Dragon fruit, a “gem among fruits” native to Central America, has firmly taken root across Asia, emerging as one of the region’s most dynamic traded fruits. Today, Asia serves as the world’s primary production hub, with exports reaching markets throughout the Americas and Europe.

Yet behind this vast supply chain lies a critical challenge: ensuring that this delicate fruit maintains optimal quality throughout long-distance transportation. Meeting this challenge is essential to preserving its global competitiveness. Against this backdrop, Produce Report invited Dr. Gary Ward, chief technology officer of StePacPPC [3], a global leader in modified atmosphere packaging for fresh produce, to discuss innovative solutions [4] for safeguarding dragon fruit quality in transit.

Three Major Challenges: Water Loss, Color Degradation and Microbial Decay

Ward pointed out that dragon fruit faces three primary challenges during storage and long-distance transportation. First, the fruit is highly susceptible to moisture loss, leading to weight reduction and causing the peel and bracts to shrivel. Second, the vibrant skin color can easily fade and lose its visual appeal. Third, it is relatively vulnerable to microbial decay by plant pathogens, increasing waste levels.

For consumers, the visual appeal of dragon fruit is of paramount importance. Bright skin color and firm bracts are the foremost indicators of freshness and quality. This is not merely an aesthetic concern — it directly affects market pricing. In quality-driven markets such as China, the visual condition of the fruit often determines whether it can access premium retail channels.

Traditional Approaches: Passive Protection Falling Short

Conventional packaging technologies often struggle to meet these critical requirements. Ward explained that dragon fruit has traditionally been transported naked or with only basic packaging and the quality deteriorates during long-distance shipments.

Ward additionally noted, “Dragon fruit remains alive after harvest — it continues to respire and lose moisture. Without actively managing its microenvironment, weight loss, shriveling and color fading are almost inevitable outcomes.”

A Breakthrough Approach: Innovative Application of Advanced Polymer Films

To address these industry challenges, StePacPPC has introduced a targeted solution developed and field-tested over three years: a customized MAP system specifically designed for dragon fruit. This solution utilizes advanced polymer film materials with a relatively high water-vapor transmission rate, effectively regulating humidity within the package and helping to prevent moisture loss. Combined with laser micro-perforation technology to optimize the internal gas composition, this system enables dragon fruit to remain fresh under refrigerated conditions for more than three weeks during long-distance transport.

Compared with conventional packaging traditionally used for dragon fruit, StePacPPC’s MAP technology actively manages oxygen, carbon dioxide and moisture levels rather than merely containing the fruit. This approach slows respiration, reduces dehydration and inhibits microbial decay, thereby preserving the fruit’s vibrant color and overall freshness much better than traditional packaging solutions.

Research and Development Journey: Three Years of In-Depth Collaboration With Exporters

Ward revealed that this solution was developed based on StePacPPC’s expertise in produce physiology, pathology and packaging interaction. The company conducted in-depth research into the respiration characteristics, moisture sensitivity and key postharvest storage challenges of dragon fruit. By carefully adjusting the film’s permeability properties, the research team was able to create an optimal internal gas environment under real-world supply chain conditions. At the same time, the company worked closely with customers to optimize postharvest handling procedures, maximizing the packaging’s preservation performance. The entire research and development process spanned more than three years and involved close collaboration with multiple dragon fruit exporters.

To date, the packaging has been successfully applied to long-distance sea freight shipments of dragon fruit from Ecuador to North America and Europe, allowing excellent quality to be maintained even after voyages exceeding three weeks.

Commercial Value: Quality as Competitiveness

In Ward’s view, dragon fruit exporters in Asia can benefit from Xtend MAP, which serves as a key tool enabling dragon fruit to be shipped by sea to more distant markets and arrive in premium condition.

“The market is changing, and the challenges are changing, but one thing remains constant: consumers are willing to pay for freshness,” Ward concluded. “As long as dragon fruit arrives at its destination looking better, it can secure a competitive edge in the marketplace.”
