Proton exchange membranes (PEMs) attract attention for their tunable proton-conducting channels, but building effective transport networks and improving long-term stability in composites remain key challenges. In this study, a novel SPI composite PEM reinforced with 1,3-propane sultone-modified MXene/halloysite nanotube (SMH) fillers was successfully prepared. Systematic material characterization and performance tests revealed that the incorporation of SMH fillers significantly improved the physicochemical properties of the membrane. Moreover, the –SO 3 H groups on SMH and the –NH 2 groups on APTES can form hydrogen bonds and acid–base pairs with the –SO 3 H groups on SPI, thereby enhancing the tensile strength and proton conductivity of the composite film. The composite membrane exhibited a tensile strength of 80.3 MPa and a proton conductivity of 313.9 mS cm −1 (80 °C, 100% RH), representing 26.2% and 29.5% enhancements compared to the pristine SPI membrane, respectively. It assembled fuel cell with the SPI-2SMH composite membrane demonstrated a maximum power density of 259.1 mW cm −2 . More importantly, the radical scavenging effect of the variable-valence metal ions in MXene endowed the composite membrane with improved long-term stability under fuel cell operating conditions, extending the open-circuit voltage decay time to 3.3 times that of the pure SPI membrane. This study provides a new strategy for developing PEM materials with both high proton conductivity and enhanced durability for fuel cell applications. Graphical abstract

In order to solve the problem of coal mine fires caused by spontaneous combustion of coal, which often occurs during coal production, a new type of tea polyphenol-melamine formaldehyde resin-soy protein isolate (TP-MF-SPI) flame-retardant microcapsule was prepared by in situ polymerization in this paper. This is a flame-retardant microcapsule with tea polyphenol (TP) and MgCl2 as the core material and soy protein isolate (SPI)-modified diamine resin as the wall material. When the coal samples were oxidized and decomposed rapidly due to the temperature increase and slowly entered into the combustion stage, the coal samples with added core and microencapsulated materials have increased several important temperature points compared with the original coal. From the simultaneous thermal analyzer experiments, it was concluded that the temperature point of the mass maxima by 1.3℃ and 4.7℃, the ignition temperatures by 1.6℃ and 4.1℃, and the temperature point of the maximal loss rate by 3.7℃ and 12.3℃. It can be seen that the use of microencapsulation technology for magnesium chloride-tea polyphenol coating can be more effective in prolonging the flame-retardant life of the core material in the high temperature stage of the coal samples, and to enhance its flame-retardant effects. The performance test of microencapsulated flame retardant using cone calorimeter experiment and thermal stability analysis experiment showed that the peak heat release rate of the original coal samples and the coal samples with 1:5, 1:4, 1:3 flame retardant additions were 72.54 kW/m2, 55.17 kW/m2, 35.99 kW/m2, 30.31 kW/m2. Through the different ratios of microcapsule material coal samples show the effect of flame retardant effect and the cost of a comprehensive comparison and analysis, to determine the 1:4 microcapsule material additive amount can play the best flame retardant effect on the coal sample.

A compact in-trap single photon ionization (SPI) system, termed discontinuous atmospheric pressure interface (DAPI) ion trap mass spectrometry (ITMS), for the rapid determination of trace volatile organic compounds (VOCs). DAPI enables the maintenance of high analyte pressure in the SPI source while preserving the vacuum. Utilizing vacuum ultraviolet (VUV) lamp as the ion source, we ionize the analyte within an enclosed miniature 3D ion trap for efficient analysis. Experimental findings demonstrate that the system achieves a mass resolution of less than 0.5 atomic mass units for full width at half maxima (FWHM), providing unit resolution. For the response for benzene, the system achieves almost instantaneous response, with rise and fall times of only 2 s, which is a significant advantage compared to the membrane inlet (MI) approach necessary for on-site detection. Additionally, tandem mass spectrometry (MS/MS) with unit m/z isolation window was achieved and resolved dimethyl disulfide and phenol with similar molecular weights. Our results demonstrate that the system provides excellent performance and we anticipate its application in rapidly determining VOCs.

