Modified Atmosphere Packaging (MAP) technology holds significant potential for preserving fruits and vegetables. In this study, we explored a novel MAP gas regulation technology that regulates selective gas permeation and achieves gas equilibrium within the package. Inspired by natural leaf stomata that regulate plant respiration, we fabricated polyethyleneimine-modified porous chitosan microspheres (PEI-PCM) that mimic the function of stomatal ‘switches’ in order to enhance respiratory regulation. And PEI-PCM were introduced into the gelatin-tannic acid (GT) film to construct a biomimetic porous chitosan microsphere-composite gelatin-based film (GT@PEI-PCM, GTPP) for the preservation of perishable fruits (litchi and waxberry). GTPP film can control and regulate gas exchange driven by CO 2 concentration levels, achieving atmospheric equilibrium within 24 h and preventing oxidative damage to fruits. In addition, GTPP films demonstrated excellent tensile strength as well as water resistance, antibacterial, and antioxidant properties. The incorporation of modified microspheres could regulate the gas permeability and selectivity (CO 2 /O 2 : 0.79–2.53) of the gelatin-based films, which successfully prolonged the freshness of litchis and waxberries. Overall, this innovative gas permeation control strategy provides a novel concept for improving MAP technology.

Postharvest preservation urgently demands innovative solutions bridging atomic precision with practical scalability. Here, a distinctive photocatalysis-driven self-assembly strategy is presented that fundamentally diverged from conventional high-temperature syntheses by enabling precise single-atom coordination under ambient conditions. This approach, utilizing α-lipoic acid (α-LA) as coordination ligand, achieved the mild assembly of S-coordinated Cu single-atom nanozymes (Cu/CNS) while significantly enhancing their enzymatic activity. The resulting material demonstrated unprecedented multi-enzyme mimetic activities (catalase-, oxidase-, and glutathione oxidase-like) with catalytic efficiency surpassing conventional nanozymes by orders of magnitude. The Cu/CNS exhibits near-perfect antimicrobial efficacy against Escherichia coli ( E. coli ), Staphylococcus aureus ( S. aureus ), and Botrytis cinerea ( B. cinerea ) through synergistic mechanisms. When integrated into chitosan-gelatin films (Cu/CNS@CS-Gel), it forms active packaging with pH-responsive behavior, exceptional barrier properties, and mechanical strength. Crucially, the synthesis is simple, scalable, and environmentally adaptable. Using strawberries and kiwifruits as representative examples, Cu/CNS@CS-Gel more than doubled the shelf life while efficiently maintaining nutritional quality. Beyond food packaging, this coordination chemistry platform is generalizable to other metal-ligand systems, offering a versatile toolbox for sustainable agriculture. By bridging atomic-level design with practical feasibility, the work advances sustainable nanozyme implementation in food systems.

Ultrasound-assisted extraction (UAE) of total anthocyanin (TA) and total phenolics (TP) from Rubia sylvatica Nakai fruit (RSF) was optimized using response surface methodology. On the basis of a single-factor experiment, six factors were screened using a Plackett-Burman experimental design to determine the variables that significantly influence the extraction yield of TA and TP, namely ultrasound power, liquid: solid ratio, ethanol concentration, pH value, extraction temperature, and extraction duration. Based on statistical significance analysis, ethanol concentration, pH value, and extraction temperature were selected for further optimization of the extraction process using a Box–Behnken design. Under the optimum conditions, yields of TA and TP were 22.50 ± 0.89 mg cyanidin-3-glucoside/g RSF and 36.20 ± 0.11 mg gallic acid/g RSF, respectively. The extract prepared under UAE exhibited excellent DPPH radical scavenging activity (IC 50 1.21 ± 0.04 mg/mL). The results demonstrate that R. sylvatica fruit are rich in anthocyanins and show considerable potential as a source of colorants for use in the food industry.

Methyl parathion (MP), an organophosphorus pesticide, exhibits potent insecticidal activity. However, the high toxicity of MP residues poses a serious threat to the environment and food safety. To achieve highly sensitive detection of MP, an electrochemical sensor was developed utilizing a composite modifier comprising multi-walled carbon nanotubes (MWCNTs), zirconia (ZrO 2 ), and curcumin (CM). MWCNTs provide a three-dimensional interconnected carbon conductive network. Owing to their inherent high electrical conductivity and large specific surface area (derived from their one-dimensional hollow nanostructure), this network accelerates electron and ion transport. ZrO 2 nanoparticles exhibit specific affinity for phosphorus-containing functionalities (including P S) within MP molecules, promoting analyte enrichment; the electropolymerized curcumin forms a redox-active mediator layer that facilitates MP reduction. This synergistic combination results in superior sensing performance. Under optimized conditions, the developed MWCNTs@ZrO 2 /CM sensor exhibits a linear detection range for MP from 0.01 to 10 μM and achieves a limit of detection (LOD) of 7.13 nM (S/N = 3). The fabricated sensor demonstrated excellent repeatability and reproducibility. Moreover, the sensor displayed high accuracy and practicality for MP determination in real fruit juice samples, underscoring its potential for food safety monitoring.

