The Science Behind Freshness

Freshness is not preserved by chance. It is influenced by biological processes, environmental conditions and operational decisions throughout the supply chain.

From harvest to final consumption, fruits, vegetables, flowers and other perishable products continue to breathe, age and react to their surroundings. Understanding these natural processes allows organisations to reduce waste, extend shelf life and improve overall product quality.

This page explores some of the scientific principles that influence freshness preservation and explains how technology can support better outcomes throughout the supply chain.

Originally developed for demanding military environments, technologies such as Bluezone later found applications in agriculture, food storage and logistics.

From Military Technology to Freshness Preservation

Some air treatment technologies used within modern freshness preservation programmes originated outside the food industry.

One example is Bluezone technology, originally developed for demanding military environments where air quality management played a critical operational role. Over time, similar technologies have found applications in agriculture, food logistics, storage facilities and horticultural environments.

Today these technologies may contribute to freshness preservation by helping manage airborne contaminants, odours, mould spores and ethylene concentrations.

Experience from maritime applications has shown that improved air quality management can contribute to more comfortable working environments and reduced nuisance from odours in enclosed spaces. Several vessel operators have described the technology as a practical tool for supporting environmental quality during long periods at sea.

Managing ethylene concentrations can help slow ripening processes and support freshness preservation.

Reducing Food Waste Through Better Science

A significant proportion of global food production is lost or wasted before it reaches consumers.

Much of this waste results from avoidable factors such as inadequate temperature management, improper storage conditions, excessive ethylene exposure and inefficient logistics processes.

Applying established scientific knowledge more effectively throughout production, storage and distribution networks can significantly improve product longevity, reduce waste and enhance product quality.

Ethylene management is one of several approaches used to support freshness preservation. By controlling environmental conditions and reducing exposure to ripening gases, organisations may improve shelf life while maintaining product quality throughout the supply chain.

Applications Beyond Food Logistics

Advanced air treatment technologies may also contribute to environmental quality management in healthcare and other controlled environments.

Air quality management technologies are not limited to agriculture and food logistics.

Some technologies developed to control airborne contaminants, odours and biological activity have also found applications in healthcare facilities, public buildings and other controlled environments where environmental quality is important.

Freshness Preservation for the Future

Freshness preservation is most effective when scientific understanding, operational expertise and appropriate technologies work together.

Modern supply chains increasingly rely on environmental monitoring, temperature management, air treatment technologies and data-driven decision-making to improve product quality and reduce unnecessary waste.

No single technology can eliminate losses entirely. However, combining proven scientific principles with practical logistics solutions can significantly improve product protection, operational performance and supply chain sustainability.

The science behind freshness continues to evolve as organisations seek safer, more sustainable and more efficient ways to preserve product quality.

At DEISKO, we believe that understanding the science behind product ageing and freshness preservation is an important step towards reducing waste and improving supply chain performance.
