Egg white was subjected to proteolysis by ficin, bromelin, papain, trypsin and protease; changes in functional properties were monitored. Many of the changes observed were due to the addition of enzyme rather than actual proteolysis (e.g., foam volume increase, foam stability decrease, and angel cake volume increase). The angel cake volume showed a further increase with proteolysis; however, off‐flavors were also noted. In experiments with ficin and bromelin, proteolysis by both enzymes decreased the coagulum strength while only ficin decreased the amount of noncoagulable protein.
