Abstract

The invention relates to a process for the production of pelts ready for tanning, from hides and skins, using proteolytic and lipolytic enzymes in the beam house, wherein in at least one of the part-steps in the beam house consisting of a) the lime in the pH range 11.5 - 14 and the b) bate in the pH range 5 - 11.5 in the aqueous liquors corresponding to these part-steps, alkaline lipases (E.C.3.1.3.) with an activity optimum in the pH range 9 - 11 are employed.
