Miller and Hoseney (1993) showed that the cakes obtained after
the inclusion of xanthan gum in the batter formulation showed
similar or better characteristics, in terms of volume, height and
shrinkage, than those of the control cakes. The reasons for replacing
egg with hydrocolloids and emulsifiers are related to their functional
properties. Hydrocolloids have good functional attributes
such as water binding, viscosity, foaming, emulsifying, gelling,
solubility and textural improvement while emulsifiers are known
for their crumb softening and antistaling effect
