ${\beta}-damascenone$, menthofuran과 coumarin 등의 총 55종이 동정되었다.
