Brunette Girl Strips From The Leather Dress At The Fireplace

Proteases are the most commonly used enzymes in leather production. The enzyme used should not damage or dissolve collagen or keratin, but should be able to hydrolyze casein, elastin, albumin, and globulin-like proteins, as well as non-structured proteins which are not essential for leather making. This process is called bating.
Lipases are used in the degreasing operation to hydrolyze fat particles embedded in the skin.
Amylases are used to soften skin, to bring out the grain, and to impart strength and flexibility to the skin. These enzymes are rarely used.
