The effect of corn fiber gum (CFG) on the aqueous solutions of a series of widely-used commercial polysaccharides has been studied by rheological techniques using a shear stress synergism index I S to evaluate its viscosifying action. While CFG solution exhibited Newtonian fluid behavior with a very low viscosity even at a high concentration, the aqueous mixtures of CFG and some non-gelling polysaccharides (hyaluronan, guar gum , carboxymethylcellulose, hydroxyethylcellulose, konjac glucomannan , pectin and chitosan) showed a pseudoplastic fluid behavior. Furthermore, the addition of CFG showed a remarkable viscosifying action for the aqueous solutions of these non-gelling polysaccharides likely due to their interaction by hydrogen bonding. However, the viscosity behavior of CFG with some gelling polysaccharides such as methylcellulose, gellan gum , carrageenan , xanthan, may be based on a different mechanism. A proper model of intermolecular interaction between CFG and these gelling and non-gelling polysaccharides has been discussed and proposed.

This study proposes a kill two birds with one stone strategy to improve the health and safety of pork with high internal phase Pickering emulsions (HIPPEs). HIPPEs improved the pseudoplasticity and viscosity (from 619.3 to 1712 Pa·s at 0.1 s −1 ) of the pork, favoring smooth extrusion and adhesion of the ink. Shear recovery of pork gel increased from 39.20 % to 77.78 % by addition of HIPPEs. HIPPEs enhanced the pork gel viscoelastic properties (K 4 = 341.29, K 5 = 453.11) and yield stress (268.55 Pa). HIPPEs-adjusted pork gel (HPG) has favorable 3D printing, pork aroma, safe swallowing (level 5 food), and high digestibility (80.40 %), demonstrating its potential as a dysphagia diet. HPG reduced the cooking loss of pork (from 30.8 % to 1.9 %), which is suitable for dysphagic patients with reduced salivation. HIPPEs adjusts the properties of pork gel by filling and winding gel networks. These results provide new ideas for the development of special formula foods.

Dual encapsulation of β-carotene (CAT) by β-cyclodextrin (CCLD) and chitosan (CS) are prepared via self-assembly process by special addition order and concentration. CCLD and CS alone could not effectively stabilize CAT, while CAT could be encapsulated in cavity of CCLD and the inclusion complex could be further strengthened by CS, due to hydrogen-bonding between CCLD and CS via groups including NH 2 and OH. The dispersion system based on dual encapsulation of CAT had outstanding shear-thinning behavior, proper pseudoplastic properties, satisfactory yield stress, excellent thermal stability and great thixotropy, illustrating high potential for 3D printing. 3D printing of CAT-encapsulated system with high-content CS on paper and bread proves its excellent extrudability and printability, with possible potential in nutrition personalization. The designed host encapsulation structure by CCLD and CS plays a guiding role in incorporating functional materials including bioactives, probiotics, enzymes, vitamins, etc., and provides a reference in innovative food technology.

The study describes the effects of xanthan gum (0.5–2.0%) on the in vitro digestibility and rheological and pasting properties of kudzu ( Pueraria lobata ) starch pastes. The flow behavior index ( n ) shows a decrease in trends (from 0.43 to 0.31) as the xanthan gum concentration increases, indicating pseudoplastic behavior. Dynamic viscoelasticity analysis indicate that the elastic ( G ′) and viscous ( G ″) moduli increase in the presence of xanthan gum, suggesting a strong interaction between xanthan gum and kudzu starch in the composite system. All concentrations of xanthan gum result in increased elasticity ( G ′ > G ″). Pasting properties reveal that the peak and final viscosity of the xanthan gum–kudzu starch dispersion decreases with the increasing concentration of xanthan gum, highlighting the importance of xanthan gum in controlling overall viscosity. The addition of xanthan gum also decreases the hydrolysis of kudzu starch during in vitro digestion.

In this study, a material of pseudoplastic fluid was obtained by dealing with the original material of Pixian Douban (PXDB). The multi-scale temperature and flow fields (MTFF) were established, and a PXDB product fermented in the MTFF (PFM) was obtained. Meanwhile, the material of pseudoplastic fluid and the original material was also fermented into PXDB products named MPTF and OMP, respectively, following the traditional process. The contents of major physicochemical indexes, organic acids and free amino acids in the PFM were higher than those in the MPTF and OMP. A total of 112, 102, 105 volatile compounds were detected in the PFM, MPTF and OMP. The PFM was rich in esters and alcohols while MPTF was abundant in aldehydes. The PFM possessed higher soy sauce-like, umami, sour taste and sour smell by quantitative descriptive analysis (QDA). The PFM was positively correlated with many indexes by partial least squares discriminant analysis (PLS-DA), such as all physicochemical properties, Asp, Glu, C3 and A8. These results indicated that the flavor of PFM was richest, which showed that a PXDB product with higher quality could be obtained in MTFF.

