Antimicrobial active packing has demonstrated great potential in extending food shelf life. However, developing new intelligent and responsive antimicrobial strategies is still desirable. Here, a 2-hydroxy-4-methoxybenzaldehyde (HMB)-decorated chitosan film (HDCF) via surface Schiff-base coupling is designed. HDCF shows excellent storage stability and pH-responsive release, enabling a switch in antimicrobial mode from “defense” to “attack” under acid conditions. Before HMB release, HDCF exhibits broad spectrum antifungal adhesion capabilities against Penicillium citrinum , Penicillium chrysogenum and Aspergillus niger , and antibacterial adhesion capabilities against Staphylococcus aureus . Under acidic conditions, with HMB release, HDCF displays enhanced release-antifungal performance against A. niger , P. citrinum and Candida albicans and release-antibacterial performance against S. aureus . In addition, HDCF is effective in food preservation for cherry tomatoes and tomato juice and has good UV barrier properties. Therefore, this HDCF provides a new path for diversiform antimicrobial designs in the new generation of food packaging.

Dual-functional intelligent food packaging film for maintaining and monitoring food freshness has gained a growing number of attentions in food field. Herein, we introduced a smart gelatin-based packaging film integrating real-time monitoring and maintaining food freshness. In detail, through a two-step de-solvation method, gelatin particles were fabricated and further used for preparing oil-in-water (O/W) lavender essential oil Pickering emulsions (LEOPs). LEOPs and Alizarin (ALI) were integrated into the gelatin matrix of the three-dimensional (3D) network via intermolecular hydrogen bonding and dehydration condensation, respectively, to develop intelligent active packaging films (GL-ALI-LEOPs). GL-ALI-LEOPs exhibited excellent antibacterial and antioxidant properties and a sensitive, reversible, and rapid response to pH/NH 3 . Benefiting from good mechanical properties, light barrier properties and hydrophobicity of modified gelatin-based films, GL-ALI-LEOPs are readily processed into food packaging bags and smart tags. GL-ALI-LEOPs were successfully employed as an eco-friendly, low-cost, bacteriostatic and pH/NH 3 quick-responsive smart trademark for real-timely monitoring and maintaining the freshness of shrimp.

The printed electronic technology, a simple, low-cost, and high-throughput method, exhibits great potential applications in various fields, particularly in intelligent and tamper-evident packaging. In this study, an all-printed flexible sensor is prepared for sensing tamper-evident packaging by screen printing the water-based silver nanowires (Ag NWs) conductive ink onto a polyethylene terephthalate substrate. This bendable sensor shows a corresponding variation relationship between the resistance of the Ag NWs layer and bending angles. In addition, it presents a stable resistance sensitivity at the bending angles of 45°, 90°, and 135°. The mechanisms of different printed structures on the sensitivity of the sensor have been discussed. The results show that the straight-line sensor with a linewidth of 2.0 mm has the best sensitive performance (the gauge factors at bending angles of 45°, 90°, and 135° are 37.1, 39.3, and 39, respectively). Moreover, the sensor exhibits a long-term mechanical cyclic stability (no apparent decay after 1000 bending cycles) and excellent adhesion performance (no distinct increase in resistance after 20 times). Because of the excellent sensing performance, the Ag NWs-based flexible sensor can accurately detect the opening status of the packaging, showing promising potential for practical tamper-evident applications.

A significant surge has occurred in the utilization of the active films sourced from biopolymers, which help to improve the preservation period of foods. In this study, a chitosan-quercetin (Chit-Quer) active packaging film with excellent adhesion, tensile properties, and shape memory was developed, which are conducive to enhancing the sealing and stability of packaging, and are able to adapt to complex shapes and irregular surfaces. The incorporation of quercetin resulted in a rougher and more porous structure of the Chit-Quer composite film with enhanced hydrophilicity and reduced swelling index. The addition of quercetin increased the antimicrobial activity of the composite film to over 90 %. Furthermore, both the oxidized and reduced states of quercetin significantly improved the film’s oxidative resistance. The reduced Chit-Quer film showed the strongest free radical scavenging ability, reaching 80 % within just 5 min, which was a tenfold improvement over the pure chitosan film. In addition, the Chit-Quer film can be completely degraded in about 70 days. Based on the colorimetric alteration of the Chit-Quer film in different pH environments, we further demonstrate that it can be served as an intelligent packaging film for the instant monitoring of crucian carp spoilage. These results indicate that the developed Chit-Quer film is expected to have a substantial impact in the realm of active food packaging, providing more efficient and sustainable protection for food preservation and safety.

