A convenient, efficient, and green dispersive liquid-liquid microextraction based on the in situ formation of solidified supramolecular solvents combined with high performance liquid chromatography was developed for the determination of four phenylurea herbicides in liquid samples, including monuron, monolinuron, isoproturon, and chlortoluron. Herein, a novel supramolecular solvent was prepared by the in situ reaction of [P 4448 ]Br and NH 4 PF 6 , which had the advantages of low melting point, high density, and good dispersibility. In addition, the microscopic morphology and physical properties of supramolecular solvent were characterized, and the extraction conditions were optimized. The results showed that the analytes had good linearity ( R 2 > 0.9998) within the linear range. The limits of detection and quantification for the four phenylurea herbicides were in the range of 0.13–0.19 μg L −1 and 0.45–0.65 μg L −1 , respectively. The prepared supramolecular solvent is suitable for the efficient extraction of phenylurea herbicides in water, fruit juice, and milk.

Purple passion fruit peel (PPFP) is a common biomass waste. Meanwhile, hydrothermal carbonization (HTC) is a common technology used for thermal conversion of biomass waste. Herein, the aqueous phase (AP) of PPFP was determined using HTC, and its properties were studied. Results indicated that AP exhibited strong antibacterial properties ( E. coli : 22.50 ± 0.80 mm, S. aureus : 23.28 ± 0.56 mm) and antioxidant capacity (EC 50 : 4.46 mg/mL). Chitosan (CS) and bacterial cellulose nanofibers (BCNFs) were used as the film matrix, and AP was introduced as an antimicrobial substance to develop AP/CSBC films. The interaction between the aqueous phase substances (APSs) and the CSBC film matrix was verified using Fourier transform infrared spectroscopy and X-ray diffraction analysis. The AP/CSBC films demonstrated excellent antibacterial and antioxidant activities. Blueberry preservation test showed that the AP/CSBC films can effectively extend the shelf-life of the fruit, indicating their potential as novel food packaging materials. This study present a method of high-value PPFP utilization and offers an effective approach to preparing biodegradable antibacterial food preservation films.

An effective and sensitive SERS substrate (TPDH-COF/Au NPs) on a covalent organic framework (TPDH-COF) decorated with gold nanoparticles (Au NPs) was fabricated via electrostatic self-assembly and successfully applied for the determination of thiabendazole (TBZ) in fruit juice. The “raspberry-like” structure SERS substrate combined the properties of the abundant “hot spots” between the Au NPs and the adsorption performance of TPDH-COFs for trace analytes. Excellent SERS performance was observed, which achieved a high enhancement factor value of 2.01 × 108 for rhodamine 6 G, with considerable reproducibility and excellent long-term stability of at least 28 d. The limit of detection was estimated to be 5 ppb for TBZ in fruit juice. The result demonstrated that the TPDH-COF/Au NPs have great potential for SERS analyses and determination of pesticide residues in foods.

Bio-based food packaging materials have elicited growing interests due to their great degradability, high safety and active biofunctions. In this work, by simultaneously introducing the polyphenolic extracts from Capsicum annuum leaves and ferric ion (Fe 3+ ) into the Polyvinyl alcohol/kappa-carrageenan (PVA/κ-carrageenan)-based film-forming matrix, an active package film was developed, with the purpose to improve the food shelf life. The experimental results indicated that the existence of Fe 3+ can not only improve the mechanical properties owing to the multiple dynamic coordinated interactions, but also endow the composite films with excellent fire-retardancy. Moreover, the composite films could display excellent UV resistant performance, water vapor/oxygen gas barrier properties and antioxidant activities with the corporation of polyphenols. In particular, the highest DPPH and ABTS radical scavenging capacities for composite film (PC-PLP7 sample) were evaluated to be 82.5 % and 91.1 %, respectively. Higher polyphenol concentration is favorable to the bio-functions of the materials. Benefitting from these features, this novel kind of films with a dense and steady micro-structure could be further applicated in fruit preservations, where the ripening bananas were ensured with the high storage quality. This integration as a prospective food packaging material provides an economic and eco-friendly approach to excavate the high added-values of biomass.

