Abstract: For optimization of process for microwave-assisted extraction of pectin from wampee pulp, the effects of four factors including microwave power, extraction time, liquid-to-solid ratio and pH of extraction solution on pectin yield were researched using uniform design method. Model fitting and regression analysis of experimental data were made by SAS, and two significant factors which influence pectin yield, i.e. extraction time and liquid-to-solid ratio, were determined. The optimum process parameters of pectin extraction were obtained finally, of which the microwave powder was 600 W, extraction time was 8 min, liquid-to-solid ratio was 24:1mg/L and pH value of extraction solution was 2.0. Under these conditions, the experimental value of pectin yield was 3.59%, which was in close agreement with the predictive value of 3.65%. The quality of pectin extracted under optimum conditions was basically conform to the national standard by determination and analysis of basic characteristics of pectin. The results can provide a reference for industrialization of extraction of pectin from wampee.
