Abstract: Duffau distillation method for pentosans assay in waste water of wheat glutenin processing was studied. The results indicated that the reproducibility and percent recovery of Duffau distillation method all meet the requisition of analytical experimentation, and the analytical results are accurate. The contents of waste water pentosans in wheat glutenin processing are between 0.1938~0.2939g/100ml.

Key words: pentosans, Duffau distillation method, waste water of wheat glutenin
