Peeling is critical in garlic processing, impacting product quality and economic efficiency. A pretreatment coupling water regulation with flexible extrusion was developed to improve pneumatic peeling efficiency, with its mechanism explored. Convective drying (40 °C/8 h) reduced peel moisture content to 10.3 % (wet basis), and subsequent flexible extrusion (10–15 N/7 s) treatment achieved a pneumatic peeling rate of 97.4 % with minimal quality deterioration. Water in the garlic peel cell wall was effectively removed during water regulation, disrupting the integrity of its polysaccharide network structure. Meanwhile, the mechanical strength of the peel and molecular weight of pectin were reduced. In addition, water removal damaged the epidermal wax layer and caused cellular contraction and collapse, thereby weakening the adhesion of the middle lamella. Furthermore, flexible extrusion induced cracks on the peel, facilitating peel fragmentation and removal. The results lay the groundwork for efficient peeling of irregular and thermosensitive agricultural products.

This study employed a Caco-2 intestinal model to evaluate the impact of soybean oil and its fatty acid constituents (oleic acid (OA), linoleic acid (LA), and linolenic acid (LNA)) on the intestinal absorption, transport, and toxicity of benzo[a]pyrene (BaP) and benzo[b]fluoranthene (BbF). Key findings demonstrated that dietary lipids significantly enhanced the bioavailability of polycyclic aromatic hydrocarbons (PAHs) through synergistic active-passive transport mechanisms. Specifically, oil carriers increased BaP absorption by 14–17 % and BbF absorption by 12–15 % compared to free PAHs. Lipid-carried PAHs induced concentration-dependent cytotoxicity characterized by progressive lipid accumulation, elevated oxidative stress, mitochondrial membrane potential collapse, and apoptosis. The carrier-mediated enhancement followed a consistent potency gradient: free PAHs < OA < LNA < LA < oil carriers, implying the synergistic effect of multiple fatty acids in the oil carrier. These findings establish a pathological cycle of lipid-enhanced PAH absorption → intestinal barrier damage → further PAH accumulation, providing the first experimental analysis of dietary lipid-mediated PAH bioavailability and direct evidence for assessing PAH exposure risks in lipid-rich foods.
本研究采用Caco-2肠道模型，评估大豆油及其脂肪酸成分（油酸（OA）、亚油酸（LA）和亚麻酸（LNA））对苯并[a]芘（BaP）和苯并[b]芴（BbF）肠道吸收、转运和毒性的影响。主要研究结果表明，膳食脂类通过协同主动-被动转运机制显著提高了多环芳烃（PAHs）的生物利用度。具体来说，与游离多环芳烃相比，油载体增加了14 - 17%的BaP吸收和12 - 15%的BbF吸收。脂质携带多环芳烃诱导浓度依赖性细胞毒性，其特征为进行性脂质积累、氧化应激升高、线粒体膜电位塌陷和细胞凋亡。载体介导的增强遵循一致的效势梯度：游离PAHs <； OA < LNA < LA <；油载体，说明油载体中存在多种脂肪酸的协同作用。这些发现建立了一个脂质增强的多环芳烃吸收→肠屏障损伤→多环芳烃进一步积累的病理循环，首次提供了饮食脂质介导的多环芳烃生物利用度的实验分析，并为评估富含脂质食物中多环芳烃暴露风险提供了直接证据。

Monascus azaphilone pigments (MPs) are widely used functional food additives. However, Monascus may simultaneously produce the mycotoxin citrinin (CIT), compromising MPs safety. Here, we used comparative genome, transcriptome, and quantitative data-independent acquisition mass spectrometry (DIA-MS) proteome analyses to compare three representative Monascus purpureus strains: M3 with high MPs and high CIT titers, M34 with high MPs and low CIT titers, and M69 with low titers of both products. Comparative genomic analysis confirmed high similarity among these strains. Differentially expressed genes (DEGs) and differentially abundant proteins (DAPs) were identified by pairwise comparisons among the strains during peak metabolite production, and selected DEGs and DAPs were verified by reverse transcription quantitative polymerase chain reaction and parallel reaction monitoring. An integrated analysis revealed DEG/DAPs correlating with altered MPs and CIT production, providing insights for strain breeding to engineer safer and more efficient MPs production processes in the food, cosmetics and pharmaceutical industries.

