Abstract Faced with the environmental impact and non‐renewability of traditional petroleum‐based insulation materials like foamed polyethylene asbestos, this study explores sustainable, bio‐based alternatives improved thermal mechanical performance. Using Ganoderma applanatum , a mycelial growth skeleton an enhanced static air layer is constructed to optimize material's strength properties. The resulting mycelium‐based composites (MBC) achieve density 195–249 kg m −3 low conductivity 0.0370 W −1 ∙K maximum flexural 0.382 MPa, compressive 2.409 MPa. Additionally, material exhibits high water contact angle 138.6° absorption rate 44.05%–84.84%. Compared previous studies, demonstrate superior performance, striking balance between strength. These results highlight potential as eco‐friendly in packaging, construction, insulation, offering viable solution replace non‐renewable products.

Thermoplastic zein (TPZ)-based bioplastics offer a promising alternative to conventional ones. However, they exhibit certain limitations, notably in terms of mechanical strength and barrier properties. These properties can potentially be enhanced by using fillers, such as nanocellulose, produce nanocomposites. In this study, bio-based nanocomposite films were produced compression molding melt mixing approach, employing TPZ combination with two different types Silybum marianum (SM)-derived cellulose nanocrystals (SM_CNC) or nanofibers (SM_CNF), at concentrations (3 wt%-10 wt%). The effect nanocelluloses on the structure was studied means X-ray diffraction correlated mechanical, thermal physical (water permeability UV resistance) obtained TGA, DMA, spectrophotometric tests. Incorporation both nanocellulose yielded changes film properties, according filler concentration. results demonstrated that SM_CNC SM_CNF increased only 5 wt%, raising modulus 25 % 27 %, respectively. Barrier property studies revealed also improved water resistance bio-nanocomposites but lower concentration wt%) which relevant protein structural occurred. Therefore, developed possess versatile make them candidate for packaging materials foods.

Food packaging plays a crucial role in preserving freshness and prolonging shelf life worldwide. However, traditional primarily acts as passive barrier, providing limited protection against spoilage. Packaged food often deteriorates due to oxidation microbial growth, reducing its quality over time. Moreover, the majority of commercial relies on petroleum-derived polymers, which add environmental pollution since they are not biodegradable. Growing concerns sustainability have driven research into eco-friendly alternatives, particularly natural-based active solutions. Among various biopolymers, cellulose is most abundant natural polysaccharide has gained attention for biodegradability, non-toxicity, compatibility with biological systems. These qualities make it strong candidate developing sustainable materials. pure films limitations, lack antimicrobial antioxidant properties, their ability actively preserve food. To tackle this issue, researchers created cellulose-based by integrating bioactive agents properties. Recent innovations emphasize improving these through incorporation extracts, polyphenols, nanoparticles, microparticles. enhancements strengthen protective functions, leading more effective preservation. The generally classified two types: (i) blend films, where soluble substances like plant extracts polyphenols incorporated solution, (ii) composite embed nano- or micro-sized fillers within structure. addition functional components enhances efficiency while also affecting properties water resistance, vapor permeability, mechanical strength. continuous progress highlights potential viable alternative conventional innovative only extend but contribute reliance synthetic polymers. This review deals development biopolymer towards packaging.

Preserving fresh meat has been a long-standing challenge due to microbial growth and lipid oxidation. In this study, chitosan (CS) active coatings loaded with blackberry anthocyanins (BA), tea polyphenols (TP), their combination, designated as CS/BA, CS/TP, CS/BA/TP, were applied for chilled pork preservation. Compared CS coating alone, CS/BA/TP exhibited 9.3% lower total viable count (TVC), 45.5% reduction in thiobarbituric acid reactive substances (TBARS), 26.6% decrease volatile basic nitrogen (TVB-N) after 12 days of storage at 4°C. Furthermore, the combined use TP BA synergistic effect, most pronounced impact observed oxidative stability, while also improving inhibition maintaining color stability. These results highlight promising natural preservative extending shelf life.
