This study was conducted to determine the optimal steeping period and temperature for Gangjung production, using response surface methodology based on the previously reported sensory characteristics. Five sensory attributes ('degree of expansion', 'sourness', 'butyric acid flavor', 'hardness' and 'degree of melting'), which showed high variability explained (R²) and recognized to be important for the quality of Gangjung were selected for optimization. As a result, the optimal steeping temperature and period of waxy rice were determined to be 31.5℃ and 9 days, respectively.