Aligning with the growing demand for salt reduction strategies and the need to protect food biodiversity, this study aims to develop healthy savory biscuit-like snacks with reduced sodium content. An ancient (Automonia B) and modern (Bolero) soft wheat variety were combined with various concentrations of salt (0 %, 1 %, 2 %) and glasswort powder (1 %, 4 %, and 8 %).
Physical and microstructural analysis revealed that Bolero samples exhibited significantly higher hardness values (76.88 ± 15.4 N) compared to Autonomia B (54.5 ± 11.5 N). However, hardness decreased in both varieties as the concentration of glasswort increased, reaching average values of 67.17 ± 5 N for Bolero and 41.6 ± 3.5 N for Autonomia B. The total porosity of Bolero snacks was lower compared to Autonomia B, but other microstructural attributes, e.g. structure thickness and separation, were closely linked to textural properties. Salt and glasswort concentrations significantly influenced the sensory properties of biscuits formulated with two wheat varieties, while visual attributes remained consistently acceptable. Saltiness perception was mainly driven by salt but was also significantly enhanced by glasswort, supporting its role as a natural “green salt” ingredient. Overall taste showed a non-linear response, with moderate salt and glasswort levels maximizing pleasantness. These results highlight glasswort as a promising strategy for sodium reduction without compromising sensory quality, offering an innovative, scalable and biodiversity-enhancing strategy solution for industry-driven salt-reduction programs.
为了适应不断增长的减盐战略需求和保护食物生物多样性的需要，本研究旨在开发低钠、健康可口的饼干状零食。古代（Automonia B）和现代（Bolero）软小麦品种与不同浓度的盐（0%,1%,2%）和玻璃草粉（1%，4%和8%）结合使用。物理和显微结构分析表明，Bolero样品的硬度值（76.88±15.4 N）明显高于Autonomia B（54.5±11.5 N）。然而，随着玻璃草浓度的增加，两个品种的硬度都有所下降，Bolero的硬度平均值为67.17±5 N， Autonomia B的硬度平均值为41.6±3.5 N。Bolero零食的总孔隙率低于Autonomia B，但其他微观结构属性，如结构厚度和分离度，与质地特性密切相关。盐和玻璃草浓度显著影响了用两种小麦制成的饼干的感官特性，而视觉特性保持一致。咸度感主要由盐驱动，但玻璃草也显著增强，支持其作为天然“绿色盐”成分的作用。整体口味呈非线性反应，适度的盐和玻璃草水平使愉悦感最大化。这些结果突出了玻璃草作为一种有前途的减钠策略而不影响感官质量，为工业驱动的减盐计划提供了一种创新的、可扩展的和增强生物多样性的策略解决方案。

Tilapia skin collagen peptides possess multiple biological functions, yet their potential value remains underdeveloped and underutilized. This study investigated the efficacy and mechanisms of tilapia skin collagen peptides (TSCPs) in mitigating aging. TSCPs significantly delayed aging progression in H2O2- and glucose-induced zebrafish models. Three tyrosinase-inhibitory peptides and five antiglycation peptides were identified in TSCPs through targeted screening. Specifically, peptides Ser-Glu-Gly-Lys (SEGK) and Asp-Asp-Asp (DDD) exhibited the strongest in vitro tyrosinase-inhibitory and antiglycation activity, respectively. Molecular dynamics simulations revealed that both peptides bound more stably to anti-aging targets (tyrosinase and receptor for advanced glycation end products (RAGE)) through hydrogen bonds and electrostatic interactions. Moreover, SEGK and DDD reduced reactive oxygen species (ROS), malondialdehyde (MDA), and advanced glycation end products (AGEs) levels in zebrafish models, thereby contributing to the preferable aging mitigation effects. These findings provide in-depth insights into the mechanisms by which TSCPs mitigate aging from the perspectives of antioxidation, antiglycation, and tyrosinase inhibition, offering a theoretical basis for the development of TSCPs-based functional foods.

Hafnia alvei, a predominant spoilage bacterium in aquatic products, regulates its spoilage phenotypes through an N-acyl homoserine lactone (AHL)-mediated quorum sensing (QS) system. Penicillin G acylase (PGA), an eco-friendly quorum-quenching enzyme, and chlorogenic acid (CGA), a natural polyphenolic compound with antioxidant and antibacterial properties, were investigated for their combined inhibitory effects on QS and biofilm formation in H. alvei. Results showed that the PGA-CGA combination exhibited strong biofilm inhibition (29.88 %–59.18 %) and clearance (30.61 %–55.45 %) compared to individual treatments. Scanning electron microscopy revealed that PGA-CGA disrupted biofilm architecture, yielding thinner structures and dispersed bacterial colonies. Furthermore, the combination significantly suppressed some spoilage phenotypes, including violacein production, extracellular polysaccharide synthesis, biogenic amine accumulation, siderophore secretion, lipase activity, and motility, with inhibition rates ranging from 28.94 % to 100 %. Real-time PCR analysis revealed that PGA-CGA synergistically downregulated QS-associated (halI and halR), biofilm-related (flgA), spoilage-related (dppF), and motility-related (motB and kdsD) genes by 30 %–60 %, surpassing the effects of individual treatments. Metabolomic profiling further demonstrated that the combination disrupted carbohydrate and energy metabolism, amino acid and nucleotide biosynthesis, and biotin metabolism. Additionally, the PGA-CGA reduced the levels of total viable counts and total volatile base nitrogen in salmon fillets, and maintained good sensory quality during 12 d of storage. Therefore, the PGA-CGA combination is proposed as a promising novel agent for fish preservation.

