UAEU Innovative Patent Breakthrough: Secures US Patent for Edible Biodegradable Food-Preservation Film

The Dawn of a Sustainable Innovation at UAEU

United Arab Emirates University (UAEU), the nation's flagship higher education institution, has achieved a landmark milestone by securing United States Patent US12495808B2 for an edible, biodegradable food-preservation film.52 This breakthrough, issued on December 16, 2025, underscores UAEU's commitment to interdisciplinary research addressing global challenges like food security and environmental sustainability. Developed by a team spanning agriculture and engineering, the film represents a fusion of natural materials to combat post-harvest losses, a pressing issue in the UAE's arid climate where fresh produce largely relies on imports.

The announcement, highlighted in recent reports from the Emirates News Agency, celebrates how this invention aligns with the UAE's vision for self-sufficiency and green innovation.51 As UAE universities push boundaries in applied sciences, this patent positions UAEU as a leader in bioactive packaging solutions.

Behind the Invention: The Research Team

Leading the charge is Dr. Zienab F.R. Ahmed, Principal Investigator and Associate Professor in the Department of Integrative Agriculture at UAEU's College of Agriculture and Veterinary Medicine. Her expertise in sustainable agriculture drives the project's focus on natural preservatives. Collaborating closely is Navjot Kaur, a key contributor whose work on film formulations was pivotal, and Prof. Abdel-Hamid I. Mourad, Professor in the Department of Mechanical and Aerospace Engineering, who ensured the film's mechanical robustness.5253

This interdisciplinary synergy exemplifies UAEU's research ecosystem, where faculty from diverse colleges unite to translate lab discoveries into real-world applications. Prof. Mourad noted the film's transparency, microbial resistance, and shelf-life extension capabilities from rigorous testing, while Dr. Ahmed emphasized its superiority over synthetic plastics as a food-safe barrier.51 For aspiring researchers, UAEU offers opportunities through its research assistant jobs and postdoctoral positions, fostering the next generation of innovators.

The Science: Composition and Properties

The edible film comprises primarily (at least 90 wt%) a blend of chitosan—a natural polysaccharide derived from crustacean shells known for its antimicrobial properties—and aloe vera extract from Aloe barbadensis Miller leaves, rich in antioxidants and polysaccharides. Lactic acid (2-5 wt%) aids solubility and pH control, making the film fully biodegradable and safe for consumption.52

Optimal formulations feature 85-96 wt% aloe vera extract, 2-10 wt% chitosan, ensuring a thin, transparent coating with excellent barrier functions. Studies show it reduces water vapor permeability, enhances thermal stability up to 200°C, and inhibits microbial growth, outperforming standalone chitosan or aloe films.53 This combination leverages chitosan's cationic nature to bind bacterial cells and aloe's bioactive compounds for oxidative protection.

Step-by-Step: Manufacturing the Film

Creating the film is straightforward and scalable:

• Extract fresh aloe vera gel from leaves, sterilize via filtration.
• Dissolve chitosan in 1-2% lactic acid aqueous solution (1-2 wt% chitosan).
• Mix aloe gel with chitosan solution at ratios like 60:40 (vol%), stirring homogeneously.
• Cast the solution into thin layers on trays.
• Dry at controlled temperature (40-50°C) for 24-48 hours to form flexible films.

Proven Performance: Lab and Real-World Testing

Laboratory evaluations on figs demonstrated remarkable results: coated samples showed minimal weight loss (under 5% after 28 days at 4°C), retained firmness, and suppressed fungi/bacteria compared to controls. Scanning electron microscopy revealed smooth, amorphous morphology, while X-ray diffraction confirmed no crystalline disruptions.53

Thermal analysis via TGA/DSC indicated decomposition above 250°C, suitable for logistics. Antioxidant assays (DPPH) and antimicrobial zones confirmed efficacy against E. coli and Staphylococcus. These align with global studies where aloe-chitosan coatings extend papaya shelf life by 1-2 weeks and jujube by reducing decay.7577

Addressing UAE's Food Waste Challenge

The UAE generates 3.27 million tonnes of food waste annually, costing $3.5 billion and exacerbating landfill pressures.55 Fresh produce, vital yet perishable, suffers high post-harvest losses (20-40% globally, similar locally). This film could slash these by 30-50%, supporting ne'ma's 50% reduction goal by 2030.58

Alignment with National Strategies

This innovation dovetails with UAE's National Food Security Strategy 2051, emphasizing tech-driven self-reliance amid 90% import dependency. Phase 2 plastic bans from January 2026 target single-use items, creating demand for biodegradable alternatives.96 UAEU's role amplifies, as seen in Khalifa University's 60 patents in 2025.105

UAEU's Patent Powerhouse Status

UAEU ranked 67th globally and 1st in UAE for US utility patents in 2025, granting over 50 that year, totaling 365+.87 From swarm robots to carbon sinks, its portfolio spans sustainability. This edible film joins breakthroughs like water treatment patents, showcasing higher ed's economic impact.

Future Horizons: Commercialization and Global Reach

Next steps include scaling production, field trials on UAE crops like dates/tomatoes, and partnerships with agrotech firms. Potential integration into smart packaging with sensors. Prof. Mourad envisions exports, aiding global SDGs. For faculty eyeing similar projects, check academic CV tips.
