Abstract

A method of producing mechanical pulp, comprising impregnation of fiber material with an enzyme-containing aqueous liquid prior to defibration and refining of the fiber material to produce a mechanical pulp. According to the invention, said enzyme-containing aqueous liquid is a pectinase-containing aqueous liquid. The invention is also related to the mechanical pulp thus produced.
