Current state-of-the-art of
postharvest technologies
• Extended period of cold storage
• Automated process for extracting the
pomegranate arils
• Production of a high-quality
pomegranate juice and wine from arils
• A new product – frozen arils
• Preliminary work for producing food
additives and cosmetic products from
the seeds & rind
Cold Storage of Pomegranate Fruit
Conventional Cold Storage
Special Bags
for longer storing of fruits
Controlled Atmosphere (CA) Cold
Storage
Arils extraction
7 years ago the issue of
relieving the pomegranate
arils was solved!
After a concerted effort of R&D at
the Institute of Agricultural
Engineering in Israel, a unique and
novel technique was developed for
extracting the pomegranate arils
Schematics of the arils extraction
machine – R&D version
Commercialization
The extraction system is
manufactured by “Juran Metal
Works” in Israel and is being
offered in different configurations.
More than 30 systems were sold
worldwide.

Pomegranate Utilizations
• The whole fruit for decorations
• Consumed as fresh fruit
• Consumption of “fresh-cut” arils packed in
MAP packages and stored on chilled shelves
• Fresh juice from the whole fruit
• Fresh juice from only the arils
• Wines, liquors, Juice concentrates
• Frozen arils
• Food additives, medicinal supplements,
cosmetic products (produced from the fruit’s
arils, seeds & peel)
• Red dye (antocyanine) for the food industry
• processing of hides

Remaining technological
gaps & future challenges
• Extending the storage period of arils
• Eveloping a non-destructive internal
quality sorting machine
• Different processes should be
developed for the utilization of the
arils, juice, seeds and rind for a variety
of food suplements & cosmetic
products
• Continuing the medical research
The challenge is big!
Will the industry rise to meet
the challenge?
