Yunnan ‘Xiangshui’ lemon ( Citrus × limon ‘Rosso’ ) is a unique regional citrus variety with rich aroma and nutrients. However, the functional potential of its albedo remains underexplored. To optimize whole-fruit utilization and evaluate the effects of albedo incorporation in juice production, this study systematically compared the flavor and nutritional profiles of juices prepared with varying proportions of albedo. Juices with higher albedo content exhibited elevated sesquiterpene levels, contributing to improved aroma. They also showed increased concentrations of polyphenols, such as naringin (246.48 ± 7.40 μg L −1 ), minerals, particularly potassium (2187.50 ± 46.50 mg kg −1 ), and vitamin C (56.80 ± 0.68 mg 100 g −1 ), suggesting potential as dietary supplements. Aspartic acid (69.16% relative abundance, w /w) enhanced umami and sourness in albedo-rich juice. These findings demonstrate that albedo addition enhances both flavor and nutritional quality of ‘Xiangshui’ lemon juice, offering a promising strategy for sustainable juice processing and comprehensive fruit utilization.

Postharvest losses, specifically due to Penicillium italicum disease, pose a significant challenge to the mandarin industry. To enhance mandarin preservation efficacy, this study developed a chitosan (CS)-based berberine sulfate/alpha-lipoic acid composite film (CS@BS/ALA) and evaluated its effects on mandarin preservation. Among the various concentrations, 4 % CS demonstrated optimal wettability and adhesion. Incorporating BS/ALA into CS formed a dense double-network structure that reduced oxygen permeability. CS@BS/ALA treatment effectively inhibited weight loss, delayed fruit softening, maintained gloss, and preserved the brix acid ratio. It also enhanced antioxidant capacity by reducing malondialdehyde (MDA) content and sustaining superoxide dismutase (SOD) and phenylalanine ammonia-lyase (PAL) activities. Furthermore, antimicrobial tests revealed pronounced inhibitory effects of CS@BS/ALA against Penicillium italicum . These findings indicate that CS@BS/ALA extends mandarin shelf life by regulating respiratory metabolism, enhancing antioxidant defenses, and suppressing microbial infection, thereby providing an innovative solution for reducing postharvest losses.

Active antibacterial packaging plays a significant role in addressing the food safety issues caused by pathogen contamination. In this study, quercetin (QCT) encapsulated in liposomes (QCT@LIPs) was embedded into the konjac glucomannan/ polycaprolactone (KGM/PCL) matrix to fabricate a photodynamic antibacterial electrospun nanofiber film (QCT@LIPs/KGM/PCL) for application in fruit preservation. Compared to QCT, QCT@LIPs exhibited a more favorable spherical morphology, smaller particle size, and a more negative zeta potential, which collectively enhanced their stability. Additionally, QCT@LIPs/KGM/PCL demonstrated excellent mechanical, hydrophobicity, barrier, biodegradability properties, and controlled sustained release capabilities. Under blue light irradiation, QCT@LIPs/KGM/PCL generated reactive oxygen species (ROS), achieving >90% inhibition rates against Staphylococcus aureus ( S.aureus ) and Escherichia coli ( E.coli ). The films effectively suppressed microbial growth during fruit storage, minimizing the loss of weight, hardness, and soluble solid content (TSS). These results highlight QCT@LIPs/KGM/PCL as a multifunctional, eco-friendly packaging systems that integrates photodynamic antimicrobial activity with sustained release, offering significant promise for advanced food preservation.

To address the demand for sustainable postharvest preservation, this study developed a chitosan-based composite film integrated with γ -cyclodextrin ( γ -CD) microcapsules encapsulating proanthocyanidins and cinnamaldehyde. The primary objectives were to evaluate the film’s physicochemical properties and assess its efficacy in mitigating quality deterioration in citrus fruits during storage. Results demonstrated that the composite film significantly reduced weight loss (5.78%), maintained firmness (≥ 80% retention), and delayed changes in total soluble solids (TSSs) and pH compared to uncoated controls. Furthermore, it inhibited vitamin C degradation (≤ 35% loss) and extended shelf life to 40 days at 15°C by suppressing microbial growth and oxidative stress. The synergistic effects of chitosan’s film-forming capacity and the sustained release of bioactive compounds from γ -CD microcapsules, among which proanthocyanidins had good antioxidant function and cinnamaldehyde had good antibacterial property, played a key role in the preservation of citrus fruits.

