“… 18 A lower WVP could reduce the moisture loss of packaged foods to the atmosphere, which was a significant factor in postharvest vegetable spoilage. 70 The WVP of the film prepared according to the optimal preparation process was 1.09 × 10 −10 g m −1 s −1 pa −1 . In a study conducted by Abdin et al , 64 they were able to decrease the WVP of the film by incorporating thymus purified extract into CMC and SA membranes (1.121 × 10 −10 g m −1 s −1 pa −1 ).…”

“…WVTR describes the amount of water transmitted through the sample per unit area of material and time [45], and WVP is an essential attribute for evaluating the moisture barrier performance of bioplastics. A bioplastic with a low WVP is desirable because it indicates that the bioplastic can limit moisture loss to the atmosphere [46]. The results show that the 5% SPT bioplastic produced the lowest average WVTR (1276 g m −2 /d) and WVP (1.86256 × 10 −7 g/ms Pa) among the SPT composites, indicating that the morphology of the material was less porous than that of the 10% and 15% SPT bioplastics.…”

Polylactic Acid (PLA) is a biodegradable polymer, but the cost of PLA is not competitive compared to polyolefins. The development of bioplastic composites by blending PLA with spent coffee grounds (SCG) and thermoplastic starch (TPS) is an effective way to reduce the cost of PLA. This study aimed to investigate and evaluate the feasibility of using SCG to develop bioplastic composite materials with a blend of PLA and TPS. Bioplastics were fabricated with various SCG contents (5, 10, 15 wt%). The physical and mechanical characteristics of the bioplastic composite decreased as the SCG content increased owing to the higher aggregation caused by SCG dust. However, the bioplastics manufactured with the addition of SCG exhibited enhanced crystallinity, resulting in enhanced thermal properties compared to the composites without SCG. The best characteristics of bioplastics, obtained with a 5% SCG addition, were as follows: water vapor transmission rate of 1276 g d/m2, water vapor permeability (WVP) of 1.86256 × 10−7 g/ms Pa, Young’s modulus of 420 MPa, elongation of 2.59%, and tensile strength of 5 MPa. Based on the results obtained, it can be concluded that the addition of SCG is not recommended for improving the physical and mechanical properties of bioplastics. However, owing to its large content of organic compounds, SCG represents a promising and low-cost functional material that can be exploited in the development of various value-added products.

“…Furthermore, curcumin exhibits hydrophobic, antioxidant, and antimicrobial properties which have the potential to further enhance the functional properties of the films, thereby expanding their applications [24]. It is worth mentioning that the addition of these natural extracts has an effect on the water vapor permeability (WVP) of nanofibers; this effect is not dependent on the hydrophobicity of the natural extracts themselves; rather, it is also related to the nanofiber substrate and interactions [25]. For example, hydrophobic curcumin increases the WVP of cellulose/chitin nanofibers, whereas water-soluble anthocyanins decrease the WVP of pullulan/polyvinyl alcohol nanofibers [26,27].…”

Due to the growing concerns surrounding microbial contamination and food safety, there has been a surge of interest in fabricating novel food packaging with highly efficient antibacterial activity. Herein, we describe novel photodynamic antibacterial konjac glucomannan (KGM)/polyvinylpyrrolidone (PVP) nanofibers incorporated with lignin-zinc oxide composite nanoparticles (L-ZnONPs) and curcumin (Cur) via electrospinning technology. The resulting KGM/PVP/Cur/L-ZnONPs nanofibers exhibited favorable hydrophobic properties (water contact angle: 118.1°), thermal stability, and flexibility (elongation at break: 241.9%). Notably, the inclusion of L-ZnONPs and Cur endowed the nanofibers with remarkable antioxidant (ABTS radical scavenging activity: 98.1%) and photodynamic antimicrobial properties, demonstrating enhanced inhibitory effect against both Staphylococcus aureus (inhibition: 12.4 mm) and Escherichia coli (12.1 mm). As a proof-of-concept study, we evaluated the feasibility of applying nanofibers to fresh strawberries, and the findings demonstrated that our nanofibers could delay strawberry spoilage and inhibit microbial growth. This photodynamic antimicrobial approach holds promise for design of highly efficient antibacterial food packaging, thereby contributing to enhanced food safety and quality assurance.
