by number of microperforation [16]. Most of the water
loss from citrus fruit during storage is lost from the peel
tissue rather than from pulp [5]. Sealing lemon in
microperforation polyethylene bags was superior to a
conventional solvent wax treatment in reducing
transpiration during storage. In contrast to transpiration,
microperforated of polyethylene bags did not alter the rate
of CO and O exchange by grapefruit. Vines and
22
Oberbacher [17] found that although respiratory rates of
oranges and grapefruit were not appreciably affected by
thicker than normal wax coating, the internal CO
2
nevertheless increased and the O decreased in relation to
2
thickness of applied wax. Porat et al . [6] reported that
the microperforated XF10 liner enabled a modified
atmosphere to form inside the package, with elevated CO
2
and decreased O levels, whereas the gas atmosphere
2
composition inside the macroperforated XF10 film hardly
changed and remained more or less similar to that of
ambient air. However, Hewett and Thompson [14] also,
reported that concentration of CO increase while those of
2
O decrease when apples fruit cv. “Cox Orange Pippin” are
2
stored in microperforated polybags; values of 6.2% CO
2
and 14.7% O after 6 weeks at 1°C.

The microperforated polyethylene bags used in
this study did not appear to have any deleterious
effect on the juice quality factors determined; however
storage temperatures did not alter juice quality.
Science the microperforated polyethylene bags were
effective in maintaining fresh fruit appearance at
temperatures up to and perhaps higher than 20°C, one
might be tempted to store warped citrus fruits at
non-refrigerated temperatures. Sealing acid lime fruit in
microperforated polyethylene bags can extend their
storage life, but only when the temperature is properly
controlled.
