The
peculiar
flavour
of chocolate
products
is
also
affected
by
the
presence
of
other
added
ingredients
(e.g.
milk
solids,
nuts,
vanilla).
In
milk
and
white
chocolate,
for
example,
flavour
and
aroma
is
sig-
nificantly
affected
the
presence
of
milk
derivatives,
sugar
and
cocoa
and
on
they
are
processing
before
their
addition
[8,9]. Undesired
aroma
compounds
that
affect
the
overall
typical
flavour
may
be
present
in chocolate
products
due
to several
causes
including
the
use
of
low
quality
raw
materials
(e.g.
cocoa
beans
produced
by
an
incorrect
fermentation)
and
the
application
of
not
proper
process
conditions
[1,10]. Moreover,
during
storage
and
distribution,
phys-
ical
processes
and
oxidative
reactions,
may
alter
flavour
release
and/or
originate
secondary
volatile
compounds
and/or
induce
the
decrease
of
some
typical
aromas
highly
affecting
the
overall
flavour
acceptability
of
the
product.
