In this study, chitosan (CS) and xanthan gum (XG) were used as the base materials to prepare edible films containing cornmint oil (CO). The physical properties and structural characteristics of the films were thoroughly analyzed, along with an investigation into their preservation effect on blueberries. Scanning electron microscopy (SEM) showed that cornmint oil was successfully integrated into the edible film; however, aggregation was observed at higher concentrations. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed successful incorporation of the components. Notably, the CXG-1.5 film exhibited excellent thermal stability, barrier properties, significant antibacterial and antioxidant activities, compared to other formulations. During a storage period of 8 d for blueberries, compared with the control group, the CXG-1.5 group reduced the decay rate by 44.02%, reduced the weight loss rate by 75.85%, and reduced the malondialdehyde increase by 44.39%. At the same time, it maintained a high hardness and minimized the loss of 48.8% of total soluble solids and 56.34% of anthocyanins. Consequently, this novel cornmint oil-containing edible film effectively prolongs the shelf life of blueberries. These results suggest that the edible film developed in this study holds substantial potential for application in post-harvest preservation of fruits and vegetables.

Lithium-rich manganese-based cathode materials have the advantages of high specific capacity and operating voltage, but they still pose some problems such as poor cycle performance and serious voltage fading. Here, xanthan gum (XG) with double-helix structure has been investigated as a novel aqueous binder to improve the electrochemical performance of Li[Li 0.2 Co 0.13 Ni 0.13 Mn 0.54 ]O 2 . When the mass proportion of XG is 5%, the prepared lithium-rich cathode shows the highest specific capacity and best cycle stability. After cycling, the discharge voltage of the lithium-rich cathode decreases by only 273 mV, indicating that XG can effectively inhibit the voltage fading of the lithium-rich material.

Silicon-based anodes, which are used in lithium-ion batteries (LIBs), have a higher energy density than graphite anodes, making them one of the most promising alternative materials. This study introduces a flexible polyacrylamide (PAM) water-based three-dimensional network binder (M a X b ) for stabilizing silicon-based anodes (silicon-carbon composite materials, Si/C), based on the double helix structure of xanthan gum (XG). The chemical bonds formed by the cross-linking of carboxyl groups in XG with amide groups in PAM, as well as the hydrogen bond interactions, enhance the adhesive strength between the materials. By constructing XG cross-linked binders with different rigid-to-flexible ratios, the electrochemical performance of silicon-based anodes is improved. Among these, the M6X1-5 binder demonstrates a high lithium-ion diffusion coefficient average 1.80 × 10 −9 cm 2 s −1 and favorable cycling performance after 100 cycles at 0.1 A g −1 , with a reversible capacity of 481 mAh g −1 and a capacity retention rate of 81 %. Furthermore, its cost-effectiveness and environmentally friendly characteristics make it a promising candidate for application in high-capacity LIBs.

Calcium chloride water-based drilling fluids are widely used because of their excellent inhibition performance, but rheological control remains a key constraint on their development. Xanthan gum (XG) is the rheological modifier of choice, yet its structural evolution and molecular mechanisms under high‑calcium alkaline hydrothermal conditions remain unexplored. Using inorganic bases as controls, this study investigated the effects of three alkanolamines on the rheological behavior and structural evolution of XG after hydrothermal aging in high-calcium brine. The results showed that the inorganic-base systems almost completely lost their rheological properties after aging, whereas the alkanolamine systems exhibited superior hydrothermal stability. Diethanolamine (DEA) performed the best, showing the highest low-shear viscosity, yield stress, and shear-thinning characteristics. Structural characterization revealed that the DEA system exhibited better preservation of β-glycosidic linkages, oxygen-containing environments, high-molecular-weight chains, and microscopic networks. Molecular dynamics simulations demonstrated that DEA formed a multipoint noncovalent interaction network with XG chain segments and maintained the local hydration environment, mitigating chain dehydration and local structural disturbance induced by high-temperature and high‑calcium conditions. This study elucidates the molecular mechanism by which alkanolamines, particularly DEA, enhance the hydrothermal stability of XG, providing a basis for the stabilization design of polysaccharide-based fluids under high-calcium alkaline hydrothermal conditions.

