Abstract ：
As the primary electrolyte in salt-containing foods, NaCl governs interparticle repulsions and water partitioning across polymer networks. The mechanisms by which NaCl tunes electrostatic screening, hydration, and interpolymer association in HPCS-XG gels remain insufficiently defined. Here we integrate RVA, zeta-potential, LF-NMR, oscillatory/steady rheology, FTIR/XRD, and SEM to establish a salt-mediated mechanism that links ionic strength to gelatinization, network assembly, and water dynamics. NaCl decreases the absolute zeta-potential, contracts XG coils, and tightens HPCS-XG contacts while reducing effective water availability and perturbing hydrogen-bonding. These coupled effects suppress granule swelling and amylose leaching (19.92 -> 12.02 g/g; 13.9 -> 8.38 %), increase apparent solubility (18.0 -> 63.5 %), and shorten the long-T-2 water population (1126 -> 464 ms). At moderate ionic strength, reinforced interpolymer association yields a viscosity maximum (similar to 1246 cP at 0.5 M) and higher optical clarity; at 1.0 M, hydration limitation and restricted chain mobility outweigh associative gains, producing softer weak-gel networks (G 'down arrow, tan delta up arrow) and reduced thixotropic recovery. Pasting temperature increases with salinity, and particle size shifts downward, consistent with suppressed swelling and screened interparticle repulsions. Microstructural evidence corroborates this pathway: lamellar matrices evolve into flocculated, particulate networks with increasing salinity; FTIR indicates no new covalent functionalities, and XRD reveals salt crystallites in dried gels. Collectively, the data converge on a unifying mechanism in which NaCl tunes electrostatic screening and hydrogen-bond architecture to control granule swelling, chain association, and water partitioning, defining a concentration-dependent optimum for viscosity and clarity and a predictable softening beyond 0.5 M. These rules provide actionable levers for designing salt-containing foods with targeted texture, stability, and processing robustness.

Abstract ：
金针菇营养丰富，适量添加于肉糜制品有望改善其质地和风味，但过量添加可能产生负面作用。以猪肉丸为对象，添加质量分数0、1%、3%、5%的金针菇粉，采用模糊数学感官评价法结合电子舌对猪肉丸感官品质进行评定，并测定其保水性、蒸煮损失率、色泽、质构和滋味等理化指标，借助微观结构观察和水分分布分析探讨金针菇粉作用机理。结果表明：金针菇粉添加可显著提高猪肉丸的保水性，降低蒸煮损失，其中添加质量分数3%时效果较佳，水分保持率达96.45%,蒸煮损失率降至5.81%,综合感官评分最高(3.415分)。与对照组相比，添加3%金针菇粉的猪肉丸的硬度和咀嚼性适度降低，使产品更嫩滑多汁，鲜味显著增强，色泽呈现适宜的淡褐色，风味更加丰富。核磁共振分析显示，添加质量分数3%的金针菇粉可使猪肉丸束缚水的能力最强，水分子与基质结合最紧密；扫描电镜观察到3%添加量下猪肉丸凝胶网络结构最致密且平滑，孔隙较少。添加质量分数3%的金针菇粉显著改善了猪肉丸的综合品质。研究旨在为金针菇粉在肉糜制品中的应用提供理论基础和技术参考。

Abstract ：
文章以大黄鱼鱼皮中提取的鱼皮明胶（fish skin gelatin,FSG）为主体材料，通过乳液模板法制备鱼皮明胶-透明质酸（fish skin gelatin-hyaluronic acid,FSG-HA）复合微球，再利用单宁酸（tannic acid,TA）对复合微球混合交联，构建具有高抗氧化及抗菌活性的单宁酸改性鱼皮明胶-透明质酸（FSG-HA/TA）复合微球。采用动态光散射仪、透射电子显微镜（transmission electron microscope,TEM）、激光扫描共聚焦显微镜（confocal laser scanning microscope,CLSM）、傅里叶变换红外光谱仪（Fourier transform infrared spectrometer,FTIR）和紫外-可见分光光度计等表征FSG-HA和FSG-HA/TA的微观形貌和结构，测定其抗氧化及抗菌活性。结果表明：FSG-HA和FSG-HA/TA均表现出球形结构，单宁酸的交联改性降低了FSG-HA的粒径分布，增强了鱼皮明胶与透明质酸之间的氢键作用，使微球结构更紧密且均匀；FSG-HA和FSG-HA/TA对DPPH自由基和ABTS阳离子自由基的清除率具有质量浓度依赖性，清除率最高分别达93.75%和67.63%。此外，改性后FSG-HA/TA对金黄色葡萄球菌和大肠杆菌的抑制效果显著，尤其是对金黄色葡萄球菌的最高抑菌率达95%。因此，FSG-HA/TA具有较强的抗氧化和抗菌性能，作为食品保鲜和生物医药领域的功能性材料具有巨大的应用潜力。