To address the problem of low algae oil utilization in the food industry, the researchers prepared algal oil powder with high loaded content (62 %) and stable encapsulation (75 % encapsulation efficiency) by using soybean isolate protein (SPI), cellulose nanocrystals (CNCs), type A gelatin (AG, pI = 7–8) and sodium hexametaphosphate (SHMP). Meanwhile, characterized the properties of the emulsions and the physical indicators of the oil powder. Study shown that the formed CNCs-SPI composite improved the rheological properties and charge intensity (−35 mV) of the emulsion. After adding AG and SHMP to the CNCs-SPI stabilized emulsion, the electrostatic self-assembly of the wall materials were achieved by utilizing the differences in charge properties between particles. The results of Fourier transform infrared spectroscopy indicated that these colloidal particles were composited through hydrogen bond and electrostatic interactions. Compared with SPI oil powder, these polyelectrolyte particles significantly improved the structure of the oil powder after spray drying. Through the formation of a dense and complete encapsulation, it not only reduced the surface oil content by 42.28 %, but also increased the glass transition temperature by 30.85 %. This study provides a feasible method for the preparation of high loaded oil powders and offers a new strategy for emulsion microencapsulation.

Fucoxanthin (FUC), a lipid-soluble carotenoid with various bioactivities, demonstrates promise as a preventive agent against inflammatory bowel disease (IBD). Nevertheless, the inherent instability and low aqueous solubility of FUC limit its application in functional food formulations and pharmaceutical applications. In this study, a FUC-loaded pickering emulsion (G-SPI-COS/FUC emulsion) with high encapsulation efficiency and small particle size was developed by using genipin-crosslinked soy protein isolate (SPI)-chitooligosaccharide (COS) nanoparticles as stabilizers. G-SPI-COS/FUC emulsion exhibited excellent stability under varying pH values, ionic strengths, and storage conditions. In vitro digestion experiments showed that G-SPI-COS/FUC emulsion controlled FUC release and enhanced its intestinal absorption and bioavailability. Furthermore, G-SPI-COS/FUC emulsion was more effective in preventing dextran sulfate sodium (DSS)-induced colitis than free FUC and FUC-loaded pickering emulsion stabilized by native SPI. These findings indicated that G-SPI-COS/FUC emulsion could serve as a promising delivery system for FUC, providing a novel approach to the prevention of IBD.

Hemin is recognized as a superior biological iron-fortifier in the prevention and treatment of iron deficiency anemia . Nevertheless, free hemin could have low bioavailability due to its insolubility in intestinal fluid after passing through the digestive tract, so hemin as a direct fortifier is not as effective as it should be. In this study, a novel hemin-delivery system with good water-solubility was developed by fabricating soy protein isolate (SPI)-hemin complex nanoparticles through pH-driven method, and the formation mechanism and bioavailability were also investigated. Hemin could bind to SPI and form nanoparticles with a diameter ranging from 100 to 300 nm in the process of pH dropping from 12.0 to 7.0, and thereby significantly improve the water-solubility of hemin. It was proved that the nanoparticles were produced mainly through hydrophobic interaction between SPI and hemin, and driven by entropy. The results from in vitro simulated gastrointestinal digestion experiments indicated that bioavailability of hemin was also significantly improved (P < 0.05), and the value in SPI-hemin nanoparticles reached nearly 80% at the concentrations of 1.0% (w/v) SPI and 0.25% (w/v) hemin. SPI-hemin nanoparticles could be an innovation for improving the solubility and bioavailability of hemin and an easily acceptable candidate for the design of novel iron-fortified foods.

