In the quest to reduce food waste and promote sustainability, researchers have developed an innovative antimicrobial film that could revolutionize food packaging. The study, led by Benjatham Sukkaneewat from the Division of Chemistry at Udon Thani Rajabhat University and published in the *Journal of Biological Engineering*, explores the potential of poly(butylene succinate) (PBS) films infused with cymophenol to extend the shelf life of fresh produce while maintaining environmental safety.
The research demonstrates that these antimicrobial films not only inhibit the growth of harmful bacteria like *Staphylococcus aureus* and *Escherichia coli* but also enhance the mechanical properties of the packaging. “Cymophenol acts as both an antimicrobial agent and a plasticizer, improving the stretchability and overall performance of the films,” explains Sukkaneewat. This dual functionality makes the films particularly suitable for food packaging, where both durability and safety are paramount.
The films’ effectiveness was tested on fresh strawberries, showing a significant reduction in yeast and mold growth, particularly with thicker films. This could have substantial commercial implications for the agriculture sector, where post-harvest losses due to spoilage are a major concern. By extending the shelf life of perishable items, these films could reduce food waste and improve the efficiency of the supply chain.
Environmental sustainability is another key aspect of this research. The films were found to be biodegradable and did not hinder the growth of soil microorganisms, ensuring that they pose no threat to terrestrial ecosystems. Additionally, the study found that the survival rates of brine shrimp were significantly reduced when stored in PBS and PBS/cymophenol, indicating potential applications in marine environments as well.
The research highlights the potential for these antimicrobial films to be integrated into various food containers, offering a sustainable and effective solution to food waste. As the agriculture sector continues to seek innovative ways to reduce losses and enhance sustainability, this breakthrough could pave the way for broader adoption of biodegradable and antimicrobial packaging materials.
The findings suggest that antimicrobial PBS/cymophenol films could shape the future of food packaging, combining strong antimicrobial activity with environmental safety. This research not only addresses immediate concerns about food waste but also sets the stage for further developments in sustainable agricultural practices.
