The use of artificial sweeteners is becoming increasingly common. High-fructose corn syrup (HFCS) and aspartame are the two most commonly used sweeteners. It is reported that their consumption was associated with the impairment of cognitive function. However, the specific mechanism whereby HFCS and aspartame diets influence cognitive function is still unclear. Here, we administered 20% HFCS and 50 mg/kg aspartame in drinking water to establish a dietary intervention, and assessed mouse cognitive function using the novel object recognition (NOR) experiment. Results showed that the cognitive function of the mice declined in the NOR experiment. In order to clarify the molecular mechanisms, the Oxford Nanopore Technologies (ONT) platform was used to perform full-length RNA sequencing. As a result, 662 long non-coding RNAs (lncRNAs) and 6895 alternative splicing (AS) events were identified, and the enrichment results of differentially expressed lncRNA target genes and AS genes suggested that the pathways related to cellular autophagy were enriched. The western blotting showed the PI3K/AKT/mTOR signaling pathway was activated, and the results of immunofluorescence also suggested that the HFCS and aspartame intake induced the accumulation of amyloid-β in the hippocampus. All in all, our study, starting from the dimensions of lncRNAs and AS, has deeply analyzed the potential mechanisms underlying the cognitive decline in mice caused by the intake of aspartame and HFCS, and put forward possible and novel insights.

Flavor compounds (FLVs) directly affect the consumer acceptance of food while also contributing to health by modulating the gut microbiota. In this work, we will review the most recent studies on the effects of FLVs on gut microbiota. Particularly, the key findings from the animal studies associated with the major FLVs such as flavonoids, phenolics, carboxylic acids, and others are collected and tabulated. The relationship between structure of flavor compounds and their modulation mechanisms is highlighted. The challenge and direction for future studies are also proposed. This review could provide a foundational understanding of the multifaceted interactions among FLVs, gut microbiota, and host health, which may guide the development of FLVs in the functional foods.

Bovine colostrum (BC), valued for its nutrient density and bioactive compounds, demands preservation techniques that retain these beneficial properties, driving interest in non-thermal approaches such as atmospheric cold plasma (ACP). This study assesses ACP's impact on the physicochemical, microbiological, and structural properties of raw BC using a continuous-flow dielectric barrier discharge (DBD) reactor at 30 kV and 3.5 kHz for 15 and 30 min, within 20–25 °C. Optical emission spectroscopy (OES) identified a predominance of reactive nitrogen species (RNS) within the plasma discharge. ACP treatment achieved a 60 % reduction in Escherichia coli populations after 30 min (p < 0.05). Analysis of lipid hydroperoxides (A500 ≈ 0.043), total protein content (≈69.1 %), lactose levels (≈1.7 %), chromaticity indices (a∗ ≈ −4.18, b∗ ≈ 18.87), browning index (A420 ≈ 0.012), and viscosity (≈0.55 Pa s at a shear rate of 0.1 s−1) showed no statistically significant alterations (p > 0.05), indicating minimal oxidative or rheological impact, though a significant decrease in lightness (L∗, p < 0.05), suggested a slight darkening. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed stable profiles of proteins in BC after ACP treatment, including immunoglobulin G, β-lactoglobulin, α-lactalbumin, lysozyme, lactotransferrin, and bovine serum albumin, whereas circular dichroism (CD) spectroscopy detected significant secondary structural shifts, characterized by increased α-helix, parallel β-sheet, and turn conformations, alongside reductions in antiparallel β-sheet content and the emergence of distinct conformational domains. These findings affirm ACP as an effective non-thermal alternative, underscoring its potential to enhance BC preservation through microbial control and the retention of key proteins, while revealing secondary structural modifications that require further exploration of their functional impact on BC.

Citrus limon (L.) Osbeck and Citrus limetta Risso are widely consumed citrus fruits with important roles in functional foods and traditional medicine. Despite their close botanical linkage and phytochemistry involving D-limonene, C. limetta remains comparatively under-characterized and is often misclassified as a synonym of C. limon, which often leads to taxonomic ambiguity. This review compares both species critically with emphasis on functional phytochemicals, biological mechanisms, and emerging applications in nutraceuticals. While C. limon is extensively documented, available research indicates that C. limetta exhibits distinct metabolite profiles and promising antioxidant and anti-inflammatory potential that remain insufficiently explored. Differences in phytochemical distribution, bioactivity pathways, and translational relevance are discussed in the context of functional food and citrus waste valorization. Finally, an integrated framework incorporating phytochemistry and Artificial Intelligence-based foodomics is proposed to guide future research and evidence-based utilization of citrus species.

