Abstract: The method of hot air convection drying was applied to extract Konjac flou r fromfresh Konjac.The content andcomponentofKonjac Glucomanna(KGM)was determinedby purification.The result was 70%KGMwithintrinsic viscosity 26.3Pa.S.After being formented at temperature 37℃for 72h the Bifidus growthfactor(monosaccharide and tetrasaccharides)was determinded by thinlayer chroma togramto showthe dramatical increase of Bifidobacterium.

Key words: Konjac glucomanna , Holoside , Bifidus growth factor
