Abstract: Konjac glucomannan was enzymolysized by cellulase (Ec.3.2.1.4).The optimal parameters were 10 g konjac refined powder were reacted with 500 U cellulase at pH  5.0 and in 40 ℃ for 2 h.The molecular weight of the oligo-glucomannan was measured by GPC,the mean Mw was 5 100 and the mean Mn was 7 610.

Key words: Amorphophallus konjac;konjac glucomannan;oligo-glucomannan, cellulase
