| Abstract: | To optimize the decolorization technology of polysaccharide from Asparagus.The experiment was carried out by asparagus polysaccharide activated carbon decolorizing method,on the basis of single factor test conducted uniform design,the integrated adsorption effect index was inspected.Using the orthogonal design,conditions were optimized as follows：temperature 80 ℃,time 30 min,amount of active carbon 25 g/L and pH= 6.5.Under this condition,the integrated absorption index,decolorization rate,deprotein rate and recovery rate of polysaccharide were 68.24%,67%,89% and 56%,respectively. |
