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.
La présente invention concerne un procédé pour réduire la viscosité d'un matériau végétal. Ce procédé consiste à traiter le matériau végétal par du xylanase, comportant i) une unité de pentosane par mg de protéine ajoutée supérieure à 0,06 et/ou ii) une unité de pentosane par mg de protéine ajoutée supérieure à 15, et/ou iii) une activité spécifique de plus de 0,053 unité relative de viscosité/mg de protéine. En outre, l'invention concerne l'utilisation d'une préparation de xylanase pour séparer un matériau végétal, tel que du blé, en des composants utiles distincts ainsi que des procédés permettant de de réduire la viscosité ou d'assurer une séparation.
