When
increasing
amounts
of
AC
are
added
to
peanut
extract,
the
protein
is
progressively
adsorbed
and
removed
from
solution.
When
sufficient
AC
is
added,
the
soluble
protein
becomes
undetectable.
Figure 2
indicates
that
peanut
proteins
are
adsorbed
with
equal
efficiency
at
pH 2
and 7
and
are
completely
removed
from
solution
by
an
AC/protein
ratio
of
approximately 80:1.
These
findings
corroborate
our
previously
published
results
using
a peanut
protein
mixture
prepared
from
defatted
peanut
flour
(20).
This
suggests
that
AC
could
quantitatively
adsorb
soluble
allergenic
peanut
protein
whether
encountered
in
the stomach
(pH 2)
or
intestine
(pH 7).
