This present study investigates the extraction characteristics and optimal parameters of the microwave-assisted extraction of pectin from waste mango peel (WMP). Microwave power, pH, time and solid-liquid ratio were selected as the extraction parameters and was studied by using Box-Behnken response surface design. The experimental data was analyzed by least square regression analysis method and a second order polynomial model was constructed for response from the experimental data. The constructed model was adequate to explain the relationships between independent variables and response. All studied factors had great influence on the yield, of pectin by individually and interactively. The optimum microwave assisted extraction conditions for the highest pectin yield (28.86%) from WMP was found to be: microwave power of 413 W, pH of 2.7, time of 134 s and solid-liquid ratio of 1:18 g/ml. The experimental value was well correlated with predicted value at the optimal condition. (C) 2014 Elsevier Ltd. All rights reserved.
