The effects of xanthan gum (XG) on the gelation, swallowing properties and mechanisms of silver carp (SC) surimi and grass carp (GC) surimi were investigated. The results showed that the composite modulus, hardness and chewiness of SC and GC samples decreased by 8.8%-50.7% as XG concentration increased from 0% to 4%. The SC and GC samples with 1% or 2% XG could be classified as level 6 diets according to the International Dysphagia Diet Standardization Initiative framework. Additionally, SC and GC samples exhibited a 6.4%-30.8% decrease in cooking loss and a 0.8%-3.9% increase in water holding capacity with the addition of XG. Moreover, the introduction of XG led to decreases in the hydrophobic interactions and disulfide bonds whithin SC and GC composite systems, resulting in softer and looser structures. Furthermore, the results of molecular dynamics simulation demonstrated myosin-XG interactions are driven primarily by significant electrostatic forces. These results highlighted the potential of XG as an effective textural modifier for producing freshwater fish soft surimi gels.

The interaction mechanism between surfactants and polymers has important guiding significance in the field of high-performance fluid design. However, research on the interactions between biological surfactants and microbial polysaccharides remains limited. In this paper, the effect of xanthan gum on the interfacial properties of an acidic sophorolipid solution, such as surface tension, viscosity, rheology and foam properties, was systematically studied by means of experimental and theoretical methods. The results showed that the addition of 0.1 wt% xanthan gum had little effect on the critical micelle concentration of acidic sophorolipid, and increased the contact angles of the aqueous solution with PTFE and PP. At the same time, the interaction between acidic sophorolipid and xanthan gum reduced the bulk viscosity of the xanthan gum solution. Furthermore, the shear-thinning characteristics of the mixed system did not change, but the yield value gradually decreased with increasing acidic sophorolipid concentration. Significantly, the addition of xanthan gum slightly reduced the foaming property of acidic sophorolipid but significantly improved the stability of the foam. Foam counting and image analysis showed that xanthan gum not only made the foam small and evenly distributed, but also inhibited the aggregation of foam effectively as acidic sophorolipid concentration increased. Finally, in order to reveal the molecular mechanism underlying the interaction between xanthan gum and acidic sophorolipid, DFT calculations were used to simulate their interaction. The results indicated that robust hydrogen bonding interactions involving carboxyl and hydroxyl groups exist between acidic sophorolipids and xanthan gum, thereby contributing to the enhancement of foam stability. These findings would provide useful references for biosurfactant applications in complicated formulations across diverse fields.

The poor gel property of plant proteins and phase separation restrict plant-based yogurt products. In this study, anionic colloids were evaluated for walnut yogurt production, and sodium alginate (SA) or xanthan gum (XG) greatly improved the overall quality of walnut yogurt. The incorporation of SA or XG at low concentrations (0.5–0.6%) effectively promoted fermentation and significantly increased the total phenolic content in walnut yogurt 1.47 and 1.23 times, respectively, compared to the control group. Concurrently, the water-holding capacity increased approximately 3 times. Both gums also improved the textural and rheological properties of the yogurt, notably increasing the hardness and chewiness. Sensory analysis confirmed that yogurts containing 0.5–0.6% SA or XG received higher overall sensory scores. Notably, SA incorporation could promote the formation of a dense network structure in walnut yogurt, while the XG incorporation could improve for the fermentation process of the yogurts.

Currently commercial glutaraldehyde (GA)-crosslinked bioprosthetic valve leaflets (BVLs) suffer from thromboembolic complications, calcification, and limited durability, which are the major stumbling block to wider clinical application of BVLs. Thus, developing new-style BVLs will be an urgent need to enhance the durability of BVLs and alleviate thromboembolic complications. In this study, a quick and effective collaborative strategy of the double crosslinking agents (oxidized polysaccharide and natural active crosslinking agent) was reported to realize enhanced mechanical, and structural stability, excellent hemocompatibility and anti-calcification properties of BVLs. Dialdehyde xanthan gum (AXG) exhibiting excellent stability to heat, acid-base, salt, and enzymatic hydrolysis was first introduced to crosslink decellularized porcine pericardium (D-PP) and then curcumin with good properties of anti-inflammatory, anti-coagulation, anti-liver fibrosis, and anti-atherosclerosis was used to synergistically crosslink and multi-functionalize D-PP to obtain AXG + Cur-PP. A comprehensive evaluation of structural characterization, hemocompatibility, endothelialization potential, mechanical properties and component stability showed that AXG + Cur-PP exhibited better anti-thrombotic properties and endothelialization potential, milder immune responses, excellent anti-calcification properties and enhanced mechanical properties compared with GA-crosslinked PP . Overall, this cooperative crosslinking strategy provides a novel solution to achieve BVLs with enhanced mechanical properties and excellent anti-coagulation, anti-inflammatory, anti-calcification, and the ability to promote endothelial cell proliferation .

