The effect of interaction between ovotransferrin fibrils (OVTFs) and citrus pectin (CP) on the properties of oleogel-based Pickering emulsions was innovatively explored. Firstly, the interaction between OVTFs and CP was investigated by constructing OVTF–CP complexes. OVTF–CP complexes with better stability were obtained when OVTFs to CP mass ratio of 3:1 at pH 5.0, which exhibited pearl chain-like structures by electrostatic attractions. Subsequently, to discuss the effect of interaction between OVTFs and CP on the properties of oleogel-based Pickering emulsions, oleogel-based OVTF-stabilized Pickering emulsion (OE) and oleogel-based OVTF–CP complex-stabilized Pickering emulsion (OCPE) were developed. The interaction between OVTFs and CP endowed OCPE with better stability, smaller droplet size, more prominent gel-like structure, higher viscosity and superior texture properties compared with OE. To construct an efficient delivery system for nutraceuticals, OE and OCPE were used to load curcumin . Compared with curcumin-loaded OE, curcumin-loaded OCPE had excellent protection for curcumin, higher rate of lipolysis and bioaccessibility of curcumin. Our work demonstrates that the interaction between OVTFs and CP can regulate the properties of oleogel-based Pickering emulsions, which will provide new insights into the formation and application of protein fibril–polysaccharide complexes. This may contribute to the precise development of Pickering emulsions with protein fibril–polysaccharide structures and ideal properties.

This study objected to widen the knowledge and applications of bigels by constructing food bigels for 3D printing. A serious of bigels were developed by incorporating a candelilla wax-based oleogel into a gelatin hydrogel at different oleogel/hydrogel ratios of 3:7, 5:5, and 7:3 under the presence of different emulsifiers (PGPR, monoglycerides and lecithin). And the influence of different oleogel/hydrogel ratios and emulsifiers on the physical properties and 3D printability of resulting bigels were studied. Bigels containing monoglycerides or lecithin could form homogenous, stable gel system with bicontinuous emulsion structure . Microstructure analysis found that PGPR could disturbed the crystalline process of candelilla wax resulting in weak mechanical strength of resulting oleogel and phase separation of bigels. These bigels exhibited shear-thinning behavior and improved mechanical properties (apparent viscosity, storage modulus, hardness, etc.) compared to pure oleogel and pure hydrogel. Bigels containing monoglyceride with oleogel/hydrogel ratio of 7:3 exhibited suitable mechanical properties for 3D printing. The results from this study indicated that 3D printable bigels could be obtained by combining candelilla wax (organogelators) with gelatin (hydrogelator), and the physical, printing properties of these bigels could be tailored by adjusting oleogel/hydrogel ratios and using different emulsifiers.

Biodegradable conductive composites are key materials or components for printable transient electronics that can be fabricated in a low-cost and high-efficiency manner, thereby boosting their wide applications in biomedical engineering, hardware security, and environmental-friendly electronics. Continuous efforts in this area still lie in the development of strategies for highly conductive, safe, and reliable biodegradable conductive composite materials and devices. This paper introduces molybdenum/wax composites for multimodally printable transient electronics in which multiple transience modes including dissolution-induced degradation and thermally triggered degradation are available. Systematic experiments demonstrate several advantages and unique properties of this material system, including solvent-free fabrication, self-sintering behavior, and long-term and high conductivity via accelerable self-sintering treatment and rehealing capabilities. Notably, the immersion of molybdenum/wax composites in phosphate buffer solution can provide both positive effects (accelerated self-sintering-dominated) and negative effects (degradation-dominated) on their electrical conductivities. Mechanism analyses reveal the basis for balancing the degradation and accelerated self-sintering processes. The presented demonstrations foreshadow opportunities of the developed molybdenum/wax composites in rehealable electronics, on-demand smart transient electronics with multiple transience modes, and many other related unusual applications.