Simple SummaryBactrocera dorsalisis a highly invasive polyphagous pest of fruit and vegetable, causing severe economic loss and trade restrictions by ovipositing inside hosts. Cryptic feeding habits of larval stages, strong flight ability of adults and prevalence of insecticide resistance reduce the efficiency of chemical control. Currently, the most cost-effective tool is olfaction-based trapping. Methyl eugenol (ME), a naturally occurring compound in some plants, alone or combination with insecticides has been widely used as a male attractant to monitor and controlB. dorsalispopulations for seven decades. Intense ME selection under laboratory conditions has resulted in the evolution of non- responsiveness inB. dorsalisand field management strategies based on ME has failed to eradicate recolonization ofB. dorsalisin some islands. However, the levels of ME responsiveness inB. dorsalisfield populations in China is unknown. In this study, we found that field populations had lower ME sensitivity compared to the susceptible strain. Furthermore, the results of olfactory organs, gene expressions and the bioassays showed that odorant binding protein (BdorOBP2, BdorOBP83b) and P450 may be involved in the lower sensitivity. The findings will guide the use of lures combined with insecticides and help to exploit molecular targets for the development of new attractants.AbstractBactrocera dorsalisis a notorious polyphagous pest in China, and its management strategies largely depend on methyl eugenol (ME), which has been widely used as an attractant to monitor and eradicateB. dorsalispopulations for seven decades. However, the non-responsiveness levels in fieldB. dorsalispopulations to ME is unknown. In this study, we monitored the response to ME in field populations from the four most heavily infested provinces in China, and the results showed that the populations had lower sensitivity to ME relative to GZS susceptible strain. The percent responsiveness of the lowest sensitivity population was 5.88-, 3.47-, and 1.47-fold lower relative to the susceptible strain at doses of 1, 10, and 100 µL of ME, respectively. Gene expression analysis and inhibitor assays further revealed that odorant binding protein (BdorOBP2, BdorOBP83b) and the P450 enzyme system may be associated with the lower response to ME. To our knowledge, this work is the first to report that the P450 enzyme system confers a lower responsiveness to lure insects. These findings provided valuable insights for exploiting ME non-responsiveness to protect sterile males from ME-based control strategies and the use of lures combined with insecticides.Keywords:methyl eugenol;non-responsiveness;odorant binding protein;P450;trapping

This study aimed to optimize the extraction of feijoa pulp pectin and discuss the impact of different extraction methods on the physicochemical and functional properties of pectin. Under the optimum conditions, the pectin yields of microwave-enzyme-assisted extraction (PMEAE, 13.31%) and enzyme-assisted extraction (PEAE, 9.26%) were significantly higher than that of conventional heating extraction (PCHE, 7.64%). Compared to PCHE, PMEAE and PEAE exhibited higher degree of esterification of 68.43% and 67.89%, respectively, coupled with more highly branched side chains, which was confirmed by Fourier-transform infrared (FTIR) analysis. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) analysis showed that PMEAE and PEAE exhibited superior thermal stability. PEAE and PMEAE owned higher viscosity and superior antioxidant biological activity than PCHE. This study suggested that feijoa pectin by microwave enzyme-assisted or enzyme-assisted extraction contained more branched side chains and had better physicochemical and functional properties.

Platanus fruit-like nickel cobalt ammonium phosphate/MWCNTs composites for high-performance supercapacitors were successfully prepared by a two-step hydrothermal method using NiSO 4 ⋅ 6H 2 O, CoSO 4 ⋅ 7H 2 O, (NH 4 )H 2 PO 4 and MWCNTs as raw materials, respectively. The effects of MWCNTs addition on the structure and properties of the composites were investigated. The results showed that when the doped amount of MWCNTs is 7.3 wt.%, the as-prepared NCAP/M7.3 composite presented an obvious platanus fruit likeness, its surface is rough and porous with a diameter of 3–5 μ m. Compared with the other MWCNTs contents, the NCAP/M7.3 electrode obtained under this condition showed the best capacitive performance. The discharge specific capacity was up to 1270 F g − 1 at current density of 1 A g − 1 , which remains to be 902 F g − 1 even at a high density of 10 A g − 1 . The results show that the target sample can be the ideal electrode material for supercapacitor.

A defective UiO-66 with rich defect sites was synthesized by a modulator-induced defect formation approach and used as the solid-phase microextraction (SPME) fiber coating material. The extraction experimental results showed that the defective UiO-66 coating can selectively extract the fungicides chlorothalonil, vinclozolin, dimethachlon, procymidone and iprodione with a high adsorption capability. The superior adsorption capability can be attributed to hydrophobic, Lewis acid-base and hydrogen bonding interactions. After optimization, a SPME with the defective UiO-66 as the fiber coating combined with GC–MS detection was established for the sensitive and selective determination of the five fungicides in fruit samples. Under the optimized experimental conditions, the quantitative linear response was in the range of 0.83–300 ng g −1 , with the coefficients of determination in the range from 0.9970 to 0.9986 and the limits of detection between 0.25 and 9.0 ng g −1 for the analytes. The method was successfully applied for the determination of the fungicides in different fruit samples. Satisfactory method recoveries (82.7%-117.7%) and good precisions with the relative standard deviations being from 3.2% to 12% were achieved.