Chlortetracycline (CTC), a broad-spectrum veterinary antibiotic, poses serious risks to human health through bioaccumulation due to excessive use. To address the critical need for CTC monitoring, we developed a fluorescence quenching lateral flow immunoassay (FQ-LFIA) employing black bimetallic hollow nanoparticles (BBHNPs) as quencher. BBHNPs were engineered with a unique dual-advantage architecture: an internal hollow structure for enhanced light capture capability and an external polydopamine layer for higher spectral overlap with fluorophores. This design resulted in exceptional photophysical characteristics, including a remarkable molar extinction coefficient (2.18 × 1012 L mol−1 cm−1) and an unprecedented fluorescence quenching constant (5.20 × 1013 L mol−1). BBHNP-based FQ-LFIA achieved a limit of detection (LOD) of 0.32 ng mL−1, representing a 6.91-fold improvement over conventional gold nanoparticle-based lateral flow immunoassay (LFIA). Validation studies in spiked milk samples showed excellent recovery rates (87.73–118.09 %) with high precision (coefficient of variation <10.36 %). Method comparison with liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis confirmed the reliability of BBHNP-FQ-LFIA for real-world applications.
氯四环素是一种广谱兽用抗生素，由于过量使用，会通过生物积累对人类健康造成严重危害。为了满足CTC监测的迫切需求，我们开发了一种荧光猝灭横向流动免疫测定（FQ-LFIA），采用黑色双金属空心纳米颗粒（BBHNPs）作为猝灭剂。BBHNPs具有独特的双重优势结构：内部中空结构增强光捕获能力，外部聚多巴胺层与荧光团具有更高的光谱重叠。这种设计产生了卓越的光物理特性，包括显著的摩尔消光系数（2.18 × 1012 L mol−1 cm−1）和前所未有的荧光猝灭常数（5.20 × 1013 L mol−1）。基于bbhnp的FQ-LFIA的检测限（LOD）为0.32 ng mL−1，比传统的基于金纳米颗粒的横向流动免疫分析法（LFIA）提高了6.91倍。对加标牛奶样品的验证研究表明，加标回收率为87.73 ~ 118.09%，精密度高（变异系数为10.36%）。方法与液相色谱-串联质谱（LC-MS/MS）分析的比较证实了BBHNP-FQ-LFIA在实际应用中的可靠性。

Inflammation is a natural immune response to injury, infection, or harmful stimuli. While it is essential for host defense, chronic or excessive inflammation can lead to tissue damage and is implicated in diseases such as inflammatory bowel disease, gout, hyperuricemia nephropathy, and various pulmonary, hepatic, and neurological disorders. Certain oligopeptides, particularly those containing valine and proline, exhibit anti-inflammatory properties. Marine-derived oligopeptides are also known to possess diverse bioactive effects, including anticancer, antioxidative, and anti-inflammatory activities. In this study, an oligopeptide with the sequence CGQCPVS was cyclized via disulfide bond formation using the solid-phase peptide synthesis method. The cyclized peptide was analyzed and compared to its linear form using bioinformatics tools and molecular docking techniques to assess binding efficiency with key inflammatory proteins, including NLRP3, AIM2, Caspase-1, and IL-1β. The cyclized peptide exhibited reduced binding affinity to the NACHT domain of the NLRP3 inflammasome, comparable to MCC950, a known NLRP3 inhibitor. In vitro studies on the HCT116 epithelial cell line demonstrated high cell viability and a reduction in inflammatory markers at a 50 μM concentration. Further, the cyclized peptide downregulated proteins involved in the inflammatory pathway, including pro-inflammatory cytokines, effectively suppressing inflammation. These findings suggest that the cyclized oligopeptide holds potential as a pharmaceutical agent to mitigate NLRP3 inflammasome-associated inflammation and may serve as a promising candidate for developing novel anti-inflammatory therapies.

