Values are given as mean ± SD from triplicate determination
Means with different superscripts in the same column (small letter) and row (capital letter) indicate significant difference in the gelatin yields at P < 0.05. Treatment levels 0, 5, 10, 15, 20 and 25 show the unit of enzymes used per gram of skin
