In
conclusion
we
demonstrated
that
the number
of Alicyclobacillus spores
remained
stable
in most
types
of juice concentrates
during
storage
under
the most
common
conditions
employed
for
their
shipping
and
storage
However
the presence
of natural
antimicrobial
smost
likely
eriocitrin
and
hesperidin,
caused
a decline
in the counts
of Alicyclobacillus spores
in lemon juice concentrates
This reduction was
more
pronounced
in cloudy lemon juice concentrates
It is suggested
that
natural
antimicrobials
present
in lemon juice concentrate
can
inhibit
germination
and
outgrowth
of Alicyclobacillus spores
if a dilution
of 1:9
is used
during
detection
procedures
Thus
a modification
in the
dilution
proportion
used
in the detection
procedures
from 1:9 to 1:19
is suggested
mainly
for juice concentrates
in which
natural
compounds
presenting
antimicrobial
activity
may
inhibit
the germination
and outgrowth
of Alicyclobacillus spp.
These findings
have relevance
for the juice industry
and may
impact
the success
of screening
and
quality
control
programs
as well
as the costs
resulting
from spoilage
episodes.
