Abstract
This study presents an enzyme-gated, core-shell fibrous packaging system engineered for intelligent, on-demand salmon preservation. Utilizing coaxial electrospinning, carvacrol (CAR) was encapsulated within a zein (ZN)/gelatin (GA) matrix with a 63.94% encapsulation efficiency, producing uniform, highly hydrophobic films (water contact angle: 125.2°). The packaging functions as an "intelligent gate," where spoilage-associated bacterial proteases induce proteolytic hydrolysis of the shell, triggering the precise release of the antimicrobial payload. Mechanistically, release kinetics shifted from passive diffusion (Higuchi model) under enzyme-free conditions to an enzyme-catalyzed, first-order process at 3 U/mL protease, enhancing cumulative CAR release from 40.4% to 88.4%. In 4 °C storage trials, this dynamic responsiveness effectively inhibited bacterial proliferation and extended salmon shelf life by 2 days. This approach offers a sophisticated, targeted solution for intelligent food packaging, successfully overcoming the limitations of conventional burst-release systems.
Postharvest spoilage of fresh fruits demands efficient bio-based packaging films. Here, chitosan/gelatin (CG) films were incorporated with β-cyclodextrin-encapsulated clove essential oil microcapsules (β-CD@CEO MCs) at varying loadings. The results suggested that CEO encapsulation occurred within β-CD cavities and hydr...
Inspired by the catechol-lysine synergy and oxidative cross-linking mechanisms in mussel adhesion, we have synthesized poly-l-lysine (PLL) modified with 3,4-dihydroxyphenylacetic acid (DOPAC) to encapsulate insulin crystals. Upon oxidation, a dense, stable, and uniform membrane with nanochannels is in situ formed on th...

Improving nitrogen (N) use efficiency while reducing environmental losses remains a major challenge in agriculture. Here, we show that a single polymeric matrix based on carboxymethyl cellulose (CMC) can be effectively engineered to control urea release when structurally tailored with citric acid as a crosslinking agen...

Lauric acid (LA) is an antimicrobial medium-chain fatty acid, but its poor aqueous solubility limits its application in food matrices. To address this, ultrasound-assisted emulsion was developed using LA in vitamin E (VE) oil and chitosan-polyvinyl alcohol (CS-PVA) aqueous matrix. The emulsion exhibited uniformly dispe...

Abstract Extracts from untreated and cold atmospheric plasma (CAP)-pretreated Scutellaria baicalensis were complexed with hydroxypropyl-β-cyclodextrin (HP-β-CD) and incorporated into poly(vinyl alcohol)/chitosan (PVA/CS) electrospun nanofiber membranes for grape preservation. 1H NMR supported host–guest inclusion, wher...

Environmentally sustainable and functional food-packaging systems are increasingly being explored as platforms for the stabilization and controlled delivery of food bioactives. In this study, a multifunctional packaging film with pH-responsive properties was developed using poly(vinyl alcohol) and chitosan as the pol...
