Notes:
Albumen from eggs of a strain of White Leghorn hens was treated with various proteolytic enzymes (papain, ficin, protease, bromelin and trypsin) for 18 hr at 34°C. Following enzyme treatment the nonprotein nitrogen, measured as moles of tyrosine released per minute, was found to range from 1.1 × to 10-3 4.8 × 10-3. All treatments were found to cause some changes in the electrophoretic behavior of albumen. The pH of enzyme-treated albumen ranged from 6.2 (protease) to 8.4 (trypsin). Enzymatic treatment of albumen, with the exception of papain, improved angel food cake volumes from 3 .9%). In gcneral, enzyme-treated albumen showed a 6–16% increase in foam volume; however, the foam stability was inferior compared to the control.