The shelf life of cherry tomatoes is short so that new and efficient preservation techniques or procedures are required to reduce postharvest losses. This study focused on the development of a sulfonated poly ether ether ketone (SPEEK) film incorporated with amidated graphene oxide (AGO), for the storage of cherry tomatoes in modified atmosphere packaging. The mechanical properties, gas permeability, and moisture permeability were subsequently tested. The evolution of attributes related to shelf life, such as gas composition, physicochemical properties, and sensory properties were also monitored during storage trials. AGO, as an inorganic filler, increases the thermal stability and mechanical properties of SPEEK-based films, while it reduces the water absorption, swelling rate, and moisture permeability. Importantly, all the AGO/SPEEK films exhibited enhanced gas permeability and selective permeability of CO2/O2relative to the SPEEK film. Moreover, 0.9% (w/w) AGO/SPEEK film showed an enhanced permeability coefficient of CO2, corresponding to an increase of 50.7%. It could further improve the selective coefficient of CO2/O2to 67.1%. The results of preservation at 8 °C revealed that: 0.9% (w/w) AGO/SPEEK film was significantly effective at maintaining the quality and extending the shelf life of cherry tomatoes from 15 to 30 days, thereby suggesting the potential for applying AGO-incorporated SPEEK films for food packaging materials.Keywords:amidated graphene oxide;sulfonated poly ether ether ketone;modified atmosphere film;cherry tomatoes;food packaging

The mango is an important tropical fruit in the world, but it is easily perishable after harvest. In order to investigate the effect of the compound preservation technology on the physiology and quality of mangoes during transportation and storage, mangoes were treated with different packaging and preservation methods. All mangoes were subjected to simulated transportation by a vibration table for 24 h (180 r/min, 13 °C), and stored at 13 °C. The changes in the color, physicochemical characteristics, quality, and antioxidant-related enzymes of the mangoes were measured. The results show that the shelf life of inflatable bag packing (CK) was only 24 d, while the other treatments could be 30 d. The inflatable bag packing with modified atmosphere packaging (MAP) treatment (HPM) had the lowest yellowing degree (12.5%), disease index (34.4%), and mass loss (2.95%), at 30 d. Compared with the CK, the compound treatment containing MAP prolonged the peak respiration of the mangoes by 6 d and suppressed the increase in the total soluble solids and relative conductivity. Meanwhile, the HPM could effectively maintain moisture content, firmness, titratable acid, vitamin C, and the peroxidase and superoxide dismutase content, indicating that the treatment could maintain the better quality and antioxidation ability of mangoes. In summary, the MAP compound treatment better maintained the commercial characteristics of the mangoes, followed by the edible coating compound treatment. The results provide a theoretical reference for mango cushioning packaging and postharvest storage technology.Keywords:Mangifera indicaL.;simulated transport vibration;low-temperature storage;packaging method;edible coating;modified atmosphere;quality

This study aims to establish a preservation method by coupling certain barrier packaging with storage temperatures suitable for extending the shelf of chilled lamb. Chilled lamb was packaged using three different oxygen permeability packaging materials of high-oxygen-barrier packaging (HORP), medium-oxygen-barrier packaging (MORP), and low-oxygen-barrier packaging (LORP) (1.70, 23.95, and 1631.44 cm3/(m2·24·h·0.1·MPa), respectively, then stored at temperatures of 4 °C and −1 °C for 28 days, respectively. The results of total viable count, pH, color, and volatile basic nitrogen indicate that HORP effectively inhibits the growth rate of surface microorganisms and the oxidation rate of proteins in lamb. The sulfhydryl content, carbonyl value, and electronic nose suggest that the oxidative decomposition rate of lamb during storage at −1 °C is lower compared to storage conditions at 4 °C. The microbial diversity suggests that HORP significantly hinders the growth and reproduction ofPseudomonasandBrochothrixaerobic spoilage bacteria, as well as diminishes the abundance of the dominant microbial community. Herein, utilizing high-barrier packaging with an oxygen permeability of lower than 1.70 cm3/(m2·24·h·0.1·MPa) in conjunction with ice temperature storage at −1 °C is a highly effective preservation method for prolonging the shelf life of chilled lamb to 28 days.

Compared to petroleum-based plastics, paper-based materials are biodegradable and renewable, effectively easing resource overconsumption and environmental pollution issues. However, their poor water and oil repellency restricts applications in food packaging. Adding water and oil repellents can enhance paper's barrier properties, but traditional fluorine-containing coatings pose health risks like biotoxicity, accumulation, and migration, leading to global regulatory restrictions. Thus, developing green, biodegradable, bio-based water and oil repellent coatings is the future trend. In this study, taking advantage of the high reactivity of cyanuric chloride (TCT), a chitosan-derived coating (CHI-g-OA 2 ) with a double hydrophobic chain structure was successfully constructed. The formula for the preparation was optimized by the response surface method. This “molecular modification” strategy, which grafts hydrophobic oleyl alcohol chains onto chitosan molecular chains to successfully construct a hydrophobic barrier, effectively solves the problem where competitive hydrogen bonding disrupts the dense hydrogen bond network formed within and between chitosan molecules, leading to significant attenuation of barrier performance. It also achieves the synergistic improvement of the material's waterproof and oil-repellent properties while retaining the original oil and gas barrier function, which meets the standard for food packaging materials. In addition, the tensile strength of the coated paper has been increased, showing good mechanical and thermal stability.

