Abstract
ABSTRACT
The current study was carried out during three successive seasons (2013:2016) to
study the effect of pre-harvest treatments (CaCl2 4%, Chitosan 1%, Combination
between CaCl2 4% and Chitosan), curing (30 °C in durations of 24; 48 and 72 hours
and 80-85 RH) and modified atmosphere packaging (MAP) on fruit quality of
"Wonderful" pomegranate cultivar during cold storage. Beside, enhance arils (fresh
cut) quality attributes during marketability life and evaluation of value chain
development in EU market.
The results obtained in this work indicated that chitosan alone or in
combination with calcium chloride as pre-harvest treatments, is effective methods for
extending the storage life of "Wonderful" pomegranate fruits. The most effective
treatment in maintaining fruit quality was CaCl2 4% + chitosan 1 % during cold
storage period at 7 ˚C.
The weight loss and decay of the fruits progressively increased with storage
time. Comparing with control fruit, the, compared with control fruit, the weight loss
and decay of packaged pomegranates was significantly reduced. In the control group,
visual quality was strongly affected by weight loss, which leads to shriveling and
browning of the skin. Indeed, The storage of ‘Wonderful’ pomegranate fruit in MAP
using commercial Xtend
sheets effectively reduced weight loss, and
maintained fruit quality for at least 5 months after harvest.
Exposure to MAP and cold storage in "Wonderful" pomegranate fruit may
modify the activity of SOD, CAT and POD. The combination of MAP and cold
storage maintained the antioxidant activity in a high level for long time, which
increased the antioxidation ability against oxidation damage.

extended by MAP used, from February to Mach and April (885.4, 1006.9, and 1222.9
$), extending Egyptian market window to week 18 competitive with South African.
The new market window for Egyptian pomegranate to be from week 30 till week 18 in
the next year (from July to end of April). By this new window pomegranate off season
were May and June only.
