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.
