Food spoilage caused by microbial contamination remains a global challenge, driving demand for sustainable antibacterial packaging. Conventional photocatalytic materials suffer from limited spectral response, rapid charge recombination, and insufficient reactive oxygen species (ROS) generation under visible light. Here, a Z-scheme heterojunction was constructed by coupling zeolitic imidazolate framework-8 (ZIF-8) with Ag 3 PO 4 , achieving dual-spectral absorption and spatial charge separation. The directional electron transfer from Ag 3 PO 4 ’s conduction band to ZIF-8 effectively suppresses electron-hole recombination, prolonging carrier lifetimes and amplifying ROS production (·O 2 − /·OH). Synergy with Ag + release further enhances bactericidal efficacy. Incorporated into a cellulose acetate matrix (CAM), the ZIF-8/Ag 3 PO 4 /CAM film demonstrates 99.06% antibacterial efficiency against meat surface microbiota under simulated sunlight, alongside high transparency. This study proposes a Z-scheme heterojunction strategy to maximize ROS generation efficiency and demonstrates a scalable fabrication approach for active food packaging materials, effectively targeting microbial contamination control and shelf-life prolongation.

Natural photosensitizers offer promising and sustainable solutions to the challenges of food preservation. This study investigates the potential of chlorogenic acid (CA), a naturally occurring phenolic compound with dual photoactive and antimicrobial properties. Under Xenon lamp irradiation (100 mW/cm 2 ), CA at a concentration of 0.5 mg/mL demonstrated significant antimicrobial efficacy against both Staphylococcus aureus (10 6 CFU/mL) and Escherichia coli (10 5 CFU/mL). To enhance the practical applicability of CA for cherry preservation, CA was incorporated into agar (AG) films, which exhibited superior physicochemical and mechanical properties, including increased tensile strength and improved gas permeability. Implementation of CA-AG films prolonged the storage duration of cherries by 9 days through effective quality retention and suppression of microbial contamination. This research highlights the potential of CA as an environmentally friendly and functional solution for advanced food preservation technologies.

A new generation of food packaging films is gradually replacing traditional plastic packaging films because of their biodegradability , safety, and some functional properties such as anti-bacterial and oxidant resistance. In the present work, an antibacterial packing film based on amylose starch and 2-hydroxypropyl-trimethylammonium chloride chitosan (HTCC) was prepared for meat preservation. The interfacial bonding mechanism between amylose, HTCC, and glutaraldehyde (GA) was determined experimentally and through molecular dynamics (MD) simulation. The macromolecular chains of amylose starch and HTCC became entangled via inter-molecular H-bonds and then cross-linked with GA via the Schiff base reaction. The interaction of amylose starch and HTCC improved the mechanical properties of the amylose films. Compared with the amylose films, the tensile strength and elongation at break of the optimal HTCC/amylose films reached to 16.13 MPa (an increase of 206.65 %) and 53.86 % (an increase of 109.49 %). The HTCC/amylose films were found to provide obvious bacteriostatic performance, a relatively low cytotoxicity, the lower transmittance in the UV region, and thus the ability to enhance the preservation of fresh meat. These excellent characteristics therefore suggest that HTCC/amylose films might be promising candidates for application in antibacterial food packaging films.

Foodborne illnesses remain a significant concern in the realm of public health. Managing food spoilage and controlling pathogenic microorganisms rely on synthetic chemicals, regrettably accompanied by various unfavourable attributes. In response to the escalating demand for innovative and secure alternative approaches, there has been a surge in the investigation of naturally sourced agents possessing antimicrobial characteristics, among which essential oils stand out. This study focuses on improving the stability of clove essential oil (CEO), and to achieve controlled release, the CEO microcapsules are prepared by solvent evaporation method with ethyl cellulose as the wall material. The results indicated optimum technological conditions: wall material mass fraction of 3%, core wall ratio of 1.0:1.5, emulsifier mass fraction of 8% and shear rate of 14000 r/min. Under these conditions, the encapsulation efficiency is 81.28%, and the yield rate is 90.58%. The CEOM were spherical with a size of 1.43-3.92 μm and had good thermal stability. The microcapsule under 50% ethanol showed a faster release rate and significant release amount. The microencapsulation of CEO with ethyl cellulose can not only improve the stability of CEO but also realise the controlled release of CEO, which has tremendous application value in antibacterial packaging.

Silver-metal organic framework (Ag@MOF) has exhibited outstanding antimicrobial activity in antimicrobial applications, and reducing the biotoxicity associated with silver has become a research priority. In this study, Ag@MOF was initially modified with sodium alginate (SA) to form SA-Ag@MOF. The results showed that SA could control the release of Ag + , reducing the release by about 8% at 24 h, and the biotoxicity was significantly reduced. Finally, SA-Ag@MOF was applied as an antimicrobial agent in citric acid-modified PVA film to develop a novel composite antimicrobial film. When added at 2 MIC , the CA3-M2 film can effectively inhibit the growth of E. coli and S. aureus , and the inhibition rate has reached 98%. For white radish packaging applications, CA3-M2 film inhibited the growth of surface microorganisms, while ensuring moisture and tissue hardness to extend shelf-life up to 7 days. Overall, the strategy conceived here can be a theoretical basis for novel antimicrobial packaging .