In this study, Pickering emulsion gels were prepared by the self-gel method based on kappa carrageenan (kC). The effects of particle stabilizers and polysaccharide concentrations on the microstructure, rheological characteristics, and texture of Pickering emulsion gels stabilized by xanthan gum/lysozyme nanoparticles (XG/Ly NPs) with kC were discussed. The viscoelasticity of Pickering emulsion gels increased significantly with the increase of kC and XG/Ly NPs. The results of temperature sweep showed that the gel formation mainly depended on the kC addition. The XG/Ly NPs addition could accelerate the formation of Pickering emulsion gels and increase its melting temperature (Tmelt), which is helpful to improve the thermal stability of emulsion gels. Cryo-scanning electron microscope (Cryo-SEM) images revealed that Pickering emulsion gel has a porous network structure, and the oil droplets were well wrapped in the pores. The hardness increased significantly with the increase of XG/Ly NPs and kC. In particular, the Pickering emulsion gel hardness was up to 2.9 Newton (N) when the concentration of kC and XG/Ly NPs were 2%. The results showed that self-gelling polysaccharides, such as kC, could construct and regulate the structure and characteristics of Pickering emulsion gel. This study provides theoretical support for potential new applications of emulsion gels as functional colloids and delivery systems in the food industry.Keywords:Pickering emulsion gels;kappa carrageenan;rheological properties;microstructure

New Pickering emulsion stabilizer LS/XG-NPs (Lotus root starch/xanthan gum nanoparticles) was prepared via autoclaving-cooling method followed by combination with XG. The LS/XG-NPs showed uniform and stable particles with particle size <500 nm, PDI <30, and zeta potential 30–40. The autoclaving-cooling treatment completely changed the crystalline form (from A-type to B-type) and structure of starch; hydrogen bonding and electrostatic interactions were proved to be existed between starch and XG in LS/XG-NPs. The addition of XG increased the contact angle of LS/XG-NPs from 58.79° to 85.42°. In the prepared Pickering emulsion, the LS/XG-NPs adsorbed well on the oil droplets surface, forming a three-dimensional gel network with evenly distributed oil droplets. The Pickering emulsion prepared with LS/XG-NPs showed excellent storage stability and auto-oxidation resistance; the EPA + DHA content in the emulsion remained at 92.46 % after 5 d of storage. The results of this study suggest that LS/XG-NPs have the potential to be food-grade Pickering emulsifiers that not only stabilize emulsions but also prevent emulsion oils from oxidizing.

In this study, nanoparticles (NPs) prepared with xanthan gum and lysozyme were established as a powerful delivery system for two Se-containing peptides: TSeMMM (STP) and SeMDPGQQ (SHP). NPs-STP and NPs-SHP had relatively small particle sizes (145 nm and 148 nm) and negative zeta potentials (−47 mV and −49 mV). The encapsulation efficiency of NPs-STP and NPs-SHP was determined to be 34.35% and 41.35%, respectively. The stability and antioxidant activity of Se-containing peptides were greatly enhanced due to encapsulation. NPs-STP and NPs-SHP exhibited controlled release of Se-containing peptides under in vitro gastrointestinal conditions. NPs-STP and NPs-SHP showed low toxicity and entered Caco-2 cells through clathrin-mediated endocytosis, contributing to a significant increase in the apparent permeability coefficient of STP (2.19 × 10 −6 cm/s) and SHP (2.21 × 10 −6 cm/s). Thus, NPs-STP and NPs-SHP are considered promising delivery systems for Se-containing peptides and have good potential applications in the food and pharmaceutical industries.

Bacterial infections are the major challenges of wound treatment in current clinical applications. In this study, Three-dimensional (3D) antibacterial wound dressing has been fabricated via introducing N-halamine/TiO 2 to gelatin methacrylate and xanthan gum. The prepared 3D printed dressings showed ideal swelling ratio and excellent water uptake efficiency. TiO 2 nanoparticles were introduced by in-situ to improve the ultraviolet stability of N-halamines. The 3D printed GX2-TiO 2 -PSPH-Cl prepared dressings containing titanium dioxide retained 0.19% active chlorine after ultraviolet irradiation for 20 min, which was much higher than that of N-halamine dressings without the addition of TiO 2 . The 3D printed dressings showed good antibacterial activity, and 100% of Escherichia coli O157:H7 and Staphylococcus aureus were inactivated after 60 min of contact. Furthermore, the biofilm test indicated that the 3D antibacterial dressings were able to inhibit the formation of bacterial biofilm. The 3D printed dressings possess outstanding biocompatibility. Moreover, in vivo data demonstrated that the 3D printed dressings could significantly accelerate wound healing in a mouse model, indicating that the developed 3D printed dressings are ideal candidates for wound treatment.

