StePacPCC, a global leader in innovative Modified Atmosphere Packaging (MAP) solutions for fresh produce, has introduced a groundbreaking packaging solution designed to preserve the freshness and vibrant appearance of pitaya (dragon fruit). This is especially crucial during the lengthy transportation from Ecuador to markets in the US and Europe.
StePacPPC’s technical team adeptly adapted the advanced Xtend® Modified Atmosphere/Modified Humidity (MA/MH) bulk packaging films to meet the specific postharvest needs of pitaya. As a result, the exotic fruit can reach consumers in peak condition and appearance.
Native to Central and South America, pitaya is celebrated for its striking colors, sweet tropical flavor, and its nutritional benefits, being rich in antioxidants and vitamins. However, it faces numerous challenges during international sea shipments that can extend to three weeks or more. High respiration rates, moisture loss, and vulnerability to microbial decay begin to affect the fruit’s quality just days after harvest.
“South American pitaya growers often struggle to reach distant markets with this high-demand delicacy,” explains Gary Ward, Ph.D., CTO for StePacPPC. “Even in optimal cold chain conditions, the long sea transport from Ecuador to North America and Europe can degrade the delicate fruit, leading to weight loss, shriveling of the skin and bracts, and dulling of its vibrant peel, along with occasional microbial decay. These issues not only diminish the fruit’s appeal and marketability but, most importantly, negatively impact its quality and freshness.”
The innovative packaging solution balances oxygen and carbon dioxide levels while maintaining moisture control, thereby safeguarding the pitaya throughout prolonged storage and shipment. This packaging reduces dehydration, mitigates the fruit’s respiration rate, and inhibits microbial decay, effectively slowing down deterioration.
StePacPPC’s Xtend® packaging has proven instrumental in preserving the bright color and glossy finish of the decorative pitaya, while also maintaining the firmness of the bracts, a key indicator of quality and freshness that tends to wilt when dehydrated. The development of this specialized film took over three years and involved close collaboration with pitaya exporters to fine-tune postharvest handling, optimize packaging design, and enhance overall performance.
The Science of Freshness
StePacPPC’s packaging technology leverages the principles of modified atmosphere packaging, which effectively slows respiration rates, inhibits ethylene gas production (responsible for ripening and aging), and suppresses microbial decay. This innovative approach is a prime example of sustainable food and drink packaging solutions.
A key differentiator for StePacPPC is its extensive range of film structures, all featuring antifog properties and varying water vapor transmission rates (WVTR). This versatility allows for precise moisture management tailored to the unique requirements of various produce types, balancing the reduction of microbial decay risk with prevention of excessive weight loss while ensuring excellent product visibility. When combined with optimized modified atmospheres, these attributes substantially extend the shelf life of tropical fruits beyond what traditional packaging can achieve.
“This breakthrough has opened new avenues for exporters, enabling them to reach more distant markets with fruit that arrives in prime condition. This applies not only to Ecuador and South America but also to other key producing regions like Southeast Asia—a major hub for dragon fruit cultivation and export,” adds Ward. “The success in Ecuador represents how StePacPPC identifies fresh produce challenges and collaborates with customers to create a new packaging paradigm.”
MAP Packaging Keeps Tropical Fruit Vibrant and Fresh
This specialized pitaya packaging film is the latest addition to StePacPPC’s portfolio, which already includes highly effective solutions for other tropical fruits, including bananas, passion fruit, lychee, longan, rambutan, mango, and papaya.
StePacPPC’s Xtend® bulk and Xgo™ flow-pack retail packaging for passion fruit are already established as industry standards for shipments from Colombia to the USA and Europe. This packaging enhances the shelf life of passion fruit while effectively managing a weeks-long cold-chain shipment, slowing ripening, and reducing the risk of common peel defects like wrinkles and mold.
Additionally, StePacPPC’s preformed bulk and retail bags are widely used in South Africa for packaging and shipping green bananas. These bananas can be ripened in the sealed bag, where the modified atmosphere slows ripening, allowing more leeway for distribution and extending the consumption window for retail-packed bananas.
“StePacPPC is leading the way in packaging technology for fresh produce,” states Ward. “We custom design lean packaging that preserves the freshness of tropical fruits for extended periods. This innovation allows for longer storage, ensures smarter logistics, dramatically improves quality, reduces food waste, and unlocks new markets for this in-demand category of fruits.”
