Human Gut-Derived Postbiotics Draw Attention as Next-Generation Food Packaging Materials
- Research achievement by the team of Professor Young-Mok Kim at Pukyong National University … proven effects in maintaining refrigerated salmon freshness as well as antibacterial and antioxidant properties
- Published in the international journal <Chemical Engineering Journal> in the field of chemical engineering

A research team led by Young-Mok Kim, Professor of the Major in Food Science and Engineering at Pukyong National University, has developed an active packaging film for food packaging using human gut-derived lactic acid bacteria metabolites (postbiotics).
The study was conducted by Geum-Jae Jeong, Ph.D. at the Marine Bionics Convergence Technology Center of Pukyong National University, and Ye-Hyun Jo, a master’s student in the Interdisciplinary Program in Blue Food Convergence (co-first authors), together with Professor Young-Mok Kim (corresponding author) of the Major in Food Science and Engineering. The team published the paper titled ‘Chitooligosaccharide/Polyvinyl Alcohol Films Incorporated with Human Gut-Derived Postbiotics for Active Food Preservation.’
This study has been accepted for publication in the June 2026 issue of the internationally renowned journal Chemical Engineering Journal (IF 13.2, top 3% in JCR) in the field of chemical engineering.
In this research, the team developed a next-generation active food packaging material by producing a composite film based on chitooligosaccharide (COS) and polyvinyl alcohol (PVA) incorporated with human gut-derived postbiotics, thereby imparting antibacterial and antioxidant functions.
In particular, the composite film demonstrated its potential as a functional packaging platform by effectively incorporating postbiotics while maintaining excellent mechanical strength, biocompatibility, and stability. Because postbiotics do not use live microbial strains, they offer advantages over conventional probiotic-based materials, including greater safety and storage stability. In addition, their relatively simple production process makes them more suitable for mass production and industrial applications.
The research team conducted verification experiments using refrigerated salmon and found that the film effectively suppressed microbial growth during storage while delaying lipid oxidation and protein degradation, demonstrating outstanding effects in maintaining the freshness and quality of the salmon. These findings show that the postbiotics incorporated into the packaging film can perform practical preservation functions even under refrigerated distribution conditions.
This study was carried out in collaboration with the Korea Disease Control and Prevention Agency (KDCA) and is significant in that it presents a next-generation food packaging technology that overcomes the limitations of live bacteria-based functional materials while simultaneously ensuring safety, economic feasibility, and practicality. The technology is expected to be widely applied in the development of eco-friendly, high-functional packaging materials for fisheries products and fresh foods in the future.
Meanwhile, this research was supported by the University-Focused Research Institute Program of the National Research Foundation of Korea and the Marine Blue Tech Future Leader Training Project of the Korea Institute of Marine Science & Technology Promotion (KIMST). <Pukyong Today>