Fingered citron ( Citrus medica L. var. sarcodactylis Swingle) is a medicinal and edible citrus fruit cultivated in several major production regions of China. However, comprehensive information on its regional metabolite variation and its chemical differentiation from chayote ( Sechium edule ), a botanically unrelated commodity that may be confused with fingered citron because of partially overlapping Chinese vernacular names, remains limited. In this study, untargeted UPLC‐Q‐Orbitrap MS/MS was used to profile fingered citron samples from Zhejiang (CF1), Sichuan (CF2), Guangdong/Guangxi (CF3), and Yunnan (CF4), together with chayote samples used as a targeted authentication comparator (CFM). A total of 380 metabolites were putatively annotated, including 47 secondary metabolites comprising 23 flavonoids, 8 terpenoids, 8 phenols, 3 coumarins, 3 alkaloids, and 2 steroids. Multivariate analyses and hierarchical clustering identified 65 differential metabolites, including 19 secondary metabolites, that clearly separated the five sample groups within the present dataset. The very high cross‐validated Q 2 values should nevertheless be interpreted cautiously because of the large taxonomic and metabolic distance between C. medica and S. edule and the limited sample size. The interspecific separation was therefore interpreted as an expected chemotaxonomic difference with practical authentication value, rather than as a comparison between biologically equivalent taxa. Phenylalanine metabolism and flavone and flavonol biosynthesis showed the strongest nominal enrichment, although neither remained significant after FDR correction. These results provide a metabolite reference for regional quality discrimination of fingered citron and identify candidate chemical features for its targeted authentication against chayote. Further validation using independent samples, additional production years, and other potential comparator commodities is required before routine application. Untargeted UPLC‐Q‐Orbitrap MS/MS metabolomics was used to profile fingered citron ( Citrus medica ) from four Chinese production regions (CF1–CF4) and chayote ( Sechium edule , CFM). Of 380 putatively annotated metabolites, 65 differential metabolites distinguished the five groups, clearly separating chayote from fingered citron and highlighting regional chemical variation among fingered citron cultivars.

Terpenoids and esters were the dominant volatiles in the mature longan fruits. • Characteristic aroma compounds were identified and validated with authentic standards. • Key compounds responsible for fresh-green, floral, and winy aromas were screened. Longan fruit is renowned for its sweet aromatic flavor and nutrition; however, the essence of its aroma formation remains unclear. This study employed three cultivars with distinct aroma profiles—‘Shixia’ (SX), ‘Lidongben’ (LDB), and ‘Xiangcui’ (XC)—for sensory evaluation and volatile profiling throughout fruit development. Terpenoids and esters rapidly accumulated and dominated during fruit expansion. Integrating multivariate analysis, odor activity value (OAV) and GC–olfactometry (GC–O), this study first identified 19 characteristic aroma compounds and elucidated their biosynthetic pathways. Seven key compounds defining aroma types were distinguished: ( E )-β-ocimene as a common background aroma contributed to fresh green scent of SX, linalool and methyl salicylate provided floral notes in LDB, while four ethyl esters imparted a winy aroma to XC. Molecular docking revealed spontaneous binding (−2.57 to −5.35 kcal/mol) of all key compounds to olfactory receptors. These findings clarify the chemical basis underlying aroma diversity in longan and support flavor quality improvement.