Thymol/waxy maize starch nanoemulsion (TWSN) was successfully prepared via dynamic high-pressure micro-fluidization (DHPM) and applied in pullulan-based active food packaging material (P-TWSN). The properties of TWSN and its effect on the structural and physical-chemical properties of P-TWSN were then investigated. Concurrently, the impact of TWSN (0, 5, 15, 20, 25 mL) on the storage quality and flavor substances of strawberries coated by film-forming solution (FFS) were investigated by gas chromatography-ion mobility spectrometry (GC-IMS). The results demonstrated that the prepared TWSN exhibited remarkable storage stability, maintaining a particle size of 127.9 ± 1.02 nm and a ζ-potential of −32.4 ± 0.42 mV. As TWSN concentration increased, P-TWSN exhibited a smooth and compact morphology, characterized by the presence of bubble-like pores and granular protrusions. Additionally, the FTIR peaks corresponded to the stretching vibration of -OH group of TWSN and related materials were shifted to lower wavenumbers. Furthermore, the materials with increasing content of TWSN exhibited excellent water solubility, enlarged WVP, stable thermal property and superior antibacterial capacity against gram-positive ( S.aureus ) than gram-negative ( E. coli ) bacteria. Strawberry samples sprayed by FFS with 20 mL TWSN exhibited the slowest decline in shrinkage, weight loss, titrable acidity, highest value of firmness, total soluble solids, and lower content of ascorbic acid and viable microorganisms in comparison with other dosages. Additionally, the contents of esters and alcohols in treated strawberries reached the summit on the fourth day of storage and subsequently declined, while the ketone content exhibited a downward trend with increasing TWSN, particularly in the samples with 20 and 25 mL TWSN. The studies identified an efficient method for preparing starch-based nanoemulsion by DHPM, which could be prospective in bio-active packaging materials.

Food packaging plays a vital role in guaranteeing the quality and safety of fresh products during the storage and distribution. Carboxymethyl chitosan (CMCS) is identified as a promising polymer for food packaging film owing to its film-forming ability, non-toxicity, and biodegradability. Nevertheless, the practical applications of pure CMCS film usually suffer from some limits owing to its poor antibacterial effect and mechanical strength. In this study, postbiotic-biosynthesized silver nanoparticles (AgNPs) anchored on covalent organic frameworks (COF) (namely COF-AgNP) were integrated into the CMCS film to enhance antibacterial packaging performance for preservation of fruits. Utilizing postbiotic as a reducing agent, COF-AgNPs composite nanomaterials were prepared by anchoring AgNPs on COF via in-situ reduction of Ag + . Furthermore, antibacterial packaging film was prepared using CMCS and COF-AgNPs (CMCS@COF-AgNPs) via a solution-casting method. Furthermore, characterization results proved that mechanical strength of CMCS@COF-AgNP films exhibited a gradual enhancement with the increased COFs-AgNPs content. Moreover, CMCS@COF-AgNP films exhibited an enhanced antibacterial activity and excellent biocompatibility. Importantly, CMCS@COF-AgNP coating can effectively preserve citrus quality and prolong its storage time. Therefore, CMCS@COF-AgNP films could be used as a promising and economically viable solution to diminish postharvest losses and prolong the shelf life of fresh products.

Plastic pollution and food spoilage have drawn public attention, which may cause a great threat to the global environment and human health. Therefore, natural antimicrobial packaging has a pivotal share in solving these problems. In this study, biodegradable and antibacterial packaging films were successfully prepared via incorporating self-assembled berberine-cinnamic acid nanoparticles (BC NPs) into the film matrixes. With the addition of BC NPs, the UV-shielding property, hydrophobicity, and thermal stability of packaging were apparently improved. Meanwhile, the films also held considerable mechanical property and good biocompatibility, where the migrations of films in two food simulants were all far less than the permitted limits. Furthermore, nanocomposite films (NFs) exhibited strong antibacterial ability against both E. coli and S. aureus . By measuring the fluorescence spectrum and ROS production of films, we certificated NFs were AIE-active, and the antimicrobial activity of NFs was significantly enhanced under white light. Finally, the packaging test further indicated NFs could inhibit microbial growth of chicken samples well. The sustainable NFs will be ideal candidate materials to replace plastics and extend the shelf life of food products.

