Although probiotics have many health benefits, they are easily affected by the environment factors during storage and digestion in the gastrointestinal tract, resulting in a decrease or even loss of their vitality. Prebiotics have the ability to improve the survival rate and stability of probiotics, and realize their controlled release in the intestinal tract through encapsulation technology. In this review, we summarize the recent research progress of prebiotic-based delivery systems for probiotics. Both the oligosaccharides and polysaccharides that can function as both prebiotics and encapsulants are discussed. Particularly, the formation, structure, stabilizing effect, and modulation mechanism on intestinal microbiota homeostasis are described. The combination of various prebiotics for synergistic effects is also proposed. Finally, the opportunities, challenges, and future directions are highlighted.

This research investigates the development of an innovative membrane for the treatment of saline wastewater, with a specific focus on sodium ion removal. The deposition of Soy Protein Isolate (SPI) amyloid nanofibrils (ANFs) onto electrospun cellulose acetate membranes (CAMs) significantly enhanced sodium ion removal efficiency. ANFs were synthesized from a 4 % w/v SPI solution at 85 °C for durations of 12, 18, and 24 h, resulting in the formation of fibrils with 57 nm, 97 nm, and 250 nm, respectively. The formation of fibrils was confirmed through atomic force microscopy, CD-spectroscopy, and FTIR, which demonstrated a structural change from an alpha-helix-rich to a beta-sheet-enhanced configuration (as quantified by CD spectral deconvolution) during the fibrillation process. Electrospun CAMs were immersed in fibril-containing solutions for 2 and 5 min. Filtration assessments revealed that fibrils produced with a mean diameter of 57 nm and a 5 min immersion time achieved the highest sodium rejection rate ( 15.90 %) representing a greater than threefold increase compared to the unmodified control membrane, which exhibited a sodium rejection rate of 4.4 %. Contact angle measurements revealed that the incorporation of these smaller fibrils led to a significant enhancement in surface hydrophilicity, decreasing the contact angle from 136.1° to 73.3°. Although sodium rejection remained modest (15.9 %), the study demonstrates a proof-of-concept that soy protein fibrils can modulate membrane hydrophilicity and surface morphology. The approach shows potential as a pretreatment or ion-selective tuning strategy but requires further optimization for desalination applications.

The fermentation quality of High-temperature Daqu (HTD) shows marked heterogeneity, yet the underlying mechanisms driving these variations still require exploration. This study employed multidimensional technologies, including amplification sequencing and flavoromics, to investigate the quality differences among six typical HTDs from Guizhou Province and the driving mechanisms behind these variations. The result of physicochemical analysis indicates that the six HTDs show marked functional differentiation, such as the high fermentation/esterification type Daqu and the highly saccharified type Daqu. 19 specific microbial markers, including Weissella and Bacillus at genera level (linear discriminant analysis, LDA >4), were identified. The formation of these markers was found to be primarily influenced by average annual precipitation and maximum temperature of fermentation HTD. Flavoromics analysis identified 36 flavor markers in HTD, with pyrazines being the representative compound. Concurrently, 2,3-dimethyl-5-ethylpyrazine was confirmed as the pyrazine compound with the most marked sensory differences among six HTDs. Subsequent correlation analysis revealed that region-specific microbial markers (e.g. Weissella, Oceanobacillus, Bacillus, and Monascus) are closely linked to the formation of differences in key physicochemical indicators (e.g. acidity and esterifying power), as well as flavor compounds (e.g. pyrazines, alcohols, and aldehydes) among six HTDs. Preliminary findings from this study suggest that the different distributions of microbial communities resulting from climatic conditions and Daqu-making techniques were the primary drivers of heterogeneity in HTD quality. The clarification of this driving mechanism provides crucial scientific indication for the future targeted optimization of HTD quality through regulation of technical parameters and functional microbiota.

Salmonella is a major foodborne pathogen that poses a serious threat to global public health and economic stability. Timely and reliable detection of Salmonella is essential for the effective prevention of foodborne diseases. Herein, a novel ultrasensitive smartphone-based colorimetric aptasensor for Salmonella was reported, leveraging both the strong signal amplification capability of cascade signal amplification technology and the high efficiency of Zr@Cys-Cu dual-enzyme catalysis (with phosphatase-like and laccase-like activities). The exponential amplification (EXPAR) could be specific triggered by Salmonella to form single-stranded target DNA, which further initiated the catalytic hairpin reaction (CHA), leading to the coupling of Fe3O4 and Zr@Cys-Cu. After magnetic separation, the collected Fe3O4-Zr@Cys-Cu was used for colorimetric detection, and the final colorimetric signal was processed by a smartphone. The Fe3O4-Zr@Cys-Cu aptasensor demonstrated excellent sensitivity and specificity in detecting Salmonella, with a linear range of 3 × 10°-3 × 105 CFU/mL and a detection limit of 3 × 100 CFU/mL. The entire detection process can be completed within 2 h. The system demonstrates the ability to detect analytes in complex sample matrices. Coupled with the portability of smartphones, this aptasensor emerges as a powerful tool for point-of-care testing (POCT), holding broad application potential.

