“…In India, as much as 40% of fresh produce are wasted during postharvest handling, storage, and transportation [1]. Physical injury during harvesting, microbial growth, and oxidative deterioration are primary causes of loss of freshness, quality, and shelf-life in fresh produce [2]. These necessitate strategies to enhance postharvest life in order to cater to their increasing global demands and longevity of the fresh products.…”

In the context of emerging global concerns with synthetic plastic packaging, alternative natural biodegradable packaging materials are gaining increasing attention for food packaging applications. In this study, chitosan and gelatin nanocomposite hybrid films containing green synthesized zinc oxide (ZnO) nanoparticles (NPs) were developed and microstructural properties were studied. Antimicrobial activity of the developed films was evaluated using both Gram negative (Escherichia coli) and Gram positive bacteria (Staphylococcus aureus). Green synthesis protocol was used for the precipitation of ZnO NPs using fruit extract of Cassia fistula. The as-synthesized polyhedral ZnO NPs were in the range of 20–40 nm (average size ≈29 nm). Reinforcement with ZnO NPs in the hybrid films lead to improved thermal stability, elongation-at-break (EAB), and compactness properties. The developed films with 2% and 4% ZnO NPs showed a smooth, compact, and heterogeneous surface morphology compared to the control (chitosan-gelatin hybrid) films. Disc diffusion assays showed that the nanocomposite film had significant antimicrobial activity against E. coli. The developed hybrid nanocomposite films have potential to be developed as biodegradable alternative for postharvest packaging of fresh fruits and vegetables.

“…In contrast, when tested with S. Typhimurium, larger CSNPs have shown a greater effect, possibly due to the varied cellular envelop composition compared to E. coli [ 83 ]. Additionally, some studies have shown a relationship between molecular weight and inhibitory effects of chitosan [ 110 ]. Hence, more studies are needed to unravel the detailed mechanism of action of CSNPs against different bacterial strains, and it may vary according to the bacterial strain and their cell membrane/envelop composition.…”

Chitosan has emerged as a biodegradable, nontoxic polymer with multiple beneficial applications in the agricultural and biomedical sectors. As nanotechnology has evolved as a promising field, researchers have incorporated chitosan-based nanomaterials in a variety of products to enhance their efficacy and biocompatibility. Moreover, due to its inherent antimicrobial and chelating properties, and the availability of modifiable functional groups, chitosan nanoparticles were also directly used in a variety of applications. In this review, the use of chitosan-based nanomaterials in agricultural and biomedical fields related to the management of abiotic stress in plants, water availability for crops, controlling foodborne pathogens, and cancer photothermal therapy is discussed, with some insights into the possible mechanisms of action. Additionally, the toxicity arising from the accumulation of these nanomaterials in biological systems and future research avenues that had gained limited attention from the scientific community are discussed here. Overall, chitosan-based nanomaterials show promising characteristics for sustainable agricultural practices and effective healthcare in an eco-friendly manner.

Due to higher expectations for health in recent decades, the issues of food preservation and safety are now attracting more and more attention. Therefore, research and development of food packaging materials is of important practical significance. While the wide use of functional plastic packaging brings great convenience to the food industry, serious problems also appear subsequently, such as source exhaustion, plasticizer transfer, and other potential food safety hazards, which pose great challenges to researchers. In order to overcome these shortcomings, the natural polysaccharide chitosan has emerged as a suitable food packaging material. Chitosan has many excellent properties such as biodegradability, biocompatibility, bioactivity, nontoxicity, and polycationic nature. This article reviews the discovery and preparation process of chitin and chitosan. In addition, the application of chitosan‐based films in food storage is highlighted. Finally, the future perspectives of chitosan are proposed.