In the present study, the biocontrol efficacy of Metschnikowia pulcherrima E1 against grey spot rot ( Pestalotiopsis vismiae ) on loquat fruits was assessed and along with potential mechanisms of action. Results indicated that decay incidence and lesion diameter were both significantly reduced by treatment of fruits with the yeast, M. pulcherrima E1. M. pulcherrima E1 quickly colonized wounds in loquat fruit stored at either 20 °C or 4 °C. Scanning electron microscopy revealed that the yeast formed a biofilm on the wound surface in loquat fruit which inhibited the invasion of pathogenic fungi. M. pulcherrima E1 also competed with the pathogen for nutrients (iron) and space. Results of dual-culture petri dish assay indicated that M. pulcherrima E1 produces volatile antifungal compounds that inhibit the growth of P. vismiae. SPME-GC–MS analysis revealed that 3-methyl-1-butanol, phenylethyl alcohol and 1-Hexanol are the main volatile organic compounds produced by M. pulcherrima E1 and that had a significant inhibitory effect on the growth of fungal mycelia. M. pulcherrima E1 induced a higher level of defense-related enzyme activity in loquat fruit, including polyphenol oxidase, peroxidase, catalase, ascorbate peroxidase, and phenylalanine ammonia-lyase. Collectively, the results of the present study indicate that M. pulc herrima E1 has good potential to be used as a biocontrol agent against postharvest grey spot rot on loquats. The different mechanisms of action exhibited by M. pulcherrima E1 enhances its ability to control P. vismiae .

This study was to investigate the effects of different nonthermal treatments on quality attributes, anthocyanin profiles, and gene expressions related to anthocyanin biosynthesis during low-temperature storage, including pulsed light (PL), magnetic energy (ME), and ultrasound (US). Among these treatments, 1 min US treatment was the most effective method for improving fruit quality and increasing total anthocyanin contents (by 29.89 ± 3.32%) as well as individual anthocyanins during low-temperature storage of 28 days. This treatment resulted in high color intensity, intact cellular architectures, and positive sensory evaluation. In contrast, PL and ME treatments displayed negative effects on quality improvement, leading to the destruction of cell architectures and inhibiting anthocyanin levels. Furthermore, qPCR analysis revealed that the structural genes (C4H, CHS1, CHS2, CHI, F3H, ANS, and GST) related to anthocyanin biosynthesis and transport were the target genes and upregulated in response to the cavitation effect of US treatment.

The univoltine Bactrocera minax (Enderlein) is a devastating pest of citrus in Nepal, India, Bhutan, and China. To better understand the overwintering pupal diapause, we investigated the juvenile hormone III (JH III) and ecdysteroid 20-hydroxyecdysone (20E) titers across the developmental stages, and the effects of juvenile hormone analog (JHA) and 20E treatments on adult emergence patterns. The results showed that both JH III and 20E levels fluctuated from the late larval stage to the late pupal stage. JHA and 20E treatments at the late larval stage had marginal effect on the adult emergence patterns, with slightly faster adult eclosion and higher eclosion rate. Similarly, JHA treatment at the early pupal stage did not affect the adult emergence. However, 20E treatment at the early pupal stage remarkably shortened the duration of diapause, but lowered the eclosion rate, especially with relatively high dose. These findings demonstrated that 20E treatment at the early pupal stage is a suitable method to hasten the diapause termination of B. minax, which will contribute to the rearing of B. minax in the laboratory as needed for routine experiments.

The inherent diversity in chemical composition and microstructure of fruit wax and cuticle layers serves as a core barrier to the universal adhesion of conventional coatings on a range of fruit surfaces ( e . g ., blueberry and grape). Herein, calcium ions were introduced into chitosan-gallic acid (CS-GA) to develop a metal-phenolic networks (MPNs) modified CS coating, which was named CS-GA-Ca. According to microstructural characterization, calcium ions, as a crosslinker, form a coordination with catechol in copolymers and further reconstruct a H-bonding network, resulting in smaller molecular chain spacing and a tighter polysaccharide network structure. Furthermore, the CS-GA-Ca films demonstrated improved vapor barrier and mechanical properties. The CS-GA-Ca coating exhibited improved adhesive capacity on the wax layer of blueberries. The molecular dynamic (MD) stimulation results revealed stronger Van der Waals forces (-64.35 kcal·mol −1 ) and electrostatic interactions binding energies (-28.84 kcal·mol −1 ) between CS-GA-Ca and epicuticular wax components compared to CS-GA (-4.21/0.01 kcal·mol −1 ). Finally, the CS-GA-Ca reduced weigh loss of blueberries and grapes by 17% and 27% compared to uncoated ones over 24 days (4℃) and 10 days (25℃), respectively. Moreover, the blueberries and grapes coated with CS-GA-Ca exhibited 2.0-fold and 1.6-fold prolonged shelf life compared to uncoated ones, respectively. Overall, this study presents a promising approach for developing bio-derived coating materials to prolong the shelf life of fruits.

