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.

Developing environmentally friendly film materials for packaging pesticides is significant yet challenging. The use of native starch for preparing inner packaging materials of pesticides is limited by its physicochemical properties. In this study, a novel strategy of synergetic mechanical activation (MA)-enhanced solid-phase esterification of starch and cooperative combination of starch and polyvinyl alcohol (PVA) was proposed to fabricate biodegradable and cold-water-soluble starch (St)/PVA films. The appropriate esterification of starch and favorable compatibility between starch and PVA contributed to the production of St/PVA films by the extrusion-blowing method. The as-prepared film with St/PVA ratio of 4:6 exhibited outstanding mechanical properties (tensile strengths of 21.0 MPa; elongation at break of 213.9 %), cold-water solubility (dissolution time of 90 s), and oxygen barrier performance (oxygen transmission rate of 1.41 cm 3 /(m 2 ·day·bar)). The dissolved St/PVA films with amphiphilic groups were conducive to the emulsification of butachlor (a fat-soluble liquid pesticide) and the dispersibility of oxyfluorfen (a fat-soluble solid pesticide). Furthermore, a mechanism of the interaction between pesticides and the surface of weed leaves was proposed to reveal the enhanced efficacy of St/PVA films-packaged pesticides. The strategy based on MA-enhanced esterification and PVA blending is efficient to produce starch-based films suitable for inner packaging materials of pesticides.

BACKGROUND There has been limited research on the use of ZnO nanoparticle-coated film for the quality preservation of pork meat under low temperature. In the present study, ZnO nanoparticles were mixed with sodium carboxymethyl cellulose (CMC-Na) to form a nanocomposite film, to investigate the effect of ZnO nanoparticle-coated film on pork meat quality and the growth of bacteria during storage under low temperature. RESULTS When ZnO nanoparticle-coated film was used as the packaging material for pork meat for 14 days of cold storage at 4 °C, the results demonstrated a significant effect on restricting the increases in total volatile basic nitrogen and pH levels, limiting the decreases of lightness (increased L * value) and redness (increased a * value), and maintaining the water-holding capacity compared to the control pork samples ( P < 0.05). The present study also discovered that the ZnO nanoparticle-coated film restrained the increase in total plate count (TPC). When Staphylococcus aureus was used as the representative strain, scanning electron microscopy revealed that ZnO nanoparticles increased the occurrence of cell membrane rupture under cold conditions. CONCLUSION ZnO nanoparticle-coated film helps retain the quality of pork meat during cold storage by increasing the occurrence of microorganism injury. © 2016 Society of Chemical Industry

Using chitosan and polyvinyl alcohol (PVA) as substrates, active packaging composite (VPC) films based on vanillin-crosslinked PVA/chitosan with different concentrations of added vanillin were prepared and characterized. The results show that the VPC films exhibited higher tightness and hydrophobicity, lower water content and water vapor permeability, as well as better UV resistance. The potential interactions between the film groups were analyzed by SEM, FTIR, and XRD, and the results showed that the formation of Schiff base and hydrogen bond interactions affected the properties of the films. The VPC films also showed excellent antioxidant activity. Therefore, vanillin-crosslinked PVA/chitosan active films have broader application prospects as packaging materials for food preservation.

It was focused on development a film with excellent properties. The pectin/sodium alginate (PS) composite films were developed by a casting technology, incorporating with tannic acid and Fe 3+ for double cross-linking, and the effects of the film thickness, optical, mechanical, barrier, and antioxidant properties were investigated. This results displayed the inclusion of tannic acid (TA) and Fe 3+ considerably increased the physical aspects, and they were very compatible with the matrix of the PS, exhibiting higher UV barrier capacity and lower gas permeability . On the other hand, the more compact structure observed by SEM as well as the hydrogen bonding interactions between the film components revealed by FTIR spectroscopy and XRD diffraction analyses further confirmed the significant enhancement of the properties. The functionalized coating of TA-Fe 3+ demonstrated an improved adhesion and barrier properties, thereby effectively retarding the ageing process of golden passion fruit and this encompassed a decrease in the weight loss and a significant enhancement in water retention capability.

Ethylene-induced quality deterioration of postharvest fruits aggravates food wastage worldwide, therefore, the development of effective approaches for reducing ethylene concentration of packaged fruits is of paramount importance in extending shelf life and minimizing food spoilage . In this work, a modified HKUST-1 (i.e., HKUST-1-P) was added to a chitosan quaternary ammonium salt (CQAS)-gelatin matrix to prepare a food packaging film (i.e., HPCGF) with ethylene adsorption property and improved water stability. Molecular simulation revealed that the ethylene preferentially bonds to the C and O sites of HKUST-1, followed by the H and Cu sites to achieve adsorption. The physical adsorption performance of HKUST-1 and HKUST-1-P was 89.91 and 89.05 cm 3 /g STP, respectively. Moreover, HPCGF showed improved physicochemical (e.g., thermal stability, mechanical, and gas barriers) properties that are beneficial for food packaging. As a validation experiment, the effectiveness of HPCGF for preserving a climacteric fruit (banana) was demonstrated by absorpting the ethylene, maintaining the color and hardness, delaying lipid peroxidation , and prolonging shelf life of bananas. This study will aid in the development of novel packaging materials with ethylene adsorption properties for preserving perishable foods, helping reduce food waste.

