Abstract

This study was carried out to investigate the quality characteristics of Jeung-Pyun with respect to the addition ratio of pigmented rice and fermentation method. As the mont of pigmented rice was increased, the moisture content of the products added with yeast tended to increase more than those made in the traditional way. Regardless of fermentation method, L value and b value of Jeung-Pyun without pigmented rice were higher than those of Jeung-Pyun with pigmented rice, for which the values were significantly low. The samples with 5% or 10% pigmented rice had a high degree of expansion. The other samples showed no visible difference. The hardness, cohesiveness, springiness and chewiness tended to decrease. On the other hand, the adhesiveness was increased. In both fermentation methods, as the amount of pigmented rice was increased, the gelatinization degree was raised. In sensory evaluation, the characteristics of Jeung-Pyun with 30% pigmented rice were very poor, except for the characteristics on pore uniformity. The other samples and both fermentation methods were hardly different.

발효방법과 유색미 첨가량을 달리한 증편을 제조하여 품질특성을 검토하였다. 유색미 첨가량이 많을 수록 yeast를 첨가한 증편의 수분함량이 증가하였으며, 전통적인 방법으로 제조한 증편보다 대체로 높은 수분함량을 나타내었다. L값과 b값은 발효방법에 관계없이 유색미를 첨가하지 않은 시료가 첨가한 시료에 비해 높았으며, a값은 낮았다. 유색미를 5% 또는 10% 첨가한 시료의 팽화도가 유의적으로 높았으며 다른 시료들간에 유의차가 없었다. 유색미 첨가량이 많을수록 경도, 응집성, 탄력성, 씸힘성은 감소하는 경향이었으나, 부착성은 증가하는 경향이었다. 호화도는 발효방법에 상관없이 유색미 첨가량이 많아질수록 유의적으로 높았다. 관능검사 결과 유색미를 30% 첨가증편이 기공의 균일성 항목을 제외하고 가장 좋지 않게 평가되었으며, 나머지 시료사이에는 유의적인 차이가 거의 나타나지 않았다. 전통적인 방법과 yeast를 첨가사이에서는 뚜렷한 차이는 보이지 않았다.