While it is essential for host defense, chronic or excessive inflammation can lead to tissue damage and is implicated in diseases such as inflammatory bowel disease, gout, hyperuricemia nephropathy, and various pulmonary, hepatic, and neurological disorders. Certain oligopeptides, particularly those containing valine and proline, exhibit anti-inflammatory properties. Marine-derived oligopeptides are also known to possess diverse bioactive effects, including anticancer, antioxidative, and anti-inflammatory activities. In this study, an oligopeptide with the sequence CGQCPVS was cyclized via disulfide bond formation using the solid-phase peptide synthesis method. The cyclized peptide was analyzed and compared to its linear form using bioinformatics tools and molecular docking techniques to assess binding efficiency with key inflammatory proteins, including NLRP3, AIM2, Caspase-1, and IL-1β. The cyclized peptide exhibited reduced binding affinity to the NACHT domain of the NLRP3 inflammasome, comparable to MCC950, a known NLRP3 inhibitor. <em>In vitro</em> studies on the HCT116 epithelial cell line demonstrated high cell viability and a reduction in inflammatory markers at a 50 μM concentration. Further, the cyclized peptide downregulated proteins involved in the inflammatory pathway, including pro-inflammatory cytokines, effectively suppressing inflammation.

Achyranthes japonica Nakai (USL) is a traditional medicinal plant with known antioxidant and anti-inflammatory properties; however, its efficacy against dry eye disease (DED) remains unclear. This study investigated the protective effects of USL against DED using an integrated network pharmacology and experimental approach. Chemical constituents of USL were identified by HPLC–MS, and network pharmacology analysis revealed 96 common targets shared between USL and DED, including 30 hub targets primarily associated with inflammasome activation and apoptosis-related pathways. Molecular docking analysis demonstrated favorable binding affinities between major USL constituents and key inflammatory proteins, including NLRP3 and caspase-3.
In vitro, USL significantly suppressed hyperosmolar stress–induced NF-κB activation and reduced the expression of pro-inflammatory cytokines, including IL-1β, TNF-α, MMP9, IL-33, and IL-13, in human conjunctival cells (n = 3). In vivo, oral administration of USL (100 and 250 mg/kg) significantly improved ocular surface parameters in a rat model of DED (n = 7 per group), increasing tear volume from 2.75 ± 1.25 to 5.60 ± 1.36 mm (p < 0.05), restoring conjunctival goblet cell density from 201.7 ± 46.9 to 267.1 ± 46.3 cells/100 μm (p < 0.05), and alleviating corneal surface irregularities. In addition, USL markedly reduced inflammatory markers, including MPO, CXCR1, NLRP3, and IL-17, in conjunctival tissues.
Taken together, these findings demonstrate that USL exerts protective effects against DED by modulating inflammatory and apoptotic pathways, particularly through regulation of inflammasome-associated signaling, and may serve as a promising plant-derived functional ingredient for improving ocular surface health.

To investigate the aroma divergence between Lentinula edodes strain 808 and its mutant ww808, this study combined gas chromatography–ion mobility spectrometry (GC–IMS) with multivariate analysis to compare their volatile organic compound (VOC) profiles during fruiting body development. Integrated analyses of dynamic fatty acids, lipoxygenase (LOX) pathway enzymes, and gene expression were conducted. The results indicated that differences in eight-carbon (C8) compounds, aldehydes, and alcohols underlie their distinct aroma profiles. C18:1n9 and C18:2 were important aroma precursors. Although ww808 exhibited higher C18:2 levels, its LOX gene expression and enzyme activity were generally lower than those in strain 808 during the growth process, resulting in a limited downstream conversion efficiency of aroma precursors through the LOX pathway in this strain. Concurrently, the expression levels of alcohol dehydrogenase genes (ADHs) (especially ADH3 and ADH4) in ww808 were significantly upregulated during the later stage of fruiting body growth, facilitating the efficient conversion of aldehydes into alcohols and ketones with higher odor thresholds. This was typically reflected by the higher abundance of aldehydes such as hexanal-D and butanal in strain 808 during the maturation stage, whereas ww808 accumulated more alcohol/ketone compounds such as 3-methyl-1-butanol-D and 2-methyl-3-heptanone. The generally higher odor thresholds of alcohols contributed to the reduced aroma intensity in ww808. This study revealed the regulatory network of aroma formation in L. edodes at the levels of metabolites, precursors, and genes, providing a theoretical foundation and potential candidate genes for the directional improvement of aroma quality.