The proliferation of single-use petroleum-based foams in protective packaging has become a major source of persistent plastic waste, posing significant challenges to environmental sustainability. To address this issue, we developed a fully biodegradable cushioning foam from bamboo, a rapidly renewable biomass, using an environmentally benign deep eutectic solvent (DES) process that avoids harsh chemical bleaching. The resulting lignin-containing cellulose nanofibril (LCNF)/sodium alginate (SA) foam exhibits low density (0.23 g/cm3), high compressive strength (0.24 MPa at 70% strain), and excellent elasticity (90% recovery at 50% strain), enabled by a dual-network structure of Ca2+-crosslinked SA and entangled LCNFs. Critically, the material is fully compostable and leaves no microplastic residues, offering a circular end-of-life pathway. In real-world banana drop tests, it matched the performance of commercial expanded polyethylene (EPE) while outperforming polyethylene bubble wrap. This work demonstrates a practical, scalable route to replace fossil-derived cushioning materials with a bio-based alternative that aligns with the principles of cleaner production and circular economy.

We present an enzyme-free glucose sensor for on-site fruit testing based on a Ni-doped triblock hydrogel that couples ionic-channel conduction with hydrogen-bond–reinforced mechanics. In the hydrogel, the NiCl 2 -hydrogel (Ni-HG) pair generates continuous ion pathways that enhance charge transport, while phytic acid establishes multi-point hydrogen bonding and moisture retention, yielding a robust, highly adhesive network that conforms to diverse electrode formats. Within this hydrated, ion-permeable scaffold, Ni 2 + /Ni 3+ (Ni(OH) 2 /NiOOH) functions as a built-in redox mediator, enabling selective, enzyme-free oxidation of glucose in alkaline media. Under optimized conditions, the Ni-HG/GCE sensor delivers a broad linear range of 0.05–6.6 mM, limit detection of 10 μM, with high selectivity against common electroactive species, good repeatability, and reliable performance in real fruit samples. The hydrogel architecture supports rapid amperometric response and stable operation, while its strong adhesion and mechanical compliance facilitate integration with screen-printed electrodes for low-cost, disposable use. These attributes establish a practical platform for fast, sensitive, and selective glucose quantification in fresh produce and point-of-use food monitoring.

Rosa roxburghii Tratt., a vitamin C-rich edible and medicinal fruit native to southwest China, plays a vital role in poverty alleviation and economic development in mountainous regions. In this study, Neofusicoccum parvum was identified for the first time as a pathogen causing fruit rot in R. roxburghii . Koch's postulates were fulfilled by re-isolating the fungus from artificially inoculated fruits, confirming its pathogenicity. Morphological and molecular analyses further validated the pathogen's identity. The optimal growth conditions for N. parvum were determined to be 28–30 °C and pH 5, with D-fructose and NH 4 Cl as the preferred carbon and nitrogen sources, respectively. Continuous light exposure was found to maximize mycelial growth. Among six tested plant extracts, osthol, Scutellariae Radix extract, and matrine exhibited notable antifungal activity, with osthol showing the highest efficacy (EC 50 = 30.57 μg/mL). Field trials demonstrated that 1% osthol emulsion in water (EW), applied at 300–500-fold dilution, achieved 60.68%–77.57% control efficacy against fruit rot after 21 d of the second application. This performance was comparable to the chemical fungicide 10% difenoconazole water dispersible granule (WG) (67.58%–81.04% efficacy at 5000–7000-fold dilution). This study provides a scientific basis for the biocontrol of N. parvum -induced fruit rot disease in R. roxburghii .

Far-red light plays a crucial role in plant growth, development, and flowering as a light signal. However, efficiently obtaining far-red light that well-matches the plant-photosensitive pigment Pfr remains a significant challenge in indoor agriculture. In this study, a far-red phosphor, BaGd2Al2Ga2GeO12:Cr3+(BGAGG:Cr3+), was successfully synthesized, using a high-temperature solid-phase method. Under 450 nm excitation, its emission maximum is at 712 nm with a full width at half maximum (FWHM) of 92 nm, which well-matches with Pfr. Combined with a blue LED chip, this phosphor was used to create a pc-LED device for bok choy and Micro-Tom cultivation experiments. Under the irradiation of far-red light, the biomass of bok choy increased by 39%, and the flowering and fruiting of Micro-Tom was promoted, demonstrating its potential in plant lighting applications.
