Cross-linked Gelatin/oxidized Sodium alginate/ε-polylysine/tea Polyphenol Active Packaging Film with Excellent Antimicrobial and Antioxidant Activities for Dried Tofu Preservation

Development of natural organic acid cross-linked PVA/starch films with enhanced physicochemical and antioxidant properties for extending the shelf life of Malus domestica

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...

Development of Dual Enzymatic–Ionic Crosslinked Alginate–Gelatin Films Enriched with Pelargonium sidoides Extract for Active Packaging and Anthocyanin Preservation in Flame Seedless Grapes

Active biodegradable packaging materials capable of preserving fruit quality and reducing oxidative processes are promising alternatives to conventional petroleum-based plastics. In this study, alginate–gelatin composite films were developed using a dual crosslinking strategy combining microbial transglutaminase-mediat...

Preparation and properties of hydrophobic soy protein isolate/carboxymethyl cellulose/gelatin composite films via phytic acid-induced dual crosslinking.

In this study, phytic acid (PA) was employed as a multifunctional crosslinking agent to fabricate dual-crosslinked composite films based on soy protein isolate (SPI) and carboxymethyl cellulose (CMC), with glycerol as a plasticizer and gelatin as a processing aid to improve film flexibility and processability, thereby...

Barium Crosslinking in Bio‐Based Sodium Alginate Films: Improved Barrier and Thermal Performance Toward Biodegradable Packaging Applications

Growing environmental concerns associated with petroleum‐based plastics have intensified the demand for sustainable, biodegradable materials for packaging applications. Sodium alginate is a natural polysaccharide with excellent biodegradability, biocompatibility, and film‐forming ability; however, its high moisture...

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...
