Sustained-Release Chitosan/Gelatin Active Packaging Films Incorporating Quercetin-Loaded Zeolitic Imidazolate Framework-8 for Cherry Tomato and Grape Preservation

Chitosan-polyvinyl alcohol hydrogel films containing polyphenols-encapsulated ZIF-8 for pH-responsive freshness monitoring and preservation of pork.

We developed a biodegradable hydrogel-based packaging film from chitosan and polyvinyl alcohol. The film was integrated with epigallocatechin gallate, curcumin, or anthocyanins encapsulated in zeolitic imidazolate framework-8. Due to the synergistic effects between ZIF-8 and polyphenols, the films had enhanced mechanic...

Nanomaterial-reinforced biodegradable guar gum/gelatin composite films for shelf-life extension of perishable fruits.

Perishable fruits have a short shelf life due to their susceptibility to quality deterioration after harvest. Implementing appropriate preservation measures is an effective strategy to maintain fruit quality and enhance market value. However, traditional polyethylene films not only offer limited functionality but also...

Electrostatically self-assembled ternary nanoparticles loaded with sesamol reinforce gelatin/chitosan films with enhanced physicochemical properties for fresh-cut apple and banana preservation.

pH-driven electrostatic self-assembly was used to fabricate sesamol-loaded whey protein isolate/pectin (WPI) nanoparticles, which were incorporated into gelatin/chitosan (GC) films to improve their gas barrier and antioxidant properties for fruit preservation. The highest encapsulation efficiency (77.1%) was obtained a...

In-situ incorporation of zeolitic imidazolate framework nanoparticles into the carboxymethylcellulose/alginate hydrogel film: a potential antibacterial bio-platform for wound dressing

Curcumin-loaded carboxymethyl cellulose/sodium alginate films with enhanced solubility and bioactivity for freshness monitoring of fish and beef.

Intelligent active food packaging films were developed by enhancing curcumin solubility through 2-hydroxypropyl-β-cyclodextrin inclusion complexes (EC). EC was incorporated at varying concentrations into a carboxymethyl cellulose (CMC)‑sodium alginate (SA) matrix. Sedimentation tests revealed that free curcumin exhibit...

Corn Starch-Based Bio-Composite Films Reinforced with Sunflower Seed Hull Powder and Thyme Essential Oil: Enhanced Mechanical, Antioxidant, and Antibacterial Performance for Sustainable Active Food Packaging

Engineering biodegradable sheets with inherent bioactivity is a crucial advancement for next-generation active packaging systems. Corn starch-based bio-composite films were enhanced with sunflower seed hull (SSH) powder as a phenolic-rich reinforcement, glycerol as plasticizer, vinegar as an acidic formulation ingredie...