Oligosaccharides (OSs) are abundant in natural products (NPs), yet their rapid and effective characterization, especially for absorbed OSs, remains challenging. In this study, an enhanced data acquisition and analysis strategy using three derivative labels was proposed and successfully applied to characterize the in vitro and in vivo profiles of OSs in Mori Fructus fruit (MF). For data acquisition, Data Independent Acquisition (DIA) was performed to maximize the MS information of OSs, followed by Mass Defect Filtering (MDF) using Metabolynx XS™ to automatically exclude irrelevant ions and generate Precursor Ion List (PIL) of potential OSs. A PIL-based Data Dependent Acquisition (DDA) was subsequently implemented to obtain clear MS 2 spectra. For data analysis, fragmentation behaviors of OS reference standards were evaluated to obtain Characteristic Fragment Ions (CFIs) and Neutral Losses (NLs) that served as criteria for eliminating false-positives. Ultimately, 79 OSs (44 neutral-reducing OSs, 11 nitrogen-reducing OSs, 20 acid-reducing OSs, and 4 neutral non-reducing OSs) were characterized in MF extract. In addition, 68 OS prototypes were detected in intestinal contents and 15 OS prototypes were observed in plasma. In conclusion, this novel strategy enabled stepwise screening, classification and systematic characterization of OSs in NPs in vitro and in vivo .

This study reports the carbendazim (CBZ) detecting capability of spinel cobaltite MnCo 2 O 4 (MCO) synthesized via a microwave-assisted hydrothermal approach. The MCO-modified screen-printed electrode (MCO/SPE) exhibited excellent electrocatalytic activity toward CBZ oxidation. As a result, the proposed sensor enables sensitive CBZ detection over two distinct linear ranges (0.05–5 μM and 25–500 μM), with a low detection limit of 0.02 μM and a high sensitivity of 6.46 μA μM −1 cm −2 . The enhanced sensing performance is attributed to the synergistic redox activity of Co 2+ /Co 3+ and Mn 2+ /Mn 3+ couples, which enhance both electrical conductivity and catalytic activity, together with the nanorod morphology that promotes efficient diffusion of CBZ molecules and electrolyte species. The applicability of the MCO/SPE was further validated through effective CBZ detection in fruit and vegetable samples as compared with the liquid chromatography–tandem mass spectrometry (LC-MS/MS) method, showing strong potential for food safety monitoring.

Litsea cubeba (Lour.) Pers. is an important industrial tree in southern China and Southeast Asia. We surveyed and sampled wild L. cubeba in 32 provenances spread across nine provinces of China. We used nested variance analysis, multiple comparisons analysis, hierarchical clustering analysis, Pearson’s correlation analysis, path analysis with multiple stepwise regression, detrended correspondence analysis, redundancy analysis, and variance partitioning analysis to evaluate the phenotypic diversity of fresh fruit yield (FFY) and essential oil (EO) characteristics of L. cubeba , and to explore the relationship between the main habitat factors and phenotypic diversity. We detected wide phenotypic diversity in FFY, EO content (EOC), citral yield (CitrY), and the proportions of the seven main components of EOs (citral, D -limonene, 3,7-dimethyl-3,6-octadienal, 4-methyl-3-pentenal, linalool , citronellal , and 1-(cyclopanecarbonyl)piperidin-4-one). The variation was mainly derived from among provenances ( P ≤ 0.01) rather than within provenances, and the variation in FFY and CitrY was greater than that of EOC and the seven dominant components among provenances. We also detected several region-specific components of EOs in fresh fruit, including α-terpineol, geraniol , eucalyptol , and 7-methyl-3-methyleneoct-6-enal. Most of the provenances with higher FFY were distributed in southwestern China (lower longitude and latitude, and higher elevation), while most of those with higher EOC were distributed in southeastern China (higher longitude and latitude, and lower elevation). The three provenances with excellent FFY were YN-XC, GZ-ZY, and SC-KJ; the two with higher EOC were SC-KJ and HN-DX; and CitrP was higher in GZ-ZF than in other provenances. Longitude, total potassium content (TotalKC), and bulk density (BD) were the most important factors that influenced FFY diversity, while latitude, elevation, annual average relative humidity (AARH), and organic carbon content (OCC) most strongly influenced EOC diversity, and annual average temperature and annual average maximum temperature (AAMaxT) influenced CitrP diversity. The six main habitat factors together explaining the largest proportions of phenotypic diversity were longitude, AARH, AAMaxT, elevation, latitude, and soil total phosphorus content (TotalPC). Higher soil TotalKC, BD, and TotalPC were suitable conditions for cultivation of L. cubeba to achieve higher FFY, while lower AARH and OCC were favorable for accumulation of EOs, and only lower temperature was more likely conducive to citral synthesis. The wide diversity of FFY and EO characteristics should be taken into account when selecting germplasms for protection and utilization, and the identification of the most important environmental factors affecting phenotypic diversity provides a theoretical basis for the optimization of L. cubeba cultivation.

