In this final beamhouse process, residues of non-collagen protein and other interfibrillary material are removed. This leaves the pelt clean and relaxed, ready for the tanning operation.

The modern approach to bating is to use microbial enzymes derived from either fungal or bacterial sources. These en­zymes can be used alone or in combination, depending on the article in question. The fungal type is especially suited to shoe uppers, whereas a combination is used for softer arti­cles. In both cases high-quality leather is obtained with good scud loosening and a fine and delicate grain through a mild and gentle bating process.

Processing conditions: Standard bating operations.
