| Abstract: | Optimum extracting conditions of pectin from pomelo peel which was used as raw material were investigated by single factor experiment, the influencing factors on the extraction rate of pectin from pomelo were the ratio of material to solvent, ultrasonic power, extraction temperature, and extraction time. Orthogonal test was designed on the base of signal factor experiment to optimum the extraction technology in this paper. The result showed that the optimum technological parameters were as follows：ratio of material to solvent was 1：15, ultrasonic power was 150 W, ultrasonic temperature was 80℃, ultrasonic time was 40 min. The extracting rate of pectin was 22.76%with the improved process. |
