ovotransferrin . Lysozyme and ovomucoid denature around 75e79 C, whereas ovalbumin denatures
at 84 C and ovoglobulins even later. Ovomucin does not denature. The threedimensional
network of egg white gel is formed by hydrophobic,electrostatic and SS bonds of denatured proteins. Ovalbumin is the most important protein in egg white
because of its high abundance and its free SH groups
which are important for gel formation. The free SH groups of
ovalbumin are exposed during heating and can then form intermolecular
SS bonds . During egg storage, ovalbumin is
converted into S-ovalbumin , a more thermostable
form with a denaturation temperature about 8 C higher than that
of the native form. The higher thermostability
of S-ovalbumin impacts the protein network formation in
pound cake baking and impacts texture.
