Abstract

This study evaluated the quality characteristics of yukwa pellets and yukwa bases on the ratio of soju addition (0, 25, 50, 75, and 100% v/v). Yukwa base with 50% ratio of soju addition displayed the highest diameter, volume and specific volume. The yukwa base with 75% ratio of soju addition displayed the longest in length. The weight of yukwa base increased as the ratio of soju increased. Lightness increased in yukwa pellet and yukwa base as the ratio of soju increased. Lightness of yukwa base was higher than yukwa pellet, but yellowness and redness of yukwa base were lower than yukwa pellet. Air cell size of yukwa base decreased as the ratio of soju increased. The compression and cutting force of yukwa base with 50% ratio of soju addition were lowest, while yukwa base with 0% soju was highest. In the sensory evaluation, preference of color increased as the ratio of soju addition increased. Yukwa base with 50% ratio of soju addition was the highest in internal compactness, mouth-feel, and overall preference. The results show that a soju ratio of 50-75% addition for total liquid is useful in the production of high quality yukwa base.

불린 찹쌀과 콩에 소주 첨가비율을 0, 25, 50, 75 및 100% 비율로 첨가하여 제조한 유과반대기 및 유과바탕의 품질특성은 다음과 같다. 유과반대기의 두께, 길이, 무게, 부피 및 비용적은 시료 간에 유의한 차이가 없었다. 반면에 유과바탕의 경우 소주 50% 비율 첨가구는 직경, 부피 및 비용적이 가장 높았고, 소주 75% 비율 첨가구는 길이가 가장 길었으며, 무게는 소주 첨가비율이 높을수록 증가하였다. 유과반대기와 유과바탕의 색도는 L값의 경우 소주 첨가비율이 증가할수록 높았고, 유과바탕은 유과반대기에 비하여 L값은 높고 a와 b값은 낮은 경향을 나타냈다. 유과바탕의 형태는 소주 첨가비율이 증가할수록 일정하지 않았고, 소주 첨가비율이 증가할수록 유과바탕의 기공의 크기는 적었고, 기공 수는 많았다. 유과바탕의 압착력 및 전단력은 소주 50% 첨가비율이 가장 낮았고, 소주 무첨가구가 가장 높았다. 유과바탕의 관능검사 결과 향미와 맛에 대한 선호도는 시료 간에 유의한 차이가 없었다. 색에 대한 선호도는 소주 첨가비율이 증가할수록 높았고, 내부 치밀도, 입안에서의 느낌 및 전체적인 선호도는 소주 50% 비율 첨가구가 가장 높았다. 소주를 첨가하여 유과를 제조할 경우 유과바탕의 품질은 첨가된 총 액체량에 대하여 소주 첨가비율이 50-75%일 때 가장 높은 것으로 생각된다.