Strong and ductile sodium alginate (SA) reinforced polyacrylamide (PAM)/xanthan gum (XG) double network ionic hydrogels were constructed for stress sensing and self-powered wearable device applications. In the designed network of PXS-M n+ /LiCl (short for PAM/XG/SA-M n+ /LiCl, where M n+ stands for Fe 3+ , Cu 2+ or Zn 2+ ), PAM acts as a flexible hydrophilic skeleton, and XG functions as a ductile second network. The macromolecule SA interacts with metal ion M n+ to form a unique complex structure, significantly improving the mechanical strength of the hydrogel. The addition of inorganic salt LiCl endows the hydrogel with high electrical conductivity , and meanwhile reduces the freezing point and prevents water loss of the hydrogel. PXS-M n+ /LiCl exhibits excellent mechanical properties and ultra-high ductility (a fracture tensile strength up to 0.65 MPa and a fracture strain up to 1800%), and high stress-sensing performance (a high GF up to 4.56 and pressure sensitivity of 0.122). Moreover, a self-powered device with a dual-power-supply mode, i.e., PXS-M n+ /LiCl-based primary battery and TENG, and a capacitor as the energy storage component was constructed, which shows promising prospects for self-powered wearable electronics.

Xanthan gum (XG) was added to egg-white-gel-derived peptides to create complexes and stabilise nanoemulsion under high-pressure homogenisation. This procedure was performed to investigate the stabilisation of nanoemulsions by small-molecule peptides under alkaline conditions (pH 11.0). The emulsion stability, including ionic, temperature and storage stability, and lipid oxidation were explored. The inclusion of XG altered the spatial structure of the peptides, which created cross-linked entangled aggregates. Furthermore, the protein peptides forming complexes with XG following sonication and heat treatment were more stable. They exhibited higher absolute ζ -potential values, surface hydrophobicity, and lower interfacial tension. The emulsion stabilised by 2.0 mg/mL complexes at a pH of 11.0 revealed that the addition of XG enhanced the homogeneity of the nanoemulsion droplets, presenting a single high particle size peaks and absolute ζ -potential values. The surface-absorbed protein content and the concentrations of the emulsions stabilised by sonication and the heat-treated peptides and XG complexes were higher. Moreover, the fluorescence microscope observed a higher surface coverage thickness of the emulsion droplets, effectively preventing oil oxidation. The emulsion environmental stability measurements found that the prepared emulsions were sensitive to salt ions and stable to temperature. Together with heat-treated peptides and XG complexes, sonication-stabilised emulsions exhibited better stability during storage. This study advances the possibility of stabilising the nanoemulsions of small-molecule peptides under alkaline conditions.

Although it has been proven that the addition of shear-thinning polymers can lead to an improvement in the sweeping efficiency of the remedial agent in heterogeneous aquifers, the related mechanisms require further investigation. This study revealed the mechanisms associated with the improvement of fluid sweeping uniformity. Under the assumption of no transverse flow existed between layers, the variation patterns of the fluid sweeping uniformity in strip layered heterogeneous media ( R P / R K ) with the change of the fluid hydraulic conductivity were investigated. The outcomes showed that, for the hydraulic conductivity dominated fluid sweeping uniformity control, the performance was satisfactory only when the ratio of the hydraulic conductivities of viscous fluid in porous media (PM) layers ( K 1P / K 2P ) is less than 2.5 times that of pure oxidant solution ( K 1K / K 2K ), and PM combinations with higher permeability contrast usually present a wider applicability and better performance. In addition, transverse fluid movement was more likely to occur in layers with low permeability contrasts (2.3–5) than in those with relatively higher permeability contrasts (> 11). The observed transverse pressure difference directly confirmed the hypothesis of the dynamics of the cross-flow mechanism that existed during viscous fluid flow, and the relationships between the fluid fronts and the pressure head difference at each point (Px) were proposed. Our study exemplifies an effective strategy for determining the most economically effective co-injection concentration of xanthan to achieve highly efficient delivery of remedial agents.

Biopolymers are increasingly being employed to reduce engineered barrier permeability and to control the migration of contaminants in soils or groundwater. This study evaluated the effects of sol-gel conversion in pore fluid on the gas permeability of compacted biopolymer-amended clayey soil. The sol-gel conversion was implemented using divalent calcium (Ca 2+ ) and trivalent chromium (Cr 3+ ) ions as bridging cations and xanthan gum (XG) as the source material of gel matrix. The chemical features and morphology of XG gels were characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, zeta potential, and particle size measurements. The strength and viscosity of XG gels were assessed. The results showed that the strength of XG gels initially increased and then decreased as concentration rose from 10 to 200 mM. With Ca 2+ and Cr 3+ concentrations of 50 mM and 10 mM, respectively, the viscosity of the 0.5 wt.% XG gel increased to 35 Pa s and 87 Pa s, which are approximately 2 and 5 times larger than that of the 0.5 wt.% XG solution (18 Pa s). Additionally, the gas permeability tests were conducted on the compacted XG-amended soils immersed in Ca 2+ /Cr 3+ solutions and cured under standard condition. The gas permeability of the XG-amended soil specimen immersed in the 10 mM Cr 3+ solution was measured to be 1.0 × 10 -15 m 2 , which is approximately one-quarter of that of the specimen (4.5 × 10 -15 m 2 ) immersed in deionized water and one-half of that of the specimen immersed in the 10 mM Ca 2+ solution (2.0 × 10 -15 m 2 ), highlighting the role of sol-gel conversion in improving gas barrier performance.

