pH-responsive intelligent films for food freshness monitoring have attracted a great deal of attention in recent years. In this study, dragon fruit peel was used to develop a new type of active and functional film. The film was prepared by using residues extracted from dragon fruit peel (RPP) as the matrix, Curcumin (Cur) as the active ingredient and ZnO-NPs as the antibacterial material. The effect of the incorporation of Cur and ZnO-NPs on the properties of the films was studied. The addition of Cur increased the oxidation resistance of the films (more than 90 %), and ZnO-NPs increased the bacteriostasis and hydrophobicity of the films (water contact angle (WCA):122.00°). The colorimetry response of the RPP/Cur/ZnO-NPs film was performed, and the color of the film changed from brown to tawny to yellow. These properties highlight the potential of the RPP/Cur/ZnO-NPs film for practical applications, indicating its potential applications as smart packaging materials for the food industry. Therefore, the RPP/Cur/ZnO-NPs composite film based on dragon fruit peel can be used to monitor the freshness of milk, and to a certain extent contribute to the sustainable value of dragon fruit by-products in the food industry.

Natural food preservatives composed of environmentally-friendly, non-toxic, and biodegradable components have gradually become excellent alternatives to traditional food preservatives. This study developed a fully biomass-based, non-toxic, and eco-friendly food preservation material by encapsulating oregano essential oil (OEO) in self-assembled casein (CA)/chitosan (CS) microcapsules crosslinked with tannic acid (TA) via multiple sites. OEO was successfully encapsulated with an efficiency of 92.5 %. Structural analysis revealed that TA crosslinking significantly altered the secondary structure of casein (increasing α-helix content) and enhanced thermal stability. In food-simulating media, the microcapsules exhibited sustained OEO release across four typical environments, confirming their potential for extensive food preservation applications. The microencapsulated emulsion exhibited prolonged antioxidant and antibacterial activities compared with free OEO. Fruit preservation tests verified that the emulsion effectively extended the shelf life of perishable fruits under ambient conditions. Notably, the use of food-grade materials and a TA-mediated multipoint cross-linking strategy not only enhanced microcapsule stability but also offers an innovative approach for developing safe and sustainable food preservatives.

Pericarp browning is a vital factor limiting postharvest life of litchi fruit. The influence of vitexin on pericarp browning as well as the related mechanisms in litchi fruit were investigated. Results demonstrated that 1 mM vitexin ameliorated pericarp browning when litchi fruit were stored at 25 °C. Meanwhile, vitexin blocked reactive oxygen species (ROS) production but increased the glutathione peroxidase activity, thereby playing a protective role in oxidative injury. Additionally, vitexin attenuated ATP content decline in relation to regulation of LcSnRK1 as well as LcbZIP1/3 expressions. Furthermore, vitexin regulated expression levels of autophagy-related genes. Finally, LcbZIP3 activated the expressions of LcATG2 and Lcbeclin-1-like protein based on dual-luciferase report (DLR) assay. This is the first report that confers vitexin-meditated protective role in delaying litchi pericarp browning that could be linked to its effects on autophagy particularly regulated via LcSnRK1a–LcbZIP1/3 signaling pathway. Vitexin treatment might be an effective approach to control postharvest senescence of fruit during storage.

Feizixiao litchi ( Litchi chinensis Sonn.), the most widely cultivated commercial variety in China, holds significant economic and social value. However, uneven coloration on the fruit surface markedly diminishes its market appeal. This study investigated the effect of foliar application of ZnO (100 mg/L) and TiO 2 (50 mg/L) nanoparticles (NPs) on the color and quality of Feizixiao during fruit expansion, with water sprayed fruits serving as the control. At harvest, fruits treated with ZnO NPs (63.4 ± 9.5%) and TiO 2 NPs (70.4 ± 8.8%) exhibited significantly enhanced skin coloration rates compared to the control (53.3 ± 9.2%). RNA sequencing of pericarp tissues revealed that the genes associated with anthocyanin biosynthetic enzymes (DFR and UFGT) and transcription factors ( MYB, bHLH, WD40 , and NAC ) were upregulated by both ZnO and TiO 2 NPs sprays , leading to enhanced anthocyanidin synthesis and concomitant fruit pigmentation. Meanwhile, ZnO NPs treatment upregulated the expression of genes encoding Mg and Zn transporters, leading to elevated pericarp Mg and Zn. However, TiO 2 NPs spray reduced S assimilation in pericarp by downregulating the expression SULTR3;4 gene, which was negatively associated with enhanced photosynthesis as well as photorespiration. The alteration of pericarp Mg, Zn, and S was conducive to anthocyanidin synthesis and accumulation. Therefore, ZnO NPs treatment promoted fruit pigmentation by increasing pericarp Mg, Zn, Cy3R, and phenolic copigments accumulation (EC, rutin), while TiO 2 NPs spray enhanced coloration by reducing pericarp S and increasing Cy3R and copigments (PC B2, Qu3G, ferulic acid, and Ka3G). Overall, this study offers a viable strategy for improving fruit coloration in litchi.

