Pepsin has been used as a substitute for rennin in the production of certain cheeses. Treatment of hides. Pepsin is used by the leather industry to remove undesirable traces of remaining tissue, such as hair and fat, from partially processed hides. This enzymatic treatment is called âbatingâ the hides.
The optimum temperature for pepsin is between 30 degrees Celsius and 40 degrees Celsius.Activity has been reported outside of this range.he optimum pH of pepsin is pH2. Pepsin is found in the stomach and it is protease enzyme that digest protein into smaller molecule. The stomach is suitable place for it becau â¦ se it is acidic, so it's activity increases in the acidic environment. 21 people found this useful.