Dictyophora indusiate (DI) contains numerous bioactive compounds with immunomodulatory properties. However, the functional activities of its protein hydrolysate and their mechanisms of action in the regulation of systemic and intestinal mucosal immunity remain poorly understood. This study comprehensively evaluated the immunomodulatory potential of D. indusiate peptide hydrolysate (DIPH) using a multi-omics approach. LC-MS/MS analysis showed that DIPH is composed of peptides containing 8 to 20 amino acid residues, with branched-chain amino acids comprising 20.53 % of the total, and exhibits primarily hydrophobic properties. In cyclophosphamide-induced immunosuppressed mice, DIPH exhibited broad restorative effects on immunity via three interrelated mechanisms. Firstly, systemic immune function was enhanced, as demonstrated by significant elevations in serum IgG and IgM levels, and an improvement (4.5-fold) in carbon clearance capacity. Secondly, intestinal barrier integrity was strengthened through the upregulation of tight junction proteins, a 24.7 % rise in goblet cells, and a 1.11-fold increase in secretory IgA production. Thirdly, DIPH administration modulated gut microbiota composition, significantly enriching beneficial bacteria including Bifidobacterium and Roseburia while reducing Streptococcus, which was accompanied by a 2.1-fold increase in butyrate production. At the molecular level, DIPH exerted its effects through dual regulatory mechanisms: suppression of the TLR4/MyD88/NF-κB pathway and activation of FoxO1-mediated mucosal restoration. These insights collectively establish DIPH as a multi-target edible fungi-derived immunomodulator that uniquely integrates gut microbiota regulation, systemic immune enhancement, and intestinal barrier restoration, highlighting its promising applications in functional food development and microbiome-targeted therapies.

Oral processing is the first step in food digestion, thereby affecting the later steps of gastric and intestinal digestion. In vitro digestion systems have been developed that can recreate certain conditions of gastric and intestinal digestion. However, obtaining physiologically accurate results of bioaccessibility or gastric emptying requires starting with a bolus that contains a realistic particle size distribution. Oral processing simulators have been developed that can produce realistic boluses, but they have not yet become part of the majority of in vitro gastrointestinal digestion workflows. In this mini review, we highlight recent literature showing how oral processing affects the particle size distribution of food in the swallowed bolus and then call attention to results showing how the size distribution of food particles affects variables such as gastric emptying and bioaccessibility from both in vitro and in vivo research. Overall, results of these previous studies have established that oral processing has profound implications for physiological response during later stages of digestion. In view of this, we propose that oral processing simulators should be developed specifically for the purpose of integration with in vitro digestion systems. Furthermore, we identify challenges and design criteria to guide the development of oral processing simulators that could improve the accuracy of results from in vitro digestion experiments while preserving the advantages of in vitro research.

This research tackles the challenge of optimizing the fabrication and characterization of fava bean protein (FBP) nanofibers using electrospinning, evaluating the influence of varying blend ratios with polyvinyl alcohol (PVA) (PVA: FBP of 4:1, 7:3, and 1:1) on their physicochemical and functional properties. Scanning electron microscopy revealed that optimal fiber morphology, characterized by uniform and bead-free structures, was achieved at PVA: FBP ratios of 4:1 and 7:3. In contrast, the 1:1 ratio resulted in significant bead formation, a phenomenon correlated with a decrease in solution viscosity confirmed by rheological analysis. Fourier-transform infrared spectroscopy (FTIR) and Sodium Dodecyl Sulfate-Polyacrylamide (SDS-PAGE) verified the effective physical integration of FBP into the PVA matrix through hydrogen bonding interactions, rather than chemical crosslinking, without affecting the protein structure. Furthermore, circular dichroism analysis indicated that the electrospinning process induced a significant conformational shift within the secondary structure of the protein, favoring the formation of β-sheets over α-helices. Despite a less uniform morphology, the 1:1 composite retained 55 % residual mass, indicating significant char formation, and exhibited the most robust antibacterial efficacy against E. coli and S. aureus. Antioxidant capacity was found to be directly proportional to the FBP concentration in the nanofibers. These findings demonstrate that PVA-FBP composite nanofibers are successfully formed with promising biodegradable materials with tunable properties. The ability to balance structural integrity with enhanced thermal, antimicrobial, and antioxidant functionality by adjusting the blend ratio highlights their significant potential for advanced applications in active food packaging and preservation systems.