Abstract ：
This study proposes a compound low-sodium alternative salt (CLSAS) formulation (2.4% sodium chloride, 0.8% K lactate, 0.4% magnesium chloride, 0.4% Ca ascorbate, 0.2% L lysine, and 4% sorbitol) combined with vacuum tumbling for beef marination. The effects of 4% NaCl static marination (F), CLSAS static marination (L), and CLSAS vacuum tumbling (VT-L) on the physicochemical properties, water distribution, and microstructure of marinated beef were evaluated. Compared with F, L maintained similar yield and color, reduced cooking loss, and improved texture while lowering sodium content. VT-L further enhanced product yield, water content, color, texture, and tenderness. Both CLSAS and vacuum tumbling reduced the relaxation time of immobilized water, promoted orderly formation of protein structure, and altered the microstructure of myogenic fibers. VT-L additionally improved the water-holding capacity of myofibrils and further reduced the relaxation times of immobilized and free water. Overall, VT-L could be an effective approach for enhancing the quality of low-sodium meat products, providing a feasible basis for the industrial application of CLSAS for low-sodium marinated meat products.

Abstract ：
Flammulina velutipes is rich in nutrients and its appropriate addition to minced meat products is expected to improve their texture and flavor, although excessive addition may have negative effects. Pork meatballs with varying addition levels (0, 1%, 3%, and 5%) of Flammulina velutipes powder were evaluated. A fuzzy mathematical sensory evaluation method combined with electronic tongue analysis was employed to assess sensory attributes, and physicochemical parameters such as water-holding capacity (WHC), cooking loss rate, color, texture, and taste characteristics were determined. Additionally, microstructural changes and moisture distribution were investigated to clarify the underlying mechanisms. The results demonstrated that the incorporation of Flammulina velutipes powder significantly enhanced the WHC and reduced cooking loss of pork meatballs. The optimal improvement occurred at the 3% addition level, yielding a WHC of 96. 45%, a cooking loss of 5. 81%, and the highest comprehensive sensory score of 3. 415. Compared to the control, pork meatballs with 3% Flammulina velutipes powder exhibited moderately reduced hardness and chewiness, providing a more tender and juicier texture. Umami taste was significantly enhanced, the color showed a suitable pale-brown, and flavor profile was richer. Low-field nuclear magnetic resonance analysis indicated that the 3% group exhibited the highest proportion of bound water, reflecting the strongest water-matrix interactions. Scanning electron microscopy further revealed a denser and smoother gel network structure with fewer voids at the 3% level. In conclusion, the addition of 3% Flammulina velutipes powder significantly improved the comprehensive quality of pork meatballs. This study provided a theoretical foundation and practical reference for applying Flammulina velutipes powder in minced meat products. © 2025 Beijing Technology and Business University, Department of Science and Technology.

Abstract ：
Enhancing the stability and the reusability of ulva polysaccharide lyase (UPL) is crucial for the efficient production of reducing sugars from ulva polysaccharides, which are vital for their broad applications in functional foods. In this study, we innovatively developed a self-immobilized UPL by fusing the enzyme with ferritin, leading to the spontaneous formation of micron-sized ulva polysaccharide lyase supraparticles (mUPLSPs). This novel system streamlines the enzyme purification and immobilization process into a single step, effectively circumventing the need for conventional, laborious chromatographic methods. The mUPLSPs exhibited superior stability and reusability, maintaining over 80% of their initial activity after five cycles of use. When compared to free UPLs, mUPLSPs displayed enhanced thermal and pH stability, resulting in a 252% increase in the yield of reducing sugars after a 40-hour reaction period. The ferritin-tagged, self-immobilization strategy not only provides a scalable and cost-efficient approach to the sustainable production of reducing sugars from ulva polysaccharides but also holds significant potential for industrial-scale applications.

Abstract ：
The long-term sustainable development of flexible electronic devices is limited by a reliance on synthetic polymers that pose dangers for humans and potentially severe ecological problems, as well as a reliance on conventional processing methods. This work aims to exploit 3D printing to develop natural biogels composed of fish gelatin and high acyl gellan gum for use as flexible sensors. The electrical conductivity and mechanical strength were remarkably enhanced through the environmentally friendly enzyme (transglutaminase) cross- linking and non-toxic ethanol modification treatment, which allows the development of 3D printed sensors for temperature, strain, and stress sensors. The hydrogel exhibits excellent mechanical and electrical properties as strain sensors, with Young's modulus and tensile strength of 20.7 f 1.38 kPa and 0.14 f 0.01 MPa, respectively, and an ultimate strain of 270.54 f 16.23 %, which is conducive to a comfortable wearing experience. Moreover, the obtained sensors exhibited ultra-low latency (6.1 f 1.47 ms), good durability (withstanding 1000 cyclic stretching) and high monitor sensitivity (GF = 2.37 f 0.14) to human body movements; furthermore, the biogel fabricated using this method exhibits complete biodegradation within approximately 20 days, offering innovative prospects for the advancement of eco-friendly materials.
