The principal objective of this study was to determine the optimal mixing ratios of three different quantities of spirulina, salt and water for the preparation of Korean rice cake (Dukbokiduk) via response surface methodology on the basis of color, texture, and sensory test. The spirulina levels were tested in a range of $1{\sim}3%$, the water levels in a range of $15{\sim}25%$, and salt levels were tested a range of $0.5{\sim}1%$ by weight of rice powder. Taste was influenced most profoundly by the amount of added spirulina. Optimal taste was achieved with 1% of spirulina, 0.75% of salt and 20% water. Thus, the optimal mixing ratios of spirulina, salt, and water for Dukbokiduk were 1.0%, 0.57%, and 19.46%, respectively.
