In this work, we prepared chitosan/eugenol-loaded IRMOF-3 nanoparticles (CS/IRMOF-3-EU) composite films using (0, 2, 4, and 6 wt%) isoreticular metal-organic framework (IRMOF-3) nanoparticles loaded with eugenol (IRMOF-3-EU), co-blended with chitosan to develop environmentally friendly food packaging materials with sustained antimicrobial activity. The microstructure and physicochemical properties of the composite films were investigated. The addition of IRMOF-3-EU to the CS matrix significantly enhanced the UV-blocking property and elongation at the break of the composite films; the CS/IRMOF-3-EU composite films inherited the antioxidant and antibacterial properties of eugenol (EU), and the DPPH radical scavenging ability was increased to 53.8% with the addition of 6% IRMOF-3-EU, while it showed excellent antibacterial ability; in addition, the CS/IRMOF-3-EU composite films achieved the sustainable release of eugenol to achieve the long-lasting antibacterial effect. Experiments on strawberry preservation applications showed that the CS/IRMOF-3-EU films slowed down the deterioration of strawberry quality, delayed the decline of hardness, effectively suppressed weight loss, H 2 O 2 content, and malondialdehyde content, and delayed the decline of catalase activity and peroxidase activity. It showed that the CS/IRMOF-3-EU composite films could be used to maintain the postharvest quality and prolong the shelf life of strawberries.

Fresh strawberries are easily contaminated by microorganisms after picking. Therefore, how to effectively store and keep fresh strawberries has been a hot topic for scientists to study. In this study, we prepared a leaf shaped metal organic framework nanomaterial loaded with quercetin (Quercetin@ZIF-L) at first, which can achieve effective loading of quercetin (96%) within 45 min and has a controlled release effect under acidic conditions. In addition, by cleverly combining satellite graphene oxide @ silver nanoparticles (GO@AgNPs) with slow precipitation performance, Quercetin@ZIF-L/GO@AgNPs nanocomposite film with larger pore size and larger specific surface area was prepared by scraping method. The characterization data of water flux , retention rate, flux recovery rate and water vapor permeability show that the composite film has good physical properties. The experiment of film packaging showed that the fresh life of strawberry could be extended from 3 to 8 days, which significantly improved the storage and freshness cycle of strawberry. At the same time, the metal migration test proved that the residual amount of silver ion in strawberry met the EU standard and zinc ions are beneficial to the health, enriching the types of high-performance fresh-keeping materials and broadening the application.

The development of safe, non-toxic, multifunctional nano preserved materials with excellent performance has become a hot research topic. Multifunctional Sophora Japonica extract (95% rutin)-derived carbon dots (R-CDs) were prepared by hydrothermal method. The π-π conjugation structure of R-CDs enabled them UV broadband absorption properties. The excellent antioxidant properties of R-CDs were attributed to the presence of the sp 2 carbon in core and a large number of hydroxyl groups at the edges, and their degradation rate of potassium permanganate and scavenging activity of superoxide anion radical were better than that of ascorbic acid . The presence of C O bond may be the site for the generation of reactive oxygen species (ROS) and thus they could kill Staphylococcus aureus ( S. aureus ), Bacillus subtilis (B. subtilis) and Listeria monocytogenes (L. monocytogenes) at a concentration of 2 mg/mL and inhibited the growth of fungi ( Botrytis cinerea ). Then R-CDs were uniformly dispersed in gelatin-based solution, and the as-prepared films had smooth surface, good hydrophilicity, strong mechanical properties and good biocompatibility. With the increase of R-CDs addition, the tensile strength increased and then decreased, and the elongation at break rose to 358%. The film inherited the broadband UV absorption, antioxidant and antibacterial properties of R-CDs. The storage period of strawberries was prolonged after coating. The variety and abundance of microorganisms on the surface of strawberries was reduced and the growth of harmful bacteria was inhibited. This work provides more possibilities for the application of nanomaterials in fruit preservation.

Biodegradable cling film is an environmentally friendly alternative to traditional plastics which still requires the addition of preservatives to improve its ability to retain freshness. Lignin, which is a natural product with both safety and antioxidant effects, has become a potential preservative. In this study, lignin was extracted from pine and corn straw by deep eutectic solvent. The lignin yield was 40.54 % and 60.60 %, respectively. A series of CS/LNPs cling films were prepared by lignin nanoparticles as the main freshness preservation and chitosan (CS) as substrates. The film with 5 % lignin nanoparticles (CS/LNPs-5) demonstrated an 89.10 % DPPH radical scavenging rate, indicating superior antioxidant capacity. Moreover, the CS/LNPs-5 films showed good UV shielding ability, mechanical properties, and hydrophobicity. Remarkably, CS/LNPs-5 was applied to preserve perishable strawberries, which extended their freshness for up to 9 days. In this study, lignin nanoparticles were successfully used to prepare cling film with high antioxidant properties, which provides a new approach for lignin in food packaging.

This study investigated the encapsulation of cinnamaldehyde with three types proteins (soy 7S, whey protein and sodium caseinate) for strawberry preservation, and illustrated the related mechanism of the sustained release ability of CA-loaded nanoemulsions from the perspective of protein-cinnamaldehyde interactions. The results of FTIR, intrinsic fluorescence, and molecular docking indicated that the dominant interactions between the protein and cinnamaldehyde were mainly hydrophobic interaction and hydrogen bonds, of which, the interaction between cinnamaldehyde and SC was the strongest with the highest binding energy. The particle size of CA-loaded nanoemulsion formed by SC was the smallest (296 nm), but its release rate of cinnamaldehyde was the slowest. These results indicated that the exchange rate of bioactive compounds in nanoemulsion with the external environment was not only affected by the size of droplets, but also strongly affected by the interaction between bioactive compounds and interfacial proteins. A slowly release rate of cinnamaldehyde represented sustained antimicrobial activity. However, in practical preservation applications, not only the type of antibacterial agent and wall material should be considered, but also the influence of the concentration of antibacterial agent released in the environment should be taken into consideration.

