Safe coating formulated from biopolymer can be an alternative for better packaging for fruits. Among biopolymers used for safe coating, polysaccharides attracted more attention due to its biocompatibility and edibility. However, polysaccharide-based materials have weaknesses such as low water barrier and mechanical properties which result in lower capability on preserving the coated fruits. Hence, the incorporation of nanoparticles (NPs) such as zinc oxide (ZnO) is expected to increase the ability of polysaccharide-based coating for the enhancement of fruit shelf life. In this review paper, the basic information and the latest updates on the incorporation of ZnO NPs into the polysaccharide-based safe coating for fruit are presented. Various research has investigated polysaccharide-ZnO nanocomposite safe coating to prolong the shelf life of fruits. The polysaccharides used include chitosan, alginate, carrageenan, cellulose, and pectin. Overall, polysaccharide-ZnO nanocomposites can improve the shelf life of fruits by reducing weight loss, maintaining firmness, reducing the ripening process, reducing respiration, reducing the oxidation process, and inhibiting microbial growth. Finally, the challenges and potential of ZnO NPs as an active agent in the safe coating application are also discussed.

“…Reduced physical damage. [183] According to many reports in literature, silver nanoparticles (AgNPs) have already proven to be one of the most effective antimicrobial nano-based materials with a broadspectrum activity against different microbial pathogens, including bacteria, fungi, yeasts, and viruses [184][185][186]. This has made them one of the most sought-after nanomaterials in material science.…”

Food security has continued to be a topic of interest in our world due to the increasing demand for food. Many technologies have been adopted to enhance food supply and narrow the demand gap. Thus, the attempt to use nanotechnology to improve food security and increase supply has emerged due to the severe shortcomings of conventional technologies, which have made them insufficient to cater to the continuous demand for food products. Hence, nanoparticles have been identified to play a major role in areas involving food production, protection, and shelf-life extensions. Specifically, metal-based nanoparticles have been singled out to play an important role in manufacturing materials with outstanding properties, which can help increase the shelf-life of different food materials. The physicochemical and biological properties of metal-based nanoparticles, such as the large surface area and antimicrobial properties, have made them suitable and adequately useful, not just as a regular packaging material but as a functional material upon incorporation into biopolymer matrices. These, amongst many other reasons, have led to their wide synthesis and applications, even though their methods of preparation and risk evaluation remain a topic of concern. This review, therefore, briefly explores the available synthetic methods, physicochemical properties, roles, and biological properties of metal-based nanoparticles for food packaging. Furthermore, the associated limitations, alongside quality and safety considerations, of these materials were summarily explored. Although this area of research continues to garner attention, this review showed that metal-based nanoparticles possess great potential to be a leading material for food packaging if the problem of migration and toxicity can be effectively modulated.

Biofilms are a common cause of nosocomial infections that often attack hospitalized patients. The main objective of this study was to examine the efficacy of silver nanoparticles-temu giring rhizomes in combating bacteria and preventing biofilm formation. The antibacterial and antibiofilm properties of these nanoparticles were evaluated against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The research began with the extraction of temu giring rhizome, synthesis of silver nanoparticles-temu giring rhizome, disk diffusion test, biofilm formation inhibitory activity test, and characterization of silver nanoparticles-temu giring rhizome. In this research, silver nanoparticles-temu giring rhizome were utilized at concentrations of 10, 20, 40, 80, 160 μg/ml, and a control in the form of chlorhexidine. The results showed that the silver nanoparticles-temu giring rhizome produced a larger inhibition zone for bacterial growth compared to the control against the three bacteria. The IC50 value of silver nanoparticles-temu giring rhizome required to inhibit biofilm formation was 27.64 μg/ml in E. coli, 29.29 μg/ml in P. aeruginosa, and 26.21 μg/ml in S. aureus. In P. aeruginosa, E. coli, and S. aureus, the IC50 for preventing biofilm formation by silver nanoparticles-temu giring rhizome was determined to be 27.64 μg/ml, 29.29 μg/ml, and 26.21 μg/ml, respectively. Evaluation of silver nanoparticles revealed the success of temu giring rhizomes in reducing silver ions. This is shown that silver nanoparticles-temu giring rhizomes can be developed into active ingredients that inhibit the growth of bacteria that cause nosocomial infections.
