Abstract

The present invention relates to a method for modifying lignocellulosic material having phenolic groups or derivatives of phenolic groups. The method comprises the steps of oxidizing the phenolic groups or the phenoxy derivative groups of the lignocellulosic material to quinines, quinone derivatives or other carbonyl groups, and contacting the oxidized fibre material with a biochemical agent comprising a reactive nucleophilic group, said biochemical agent forming a covalent bond with the lignocellulosic material. The invention relates also to modified lignocellulosic products.
