Modified-atmosphere-packaged
sweet
persimmons
experience
significant
quality
loss
due
to
tempera-
ture
fluctuations
in
the
food
supply
chain,
which
cause
an
imbalance
between
respiration
and
package
gas
permeation.
This
imbalance
results
in
the
package
atmosphere
deviating
from
the
tolerable
range.
In
this
study,
a
master
packaging
system
was
designed
to
maintain
a
suitable
modified
atmosphere
around
the
fruit
during
pre-sale
chilled
storage
and
during
retail
display
to
preserve
freshness.
A
50-
m-thick
low-density
polyethylene
(LDPE)
outer
liner
bag
containing
46
individual
fruit
packages
(30-
m-thick
oriented
polypropylene
(OPP)
film
bag
with
a
micro-perforation
of
about
60
m)
was
placed
within
a
corrugated
paperboard
box.
Master
packaging
systems
with
and
without
the
absorbent
sachets
were
stored
for
122
d
at
0
◦
C
and
were
periodically
opened
to
remove
and
store
the
individual
primary
package
units
for
10
d
at
10
◦
C
to
simulate
retail
display
conditions.
The
master
packaging
systems
were
com-
pared
to
10-kg
bulk
packages
containing
individual
fruit
inside
a
50-
m-thick
LDPE
film
bag
in
terms
of
package
atmosphere
and
fruit
quality.
Individual
fruit
packages
consisting
only
of
30-
m-thick,
micro-
perforated
OPP
films
without
an
outer
liner
bag
were
subjected
to
the
pre-sale
0
◦
C
storage
for
comparison.
The
master
packaging
systems
maintained
an
atmosphere
with
O
2
concentrations
of
0.8–3.9%
and
CO
2
concentrations
of
8.4–15.0%
around
the
fruit
during
storage
at
0
◦
C
and
during
display
at
10
◦
C.
The
high-
temperature
retail
display,
after
chilled
storage
at
0
◦
C,
resulted
in
a
drastic
decline
in
quality,
even
with
some
alleviation
offered
by
the
master
packaging
system.
The
overall
benefits
were
reduced
weight
loss,
reduced
physiological
deterioration
(e.g.,
flesh
softening
and
surface
blackening)
and
better
retention
of
firmness
and
ascorbic
acid
during
the
chilled
storage
and/or
the
display
conditions.