Phyllanthus emblica L . ( P. emblica L.) is a medicine and food homologous plant, whose fruit is acknowledged by the International Health Organization for its high nutritional value. However, eco-friendly and highly efficient methods for extracting the active components from P. emblica L. fruits are currently lacking. In this study, we explored the potential of an eco-friendly enzyme-assisted extraction method for enhancing the extraction of phenolic compounds from P. emblica L., then optimized the extraction process using response surface methodology. After optimization, the contents of gallic acid and total polyphenols reached 33.98 ± 0.15 mg/g and 147.92 ± 1.21 mg GAE/g, respectively. The optimized P. emblica L. extract showed promising anti-inflammatory, antioxidant, and hypoglycemic properties. These findings suggest a viable alternative for obtaining multifunctional extracts from P. emblica L., which have important applications in the functional food and pharmaceutical sectors.

Pectin derived from the fruit of Clausena lansium (Lour.) Skeels, commonly known as Wampee, possesses diverse bioactivities and holds significant potential for applications in food products. To broaden Wampee's application range, deep eutectic solvent (DES) was optimized for pectin extraction using response surface methodology. The fundamental and functional properties of DES-extracted pectin (D-CP) were compared to water-extracted pectin (W-CP). Extracted under the optimal extraction conditions (oxalic acid:choline chloride ratio was 1:1, reagent content was 10.2% (w/v), extraction time was 154 min, temperature was 82.5°C, and liquid: solid was 10.0 mL/g), D-CP was identified as Rhamnogalacturonan-dominated pectin. D-CP's molecular weight (129 kDa) and degree of esterification (61.05%) were lower than those of W-CP. However, D-CP exhibited a superior yield (18.09%) and enhanced functional properties, including higher purity, improved emulsifying stability and activity, better foaming capacity, and stronger foam stability. Additionally, D-CP demonstrated excellent solubility alongside notable antioxidant activities. Overall, these advanced properties highlight D-CP's promising potential for applications in the food and pharmaceutical industries, with DES proving to be an effective solvent for efficient extraction of bioactive pectin from Wampee.

Chemical detergents are extensively used to remove pesticide residues and foodborne pathogens on fresh fruits, but their residues are toxic to humans. To address this issue, a dual-functional starch copolymer, specifically dialdehyde starch-grafted ε-polylysine copolymer (DIA-ε-PL starch), was synthesized utilizing native starch with surfactant properties and the natural antimicrobial cationic peptide ε-polylysine (ε-PL). The effectiveness of DIA-ε-PL starch as a fruit detergent was subsequently evaluated. Raman imaging and HPLC results indicated that the removal efficiency of chlorothalonil (CHT) reached 96.62% under the optimal conditions which involved washing apples with a 1% corn-DIA-0.16-ε-PL solution at 30°C for 15 min. Compared to traditional washing reagents, DIA-ε-PL starch not only exhibited higher CHT removal efficiency without migrating into apple tissues but also demonstrated superior antibacterial effect against S. aureus (94.64%) and E. coli (98.78%). The DIA-ε-PL starch exhibits significant potential as a fruit-specific detergent due to its non-toxicity, economy, sustainability, and eco-friendliness.

Camellia oleifera fruit shells (CFS), a by-product of Camellia oleifera oil production industry, are rich in hemicellulose and lignin components. In this work, efficient fractionation and valorization of CFS were investigated. Malic acid (MA) pretreatment (6 g/L MA, 5 g/L 2-naphthol (2 N), 160 ℃, 30 min) resulted in a maximum yield of XOSs of 73.3 %. Besides, alkaline hydrogen peroxide/ethanol (AHP/E) biphasic delignification at mild conditions extracted over 90 % lignin from the MA2N pretreated solid, which was fabricated as lignin nanoparticles (around 170 nm) for drug delivery. Finally, the MA2N-AHP/E combinational pretreatment provided a cellulose-enriched residue, with cellulose retention rate of 93.1 %, which was enzymatically converted to glucose with nearly 100 % hydrolysis efficiency. Results revealed that the combinational pretreatment was an ideal first step of lignocellulosic biorefinery using CFS as feedstock for co-production of XOSs, fermentable sugars and lignin nanocarriers, which potentially alleviated environmental problems caused by discarding, burning and composting of CFS.