This study evaluated the antibacterial activity and mechanism of hepcidin-derived peptide from Plectorhinchus cinctus (Pc-hepcidin) against Vibrio parahaemolyticus. The obtained results showed that Pc-hepcidin exhibited strong antibacterial activity against V. parahaemolyticus with a minimum inhibitory concentration (MICs) at 0.313 mg/mL. Scanning and transmission electron microscopy analyses revealed pronounced membrane disruption, cellular deformation, and cytoplasmic leakage in V. parahaemolyticus upon Pc-hepcidin treatment. Consistently, elevated alkaline phosphatase activity and nucleic acid release further indicated compromised membrane integrity. In addition, Pc-hepcidin suppressed the activities of Na+/K+-ATPase and Ca2+-ATPase, thereby potentially disrupting ion transport and energy metabolism. Integrated transcriptomic and metabolomic profiling identified 218 differential metabolites and 2406 differentially expressed genes, primarily associated with cell wall synthesis (dacC, lpxL), purine metabolism, and DNA replication (ligA). Overall, these findings suggest that Pc-hepcidin exerts its antimicrobial effects through multiple pathways, highlighting its potential as a novel candidate for food preservation and therapeutic applications.

Solid-state fermentation (SSF) is a biotransformation process in which fungal mycelia degrade grain matrices under low-moisture conditions, thereby improving nutritional value and enriching functional compounds. This study investigated the effects of SSF using Peckorumyces umbonatus on the total phenolic content (TPC), total flavonoid content (TFC), and in vitro antioxidant activities of corn, rice, and wheat. An integrated approach combining LC-MS/MS-based untargeted metabolomics, network pharmacology, and molecular docking was employed to elucidate the key antioxidant compounds and underlying potential mechanisms. The results demonstrated that P. umbonatus fermentation significantly increased TPC and TFC, and enhanced DPPH· and ABTS·+ radical scavenging capacities across all grains. Notably, the fermented wheat exhibited the most superior improvement. Further analysis identified ten key antioxidant compounds; six were common to all groups, while four were exclusive to the wheat substrate. These compounds were predicted to exert antioxidant effects primarily via the PI3K/AKT signaling pathway. Molecular docking study confirmed that N-dihydrocaffeoylputrescine, [7]-paradol, and naringin dihydrochalcone exhibited the strongest binding affinity to the core target, AKT1. In conclusion, SSF with P. umbonatus significantly boosts the antioxidant properties of cereal grains, particularly in wheat substrates, providing a theoretical basis and technical support for developing functional grain products based on fungal fermentation.

Conventional processing methods for the edible-medicinal herb Polygonatum cyrtonema often lead to the degradation of its bioactive components, necessitating innovative techniques to enhance its quality and efficacy. This study aimed to investigate physicochemical properties of Polygonatum cyrtonema processed via steaming cycles coupled with freeze-drying and to explore the antidiabetic mechanisms using network pharmacology. Results revealed that the F4 group (4 steaming cycles and freeze-drying) significantly enhanced bioactive components. The saponins, flavonoids, and polyphenols contents increased by 329.13 %, 41.72 %, and 83.33 %, respectively, while oxalate decreased by 25.50 %. Volatile analysis showed F4 group retained more fresh aldehydes (e.g., nonanal, hexanal). Network pharmacology identified 118 key targets from 70 active components (e.g., quercetin, baicalein) intersecting with diabetes-related genes, primarily regulating IL-6, AKT1, and TNF via PI3K-Akt and AGE-RAGE pathways, as validated by molecular docking. Optimized Polygonatum cyrtonema powder (solid-liquid ratio of 1:33, 55 °C, 64.67 min) achieved 6.52 mg/g flavonoid, inhibiting α-amylase (78.61 %) and α-glucosidase (81.34 %) at 10 mg/mL through competitive and mixed-type inhibition. These findings demonstrate the synergistic processing advantages and multi-target antidiabetic mechanisms of the compound formulation.
