Abstract

Background

Conventional petroleum-derived plastic food packaging poses risks to human health and environmental sustainability, while underperforming in preserving freshness and extending shelf life. This has spurred interest in biopolymers as sustainable alternatives. Konjac glucomannan (KGM), a natural biopolymer, stands out for its non-toxicity, film-forming ability, biodegradability, and biocompatibility, offering a sustainable solution to overcome conventional plastics' limitations.

Scope and approach

This review explores KGM's sources, production technologies, properties, and applications in food packaging. A literature search (2020–2025) using PubMed, Web of Science, and Scopus focused on peer-reviewed studies relevant to KGM-based films. Results show that KGM films enhance shelf life of perishable foods (e.g., fruits, vegetables, meats) by improving moisture retention, gas barriers, and antimicrobial activity.

Conclusion

Despite advantages, KGM films face challenges like mechanical strength limitations and humidity sensitivity. Strategies such as blending with biopolymers and incorporating nanoparticles improve performance. KGM-based packaging is emerging as an eco-friendly alternative to petroleum plastics, aligning with sustainability goals. Future research should optimize production processes and commercial scalability.

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
