| Abstract: | Using biological methods,we extracted the glucan mannan from the Kanjac powders.The recovery rate of the product was 52.3% treated by enzymatic hydrolysis and sediment of Fehling's solution ;62.37% by enzymatic hydrolysis and sediment of ethanol and 60.5% by saccharolytic bacteria and sediment of ethanol.The purity of such glucan mannan product which was treated by ethanol sediment was about 90%. |
