Chinese Abstract

以新鮮南瓜為研究對象,用超聲波和緩凍2種方法強化提取水溶性多糖。電子顯微鏡顯示,植物細胞壁在超聲波作用下產生了明顯的褶皺,一些細胞破裂;植物細胞經過緩凍處理後,由於植物細胞內形成了晶粒較大的冰晶,從而使大部分植物細胞產生破碎作用。超聲波和緩凍2種方法都能強化植物性多糖的提取,緩凍的效果優於超聲波。

English Abstract

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.
