The first stages of the leather manufacturing process have the aim of preparing hides and skins for tanning: in these stages enzymes play an important and specific role, being capable of removing undesired substances from hides and skin under mild conditions, providing a material suitable for next processing.
The enzymes, proteases, are mainly involved in the following steps of leather processing:

Soaking
This is the first operation to be carried out on hides and skins, arriving to a tannery as green or fresh, or as wet or dry salted, or as dried. Through the soaking treatment hides and skins are cleaned from dirt, flesh, blood etc.. and, in the case of dried ones, are re- hydratated and brought as much as possible back to the state of green hides.
Soaking can be carried out by using chemicals or enzymatic agents. Our soaking agents are enzymatic preparations; products with different enzymatic activity may be prepared on demand, being the one listed the most frequently required.

Bating
Proteins, which hides and skins contain in between collagen fibres, have to be removed before tanning: enzymatic bating is an indispensable operation, cannot be replaced by a chemical process, and allows to remove the unwanted proteins. As result of treatment the finished leather is pliable and its grain surface is clean, smooth and fine.
Bating may be carried out either at alkaline or acid pH conditions: suitable bating agents are available for both applications.
The listed bating agents are standard types; other bating agents, having different enzymatic activity, are available on demand.