Ethylene causes faster deterioration of perishable crops during postharvest transportation and storage. The present study aimed to develop TiO2-coated nanofibers with efficient photocatalytic activities to enhance the degradation of fruit-emitted ethylene. The consecutive electrospinning of polyacrylonitrile (PAN) and TiO2deposition was successfully performed to produce PAN@TiO2nanofibers. The scanning electron microscopy results indicate the uniform distribution of TiO2nanoparticles on the surface of the PAN nanofiber. The PAN@TiO2composite nanofibers exhibited enhanced photocatalytic activity for ethylene degradation under low-intensity UV light irradiation. Furthermore, a tomato fruit-ripening test confirmed the effectiveness of the PAN@TiO2nanofibers. The PAN@TiO2nanofibers exhibited effective ethylene degradation and slowed the color shift and softening of the tomatoes during storage. The results suggest great potential for use of the PAN@TiO2composite nanofibers as ethylene scavenging packaging material for fresh fruits and vegetables.

Paraquat (PQ) is a kind of herbicide, which is highly toxic to human body. In this work, we proposed a fast and simple detection method for PQ in aqueous samples based on electrostatic interactions between modified gold nanoparticles (Au NPs) and PQ. Au NPs were first modified with sodium 3-mercapto-1-propanesulfonate (Au NPs-3MPS). 3MPS with negative charge can interact with nitrogen atoms of PQ with positive charge via electrostatic force. As a result, Au NPs-3MPS aggregated together. Accordingly, the color of Au NPs-3MPS colloid changed from red to blue-gray, and the UV–vis absorption spectrum changed accordingly. The detection limit of PQ is 0.1 mg/L by naked eyes, and 0.001 mg/L by UV–vis spectroscopy. Moreover, this detection method has good specific selectivity and anti-interference performance, and it has been successfully used for detecting PQ in real environmental samples and fruit juice samples.

The development of water treatment materials using environmentally friendly natural biomasses as substitutes plays an increasingly important role in environmental protection. Zeolitic imidazolate framework-8 (ZIF-8) is often used for the catalytic degradation of dye wastewater, but due to its small particle size, its disadvantage of easy agglomeration prevents it from being fully functional. Herein, we report an efficient method for synthesizing biomasses/ZIF-8 using four different fruit peels as carriers. ZIF-8 nanoparticles are in-situ grown uniformly on their surface. The Brunauer–Emmett–Teller surface area of shaddock peel/ZIF-8 was found to be 752.15 m2g–1. After catalytic activity comparison, the loose shaddock peel/ZIF-8 showed the fastest and most significant degradation efficiency of 94% in methylene blue aqueous solution and could be used multiple times through a simple washing process.

This study aims to produce an inclusion complex between β-cyclodextrin (β-CD) and sea buckthorn fruit oil (SBFO) by using the saturated aqueous solution method and then to compare the resultant solution with the crude mixtures. In this study, the SBFO is extracted by Soxhlet extraction, which is optimized through the single-factor test. The main constituent of the SBFO is identified by gas chromatography-mass spectrometry (GC-MS), which confirms eight fatty acids. Fourier transform infrared spectroscopy, thermogravimetric analysis-differential scanning calorimetry, optical microscopy, scanning electron microscopy, and the result-characterized synthesized compounds confirm the formation of stable inclusion compounds by the SBFO with β-CD. The yield values of the inclusion complex and the SBFO loading content are 64.87 ± 2.26% and 9.2 ± 1.58%, respectively. Comparing the crude fruit oil, β-CD–SBFO, and saponified fruit oil reveals differences in their 2,2-diphenyl-1-pycrylhydrazyl and 2,2′-azinobis-(3-ethylbenzthiazoline-6-sulfonate) antioxidant activities. These findings suggest that the SBFO inclusion complex after β-cyclodextrin is stabilized and is a good antioxidant. This solution improves the inadequacy of the water solution and the instability of the SBFO. This study also implies that β-CD is a cost-effective and straightforward carrier for extending the applications of SBFO as a food or medicinal additive. Practical applications : In this experiment, the SBFO is converted from oil to powder to increase its efficacy as an additive to health and food products.