Chitosan (CS) and polylactic acid (PLA) are both commonly used packaging materials in the food industry. However, a bilayer film made from CS and PLA, simultaneously incorporated with a complex essential oil-loaded Pickering emulsion (PE) system, have not been widely investigated. Therefore, this study designed bilayer films consisting of PLA layer and a PE layer. In the PE layer, binary nanoparticles composed of soybean protein isolate (SPI) and CS were used as solid supports to load increasing amounts (0 %, 2 %, 4 %, 6 %, 8 %, v/v) of complex essential oils (carvacrol and thymol, CT). The films were labeled BF-CT0, BF-CT2, BF-CT4, BF-CT6, and BF-CT8. The characteristics and functional properties were evaluated, along with the quality changes in refrigerated pork wrapped with the films (BF-CT0 or BF-CT8). Results indicated that CT addition significantly enhanced the stability of the PE. The PE layer with higher CT doses exhibited a denser microstructure, more hydrophobic surface, improved elongation at break, and greater water resistance. CT addition significantly improved light and gas barrier functions. Notably, the BF-CT8 film demonstrated extremely low water vapor and oxygen permeability (1.25 ± 0.06 kg•m⁻¹•s⁻¹•Pa⁻¹ and 0.24 ± 0.01 kg•m⁻¹•s⁻¹•bar⁻¹, respectively). All films showed a similar semi-crystalline structure, and CT addition decreased crystallinity. As expected, BF-CT8 displayed enhanced antioxidant and antibacterial performance. Finally, BF-CT8 extended the shelf life of refrigerated pork from 3 days to 6 days compared to BF-CT0 and unwrapped pork. In conclusion, the bilayer film shows great potential for use in pork preservation.

Fabrication of new 3D scaffold based on sodium alginate (SA), polyvinyl alcohol (PVA), sesame protein isolate (SPI) and Zinc nanoparticles (ZnNPs) has been prepared. SPI was extracted and evaluated via its amino acid composition, solubility, and antioxidant activity. The scaffolds were formulated with different ratios of SA/PVA/Zn/SPI and investigated via different instruments FTIR, XRD and SEM/EDX. Additionally, the effect of the scaffold on the hepato-protection and immune-stimulating in methotrexate (MTX) treated rats has been studied. The results showed that SPI rich in Arginine (21.33 %), Histidine (15 %), Aspartic acid (12.7 %) and Glutamic acid (9.69 %). SPI exhibited higher solubility and antioxidant activity at pH 7 (47.55 and 87.23 %) when measured by DPPH and ABTS methods respectively. SPI and Zn have the ability to mitigate the effects of MTX on body weight loss. SA/PVA/ZnNPs and SA/PVA/ZnNPs/SPI scaffolds have potential liver protection by down-regulating liver functions (34.83 ± 1.17 U/L and 27.83 ± 1.08 U/L, respectively for ALT and 53.00 ± 1.15 U/L and 48.29 ± 1.29 U/L, respectively for AST) and oxidative and inflammatory markers (MDA, IL-6, IL-1β, and TNF-α) and up-regulating liver antioxidant enzymes (GPx and SOD). Furthermore, the immune-enhancing effects of SA/PVA/ZnNPs and SA/PVA/ZnNPs/SPI scaffolds were demonstrated by the reduction in INF-γ (33.17 ± 0.94 pg/mL and 27.73 ± 0.68 pg/mL, respectively) and CD 8 (381.5 ± 2.56 pg/mL and 337.8 ± 1.87 pg/mL, respectively) levels and the elevation in CD 4 /CD 8 ratio (1.79 ± 0.02 and 3.00 ± 0.01, respectively) comparable to the MTX group (41.25 ± 0.85 pg/mL, 531.7 ± 2.56 pg/mL and 0.99 ± 0.005, respectively). Thus, the scaffold may have a role in liver protection and immune enhancement.