Dual-signal/dual-target strategies boost biosensor accuracy and efficiency. Herein, we integrated square wave voltammetry (SWV) with photoelectrochemical (PEC) techniques to develop a dual-signal biosensor for simultaneous detection of β-lactoglobulin (BLG) and Arachis hypogaea allergen 1 (Ara h1). HOF-101 and ferrocene acted as PEC and SWV signal generators, while G-quadruplex/hemin served as PEC amplifier. BLG triggered release of ferrocene-modified In1 (Fer-In1), which unfolded G-quadruplex-modified hairpin H1 to expose hemin-binding sites, forming G-quadruplex/hemin complex that amplified PEC signal; meanwhile, ferrocene's SWV signal positively correlated with BLG concentration. Ara h1 induced Fer-In2 release and its binding to H1, achieving analogous signal amplification. The biosensor showed good linearity for BLG (20–2000 ng/mL) and Ara h1 (20–200 ng/mL), with detection limits of 12 ng/mL and 14 ng/mL, respectively, providing a robust tool for multiplex allergen detection in food safety and clinical diagnostics.

The pervasive environmental contamination resulting from the indiscriminate application of pesticides necessitates the development of rapid and highly sensitive detection methodologies. In this study, a flexible three-dimensional surface-enhanced Raman scattering (3D-SERS) platform was developed by embedding morphologically optimized gold nanostars (GNS) into a porous bacterial nanocellulose (BNC) matrix. The BNC scaffold's mechanical flexibility, high surface area, and nanofibrillar network enabled analyte enrichment, while the sharp-tipped GNS generated intense electromagnetic hotspots via localized surface plasmon resonance. Through systematic optimization, BNC-GNS substrate exhibited high SERS performance, achieving low detection limits of 1.03 ng mL−1 for acetamiprid and 1.33 ng mL−1 for phoxim, alongside a wide linear range. The 3D-SERS platform demonstrated remarkable stability, with a signal variation RSD of only 2.61% over 35 days, and excellent batch-to-batch reproducibility (RSD = 2.93%). Furthermore, the practical applicability was validated by detecting pesticide residues in spiked corn and soy flour samples, achieving recoveries of 92.43–104.91% (RSD below 2.91%). This work provides a robust, flexible SERS solution for pesticide monitoring in environmental and food safety applications.
滥用农药造成的普遍环境污染要求发展快速和高度敏感的检测方法。在这项研究中，通过在多孔细菌纳米纤维素（BNC）基质中嵌入形态优化的金纳米星（GNS），建立了一个柔性的三维表面增强拉曼散射（3D-SERS）平台。BNC支架的机械灵活性、高表面积和纳米纤维网络使分析物富集，而尖端GNS通过局部表面等离子体共振产生强烈的电磁热点。通过系统优化，BNC-GNS底物具有较高的SERS性能，对啶虫脒和辛硫磷的检出限分别为1.03 ng mL−1和1.33 ng mL−1，且线性范围宽。3D-SERS平台表现出显著的稳定性，35天内信号变化的RSD仅为2.61%，批间重现性极佳（RSD = 2.93%）。通过对加标玉米和大豆粉样品中农药残留的检测，验证了该方法的实用性，回收率为92.43 ~ 104.91% （RSD < 2.91%）。这项工作为环境和食品安全应用中的农药监测提供了一个强大、灵活的SERS解决方案。

Microbial co-culture fermentation is a well-established strategy to enhance the quality of fermented foods. This study investigated the effects of a selected pigment-producing Bacillus velezensis YM-3 and Aspergillus oryzae MJ-2, used individually or in co-culture, on the physicochemical characteristics and flavor compounds of broad bean paste during a 30-day fermentation. The results showed that co-culture fermentation moderated the pH decrease and significantly increased the reducing sugar and amino acid nitrogen contents. Notably, co-culture with B. velezensis YM-3 brightened the reddish-yellow color of the broad bean paste. Metabolite analysis revealed that co-culture increased the production of lactic and malic acids while reducing oxalic and succinic acids. Furthermore, co-culture significantly increased the overall abundance of volatile flavor compounds, particularly esters and alcohols. The relative abundance of beneficial flavor metabolites, including 2-ethylphenol, 2,5-dimethylpyrazine, linalool, isobutyric acid 1-methylbutyl ester, and 1-phenyl-1-pentanone, were markedly enhanced, whereas undesirable compounds such as n-hexanal and phenol were reduced. These results demonstrate that co-culture fermentation with B. velezensis YM-3 and A. oryzae MJ-2 effectively improves the overall quality of broad bean paste, highlighting the potential of B. velezensis YM-3 as a starter culture for the fermented food industry.
微生物共培养发酵是提高发酵食品质量的一种行之有效的策略。本研究研究了一种产色素芽孢杆菌（Bacillus velezensis） m -3和米曲霉（Aspergillus oryzae MJ-2）单独或共培养在30天的发酵过程中对蚕豆酱理化特性和风味成分的影响。结果表明，共培养发酵减缓了pH的下降，显著提高了还原糖和氨基酸氮的含量。值得注意的是，与B. velezensis m -3共培养使豆沙的红黄色变亮。代谢物分析表明，共培养增加了乳酸和苹果酸的产量，同时减少了草酸和琥珀酸的产量。此外，共培养显著增加了挥发性风味化合物的总体丰度，特别是酯类和醇类。有益风味代谢物，包括2-乙基酚、2,5-二甲基吡嗪、芳樟醇、异丁酸1-甲基丁基酯和1-苯基-1-戊酮的相对丰度显著增加，而不良化合物如正己醛和苯酚的相对丰度则减少。综上所示，与扁豆芽孢杆菌m -3和米芽孢杆菌MJ-2共培养发酵能有效提高豆瓣酱的整体品质，突出了扁豆芽孢杆菌m -3作为发酵食品工业发酵剂的潜力。