The increasing prevalence of microbial contamination in the food industry has necessitated the development of advanced antimicrobial packaging materials. In this study, we developed a novel metal-organic framework (MOF)-derived nanozyme, CS/ZIF-67-Cu, synthesized through the biomimetic mineralization of chitosan (CS), followed by heterometallic hybridization. This structural configuration significantly enhanced the enzyme-mimetic activity and antimicrobial performance of the nanozymes. CS/ZIF-67-Cu efficiently generated reactive oxygen species (ROS) in situ and exhibited potent antimicrobial effects. By incorporating CS/ZIF-67-Cu into carboxymethyl cellulose (CMC), we engineered CMC@MOF composite films with enhanced antimicrobial efficacy, improved hydrophobicity, and superior UV–visible barrier properties. Preservation experiments on cherry tomatoes confirmed that the CMC@MOF films effectively inhibited microbial proliferation on the fruit surface, thereby significantly extending the shelf life. Because of its excellent biocompatibility and potent ROS-mediated antimicrobial efficacy, CS/ZIF-67-Cu has emerged as a highly efficient dual-functional nanozyme with oxidase- and peroxidase-like catalytic properties, demonstrating its potential for practical food preservation applications.

The incorporation of lemon essential oil (LEO) into cellulose nanofibrils (CNF) shows great promise in the field of sustainable antimicrobial packaging, but is challenged by poor water dispersibility of LEO and the low retention within the film. In this study, nanocellulose microgel (MG) was designed as particle stabilizers for emulsifying LEO and highly stable high internal phase Pickering emulsions (HIPE) were successfully fabricated. MG particles were constructed through chemical bonding of polyethyleneimine onto 2,2,6,6-tetramethylpiperidinyl-1-oxide (TEMPO)-oxidized nanocellulose, characterized with excellent interfacial wetting properties (reduction of oil-water interfacial tension from 11.36 to 7.84 mN/m) and antimicrobial activity (the MIC for Listeria monocytogenes was 125 μL/mL). The HIPE was obtained by dispersing LEO into MG water dispersion (0.5 wt%). The HIPE with LEO fraction as high as 75 % maintained stability within pH 5 to pH 9 without phase separation after 6 days. Films cast from HIPE and CNF blends have excellent integrity and high LEO content (38.94 %). When HIPE was added at 9.6 wt%, LEO was effectively encapsulated by CNF and MG, embedded in the film with high retention, and exhibited significant antibacterial effects against Listeria monocytogenes , antibacterial rate up to 100 %. This work, based on MG, achieves high internal phase emulsification of LEO and enhanced retention within the film, providing a novel perspective and strategy for efficient encapsulation of essential oils and their economical application in antimicrobial packaging.

Snap beans ( Phaseolus vulgaris L.) have high nutritional value but are susceptible to senescence and spoilage after harvest. Previously, a carboxymethyl cellulose/starch-based photodynamic film (CCPF) was shown to delay the senescence process and maintain the storage quality of snap bean pods (SBPs). However, the mechanism of the CCPF effect on the preservation of snap beans remains unclear. This study first confirmed the beneficial effects of CCPF packaging on the appearance and nutritional quality of SBPs and microbial growth inhibition. Then, the regulatory mechanism by which CCPF packaging impacts the physiological metabolism of postharvest SBPs was investigated via widely targeted metabolomics. The results revealed 1802 metabolites in total SBP samples, among which 464 metabolites were significantly different between SBPs packaged with the CCPF and those packaged with a pure carboxymethyl cellulose/starch-based film (CCF) in the dark. It was found that CCPF packaging could delay the deterioration of the quality of SBPs by regulating the synthesis and decomposition of phenolic acids, flavonoids, lipids, amino acids and derivatives in postharvest SBPs. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that compared with CCF packaging, CCPF packaging delayed the postharvest senescence of SBPs by affecting three potential metabolic pathways (isoflavone biosynthesis, flavonoid biosynthesis and nicotinate and nicotinamide metabolism), maintaining the storage quality of snap beans. This study revealed the possible mechanism by which CCPF packaging maintains the postharvest storage quality of snap beans.

Pullulan polysaccharide electrospun nanofiber membrane is promising in food packaging field. However, there are still some limitations in its application, due to its high hydrophilicity, poor basic properties (water and thermal stability, mechanical properties, etc.) and weak bioactivity. To solve these problems, pullulan polysaccharide was first oxidized to dialdehyde pullulan polysaccharide (DPul). Then the DPul was prepared into electrospun nanofiber membrane (DPul-M). The DPul-M was used as a green crosslinking agent, and the aldehyde group on the DPul-M and the amino group of lysozyme were reacted with each other by Schiff base to form an imine bond (C=N), thus crosslinking lysozyme to the membrane and obtaining the dialdehyde pullulan polysaccharide-lysozyme nanofiber membrane (DPul-LZ-M). After crosslinking, the basic performance of the membrane was improved and the hydrophobicity was greatly enhanced. The water contact angles can reach to a maximum angle of 108°. Meanwhile, lysozyme crosslinked on the membranes significantly enhanced the antibacterial activity of the nanofiber membrane. It can achieve the highest antibacterial rate of 95.69 % and 95.46 % against E. coli and S. aureus , respectively. The preservation test indicates that the DPul-LZ-M can extend the shelf life of blueberries. The results showed that DPul-LZ-M has good application prospects in active food packaging.