This study focuses on enhancing the antibacterial and self-cleaning properties of bio-based food packaging films. We developed a zwitterionic rosin sulfonated betaine (MPA-BN + SO 3 − ) and co-grafted it with rosin quaternary ammonium salt onto chitosan, which was then combined with gelatin to create the films. Characterization was done using FTIR and 1 H NMR. The films exhibited a minimum inhibitory concentration (MIC) of 200 μg/mL for Staphylococcus aureus and 400 μg/mL for Escherichia coli , with a 19 mm antibacterial zone for 30% CS-B-S in Staphylococcus aureus . The modification improved water solubility, tensile strength (10.22 MPa, a 20% increase), elongation at break (87%), and antioxidant properties (48.2%). Preservation tests on fresh fruits and biological safety assessments through cytotoxicity tests and a 30-day gastric lavage experiment in mice confirmed the effectiveness and safety of films. Outdoor degradation tests showed strong biodegradability and minimal environmental impact. These results suggest that the CS-B-S/gelatin film is a promising food packaging material with excellent antibacterial, antifouling, and biodegradable properties.

An antibacterial film based on Chinese yam starch (D-sorbitol as plasticizer) incorporated with eugenol (YDE) was prepared for pork preservation. The structure of films was characterized and the evaluation of two plasticizers (glycerol and D-sorbitol) on their mechanical and barrier properties was performed to determine the vehicle of eugenol. The release behavior and antimicrobial activity of YDE were investigated and the application of the films for pork preservation was evaluated. The mechanical and barrier properties of films were dependent on plasticizer. The release of eugenol from films was well-controlled by two release mechanisms of diffusion and erosion. YDE displayed good eugenol dose-dependent antibacterial activity which was higher against E. coli than against L. monocytogenes and S. aureus . The film with 3% eugenol can extend the shelf-life of pork beyond 50%, suggesting that the film may have great potential in active packaging for extending the shelf-life of foodstuffs.

Using biodegradable material derived from renewable resources as petroleum-based plastics replacement is a promising way towards sustainable development. However, the insufficient mechanical properties and complex manufacturing process of bioplastics still need to be improved for high-quality food packages. Herein, we report a top-down strategy to transform natural wood into a clear wood packaging film through scalable delignification and polyvinyl alcohol (PVA) infiltration. The wood packaging film demonstrates a laminated structure with completely collapsed cell walls and PVA intertwined together after energy-saving air drying, resulting in high light transmittance with low haze, good mechanical performance, and high barrier performance for oxygen and water vapor. Molecular dynamics simulations reveal the underlying fracture mechanism between cellulose and PVA, which effectively enhances the Young’s modulus and strength of the wood packaging film. These findings contribute to the development of biodegradable and strong packaging materials, as well as other food-related applications, using sustainable wood.

In this study, a multi-functional packaging film was fabricated, utilizing the natural polysaccharide chitosan (CS) as the base material, integrating natural blueberry anthocyanin (AN) as pH-responsive indicator, and reinforced with cellulose nanocrystals (CNCs). The implications of addition levels of CNCs on the characteristics of the films were systematically investigated, resulting in that CS-AN-CNCs 9 % film exhibited optimal performance. Specifically, the film showed a substantial enhancement in maximum tensile strength from 15 MPa to 35 MPa; On the other hand, the swelling degree properties, the oxygen permeability and water vapor permeability decreased from 159.2 % to 92.0 %, from 51.7 g/(m 2 d) to 12.2 g/(m 2 d), from 31.6 × 10 −12 g/(m·s·Pa) to 1.6 × 10 −12 g/(m·s·Pa), respectively. Moreover, the CS-AN-CNCs 9 % film exhibited antioxidant, antibacterial, coupled with a color metrically responsive to pH variations, displaying great potential in indicating the shrimp freshness and delaying spoilage. Another notable advantage of the-prepared packaging material lies in its completely biodegradability, therefore meeting the requirement of environmental protection. Therefore, the prepared CS-AN-CNCs film as an intelligent packaging solution with potential applications in food preservation and freshness monitoring applications.

Most traditional food packaging and preservation films suffer from limited stretchability and relatively simple functionality, which severely restricts their practical application. In this study, a highly stretchable and versatile sodium carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA)/poly(ethylene imine) (PEI)/tannic acid (TA) hydrogel film was elaborately designed and demonstrated as an efficient food packaging and preservation system. The dynamic reversible non-covalent within three-dimensional (3D) network structures served as sacrificial bonds to dissipate the loaded energy and endowed the hydrogel film with excellent elongation ~400 %, which is much larger than that of conventional food packaging films (<50 %). Furthermore, the optimized CMC/PVA/PEI/TA 3 hydrogel film delivers versatile performances, including self-healing, whole UV-blocking (<400 nm), strong adhesive strength (234.08 KPa), antioxidation virtues, oxygen barrier (32.64 cm 3 *μm/(m 2 *d*KPa)) and water vapor barrier (642.92 g/(m 2 *24 h)). Notably, the shelf life of fresh strawberries, mangoes, and cherries was prolonged by at least one week under ambient conditions when the packaging box was covered by the fabricated CMC/PVA/PEI/TA 3 film. Thus, our work not only provides a highly stretchable and versatile hydrogel film but also boosts the in-depth comprehension and rational design of robust food packaging and preservation films.
