| Abstract: | Extracting pectin from orange peel with ultrasonic-assistant solvent method was studied,hydrochloric as solvent and ethanol as precipitator.The influencing factors including temperature,liquid-to-solid ratio,pH value of the solution and extracting duration are studied.The optimal process conditions were obtained by orthogonal analysis as follows:pH value 2.0,temperature 70 ℃,extracting duration 30min,the liquid-to-solid ratio was 40 mL/g，and at the condition the extracting rate of pectin was 13.9%. |
