Abstract：In order to explore the mechanism of color formation in sugar-smoked chicken, it is necessary to extract pigment from sugar-smoked chicken skin. The objective of this study was to optimize process parameters for ultrasonic-assisted extraction of pigment from sugar-smoked chicken skin using one-factor-at-a-time method and response surface methodology (RSM). The absorbance of pigment was investigated with respect to three variables, ethanol concentration, ultrasonic time and solid-to-liquid ratio. The use of 85% ethanol as extraction solvent, a solid-to-liquid ratio of 10:1 (V/m) and ultrasonic treatment for 32 min were found to be the optimal conditions to obtain a higher absorbance value of 3.397, with only 0.38% deviation as compared to the predicted value. Hence, the optimized extraction process was feasible.
