More specifically,
a cake batter represents a complex emulsion and foam system
which is processed by being heat set. The baking of cakes leads to
a light, aerated structure as well as to the formation of a great
amount of volatile compounds, which play a major role in developing
their typical flavour. These compounds are mainly the result
of the Maillard reaction, which occurs between reducing sugars and
the -NH2 function of amino acids, peptides and proteins. The
selection of raw materials as well as alteration of the making
process can modify cake structure and aroma composition.
