Abstract: To obtain the water-soluble dietary fiber of corn,xylanase is used to degrade the seed coat of corn which is pretreated by amylase and protease.The components are analyzed by GC.The optimal enzymolysis conditions are: enzyme treating time 40min,xylanase concentration 1.0ml/g,temperature 45℃and pH 8.0.The soluble dietary fiber of corn consists of Xyl,Ara,Gal and Glu.

Key words: dietary fiber of corn, xylanase, lipase, amylase, protease
