In the present study, although interactions between OVA and starch and soy globulin were
confirmed, the effect of the state of aggregation, caused by heating
soy globulin, on the viscosity of the batter is unknown and will be
investigated in the future.
Adding OVA to soymilk increased gas cell membrane thermal
coagulation, and produced gelatinization viscosity greater than that
of batter made with water and rice flour. This may inhibit the
merging of gas cells in the center of the batter and prevent hol-
lowing of the crust. Furthermore, in soymilk batter with greater
than 2.5% added OVA, oven spring was believed to occur as the
increase in viscosity reduced the amount of water escaping from
the batter, which in turn raised the water vapor pressure within the
batter.
