Abstract
The present invention relates to a process for reducing the viscosity of a plant material, which process comprises treating the plant material with a xylanase having i) a WSPS per mg protein added which is higher than 0,06, and/or ii) a WSPU per mg protein added which is higher than 15, and/or iii) a specific activity of more than 0,053 FVRU/mg protein. Further, the invention relates to use of a xylanase preparation for separating a plant material, such as wheat, into separate useful components as well as processes for such viscosity reduction or separation.