The present study aimed to enhance the bioaccessibility of hydrophobic astaxanthin (AST) by developing food-grade emulsion systems. Ovalbumin (OVA) fibrils and candelilla wax-based oleogels were prepared for the next fabrication of AST-loaded oleogel-based Pickering emulsions. The food-grade oleogel was obtained by mixing 0.7% (w/w) candelilla wax and soybean oil . The nano-scale OVA fibrils were observed by transmission electron microscope. SDS-PAGE analysis of OVA fibrils displayed the appearance of peptides with molecular weight around 10 kDa. Contact angle measurement indicated that excellent amphiphilicity endowed OVA fibrils with satisfactory Pickering emulsifier performance. The obtained oleogel-based Pickering emulsions displayed ultrastability during 90-day storage and outstanding freeze-thaw stability. Furthermore, the superiority of AST-loaded oleogel-based Pickering emulsion was further reflected in the apparently ameliorative lipolysis extent and AST bioaccessibility compared with oleogel. This work would facilitate the utilization of OVA and the development of oleogel-based Pickering emulsions with desirable nutraceutical bioaccessibility.

This work prepared food-grade oleogel-based Pickering emulsion stabilized by ovotransferrin (OVT)–carboxymethyl chitosan (CMCS) nanoparticles (OPEOC). The analysis of emulsified phase volumes and stability index exhibited that OPEOC with different volumes of oil fraction remained stable for 2 months of storage. The prepared Pickering emulsions were used as delivery systems for curcumin. In vitro digestive studies showed that OPEOC significantly improved the degree of lipolysis and the bioaccessibility of curcumin compared to the sunflower seed oil-based oleogel. The oleogel-based Pickering emulsions fabricated in the present study had noticeable storage stability, high loading and improved bioaccessibility of nutraceuticals, which might provide new insights into the development of novel food-grade Pickering emulsions with excellent properties.

The objective of this work was to develop nanostructured lipid carriers (NLCs) with preservation effect by using pea protein isolate (PPI) nanoparticles as emulsifiers, candelilla wax (CW) as organo-gelator and d -limonene (DL) as antifungal agent. The optimal formulation parameters of NLCs were firstly determined based on results of particle size, poly-dispersity index and zeta potential, and then NLCs prepared by optimal formulation were further characterized. The results showed that DL was successfully encapsulated inside NLCs. Moreover, the encapsulation of amorphous DL led to more disordered crystalline state of NLCs. In addition, in comparing the properties of NLCs and nanoemulsions (NEs) without CW, it was found that the addition of CW seemed to have several beneficial effects on NLCs: 1) NLC droplets were well dispersed, whereas NE droplets exhibited coalescence and flocculation; 2) compared with NEs, NLCs displayed excellent storage stability and inhibition ability of DL release. Furthermore, antifungal activity of NLCs was observed by in vitro and in vivo study. The acquired information in current research can provide novel insight into development of stable and antifungal nanocarriers that own a promising application in tomato preservation.

Bigels are system with great potential in 3D printing and bioactive compound delivery. In this study, 3D printed bigels based on candelilla wax oleogel and gelatin hydrogel were developed as delivery system for hydrophilic and lipophilic bioactives (namely, quercetin and catechin). Bigels with monoglyceride or lecithin formed stable gel system with 3D printing ability. Microstructural study found that changing of oleogel/hydrogel ratios (3:7, 5:5, and 7:3) under the presence of different emulsifiers (monoglyceride and lecithin) led to structural transformation of bigels from oleogel-in-hydrogel structure to hydrogel-in-oleogel or bicontinuous status. Low frequency-NMR analysis indicated that the signals of typical T 2 relaxation peak were changed accordingly with variations of oleogel/hydrogel ratio and using of different emulsifiers. XRD patterns of bigels revealed their crystalline peaks grew with increase of oleogel content. In vitro digestion study found that both oleogel/hydrogel ratio and emulsifiers used exhibited large influence on the lipolysis extent, release rate of quercetin and catechin from bigels. The highest release rate for catechin (53.37%) and quercetin (11.08%) were observed in bigels containing monoglyceride with 70% oleogel and lecithin with 30% oleogel after simulated digestion, respectively. This study provided valuable guidance for developing bigels as 3D printed food with potential in co-delivery of hydrophilic and lipophilic bioactives by adjusting oleogel/hydrogel ratios and emulsifiers used.

