Ultrasonic and slow freezing were used as intensification technology to extract water solube polysaccharide in plant material pumpkin. Through electronic microscope, changes of pumpkin cells could be observed: cell walls were folded significantly and some were broken with effects of ultrasonic; the majority of pumpkin cell walls were broken visibly with treatments of slow freezing due to formed ice crystals in plant cells. The results revealed that the application of ultrasonic and slow freezing could increase the extracting efficiency of water solube polysaccharide in fresh plant cells. Higher extracting efficiency could be achieved with slow freezing technology.
