Abstract ：
为改善鱼糜凝胶特性，在鲢鱼鱼糜中添加质量分数为2%~10%的海带全粉（Laminaria japonica powder，LJP）制备鱼糜凝胶。分析LJP添加量对鱼糜凝胶的凝胶强度、质构、持水性、流变特性、化学作用力、肌原纤维蛋白（Myofibrillar protein，MP）二级结构、色泽及微观结构的影响。探究LJP改善鱼糜凝胶品质的内在原因。结果表明，LJP的添加显著提高了鱼糜凝胶的凝胶强度、硬度及持水性，随LJP添加量的增加，这三项指标呈先升高再降低趋势，并在添加量8%时达到最大值，而添加量10%时三项指标则显著下降；LJP对鱼糜溶胶的粘度、稳定性和储能模量（G'）也有显著的提升作用，能够促进弹性凝胶的形成，但添加量过高（10%）则对弹性凝胶具有一定的负面作用。LJP中所富含的多糖在鱼糜中可以与MP形成多糖-MP相互作用，使鱼糜凝胶中氢键和离子键作用力显著增加、MP二级结构向β-折叠转变，从而形成网络孔径小、结构更加致密的鱼糜凝胶。结论：适宜的LJP添加量（6%～8%）可以通过影响鱼糜凝胶特性、凝胶化学作用力及MP二级结构改善鱼糜凝胶品质。

Abstract ：
本实验通过超声辅助酶解技术制备鸡皮蛋白抗冻肽(chicken skin antifreeze peptides,CsAFPs),研究CsAFPs对鸡肉糜稳定性的影响.结果表明,CsAFPs中85.88％为180～3 000 Da的短肽,其亲水性强,且表现出良好的热滞活性和重结晶抑制活性,能够使体系的冰晶含量降低(26.03±0.40)％,玻璃化转变温度提高7.3℃.CsAFPs与鸡肉糜风味协调一致,添加质量分数2％的CsAFPs能够显著提升鸡肉糜的持水力,同时保持色泽稳定,展现出应用潜力.经过4 次冻融循环后,添加2％CsAFPs的鸡肉糜凝胶保水能力、弹性、回复性的下降幅度均显著低于空白冻融组.多光谱技术分析表明CsAFPs能够防止蛋白质冷冻胁迫下的聚集变性,经过冻融循环后2％CsAFPs处理的肉糜中肌原纤维蛋白峰谷比值r比空白冻融组高.本研究有助于更好理解抗冻肽在冷冻肉糜中的保护机制,有望为肉糜提供一种有前景的低甜度、低热量的新型冷冻保护剂.

Abstract ：
Pseudomonas aeruginosa, recognized for its biofilm production and secretion of virulence factors, posing a severe threat in areas such as clinical infections, food contamination, and marine biofouling. To address this, a new type of zinc-binding peptide (CSSP-Zn) was prepared from crimson snapper scales peptides (CSSP) and goslarite, and its antibacterial and anti-quorum-sensing activities toward P. aeruginosa PAO1 were exploited. Results indicated that CSSP-Zn induced planktonic strain PAO1 membrane injury via inhibiting expression levels of cell integrity genes, targeting microbial-specific membrane constituents, disrupting proton motive force, and causing metabolic disturbances. Meanwhile, CSSP-Zn decreased virulence factors pyocyanin, protease and rhamnolipid secretion, while considerably inhibiting quorum sensing-related genes (las, pqs and rhl) expression and decreasing bacterial abundance and pathogenicity in fish models. Moreover, CSSP-Zn not only effectively hindered biofilm formation but also disassembled preformed ones, thus disrupting biofilm topology. Taken together, utilizing food byproducts to obtain CSSP-Zn could help recycle food resources and provide insight into controlling planktonic and biofilm strain PAO1 contamination.

Abstract ：
Polyphenols, abundant in tea, fruits, vegetables, and other plant-derived foods, have emerged as key bioactive ingredients in the field of nutritional epigenetics. These polyphenols can modulate epigenetic modifications through endogenous metabolic pathways that are highly sensitive to food signals. Among these, the methionine cycle plays a central role in maintaining the homeostasis of DNA, histone, and RNA methylation by controlling the cellular supply of S-adenosylmethionine (SAM), the universal methyl donor. Dietary polyphenols influence this cycle through multiple mechanisms, including the regulation of methionine adenosyltransferase activity, modulation of SAM biosynthesis, and promotion of S-adenosylhomocysteine clearance. These actions help restore methylation balance and contribute to the dietary prevention of metabolic, inflammatory, and age-related diseases. Furthermore, polyphenols are biotransformed in the gut microbiota to produce metabolites that further influence methionine metabolism and its associated epigenetic modifications. This review provides an overview of dietary polyphenols as functional food supplements that play a role in methionine metabolic homeostasis and epigenetic modification. This review provides new perspectives for the development of precision nutrition strategies, functional foods, and chronic disease prevention approaches. © 2025 Taylor & Francis Group, LLC.

