Packaging extends pomegranate shelf life

StePac L.A., Ltd., which has been pioneering advances in pomegranate packaging since 2003, now introduces a range of sustainable packaging solutions for preserving the freshness and extending the shelf life of pomegranates and their extracted arils.

The range includes new recyclable solutions, as well as packaging formats tailored to automation of both bulk and retail packing. These will be showcased at the upcoming Fruit Logistica in Berlin, February 5-7, hall 26, booth #D10.

Although whole fresh pomegranates have a tough exterior, challenges arise when they are stored for a prolonged period. In the absence of proper protection, the fruit can suffer significant dehydration and weight loss, causing it to shrivel. This may be accompanied by the development of skin blemishes and crown decay that eventually leaches into the fruit and impairs the quality and taste of the arils.

Pomegranate growers and packers can load freshly picked pomegranates directly at the orchard and store up to 400kg of the fruit in a specialised StePac Xtend^® bin liner for periods of three months or longer

From orchard to table

StePac’s pomegranate packaging portfolio incorporates long storage packaging formats to meet the requirements of growers seeking glut management solutions for post-harvest bulk storage.

Pomegranate growers and packers are now able to load fresh-picked pomegranates directly at the orchard and store up to 400kg of the fruit in each specialised StePac Xtend^® bin liner for periods of three months or longer, with no negative effect on the fruit. This is in addition to storage liners for weight of 10-80kg that are already widely used in many countries.

The Xtend line also includes unique carton liners that offer the ideal solution for maintaining fruit quality during the lengthy shipments to distant locations.

Leaner flowpack packaging for whole fruits

StePac developed film structures containing a unique sealing layer that facilitates leaner packaging and induces savings of up to 40% in material use as well as reduced labor costs, by enabling pomegranates to be flow-packed in both bulk and retail formats.

100% recyclable retail packaging for arils

The company recently finalized development of fully recyclable Xgo™ lidding films and standing pouches to add to this category of retail-packaging products. These solutions are designed to inhibit postharvest microbial decay and extend the shelf life of extracted pomegranate arils for up to 17 days, preserving the fruit’s organoleptic properties. The lidding films are available in lean easy peel and resealable formats.

The company’s comprehensive range of lean and sustainable packaging solutions is designed to maintain pomegranate freshness throughout all stages of the supply chain. The technology is based on a unique modified atmosphere packaging (MAP) system that reduces respiration rates and ethylene production for a combined effect of slowing down ageing and ripening. It also inhibits the proliferation of pathogens.

Water vapour transmission technology enhances performance

StePac has developed a comprehensive repertoire of films with built-in abilities to regulate water-vapour transmission rates as well as provide optimal modified atmosphere conditions. The films incorporate distinct properties to cater to a range of pomegranate packaging applications.

“During prolonged storage of this fruit, it is paramount to strike the perfect balance between eliminating excess free moisture to mitigate the risk of microbial decay and to concurrently avoid excessive product dehydration,” explains Gary Ward, Ph.D., Business Development Manager for StePac. “Such balance depends on multiple synergistic factors, including surface area to volume ratio, produce weight, supply chain length, and shipping and storage conditions.”

“Pomegranates are in demand in every continent.” Ward enthuses. “The global reach of our technology is instrumental in addressing the challenges facing the pomegranate industry and for ensuring that both the whole fruit and the extracted arils reach the consumers— wherever they might be — in prime condition, while keeping waste to a minimum. Our holistic vision and pragmatic approach are embedded in a range of complex structures and packaging formats that deliver the extended shelf life and sustainability principles our customers seek. This approach evolved from our deep-rooted understanding and 25-year history of researching fresh produce pathology and physiology and its interaction with packaging design.”