Aquatic product preservation is increasingly threatened by spoilage bacteria, especially multidrug-resistant Pseudomonas aeruginosa. This study establishes a dual-action biocontrol strategy combining Lactiplantibacillus plantarum 103-1 cell-free supernatant (CFS) with lytic bacteriophage P37. The CFS, enriched in organic, phenolic, and short-chain fatty acids, inhibited P. aeruginosa PAO1 growth and reduced biofilm biomass by ∼62%. It also decreased pyocyanin and rhamnolipid levels by ∼20% and ∼23%, respectively. Phage P37 exhibited broad thermal (4–50 °C) and pH (4–11) stability and strong lytic activity, with a burst size of 185 plaque-forming units (PFU) per cell. Combined treatment with 10% CFS and P37 at a multiplicity of infection (MOI) of 0.001 eradicated PAO1 within 12 h and reduced perch bacterial load by 55% over 9 days at 4 °C, outperforming either treatment alone. The findings suggested that lactic acid bacteria (LAB) metabolites disrupted bacterial motility and biofilms, enhancing phage susceptibility and providing a sustainable alternative to chemical preservatives in aquatic product preservation.

Combined treatment with 10% CFS and P37 at a multiplicity of infection (MOI) of 0.001 eradicated PAO1 within 12 h and reduced perch bacterial load by 55% over 9 days at 4 °C, outperforming either treatment alone. The findings suggested that lactic acid bacteria (LAB) metabolites disrupted bacterial motility and biofilms, enhancing phage susceptibility and providing a sustainable alternative to chemical preservatives in aquatic product preservation.</div></div>","PeriodicalId":12409,"journal":{"name":"Food Bioscience","volume":"77 ","pages":"Article 108408"},"PeriodicalIF":5.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147399590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed a multifunctional biodegradable lignin-removed loquat peel film (LPF) via sodium alginate-based chemical oxidation and casting. Delignification enhanced mechanical strength (TS increased by 3.6 times, EAB increased by 15.1 times), optical transparency (progressive 350-800 nm transmittance), and barrier properties (WVP reduced by 70.3%). XRD, FT-IR and TGA analysis revealed cellulose formed strong hydrogen bonds with sodium alginate and glycerol, while delignification intensified these intermolecular interactions, accounting for the mechanical reinforcement. HPLC-TOF-MS2 identified 20 bioactive compounds (phenolics/terpenoids/fatty acids) enabling dual functionality: 58.46% DPPH and 64.72% ABTS scavenging, plus 99% bacterial inhibition (Escherichia coli and Staphylococcus aureus). Practical validation shows cantaloupe packaged with LPF could effectively extend the shelf life. The established protocol exhibits broad applicability for converting pectin/cellulose-rich biomass (e.g., grape skins, pomegranate rinds) into mechanically robust, functionally graded packaging materials. This work presents a novel strategy for designing sustainable cling film that ingeniously turns agricultural waste into a treasure, which not only unlocks a novel route for waste valorization but also provides an effective source-level solution to substitute conventional plastics and address plastic pollution.

Hawthorn fruit is prone to nutrient loss and oxidative deterioration during storage, which significantly reduces its commercial value. This study evaluated the impact of pulsed light (PL) treatment on the storage quality of hawthorn fruit. The results showed that a PL treatment dose of 600 – 700 J enhanced the content of total phenols, total flavonoids, and Vitamin C, while reducing PPO activity, increasing CAT activity, and facilitating the removal of H2O2 and MDA. By integrating metabolomics and transcriptomics analyses, it was found that PL treatment upregulated the expression of key genes such as ODC, ALDH, and GAD, thereby activating the arginine-putrescine-γ-aminobutyric acid (GABA) and glutamate-GABA metabolic pathways, and improving the antioxidant activity and maintaining postharvest quality of hawthorn. These findings provide a reference for clarifying the molecular mechanism by which PL treatment maintains the postharvest quality of fruit and vegetables.