Transglutaminase (TGase)-mediated cross-linking has gained significant attention due to its potential to reduce the allergenicity of food proteins. This study investigates the effects of TGase cross-linking on allergenicity and conformational modifications in a dual-protein system comprising soy protein isolate (SPI) and β-lactoglobulin (β-LG). The results showed that TGase cross-linking effectively decreased the allergenic potential of both SPI and β-LG, with a more pronounced reduction observed in the allergenicity of soy protein in the dual-protein system. SDS-PAGE analysis revealed that the 7S and 11S subunits of soy protein were more easily cross-linked than β-LG. Secondary structure analysis indicated that TGase treatment disrupted β-sheet structures, increased the content of random coils, and enhanced protein flexibility. Ultraviolet absorption and intrinsic fluorescence analyses confirmed these structural alterations, with TGase treatment exposing additional aromatic amino acids. A reduction in free sulfhydryl groups and altered intermolecular forces further corroborated the occurrence of cross-linking. These findings suggest that TGase-mediated cross-linking effectively reduced the allergenicity of SPI and β-LG by modifying their conformations, offering potential strategies for the development of hypoallergenic dual-protein food products. Practical Application This study has practical applications in the food industry to develop hypoallergenic food products, particularly those that combine soy and dairy proteins. By using TGase to cross-link these proteins, the allergenicity can be reduced, resulting in products that are safer for consumers with food allergies.

In recent years, with the aggravation of plastic pollution and the enhancement of people's awareness of environmental protection, biodegradable active films have attracted wide attention. Based on the phase separation behavior of plant protein, active films with excellent mechanical properties and barrier properties can be tailored. In this study, a new type of zein/soybean protein isolate (SPI) active film via heteroprotein phase separation was prepared. We have innovatively transformed SPI self-supporting gels into highly lubricating microgels to prepare the film matrix, and filled it with zein nanoparticles and zein coacervate, respectively. Hydrophilic SPI and hydrophobic zein were used to achieve the co-encapsulation of Epigallocatechin-3-gallate (EGCG) and α-tocopherol. The composite films showed different phase separation modes, morphology and microstructure after solvent evaporation. The mechanical properties of the composite films containing different zein fillers were improved, meanwhile, the permeability of water vapor and oxygen was significantly reduced. The composite films with excellent antibacterial and antioxidant properties slowed down the oxidation of fresh-cut apples. This study offers a novel approach for advancing the development of plant protein-based active films.

This study investigates the binding capacity and mechanism of flash-evaporation-treated SPI with 2-acetylfuran at 75–130 °C. SPME-GC/MS, spectroscopic methodologies, FRET, and ITC are used to estimate binding ability. The highest binding percentage (89.17 %) is observed at 100 °C. The conformational changes of flash-evaporation-treated SPI reveal that 100SPI exhibits the highest flexibility and solubility, as well as lower surface tension. Correlation analysis demonstrates that the structural changes of 100SPI enhance the effective binding between SPI and 2-acetylfuran, thereby improving the adsorption capacity of SPI. This work offers a theoretical foundation for flavor selection in SPI-based food production by shedding light on the mechanism through which conformational changes in flash-evaporation-treated SPI impact its capacity for flavor adsorption.

Nobiletin (NOB), a lipid-soluble polymethoxyflavone with potent antioxidant, antimicrobial, and anti-inflammatory properties, suffers from poor stability and pH sensitivity, limiting its bioavailability. In this study, Pickering high internal phase emulsions (HIPEs) stabilized by soy protein isolate (SPI) and κ-carrageenan (KC) were developed to encapsulate and protect NOB. The emulsions, containing a 75 % medium-chain triglyceride (MCT) volume fraction, were optimized by investigating the effects of pH and KC concentration on the key properties such as the creaming index, particle size, zeta potential, microstructure, and rheology. Results showed that under optimal conditions (pH 7 and 1.0 % KC), the SPI/KC HIPEs exhibited improved physicochemical properties. Furthermore, encapsulation of NOB in HIPEs significantly improved its stability against UV exposure, heat, and storage conditions. Additionally, simulated gastrointestinal digestion studies revealed that the SPI/KC HIPEs improved the digestion stability and bioaccessibility of NOB, with controlled release in the intestinal phase. Moreover, the SPI/KC HIPEs facilitated increased cellular uptake and bioavailability of NOB, with clathrin-mediated endocytosis and macropinocytosis as primary absorption pathways. The encapsulated NOB also showed enhanced inhibition of inflammatory markers, including NO, IL-6, and TNF-α. These findings suggested that SPI/KC HIPEs provided a promising delivery system for improving the bioavailability and bioactivity of hydrophobic compounds.
