                                                                                  Introduction to konjac 

         Konjac is categorized in the aroideae, belongs to the perennial plant and is mainly produced in Sichuan and Yunnan provinces.

Main ingredients

       The main ingredients of konjac are glucomannan (KGM), which is a kind of high molecular polysaccharide with molecular weight of 200,000 -2 million and its chemical structure is a kind of polymer heteropoly sugar made from 1:1.6-1.7 glucose and mannose residues and polymerized through -1,4 glucosidic bond.

                                                                  Introduction to glucomannan (KGM)

Water solubility

      KGM is soluble in water and its dissolution rate increases with the decrease of granularity of konjac flour.

Gelling property

     Compared with carrageenan, guar gum, xanthan gum and gelatin etc., KGM has its unique gelling property. The first is its higher viscosity; the second is that it can form thermal reversible and thermal irreversible gel under certain circumstances.  .


     KGM is a kind of vegetable gelatin and has a better stability compared to xanthan gum, guar gum and locust bean gum. It can remain its stability without precipitation under room temperature and the condition of below PH3.3.
