“…Such films with good mechanical and moisture barrier properties significantly affected the shelf‐life of raw meat during 7 days of refrigerated storage by maintaining low pH value and reducing microbial count as compared to uncoated raw meat. Antibacterial action of CS coatings incorporated with ZnO nanoparticles were further assessed in guava ( Psidium guajava L.) (Arroyo et al., 2020) and tomato ( Solanum lycopersicum L.) (Alli et al., 2023). The nanostructured coatings were found to effectively inhibit the rotting of fruit, delay ripening, and improve color/firmness, thereby significantly increasing the shelf‐life of food products.…”

The inevitable drawbacks of petrochemical polymer‐based packaging (e.g., extreme loss of fossil resources, excessive products’ carbon footprint, and inordinate environmental pollution resulting from the accumulation of disposed nonbiodegradable plastic‐based packages) have urged scientists to develop novel packaging materials from nature‐inspired biopolymers. Due to their biodegradability, non‐toxicity, film‐forming ability, and barrier properties versus gasses/aroma, polysaccharides have been increasingly valued in developing food packaging materials at the lab or industrial scale. Nonetheless, these valuable biopolymers also suffer from some inherent deficiencies, that is, low resistance to water and poor mechanical attributes. Hitherto, tackling such bottlenecks via the modification of biopolymers through chemical/physical approaches and applying a combination of several biopolymers has been the main focus of numerous recent studies. In this context, the present article, for the first time, provides a comprehensive update on the most recent utilization of common polysaccharides (e.g., starch, chitosan, xanthan gum, gum Arabic, alginate, gellan, pectin, and carrageenan) for food packaging applications.

“…The humidity of the soil was maintained at ∼70% by sprinkling water twice daily. After a certain period, such as 5,10,15,20,25,30,35,40,45,50, and 55 days the samples were dug out from the soil and cleaned with 70% ethanol. The samples were dried in a hot air oven for 24 h and recorded the weight.…”

“…Similarly, chitosan is another polysaccharide-based biopolymer widely used in various applications . Chitosan is obtained by the deacetylation of chitin, which is commercially extracted from crustaceans, especially crab, prawn, and shrimp shells, whose exoskeletons are readily available as a waste derived from the food processing industry. , Chitosan, the (1–4)-2-amino-2-deoxy-β- d -glucan possesses −NH 2 on its polymeric chain, which provides unique chemical and physical properties to this biopolymer. , Both of these biopolymers possess excellent film-forming abilities. However, some drawbacks, such as low flexibility in the case of chitosan film and inferior water resistance of the alginate films, become barriers to their use in packaging applications.…”

Poor water and chemical resistance of pure biopolymeric films is a major barrier to their applications in the packaging industry. The present work involves an innovative and novel formulation of biopolymer nanocomposite utilizing a green fabrication process to produce a highly robust, chemically resistant system and printable, flexible polymeric film. This unique concept utilizes the electrostatic interaction between two biopolymeric materials (chitosan and sodium alginate) owing to their inherent functionality, which could be knowingly tuned just by changing the pH of the medium. The films are obtained from a hydrogel prepared by stepwise addition of the components as well as cross-linker in a designed manner. This is for the first time a biological alkaline extract containing carbon dots derived from banana corm (BCE CDs) is used as a cross-linker for biopolymers. In addition, mushroom was used to synthesize a nanofiber and used in the fabrication of nanocomposite film. The synthesis of lignocellulosic nanofibers from mushrooms that avoids the usage of any harmful chemicals in preparing the composite film is demonstrated. Fabricated films show tensile strengths up to ∼59 MPa after optimizing the composition. The film exhibited stability under both acidic and basic pH conditions even after being kept for 24 h. Additionally, it displayed resistance to a broad spectrum of organic solvents. In addition, the films can be used as a substrate for printing technologies, widening the scope of their use in packaging materials. Thus, the work demonstrates the fabrication of green, robust, edible, chemically resistant, and printable biobased nanocomposite flexible films.

“…Thus, the materials examined in the present study are expected to exert a caries-preventing effect. Since the nanoparticles used in this study showed aggregation of primary particles, it is necessary to consider stabilizing the particles by using a capping agent as a future investigation [56]. The gel applied to the inside of the mouthpiece must maintain its viscosity as a gel so that it can stagnate for a certain period of time and achieve a sustained effect.…”

Background: We investigated the effect of bioactive glass and zinc oxide nanoparticles on enamel remineralization, as well as their antimicrobial effect on cariogenic microbes. This is the first study that investigated the properties of bioactive glass and zinc oxide nanoparticles with mixed materials. Methods: Fluoride gel (F), bioactive glass microparticles (µB), bioactive glass nanoparticles (nB), zinc oxide nanoparticles (Z), and a mixed suspension of nB and Z (nBZ) were prepared and characterized by scanning and transmission electron microscopy, zeta potential measurement, X-ray diffraction, and acid buffering capacity testing. Further, we performed a remineralization cycle test of 28 days, and nanoindentation testing was carried out during the immersion period, and then the enamel surfaces were examined using scanning electron microscopy. Additionally, the antimicrobial effects of the sample suspensions were evaluated by measuring their minimum microbicidal concentrations against various cariogenic microbes. Results: Our results revealed that nB had a near-circular shape with an amorphous structure and a considerably large specific surface area due to nanoparticulation. Additionally, nB possessed a rapid acid buffering capacity that was comparable to that of μB. In the remineralization test, faster recovery of mechanical properties was observed on the enamel surface immersed in samples containing bioactive glass nanoparticles (nB and nBZ). After remineralization, demineralized enamel immersed in any of the samples showed a rough and porous surface structure covered with mineralized structures. Furthermore, nBZ exhibited a broad antimicrobial spectrum. Conclusions: These results demonstrated that bioactive glass and zinc oxide nanoparticles have superior demineralization-suppressing and remineralization-promoting effects.