Utilizing biological resources facilitates alleviating energy shortage and environmental pollution problems. This work aims to develop edible packaging material that performs well and can be used for fresh fruit preservation. Tea polyphenol (TP) was successfully added to a composite-forming solution of tobacco stem cellulose (TSC) and xanthan gum (XG) to synthesize greenly the TSC/XG/TP composite film. Subsequently, the effects of TP dosage on the physicochemical and functional properties of TSC/XG/TP composite films were systematically evaluated. Results showed that the tensile strength (7.89 MPa) and elongation at break (5.27%) were maximums when the optimum TP dosage of 0.4% composite film was achieved. In addition, water vapor and oxygen barrier properties were increased by 159.57 and 7.50%, respectively, and the antioxidant activity was also enhanced by 251.59%. The composite film could maintain the strawberries’ appearance excellently and effectively inhibit color deterioration, thereby delaying postharvest decay, weight loss, and softening. It naturally follows that strawberries’ freshness is prolonged up to 14 days. Practical applications of composite films in preserving fresh strawberries have also shown positive results, making it possible as a potential food packaging material.

Perilla frutescens L. essential oil (PLEO) has antibacterial and antioxidant properties, which can effectively maintain the quality of fruits and extend their shelf life. In this study, sodium alginate and chitosan were used as wall materials, and PLEO microcapsule powder was used as the core materials to prepare PLEO hydrogel beads. The best results were obtained by using 2%w/v sodium alginate and 1.5%w/v chitosan as wall materials, with a core-to-wall ratio of 2:1 and homogenized for 15 min producing PLEO hydrogel beads with encapsulation efficiency of 82.61 %. For strawberries preservation, PLEO hydrogel beads preservation group had a better effect after 5 d of storage, showing a lower decay rate (15.71 %), better maintaining the hardness of 1.75 kg/cm 2 , and a weight loss of 3.29 %. Furthermore, organic acids and total phenols were retained more in this group, the number of microorganisms was significantly reduced, and sensory qualities were improved, especially taste and color. This study provides important insights into the application of natural preservatives in the food industry and promotes sustainable practices in food preservation.

The formation of inclusion complexes (ICs) between V-type starch and flavors is traditionally conducted in an aqueous system. In this study, limonene was solid encapsulated into V6-starch under ambient pressure (AP) and high hydrostatic pressure (HHP). The maximum loading capacity reached 639.0 mg/g after HHP treatment, and the highest encapsulation efficiency was 79.9 %. X-ray Diffraction (XRD) results showed that the ordered structure of V6-starch was ameliorated with limonene, which avoided the reduction of the space between adjacent helices within V6-starch generated by HHP treatment. Notably, HHP treatment may force molecular permeation of limonene from amorphous regions into inter-crystalline amorphous regions and crystalline regions as the Small-angle X-ray scattering (SAXS) patterns indicated, leading to better controlled-release behavior. Thermogravimetry analysis (TGA) revealed that the solid encapsulation of V-type starch improved the thermal stability of limonene. Further, the release kinetics study showed that a complex prepared with a mass ratio of 2:1 under HHP treatment sustainably released limonene over 96 h and exhibited a preferable antimicrobial effect, which could extend the shelf life of strawberries.

Developing biomass-based food packaging materials could alleviate resource scarcity and environmental pollution. This study successfully fabricated cellulose nanofibrils-based packaging films synergistically reinforced by lignin and tea polyphenols for fruit preservation. Thanks to the abundant carboxyl and hydroxyl groups in modified lignin and tea polyphenol, the composite film delivered the highest tensile strength and Young’s modulus of 230.7 MPa and 11.9 GPa, respectively. The water vapor permeability (WVP) and oxygen permeability (OP) of composite film were as low as 2.53 × 10 −11 g m −1 s −1 Pa −1 and 1.69 × 10 −16 cm m −2 s −1 Pa −1 , respectively, demonstrating excellent barrier performance. Furthermore, the composite film possessed remarkable antibacterial (100 % antibacterial activity against two types of bacteria), antioxidant (DPPH free radical scavenging activity of 90 %), and UV shielding properties (impressive UV shielding rate of 99.0 %). Strawberry preservation experiments showed that these composite films could significantly extend shelf life, owing to the excellent barrier and antimicrobial properties. Our research indicated that these composite films could be promising food packaging material compared with traditional plastic and showed great application potential in fruit preservation.

Ultrasound is a high-energy approach that can help with homogenization and dispersion in cavitation. In this study, nanoemulsions of curcumin and orange essential oil were prepared with ultrasound treatment at different times. The ultrasound-treated nanoemulsions for 10 min exhibited the smallest droplet size, the best storage, and higher thermal stability. The pullulan-based film with ultrasound-assisted nanoemulsions exhibited improved water vapor permeability and moisture content and the highest tensile strength and elongation at break. The structural analysis showed that ultrasonic treatment enhanced the H-bond, resulting in a more orderly molecular arrangement and intermolecular compatibility. Furthermore, the bioactive film had the maximum oil retention time. It possessed excellent bacteriostatic properties against Escherichia coli and Staphylococcus aureus due to the smallest oil droplets and uniform distribution in the film matrix. Besides, the weight loss and deterioration of the strawberry fruit were effectively reduced, thus prolonging the shelf life.
