AB  - Porang is a potential source of glucomannan. This research objective was to find 
      a direct glucomannan isolation method from fresh porang corm to produce high 
      purity glucomannan. Two isolation methods were performed. In first method, sample 
      was water dissolved using Al(2)(SO(4))(3) as flocculant for 15 (AA15) or 30 
      (AA30) minutes with purification. In second method, sample was repeatedly milled 
      using ethanol as solvent and filtered for 5 (EtOH5) or 7 (EtOH7) times without 
      purification. The characteristics of obtained glucomannan were compared to those 
      of commercial porang flour (CPF) and purified konjac glucomannan (PKG). High 
      purity (90.98%), viscosity (27,940 cps) and transparency (57.74%) of amorphous 
      glucomannan were isolated by EtOH7. Ash and protein level significantly reduced 
      to 0.57% and 0.31%, respectively, with no starch content. Water holding capacity 
      (WHC) of EtOH7 glucomannan significantly enhanced, whereas its solubility was 
      lower than those of PKG due to its ungrounded native granular form.