The molecular motion of starch at different glycerol concentrations (0, 20, 50, and 80 %) was investigated using Electron Paramagnetic Resonance (EPR) spectroscopy. Fourier-transform infrared (FTIR) spectroscopy and 1 H nuclear magnetic resonance ( 1 H NMR) spectroscopy confirmed that hydroxyl groups at the C2 and C3 positions of glucose units in corn starch (CS), waxy corn starch (WCS), and high amylose corn starch (HCS) were labeled with 4-amino-TEMPO. The crystallinities of CS, WCS, and HCS after spin-labeling decreased from 30.68 % to 3.21 %, 39.36 % to 1.65 %, and 28.54 % to 8.08 %, respectively. The pseudoplastic fluid properties of the spin-labeled starch remained shear-thin at different glycerol concentrations. EPR revealed the fast- and slow-motion components of the spin-labeled starch molecules dispersed in water. At a glycerol concentration of 20 %, the slow-motion component disappeared, indicating a faster rotational motion of the starch chain segments. As the glycerol concentration increased to 50 and 80 %, the rotational motion slowed because of high viscosity. In particular, the mobility of the spin-labeled WCS chains increased owing to easier access of glycerol and water to the branched structure. This study directly observed the dynamics of the molecular behavior of starch in glycerol-water systems.

Starch nanoparticles (SNPs) were prepared through acid hydrolysis of Canna edulis native starch and modified with octenyl succinic anhydride (OSA) to yield OS-starch and OS-SNPs. These modified particles were used to stabilize curcumin-loaded Pickering emulsions. Effects on gut microbiota during in vitro fecal fermentation were examined. The surface of OS-starch exhibits a porous structure, while OS-SNPs display layered grooves. OSA modification was confirmed by Fourier transform infrared spectroscopy (with peaks at 1728 cm −1 and 1573 cm −1 ) and proton nuclear magnetic resonance spectra (0.5–2 ppm). The degree of substitution for OS-starch and OS-SNPs is 0.0106 ± 0.0004 and 0.0079 ± 0.0003, respectively. Following modification, the crystallinity decreased from 35.69 ± 0.46 % (native starch) to 30.17 ± 0.70 % (OS-starch), SNPs decreased from 45.87 ± 0.89 % to 43.63 ± 0.64 % (OS-SNPs). Contact angles for OS-starch and OS-SNPs are 77.47 ± 1.78 and 55.57 ± 0.21, respectively. OS-SNPs exhibited superior emulsification properties compared to OS-starch, forming stable Pickering emulsions with pseudoplastic fluid behavior and enhanced curcumin storage protection over 14 days (60.88 ± 4.26 %) with controlled release. Stabilizing Pickering emulsions with OS-starch and OS-SNPs positively affected on gut microbiota and improved the intestinal environment, showing promise for their application in transportation systems and innovative prebiotic food formulations.

In this study, the blank hydrogels and the niosomal hydrogels loading coenzyme Q10 (CoQ10) were prepared by carbomer (CBM) and scleroglucan (SCL), and their physicochemical properties were characterized in terms of rheological and texture measurement, FTIR, SEM, DSC, and DLS. First, the blank hydrogels CBM-SCL-Gel were prepared. With the increase of SCL concentration, the viscosity and modulus increased, displaying better shear thinning behavior of pseudoplastic fluid. A dense network structure was formed in CBM-SCL-Gel, especially for CBM/SCL at 5/4 and 5/5, due to hydrogen bonding between CBM and SCL. The swelling behaviors of the composite gels conformed to pseudo-second-order kinetics, and CBM/SCL at 5/1 exhibited the highest swelling capability. The addition of SCL made the water absorption mechanism tend to a non-Fickian diffusion mode. Then, the niosomal hydrogel was prepared by the optimized gel formulation with the CoQ10-loaded niosome. It was found that the gel properties were insignificantly affected by the CoQ10 niosomes. The particle sizes of the niosomes in the gel were a little larger than that in aqueous suspension. After storage for 30 days, the CoQ10 retention rate in the niosomal gel remained at 92% (4°C, N-Gel), representing high stability of CoQ10.

Excessive ultraviolet (UV) exposure can lead to sunburn, characterized by skin barrier damage, inflammation, pain, and an increased risk of skin cancer. Recombinant collagens have gradually attracted attention due to their high purity, low immunogenicity, batch-to-batch consistency, and excellent solubility. Additionally, the type of dressing significantly affects wound repair. Gels are ideal for sunburn treatment because they maintain a moist environment, adhere firmly, and do not need to be removed. Herein, we have created bioactive triple-helical recombinant collagen (THRC) gels for improved healing of sunburned skin. The THRC gels remained stable after a three-month stability test, displaying a rheological behavior characteristic of non-Newtonian pseudoplastic fluids. In vivo skin irritation tests conducted on New Zealand rabbits demonstrated that THRC gels were safe for use. A sunburned mice model was established to study the biological effects of THRC gels. Non-invasive combo evaluations indicated that THRC gels exhibited an exceptional capability of recovering dermis density, erythema index (EI), hydration, and transepidermal water loss (TEWL) of sunburned skin to a healthy state. Histological observations revealed that THRC gels significantly enhanced the repair of damaged skin by accelerating the recovery process, promoting collagen deposition and regeneration. Molecular biological characterizations further demonstrated their remarkable antioxidant properties, including the inhibition of lipoperoxidation and the enhancement in superoxide dismutase (SOD) and glutathione (GSH) activities. These safe and bioactive recombinant collagen gels provide a novel approach for sunburn repair and show potential for long-term cosmetic benefits.