Bamboo is a widely distributed graminaceous plant in China and is a potential source of bioactive substances. Incidentally, bamboo’s fruit is rich in phytochemicals such as polyphenols and flavonoids, which are significant to human health. In this study, we identified the phenolic compounds of the fruit and investigated the antioxidant activities ofCephalostachyum fuchsianumGamble (CFG) fruit polyphenols with in vitro and in vivo tests for the first time. UPLC–Q–TOF–MS/MS analysis results showed that the fruit contained 43 phenolic compounds, including 7 hydroxybenzoic acids, 12 flavonoids, 7 coumarins, 10 hydroxycinnamic acids, 1 terpenoid, and 5 lignans. The TPC of SP extracts was higher than that of IBPs extracts in FP and FF. The SP extracts in FP showed better antioxidant activities in vitro compared to those in FF. In addition, polyphenols from CFG fruits protected against H2O2-induced oxidative damage in HepG2 cells, and the protective effect of polyphenols in FP was superior to that in FF. The analysis results showed that CFG fruit has great potential in exploiting natural chemical substances, which can provide valuable pieces of information for the further development and utilization of CFG.Keywords:Cephalostachyum fuchsianumGamble;polyphenol;UPLC–Q–TOF–MS/MS;HepG2 cells;antioxidant activity

This study evaluated the changes of enzymes and quality properties of passion fruit juice juicing with (PFJ-1) and without seeds (PFJ-2) treated by high-pressure processing (HPP, 600 MPa/5 min) and thermal pasteurization (TP, 85 °C /30 s) during storage at 4 °C for 35 days. Juicing with seeds resulted in PFJ-1 with 76.83, 68.25 and 28.12% higher activities of polyphenol oxidase , peroxidase and superoxide dismutase than PFJ-2, respectively, and its apparent viscosity at 10 −1 s and L * were also 148.60 and 1.47% higher, respectively. The total sugars, organic acids, and volatile compounds in PFJ-1 were 9.16, 4.97 and 53.85% higher than PFJ-2, respectively. Quality properties, including sugars, organic acids, volatile compounds in PFJ-1-HPP were all more susceptible towards degradation than PFJ-2-HPP under storage, which were decreased by 21.93, 26.14 and 18.47% after storage. This research provided new insights for production of high-quality passion fruit juice. Industrial relevance At present, the passion fruit juice is the dominated product in passion fruit industry, but there are few studies reported on the difference between the juice quality under different juicing methods by juicing with or without seeds. The seeds in passion fruit contains a great variety of substances such as oxidative browning enzymes, unsaturated fatty acids , which can significantly affect the quality of passion fruit juice after entering in juice. This research is of great significance as a theoretical basis to further research on the influence mechanism of enzyme and phytochemicals in seeds on the quality of passion fruit juice, and also provides a guide to production for quality orientated passion fruit juice based on consumer and producer demands.

Citric acid-derived carbon dots (CA-CDs) without any modifications were found to have the ascorbate oxidase (AAO)-like activity. The CA-CDs have high affinity for ascorbic acid (AA), which is similar to natural AAO. The robustness of CA-CDs is greater than that of AAO. Based on the AAO mimetic activity of CA-CDs, a sensitive turn-on mode and natural enzyme-free fluorescence detection method has been developed for AA in some fruit juice and beverage samples with satisfied recoveries. This study provides CDs-based AAO mimetic nanozymes to replace the expensive natural enzymes or heavy metal-based nanozymes, which will show great potential in biological and food assays.