Gardenia fruit extract like gardenia blue is untable under light exposure and its application need expansion. Gardenia blue was proposed to be stabilized in triple-induced microgels from cooperative effects of gelatin, β-cyclodextrin and chitooligosaccharide, and its emulsifying ability and 3D printing potential were subesequently explored. The synergetic effects on gardenia blue due to the intermolecular interactions including hydrogen bonding and electrostatic interaction, contributed to the high UV irradiation stability of complexes. The complex microgels could absorb onto oil-water interface with emulsifying property, and the obtained high internal phase emulsions (HIPEs) illustrated outstanding centrifugal stability and great storage stability with low and uniform optical microscopic droplet diameters. The obtained HIPEs possessed excellent shearing thinning properties, excellent structure reversibility, high-degree reticulation, outstanding thixotropy , great elasticity, high cohesive energy and mechanical strength. 3D printing of HIPEs onto food also demonstrated high shape fidelity with low deviation. The findings illustrate the way of stabilizing gardenia blue in microgels by triple synergies, demonstrate the potential as stabilizer for developing HIPEs, and offered reference for highly-added-value utilization in the personalized 3D food products.

Litchi fruit is susceptible to pericarp browning, which is largely due to the oxidation of phenols in pericarp. However, the response of cuticular waxes to water loss of litchi after harvest is less mentioned. In this study, litchi fruits were stored under ambient, dry, water-sufficient, and packing conditions, while rapid pericarp browning and water loss from the pericarp were observed under the water-deficient conditions. The coverage of cuticular waxes on the fruit surface increased following the development of pericarp browning, during which quantities of very-long-chain (VLC) fatty acids, primary alcohols, and n -alkanes changed significantly. Genes involved in the metabolism of such compounds were upregulated, including LcLACS2 , LcKCS1 , LcKCR1 , LcHACD, and LcECR for elongation of fatty acids, LcCER1 and LcWAX2 for n- alkanes, and LcCER4 for primary alcohols. These findings reveal that cuticular wax metabolism may take part in the response of litchi to water-deficient and pericarp browning during storage.

Red-flowered oil-tea camellia (ROC) is an important woody oil species growing in the south, and its oil has high nutritional value. There are four main species ofROCin China, namely,Camellia chekiangoleosa(CCH),Camellia polyodonta(CPO),Camellia semiserrata(CSE) andCamellia reticulata(CRE). Reports on the comprehensive comparative analysis ofROCare limited. This study investigated the fruit characteristics and nutritional components of fourROCfruits, and the results showed thatROChad high oil content with levels of 39.13%–58.84%, especially theCCHfruit, which reached 53.6–58.84%. The contents of lipid concomitants ofROCoil were also substantial, including β-amyrin (0.87 mg/g–1.41 mg/g), squalene (0.43 mg/g–0.69 mg/g), β-sitosterin (0.47 mg/g–0.63 mg/g) and α-tocopherol (177.52 μg/g–352.27 μg/g). Moreover, the transverse diameter(TD)/longitudinal diameter (LD) of fruits showed a significant positive correlation with the oil content, andROCfruits with thinner peels seemed to have better oil quality, which is similar to the result of the oil quality evaluation obtained by the gray correlation coefficient evaluation method. FourROCoils were evaluated using the gray correlation coefficient method based on 11 indicators related to the nutritional value ofROC.CCHoil had the highest score of 0.8365, and YS-2 (a clone ofCCH) was further evaluated as the bestCCHoil. Finally, the results of heatmap analysis showed that triglycerides could be used as a characteristic substance to distinguishCCHoil from the other threeROCoils. The PLSDA (Partial least squares regression analysis) model and VIP (Variable important in projection) values further showed that P/S/O, P/O/O, P/L/L, P/L/Ln, S/S/O, S/O/O and P/S/S (these all represent abbreviations for fatty acids) could be used as characteristic differential triglycerides among the fourROCoils. This study provides a convenient way for planters to assess the nutritional quality of seed oil depending on fruit morphology and a potential way to distinguish between variousROCoils.Keywords:red-flowered oil-tea camellia;Camellia chekiangoleosaoil;correlation analysis;gray correlation coefficient;triglycerides
