Abstract

Jeungpyun was prepared with varying degrees of fermentation, and their effects on its quality characteristics were examined. In height and volume of jeungpyun, the samples treated with a first fermentation time of 240 minutes, and second and third fermentation times of 60 and 30 minutes, respectively (Sample E) had the best fermentation quality. A texture profile analysis, Hunter's color and sensory evaluation of these jeungpyun were carried out during the 4 days of storage. In the texture profile analysis, the hardness was observed to reduce in proportion to decreases in the fermentation time. The lightness value of Sample E showed one of the highest among the samples, but decreased as the storage time was prolonged. The results of the sensory evaluation showed that Jeungpyun of Sample E had higher swell, softness and moisture scores.

발효시간에 따른 증편의 기계적, 관능적 품질특성을 저장기간 동안 평가하였다. 증편의 높이와 부피는 1차 발효 240분, 2차 발효 60분, 3차 발효 30분을 한 E 시료가 가장 높아 발효가 잘 된 것으로 나타났고 물성특성의 경우 전통적으로 제조한 시료보다 발효시간을 단축시킨 시료들이 유의적으로 견고성이 낮았고 저장기간의 증가에 따라 그 값이 증가하여 증편이 단단하게 경화되는 것으로 나타났다. 기계적 색도의 경우 명도는 E 시료가 가장 높았으며 저장에 따라 감소하는 것으로 나타났다. 관능적 품질의 경우 부풀기의 정도, 부드러운 정도, 촉촉한 정도는 E 시료가 가장 높게 나왔다. 증편의 높이, 부피, 명도, 부풀기의 정도, 부드러운 정도, 촉촉한 정도에서 가장 높은 수치를 나타낸 E 시료가 가장 바람직한 것으로 나타났다.