The process of spraying water and flavorings on dry tobacco is an important factor in the industrial environment and product quality. Tobacco as a complex porous fiber material, the interfacial transfer process of water is complex. In this study, machine learning and image recognition techniques were utilized to quickly obtain the structural parameters of the tobacco surface and construct a cellular structure model of the tobacco surface. In situ observation of the droplet impact spreading process was carried out using a high-speed camera to explore the droplet dissipation dynamics on different surfaces. And the competing processes of droplet wetting and evaporation under the influence of surface microstructure were determined by combining experimental studies and finite element simulation calculations. Based on the characteristics of tobacco pore size distribution, the infiltration under gas–liquid two-phase action was transformed into single-phase flow transfer under capillary force, and the continuous droplet infiltration process was simulated. A parallel artificial membrane permeability measurement method of bionic tobacco waxy layer was constructed for the screening of spray dosing copenetrant. This study brings new insights into the wetting of porous fibrous materials and is important for exploring the wetting process and additive development process influenced by the microstructure.

This project aimed to explore the influence of the interaction between ovotransferrin fibrils (OTF) and gum arabic (GA) on the formation mechanism, physicochemical properties, and curcumin delivery of the oleogel-in-water Pickering emulsion. Cryo-scanning electron microscopy results showed that OTF—GA complexes effectively adsorbed on the oil–water interface, generating spatial hindrance to inhibit droplet coalescence. The texture analysis also proved that OTF—GA complexes endowed oleogel-in-water Pickering emulsion with preferable springiness (0.49 ± 0.03 mm), chewiness (0.43 ± 0.07 mJ), and adhesion (0.31 ± 0.01 mJ). By exploring the coalescence stability, droplet size, and rheological properties of OTF—GA complexes–stabilized oleogel-in-water Pickering emulsion (OGPE), the higher coagulation stability, larger average droplet size (46.22 ± 0.08 μm), and stronger gel strength were observed. The microrheological results also exhibited stronger attraction between the OGPE droplets, a more pronounced solid-like structure, and a slower speed of movement than OTF-stabilized oleogel-in-water Pickering emulsion (OPE). Meanwhile, OGPE significantly enhanced the extent of lipolysis, stability, and bioaccessibility of curcumin, suggesting that it possessed superior performance as a delivery system for bioactive substances. This project provided adequate theoretical references for protein–polysaccharide complexes–stabilized oleogel-in-water Pickering emulsion, and contributed to expanding the application of oleogel-in-water Pickering emulsion in the food industry.

Microbial contamination is the leading cause of food spoilage and food-borne disease. Here, we developed a multifunctional surface based on polylactic acid (PLA) bioplastic with antifouling and antibacterial properties via a facile dual-coating approach. The surface was designed with hierarchical micro/nano-scale roughness and low surface energy. Bactericidal agent polyhexamethylene guanidine hydrochloride (PHMG) was incorporated to endow the film with bactericidal activity. The film had good superhydrophobic, antifouling and antibacterial performance, with a water contact angle of 154.3°, antibacterial efficiency against E. coli and S. aureus of 99.9 % and 99.6 %, respectively, and biofilm inhibition against E. coli and S. aureus of 63.5 % and 68.9 %, respectively. Synergistic effects of antibacterial adhesion and contact killing of bacteria contributed to the significant antibacterial performance of the film. The biobased biodegradable film was highly effective in preventing microbial growth when applied as antibacterial food packaging for poultry product, extending the shelf life of fresh chicken breast up to eight days.

Hydraulic fracturing produces complex organic wastewater, known as fracturing flowback fluid (FFF), which contains refractory pollutants and poses risks of secondary contamination, thereby challenging conventional treatment methods. This study developed an environmentally sustainable strategy using a microbial flocculant (MBF) synthesized from Bacillus paramycoides YQ1—a strain isolated from FFF—in combination with candelilla wax- modified fly ash cenospheres (CWFACs). Through process optimization, the MBF yield was increased from 4.38 to 5.78 g·L⁻¹ , and its flocculation efficiency improved from 60.06 % to 87.84 %. Under optimal conditions, MBF alone achieved removal rates of 86.67 % for chroma, 81.98 % for suspended solids (SS) removal, and 65.13 % for oil, along with effective degradation of polycyclic aromatic hydrocarbons (PAHs). The integrated MBF-CWFACs system demonstrated enhanced performance, attaining 88.50 % chroma removal, 96.29 % SS removal, and 95.30 % oil removal. Mechanistic analysis revealed synergistic effects between bioflocculation and adsorption processes. This integrated approach offers a sustainable solution for FFF treatment, addressing both process efficiency and environmental safety concerns, providing insights for developing eco-friendly wastewater treatment technologies in the petroleum industry.
