“…The WVP value can be affected by the structural properties of the polymer components, the type and concentration of additives, and hydrophobic/hydrophilic behaviour (Ahari et al ., 2022). Table 1 shows the physical properties of gelatin–polyvinyl alcohol blends containing Cinnamomum zeylanicum extract in various percentages.…”

SummaryThe effects of Cinnamomum zeylanicum extract (CZE) at different rations (0%, 1%, 3% and 5%) on gelatin (GL)–polyvinyl alcohol (PVA) blend films were evaluated in relation to the structural, tensile strength, physical, antimicrobial and antioxidant properties of the films in this study. The results showed that water barriers of the film samples decreased, but the UV‐blocking property increased and became opaque at the highest GLPVA5 film. The tensile strengths of GLPVA, GLPVA1, GLPVA3 and GLPVA5 films were 1.21, 1.78, 1.62 and 1.95 MPa, respectively. The antimicrobial effect of these films was determined against Escherichia coli, Enterococcus faecalis, Salmonella typhimurium and Bacillus cereus according to the parallel stick method. Antioxidant properties of cinnamon extract were investigated using 2,2‐diphenyl‐1‐picryl‐hydrazil (DPPH) methods. The % inhibition of DPPH was found to be 82.00. No antibacterial effect was detected for B.cereus and E. faecalis at 0%, 1%, 3% and 5%. While no activity was observed in 0%, 1% and 3% cinnamon, 7.5 and 3.0 mm zones were detected in S. typhimirium and E. coli, respectively, in 5% cinnamon. The results suggest that the film samples could be used in a potential packaging with antioxidant and antibacterial properties.

Considering the ecological and environmental issues caused by petroleum-based plastics for packaging fresh-cut fruits and vegetables (FFVs), there is an urgent need to develop sustainable and ecofriendly active packaging. Therefore, marine-derived biodegradable carboxymethyl chitosan (CMC) and sodium alginate (SA) were used to construct a layer-by-layer assembly system. Then, graphene oxide (GO) was introduced into the SA layer to produce (CMC/SA) n @GO x composite films. The impacts of the GO content (x) and assembly layers (n) were investigated on the internal interactions, microstructure, and packaging properties of the multilayer films. The rise of x and n leads to the increase of the microregion size and interface thickness in the films, and the introduction of GO into the SA layer enhanced its attraction to the CMC layer. With variations in both x and n, the (CMC/SA)19@GO5 film exhibited the greatest mechanical and barrier properties, along with enhanced UV-shielding capacity. Based on the above result, three different (CMC/SA) n @GO x films were selected for fresh-cut apple packaging, with transcriptomics used to investigate preservation mechanisms. The results showed that the (CMC/SA)19@GO5 packaging performed with the best physiological quality due to its high barrier properties, resulting in lower weight loss, reduced browning, and improved hardness. This was attributed to enhanced antioxidant capacity and resistance to wounding stress as well as delayed cell wall degradation and terpenoid biosynthesis, extending the shelf life of fresh-cut apples. In conclusion, this study demonstrated the potential of green packaging based on marine biopolymers for FFV preservation.

Biodegradable packaging plastics combining good mechanical properties and low gas permeability is required to avoid environmental and food safety concerns. This study explores the impact of montmorillonite (MMT) and halloysite nanotubes (HNT), on the mechanical, optical, and oxygen permeability of blown film poly (butylene adipate‐co‐terephthalate) (PBAT) composites. The morphology of the films was evaluated by x‐ray diffraction (XRD), differential scanning calorimetry and scanning electron microscopy. Good distribution/dispersion of clays is found in the PBAT‐MMT films. Besides, there is an increase in the crystallinity of PBAT due to the nucleating effect of HNT. Improvement in the tensile strength and elongation at break in the machine direction is obtained up to a clay content of 1.5 vol%. The incorporation of 1.5 vol% of MMT and 1 vol% of HNT leads to a reduction in the oxygen permeability of the PBAT film by 29% and 38% respectively. Furthermore, the films remain transparent regardless of clay content. Finally, the feasibility of the films for food storage is tested in grapes, obtaining extended shelf life. The favorable mechanical, barrier and optical properties of the biodegradable films, along with the scalable production process, make them attractive for application in the storage and preservation of food products.
