| Abstract: | This paper was to study the process of extracting polysaccharide from Zizyphus jujuba Mill. waste by basic extraction and discoloration. The best conditions were selected by orthogonal design with polysaccharides yield, content and discoloration ratio as index. The optimm basic extraction procedure was as following: Zizyphus jujuba Mill. waste was extracted with 20 times of 0.5mol/L Na 2CO 3 solution at 80℃ for 3h. The optimum discoloration procedure was to add 2% active carbon to polysaccharide solution at 40℃, pH 3.5 and stri for 20 min. |
