Abstract

This study was performed to determine the best conditions for preparing Toranbyung. We examined different boiling periods (0~20 min) and types of Gomyeong (pine nut, soy, black sesame, and chestnut powder), as recorded in "Sumunsasul". The boiled taros were evaluated for proximate composition, free sugar contents, and Hunter's color values. In addition, the sensory characteristics of Toranbyung boiled for different periods and prepared using different types of Gomyeong were investigated. The moisture, protein, fat, and ash contents of taro decreased by 83.42~84.61%, 1.25~1.31%, 0.08~0.11%, and 0.62~0.81%, respectively, as the length of boiling time increased. Fructose, glucose, and sucrose, the major free sugars found in taro, decreased by 0.17~0.33%, 0.16~0.29%, and 0.26~0.38%, respectively, as the length of boiling time increased. Sensory evaluation indicated no significant difference in the flavor and taste of Toranbyung boiled for different periods of time. However, Toranbyung boiled for 10 min was significantly better and was found to be the most acceptable among all the samples. Furthermore, sensory evaluation of Toranbyung prepared with different types of Gomyeong indicated that the Toranbyung prepared with soy powder was favored over Toranbyung prepared using other types of Gomyeong. In conclusion, we determine that the best conditions for preparing Toranbyung were boiling for 10 min and using soy powder as the Gomyeong.

본 연구에서는 수문사설 에 수록된 토란병의 제조방법을 확립하기 위하여 토란의 가열 시간 및 고명에 따라 토란병을 제조하고, 품질특성을 비교 분석하였다. 가열 시간에 따른 수분, 조단백질, 조지방 및 조회분 함량은 각각 83.42~84.61%, 1.25~1.31%, 0.08~0.11%, 0.62~0.81% 범위로 조지방은 유의적인 차이가 없었으며, 조회분은 가열처리로 인해 유의적으로 감소하였다. 토란의 주요 유리당은 fructose, glucose 및 sucrose가 검출되었고, 가열 시간에 따라 각각 0.17~0.33%, 0.16~0.29% 및 0.26~0.38% 범위로 15분 가열처리 때까지 유의적으로 감소하였다. 경도 역시 가열 시간이 늘어날수록 2.75 kg에서 0.14 kg까지 감소하였다. 가열 시간에 따른 관능특성을 평가한 결과, 향과 맛은 각 처리구간 유의적인 차이를 보이지 않았고, 질감과 전반적인 기호도는 5분 처리구가 다른 처리구에 비해 유의적으로 낮게 평가되었으며, 10분 처리 이후에는 큰 차이를 보이지 않았다. 이상의 결과, 토란병의 제조 시 가열 시간은 10분이 바람직할 것으로 판단된다. 잣고물, 콩고물, 검은 깨고물 및 밤고물 등 고명 종류에 따른 토란병의 관능특성을 평가한 결과, 색, 향, 질감, 맛 및 전반적인 기호도는 각각 5.20~7.50, 5.40~7.70, 6.10~7.00, 6.10~7.20 및 6.20~7.60 범위로 평가되었고, 콩고물을 묻힌 토란병이 모든 항목에서 가장 높게 평가되었다.