To address the limitations of Antarctic krill oil (AKO) such as easy oxidation , unacceptable fishy flavor and low bioaccessibility of astaxanthin in it, a multiple-effect delivery vehicle for AKO is needed. In this study, whey protein isolate (WPI) and xanthan gum (XG) were utilized to construct AKO into oleogels by generating foam-templates. The effects of the concentration of XG on the properties of foam, cryogel and the corresponding oleogels were investigated, and the formation mechanism of oleogel was discussed from the perspective of the correlation between foam–cryogel–oleogel. The results demonstrated that with the increase of the concentration of XG, the foam stability was improved, the cryogel after freeze drying had a more uniform network structure and superior oil absorption ability, and the corresponding oleogel had excellent oil holding ability after oil absorption. The AKO oleogels showed superior oxidative stability compared with AKO. The in vitro digestion experiments demonstrated that the bioaccessibility of the astaxanthin in this oleogel was also considerably higher than that in AKO. In addition, this oleogel had masking effect on the odor-presenting substances in AKO, while retaining other flavors of AKO. The foam-templated oleogel can be considered as a multiple-effect vehicle for AKO to facilitate its application in food products. This study provides theoretical basis and data support for the development and utilization of novel vehicle for AKO, broadening the application of AKO in the field of food science.

The clinical treatment of enterocutaneous fistula is challenging and causes significant patient discomfort. Fibrin gel can be used to seal tubular enterocutaneous fistulas, but it has low strength and poor digestion resistance. Based on in situ bioprinting and the anti-digestive properties of xanthan gum (XG), we used carboxymethyl chitosan (CMC) and xanthan gum modified by grafted glycidyl methacrylate (GMA) and aldehyde (GCX) as the ink to print a double network hydrogel that exhibited high strength and an excellent anti-digestive performance. In addition, in vitro studies confirmed the biocompatibility, degradability, and self-healing of hydrogels. In our rabbit tubular enterocutaneous fistula model, the in situ printed hydrogel resisted corrosion due to the intestinal fluid and acted as a scaffold for intestinal mucosal cells to proliferate on its surface. To summarize, in situ bioprinting GCX/CMC double network hydrogel can effectively block tubular enterocutaneous fistulas and provide a stable scaffold for intestinal mucosal regeneration.

Hydrogels with thixotropic and pH-sensitive properties exhibit injectablity and response to external stimulation. Thixotropic and pH-responsive hydrogels were fabricated from xanthan gum (XG) and a hyperbranched β -D-glucan (TM3a) crosslinked with sodium trimetaphosphate (STMP) for injectable and release-controlled application. Thixotropy and creep-recovery tests were carried out to determine injectable and viscoelastic properties of the XG-TM3a-STMP hydrogels. Introduction of TM3a and formation of chemically crosslinking structures resulted in higher yield stress (43.6–168.9 Pa) and elastic modulus (146.9–1245.7 Pa), lower retardation time (32.6–44.4 s), and higher recovery percentage (49.5–66.7%) for XG-TM3a-STMP compared to XG-STMP and XG-TM3a-water. FTIR spectra and SEM observation demonstrated that TM3a disassembled XG aggregates by partially breaking hydrogen bonds, resulting in a relatively thin wall of the grids for XG-TM3a-STMP. The XG-TM3a-STMP hydrogels exhibited pH dependant swelling property and controlled release behavior. The hybrid hydrogels have potential applications in 3D printing or injectable tissue engineering and drug release fields.

In this work, xanthan gum (XG) was exploited as a novel dolomite depressant in the flotation separation of apatite from dolomite in sodium oleate system. The flotation performances and adsorption mechanism of XG towards apatite and dolomite were studied through flotation tests, adsorption capacity measurements, micro-heat tests, atoms density calculations and surface characterizations. Flotation results revealed that XG exhibited strong depression effect on dolomite but barely influenced the flotation of apatite. The results of zeta potential, infrared spectroscopy analysis, adsorption capacity measurements and micro-heat tests proved that XG trended to adsorb on dolomite other than apatite, which hindered the adsorption of NaOL on dolomite and rendered the surface hydrophilic. Atom density calculations indicated that the preferential adsorption of XG on dolomite was due to much more dense and active Ca sites on dolomite surface than that of apatite. XPS results suggested that XG was strongly adsorbed on dolomite surface by means of chelation between COOH or OH groups within XG and Ca sites on dolomite, while it was weakly adsorbed on apatite by hydrogen bonding between OH groups within XG and F atoms on apatite surface.
