Consumers increasingly want food that stays fresh for longer while containing fewer artificial ingredients. At the same time, manufacturers are under pressure to reduce food waste, improve supply chain efficiency, and meet demand for clean-label products.
A newly granted patent may offer a solution.
In March 2026, Coroos International N.V. secured patent protection for its REPFED (Refrigerated Processed Foods of Extended Durability) technology through the invention titled “Method to Preserve Packaged Food Products” (published as WO2025017154A1). The patent describes a preservation process that uses controlled heat treatment, rapid cooling, and nitrogen-assisted packaging to extend refrigerated shelf life without relying on conventional chemical preservatives.
The invention is significant because it shifts the focus of preservation from additives to engineering. Instead of changing what goes into the food, it changes how the food is processed.
The REPFED Process
According to the WO2025017154A1 patent, the REPFED method follows a carefully designed sequence:
- Food is heated to 110°C to 115°C.
- The heating step lasts for less than one minute.
- The product is then flash-cooled to refrigeration temperatures.
- Packaging is carried out using nitrogen to reduce oxygen exposure.
- The process is designed to extend shelf life without adding chemical preservatives.
Rather than modifying the recipe, the innovation focuses on optimizing processing conditions to maintain freshness.
Why This Patent Is Significant
The food industry has long struggled to balance two competing objectives: extending shelf life while maintaining simple ingredient lists.
The REPFED process addresses this challenge by relying on processing technology instead of preservatives. If commercialized successfully, it could allow manufacturers to produce foods with fewer additives while maintaining refrigerated stability.
Equally important is the patent strategy itself. The invention titled “Method to Preserve Packaged Food Products” protects the manufacturing process rather than a novel ingredient. This reflects a broader shift in food innovation, where companies increasingly seek competitive advantage through proprietary processing methods.
The Science Behind the Method
Food spoilage is typically driven by microbial growth, oxidation, and enzyme activity.
The REPFED process combats these factors through multiple mechanisms:
- High-temperature treatment reduces microorganisms.
- Rapid cooling minimizes thermal damage while stabilizing the product.
- Nitrogen packaging lowers oxygen levels that accelerate spoilage.
- Refrigerated storage helps maintain quality over extended periods.
The combination of these steps is intended to preserve freshness without conventional synthetic preservatives.
Industry Trends Supporting This Innovation
Consumer demand for preservative-free and clean-label foods continues to grow as shoppers pay greater attention to ingredient lists.
At the same time, manufacturers are investing in technologies that can:
- Reduce food waste.
- Improve logistics and distribution.
- Support premium “natural” branding.
- Extend refrigerated shelf life without compromising quality.
As a result, process innovation has become an increasingly active area of patenting across the global food industry.
What This Could Mean for the Food Industry
The timing of the REPFED patent is particularly important given the scale of food waste worldwide.
According to estimates from the Food and Agriculture Organization (FAO) and the United Nations Environment Programme (UNEP), approximately 13% of food produced globally is lost before reaching retail, while an additional 19% is wasted at retail, food service, and household levels. Food loss and waste are also responsible for roughly 8% to 10% of global greenhouse gas emissions.
If REPFED performs as described, it could help manufacturers reduce spoilage throughout transportation, warehousing, and retail distribution without relying on conventional preservatives. This could strengthen supply chains while supporting sustainability goals and consumer demand for minimally processed foods.
The patent also enters a competitive landscape where companies currently rely on technologies such as High Pressure Processing (HPP), modified atmosphere packaging, aseptic processing, and natural antimicrobial ingredients. By protecting a process based on controlled heat treatment, rapid cooling, and nitrogen-assisted packaging, Coroos may distinguish itself from existing preservation technologies and encourage competitors to pursue alternative innovations.
Potential Impact Beyond Traditional Foods
Although developed for packaged foods, the underlying preservation approach may have broader applications.
Manufacturers of medical nutrition products, hospital meals, and specialized foods for elderly or immunocompromised populations often seek longer refrigerated shelf lives while minimizing unnecessary additives. A process that extends durability through engineering rather than preservatives could become attractive in these sectors if validated for relevant applications.
While the REPFED patent is not specifically directed toward pharmaceutical products, it reflects a wider industry trend toward preservation technologies that prioritize process optimization over chemical intervention.
Business and Commercial Impact
If adopted at scale, REPFED could offer several commercial advantages:
Longer Refrigerated Shelf Life
Products may remain marketable for longer without conventional preservatives.
Clean-Label Appeal
Manufacturers could simplify ingredient lists while meeting growing consumer demand for natural foods.
Reduced Food Waste
Longer-lasting products have the potential to reduce spoilage across transportation networks, retail stores, and households.
Supply Chain Efficiency
Additional refrigerated shelf life provides manufacturers and retailers with greater flexibility in inventory management and distribution planning.
The Intellectual Property Perspective
One of the most compelling aspects of REPFED is that its competitive advantage lies in the production method rather than the formulation.
By patenting the invention “Method to Preserve Packaged Food Products” under publication number WO2025017154A1, Coroos has secured protection for its preservation methodology. This means competitors cannot freely replicate the patented process in jurisdictions where corresponding patent rights are in force.
The case illustrates a broader shift in innovation strategy. Increasingly, companies are competing not only through new ingredients but also through proprietary manufacturing techniques that improve product quality, efficiency, and sustainability.
Challenges to Commercial Adoption
Despite its promise, widespread implementation will depend on several factors:
- Investment in specialized processing equipment.
- Validation across different food categories.
- Compliance with food safety regulations.
- Maintaining taste, texture, and nutritional quality after processing.
- Demonstrating economic viability at industrial scale.
Ultimately, market adoption will depend on whether the technology consistently delivers both quality improvements and cost-effective production.
Conclusion
The March 2026 patent for “Method to Preserve Packaged Food Products” (WO2025017154A1) highlights how food preservation is evolving beyond chemical additives toward advanced processing technologies.
By combining 110°C to 115°C heat treatment, rapid cooling, and nitrogen-assisted packaging, the REPFED process aims to extend refrigerated shelf life while preserving a clean-label profile. If successful at scale, it could reshape how manufacturers think about freshness, reduce food waste across supply chains, and intensify competition among companies developing next-generation preservation technologies.