Starch is a natural polymer material that is widely sourced, biodegradable, and non-toxic. However, the application of starch is hindered by its hydrophilicity and lack of biological activity. In this study, ε-polylysine hydrochloride (ε-PLH) was grafted onto starch for improving antibacterial properties of starch and weakening its hydrophilicity. Subsequently, a new type of active packaging film was prepared by blending polylactic acid (PLA), polybutylene adipate terephthalate (PBAT) and grafted starch (ε-PLH-g-starch) using the melt extrusion method. ε-PLH-g-starch/PLA/PBAT film can effectively inhibit Escherichia coli and Staphylococcus aureus with inhibition rates of 48.62 ± 2.43 % and 57.31 ± 1.65 %, respectively. The addition of ε-PLH-g-starch also significantly improved the tensile strength, optical properties and barrier properties of the films. As a verification experiment, the application of ε-PLH-g-starch/PLA/PBAT film can effectively inhibit the protein hydrolysis, microbial growth and fat oxidation of beef, and extend the shelf life of beef at 4 °C from 7 to 14 days.

Neoteric functional gelatin films were fabricated based on structural-colored bioactive materials and applied in practical food application. The bioactive materials could induce the excellent shear-thinning structure and benefit the spreading, leveling and thus the film forming process. From FTIR, XRD, zeta potential, SEM and AFM, the hydrogen bonding and electrostatic interaction between bioactive materials (monascus red, phycocyanin, and safflower yellow) and biopolymers, could cause the compact network structure and improve the performance of final films compared to the films without bioactive materials, including chromatic appearance, mechanical characteristics (increasing tensile strength by 625.27%, 184.10% and 296.00%, respectively), barrier properties (decreasing oxygen transmittance rates by 96.27%, 85.81% and 94.58%; and increasing light opacity by 216.56%, 54.91% and 174.04%, respectively), and antioxidant activity (increasing ABTS free radical scavenging property by 92.24%, 110.12% and 111.70%, respectively). During blueberries preservation, the functional films could effectively delay the weight losses and hardness reduction. When packaging food ingredients, functional films could be cooked together with rice and oats for obtaining excellent-looking porridge with special masticatory sensation, and have little effects on the odors (electronic-nose). Therefore, gelatin films incorporated with bioactive materials could potentially act as fresh-keeping packaging or direct eating/cooking packaging, and exhibit environmental-protective merits and recyclability, holding promises as an alternative for plastic packaging.

Microbial contamination and oxygen ingress are primary drivers of food spoilage, but advanced materials that simultaneously offer high oxygen barrier and effective antibacterial functions remain scarce. To address this dual challenge, we engineered a polyvinyl alcohol-based composite coating, incorporating the natural aggregation-induced emission photosensitizer berberine (BBR) and non-toxic layered double hydroxide nanosheets (LDH NS), on a polyethylene terephthalate substrate. The developed composite film demonstrated a low oxygen transmission rate of 0.06 cm 3 m −2 day −1 atm −1 . Furthermore, it achieved 100 % inhibition rate against both Staphylococcus aureus and Escherichia coli upon light irradiation. Crucially, we propose and elucidate a novel antimicrobial enhancement mechanism mediated by the orderly-arranged LDH NS for BBR. This mechanism involves (i) promoting BBR molecular aggregation to enhance reactive oxygen species (ROS) generation, and (ii) improving bacterial capture capacity via electrostatic interactions. These effects collectively establish a synergistic “capture–ROS enrichment–bacterial killing” pathway on the film surface. In a practical application, the composite film effectively suppressed microbial growth on packaged bread, extending its shelf life by more than 4-fold compared to conventional packaging. This work not only presents a promising multifunctional material for food preservation but also provides fundamental insights into the design of nanomaterial-enhanced, natural photosensitizer-based systems for advanced active packaging.

Novel Ce/TiO2 were synthesized using a solution-based method involving two types of Ce(III)-doped polyoxotitanium cages, namely ([Ti28O38(OEt)38CeCl(EtOH)1.4] and [Ti8O7(OEt)21Ce(EtOH)]). This novel material was used to coat the surface of polyvinylidene chloride (PVDC)/polyvinyl chloride (PVC) film, resulting in a homogeneous CeO2/TiO2@PVDC/PVC film. Remarkably, the CeO2/TiO2@PVDC/PVC film exhibited notable hydrophobicity and UV absorption capacity. Furthermore, the UV absorption capacity of the films was significantly improved with increasing CeO2/TiO2 content. The incorporation of CeO2/TiO2 also led to a substantial improvement in the barrier properties of the film, particularly in terms of water vapor permeability. These modified films hold great potential and offer a wide range of applications in the pharmaceutical packaging and food packaging industries.
