Summary: Biopolymers have high potential for specialized applications and creating composite materials with defined chain interactions and tailored properties is important. This study shows that glycerol and isosorbide are effective plasticizers for a chitosan-gelatin material, but isosorbide can disrupt the polyelectrolyte complexation between the biopolymers, impacting the material's glass transition temperature, mechanical properties, and water absorption. The addition of isosorbide and/or montmorillonite makes the materials hydrolytically unstable, but also affects surface hydrophilicity differently from chain structure.

Summary: A definitive screening design was used to study the effects of various factors on the functional properties of packaging films. Optimal combination conditions were identified for achieving films with desirable thickness, elongation at break, tensile strength, water vapor permeability, and opacity. Incorporation of 10.5% wt MMT in the packaging films resulted in reduced bacterial growth compared to commercial packaging. The starch films also showed biodegradability under simulated composting conditions and good handling capability during industrial production.

Summary: The current study focuses on the fabrication of polysaccharide-based films containing chitosan-pullulan blend and taro starch. The addition of taro starch was found to improve the tensile strength and crystallinity of the films, while reducing their opacity. The films with added taro starch also exhibited higher thermal stability and increased hydrophobicity. Moreover, the developed films showed antimicrobial and antioxidant properties, making them suitable for active packaging materials in the food industry.

Summary: Starch/PVA degradable straws with different PVA contents were prepared using the twin-screw extrusion method. The straws with 40% PVA exhibited the highest dispersion uniformity and molecular interactions, resulting in improved mechanical properties and water resistance. Compared to the straws without PVA, the swelling volume of the 40% PVA straws decreased significantly, and the diameter strength and water absorption were greatly increased.

Summary: To improve the performance of starch straws in thermoplastic extrusion, control straw and starch straw were prepared. The results showed that starch straws treated by rapid cooling displayed a wash-board structure with increased short-range order and crystallinities. The bending strength of starch straws cooled at -20 degrees C significantly increased, while the modulus of elasticity in bending values decreased. The water absorption of rapid cooling-treated starch straws was also lower, indicating improved hydrophobicity.

Summary: An increased interest in preparing wound healing agents based on bio-polymers has led to the development of nanocomposite films reinforced with chitosan-sodium tripolyphosphate nanoparticles. These films demonstrated improved UV-barrier property, tensile strength, and surface wettability with the addition of nanoparticles, although elongation at break was adversely affected. Overall, the incorporation of nanoparticles enhanced the antioxidant and antibacterial efficacies of the films and significantly improved wound healing outcomes in vivo.

Summary: This study investigated the deposition of gelatin-based coatings on the surface of PLA films, and the addition of phenolic acids to develop active packaging materials. The results showed that the coated PLA films had reduced moisture permeability and slight modification of thermal properties. The incorporation of phenolic acids induced structural changes in the gelatin, positively affecting the retention, diffusivity, and transfer rate of bioactive compounds in contact with the liquid simulant.

Summary: Beta-cyclodextrin and allyl isothiocyanate inclusion complexes (beta-CD:AITC) are used to develop active packaging materials for fresh fruits and vegetables. This study aimed to develop poly(lactic acid) (PLA) films loaded with beta-CD:AITC and analyze changes in material properties during the release of AITC to food simulants. Results showed that a higher concentration of beta-CD:AITC increased the absorption of aqueous simulant, while avoiding the swelling of PLA in fatty simulant. The potential of these materials for high-fat fruit and vegetable active packaging applications was suggested.