High friction of damaged cartilage requires long-acting lubricated additive, which can also effectively scavenge reactive oxidative species (ROS) produced by mechanically stimulated chondrocytes . In this study, xanthan gum (XG) was grafted by poly (sulfobetaine methacrylate) (PSBMA) (the [XG]/[SBMA] molar ratio is 1:5 or 1:10), forming nanoparticles and then conjugated with collagen II-binding peptide, finally obtaining CBPXGSB1/5 or CBPXGSB1/10. Therein, the CBPXGSB1/5 was chosen as optimal lubricated additive. The results show that hydrated effect of PSBMA side chains endows CBPXGSB1/5 with favorable lubrication property (COF is 0.063). Furthermore, the CBPXGSB1/5 combining lubrication property and specific binding capability together may achieve the long-acting lubrication for injured cartilage in medical field. The CBPXGSB1/5 also possesses antioxidation verified by DPPH assay and exhibits synergistically enhanced ROS ( OH, O 2 − and H 2 O 2 ) scavenging. Besides, cytotoxicity experiment demonstrates that CBPXGSB1/5 has good biocompatibility. Therefore, multifunctional CBPXGSB1/5 developed here may have promising application potential in osteoarthritis treatment.

This study evaluated the gel and microstructure properties of scallop ( Patinopecten yessoensis ) male gonads hydrolysates (SMGHs) combined with xanthan gum (XG). SMGHs/XG hydrogel matrix properties and structures were elucidated via different analysis tools such as rheometry, LF-NMR, FTIR, AFM, and Cryo-SEM. The addition of XG significantly improved the rheological properties of SMGHs, as indicated by 3.1-fold G′ and 1.3-fold melting temperature with increasing the XG dose to 5.6 mg/ml. The corresponding decrease in the T 23 relaxation time from 450.3 to 365.6 ms also signified the strong binding between SMGHs and XG. SMGHs/XG also had a higher proton density ( T 1 and T 2 weighted images) due to the higher bound and free water content of the hybrid gel systems, respectively. Additionally, the blueshift in the amide I and II bands in SMGHs/XG further indicated stronger electrostatic interactions between SMGHs and XG. Such scenarios resulted in a well-distributed and compact network with a rougher surface of SMGHs/XG in comparison to pure SMGHs and XG, as assessed by AFM and SEM. These results suggest that SMGHs/XG gel could be a potential hybrid gel applied in the food industry. Practical Application Scallop ( Patinopecten yessoensis ) male gonads are edible, but are usually discarded during processing of scallop adductor. Because of its rich nutrition and gelation properties, scallop male gonads have a potential role in developing marine source-protein as a functional food base. The SMGHs/XG binary gel would be potentially applied in delivery system in food and biological fields. Further study is undergoing to apply SMGHs/XG binary gel to embed bioactive compounds, such as curcumin and β-carotene.

As dye adsorbents with great potential, polysaccharide-based hydrogels are significantly hampered in practical application owing to intricate preparation methods, low absorption, and bad degradability. Salecan is a water-soluble extracellular polysaccharide with excellent physicochemical and biological properties. Here, salecan and xanthan gum were first used as a dual-precursors system, their mixed solution was crosslinked by Fe 3+ to assemble a photo-degradable ionic gel for malachite green (MG) adsorption. Photo-degradation was done using visible light under very mild conditions, which gave rise to gel network dissolution and homogeneous solution formation. Extensive dynamic coordinate interactions between Fe 3+ and polysaccharides maintained gel matrix stability and were systematically investigated. The control of water uptake, micro-structure, and rheology can be facilely implemented by tuning salecan/xanthan gum ratios. Furthermore, various parameters such as polysaccharide ratios, pHs, MG concentrations, and contact time affecting adsorption were optimized using batch experiments. Adsorption process accurately adhered to pseudo-second-order kinetic and Langmuir isotherm model, with the maximum adsorption capacity of 463.0 mg/g. Such mechanism implied monolayer chemisorptive characteristics. The gel exhibited satisfactory reusability and was recycled five times without apparent decrease in adsorption capacity. From these results, the photo-degradable Fe 3+ -induced salecan/xanthan gum ionic gel is an alternative and sustainable absorbent for MG removal.

To investigate the effects ultrasound (20 kHz, 150–600 W) on physicochemical properties of emulsion stabilized by myofibrillar protein (MP) and xanthan gum (XG), the emulsions were characterized by Fourier transform infrared (FT-IR) spectroscopy, ζ-potential, particle size, rheology , surface tension, and confocal laser scanning microscopy (CLSM). FT-IR spectra confirmed the complexation of MP and XG, and ultrasound did not change the functional groups in the complexes. The emulsion treated at 300 W showed the best stability, with the lowest particle size, the lowest surface tension (26.7 mNm −1 ) and the largest ζ-potential absolute value (25.4 mV), that were confirmed in the CLSM photos. Ultrasound reduced the apparent viscosity of the MP-XG emulsions, and the changes of particle size were manifested in flow properties. Generally, ultrasound was successfully applied to improve the physical stability of MP-XG emulsion, which could be used as a novel delivery system for functional material.
