Abstract

Cholpyon, a traditional Korean rice cake, was prepared using pigmented rice and the quality characteristics them were compared with Cholpyon made of brown and white ice during 24 hr storage at 20$\^{C}$. In proximate composition, crude protein contents were not significantly different among three rice varieties whereas the contents of crude lipid and ash in pigmented and brown rice were higher than that of white rice. In mechanical characteristics, 100% pigmented rice Cholpyon showed lower values for hardness, cohesiveness, springiness and chewiness, and higher value far adhesiveness compared with those of white rice Cholpyon. These results were maintained for 24 hours. Sensory Characteristics of 100% pigmented rice Cholpyon such as color, hardness and overall quality were better than those of white rice Cholpyon. Brown rice Cholpyon had similar mechanical properties to 100% pigmented rice Cholpyon, but showed the lowest preference in color.

유색미(수원415)로 제조한 절편의 저장기간에 따른 품질 특성 변화를 현미 및 일반미로 제조한 절편과 비교하였다. 유색미, 현미 및 백미의 일반성분 분석 결과, 조단백의 함량은 유사하였으나 조지방과 조회분 함량은 유색미와 현미가 백미와 비교하여 높게 나타났다. 기계적 조직감에 있어서, 100% 유색미떡은 백미떡과 비교하여 경도가 낮아 부드러운 조직감을 보였으며 24시간 저장 후에도 유사한 결과를 보여 노화가 지연됨을 알 수 있었다. 응집성, 탄력성 및 씹힘성 등도 백미떡과 비교하여 낮았으나 부착성은 높은 것으로 나타났다. 50% 유색미떡은 100% 유색미떡에는 미치지 못하지만 백미떡과 비교하여서는 경도가 낮았다. 현미떡은 백미떡과 비교하여 부착성에는 차이가 없으나 경도, 응집성, 탄력성 및 씹힘성의 경우는 100% 유색미떡과 유사한 결과를 보였다. 관능검사 결과, 100% 유색미떡은 색, 경도 및 종합적 기호도 등이 우수하게 평가되었다. 반면, 현미떡은 백미떡과 비교하여 경도는 좋으나, 색에 대한 기호도가 백미, 50% 및 100% 유색미떡과 비교하여 낮은 것으로 나타났다. 결론적으로, 100% 유색미 절편이 백미 및 현미 절편과 비교하여 기계적 및 관능적 품질특성이 좋은 것으로 나타났다.