Abstract ：
This study aims to explore the cryoprotective mechanisms of food-derived hydrolyzed peptides and develop novel cryoprotectants to enhance the quality of frozen foods. Evynnis japonica scale antifreeze peptides (Ej-AFP) were prepared using enzymatic hydrolysis, which had a 4-fold increase in protection efficiency for surimi compared to traditional cryoprotectants. Furthermore, Ej-AFP was able to control 63.60% of the ice crystals to sizes below 600 mu m2. Three antifreeze peptide sequences were purified by using ice-affinity techniques and peptidomics. These sequences demonstrated a 21.75% enhancement in antifreeze activity and an increase of 1 degrees C in thermal hysteresis activity compared to Ej-AFP. Molecular simulation-elucidated ice-binding surface interacts with ice crystals through hydrogen bonds, while the nonice-binding surface disrupts the orderly arrangement of water molecules. This results in a tightly structured hydration layer around the peptide, increasing the curvature of the ice crystal surface and thereby demonstrating significant antifreeze activity in controlling ice crystal growth.

Abstract ：
This study assessed the effects of antifreeze peptides (CsAFPs) produced by enzymatical hydrolysis of chicken skin on chicken mince stability. CsAFPs, 85.88% of which were short peptides (180–3 000 Da), showed high hydrophilicity and strong thermal hysteresis activity and ice recrystallization inhibition activity, reducing the ice crystal content by (26.03 ± 0.40)% and raising the glass transition temperature by 7.3 ℃. The flavor of CsAFPs was well coordinated with that of chicken mince and the addition of 2% CsAFPs enhanced the water-holding capacity of chicken mince without color change. After four freeze-thaw cycles, mince added with 2% CsAFPs showed less reductions in water-holding capacity, elasticity, and resilience than did the control group. Ultraviolet (UV) absorption and Fourier transform infrared spectroscopy (FTIR) indicated that CsAFPs could prevent the aggregation and denaturation of proteins under freezing stress. After freeze-thaw cycles, the r value of myofibrillar protein in the mince with 2% added CsAFPs was higher than the control group without CsAFPs. This study contributes to a better understanding of the protective mechanisms of CsAFPs in frozen meat and highlights that CsAFPs are promising novel low-sweetness and low-calorie cryoprotectants for meat products. © 2025 Chinese Chamber of Commerce.

Abstract ：
Immune-mediated inflammatory diseases (IMIDs) are characterized by chronic inflammation and frequent recurrence, and intervention strategies are urgently needed. Gut microbiota has been shown to play an active role in immune activation and regulation, with food-derived bioactive peptides (FDBPs) effectively improving the homeostasis of the gut microbiota. The potential role of FDBPs in IMIDs intervention is receiving more and more attention due to their ability to regulate gut microbiota. This review first addresses the way FDBPs regulate the gut microbiota, comprehensively summarizing the factors that affect its homeostasis and focusing on the interactions between gut microbiota and IMIDs through signaling pathways and the microbiota-gut-X axis. The review on the role of gut microbiota metabolites emphasizes the importance of FDBPs in regulating the gut microbiota and their potential for nutritional intervention in IMIDs. There can be direct and indirect between gut microbiota and IMIDs. Since FDBPs can regulate the gut microbiota through multiple pathways, dietary intervention, especially peptide diets as dietary supplements, seems to be a reliable strategy for the improvement and alleviation of IMIDs. In the future, we will focus on the structure and bioavailability of FDBPs, aiming to demonstrate, through this structure-function relationship, the different effects of the gut microbiota on IMIDs.

Abstract ：
Traditional cryoprotectants such as sucrose and phosphates are limited by safety and flavor concerns, creating a demand for food-grade alternatives. Here, Bos taurus domesticus gelatin antifreeze peptides (BtAFP) were investigated for their dual cryoprotective mechanisms. Rheological analysis showed that BtAFP enhanced gel elasticity and delayed freezing, exhibiting superior cryoprotection compared with bovine serum albumin. LC-MS/MS identified 452 peptides, from which five nontoxic collagen-derived candidates with amphiphilic alpha-helix/beta-sheet motifs were selected. Ice recrystallization assays showed that the majority of ice crystals in purified peptide solutions were concentrated below 1000 mu m2. Differential scanning calorimetry indicated that GKEAFP, GLPAFP, and GLRAFP most effectively inhibited ice growth. Molecular docking demonstrated stable peptide-ice and peptide-alpha-lactalbumin interactions, with GLPAFP notably stabilizing protein structures through extensive hydrogen bonding and surface interactions. These findings suggest that gelatin-derived antifreeze peptides suppress ice recrystallization and stabilize proteins via amphiphilic ice-binding motifs, providing promising natural cryoprotectants for frozen food applications.

Abstract ：
Developing emulsifier-free intelligent films constitutes a dependable strategy for securing food supply chain safety. Here, zinc-binding peptides derived from Crimson Snapper scales (CSSP-Zn) and Jufeng grape pomace anthocyanin (JGA) were incorporated into a gelatin (GL) matrix to fabricate three types of films: GL film, GL film with CSSP-Zn and GL film with both JGA and CSSP-Zn. The GL film is a pure GL film, while the GL film incorporating CSSP-Zn exhibits antimicrobial activity, and the GL film containing both JGA and CSSP-Zn functions as an antimicrobial, pH-responsive intelligent film. Compared with the pure GL film, incorporating CSSP-Zn and JGA enhanced mechanical strength, water resistance and barrier properties via hydrogen bonding and Zn2+ ligand interactions. The intelligent film exhibited long-lasting antimicrobial activity, maintaining potent microbicidal efficacy even after 3 months of storage. Additionally, it demonstrates excellent antioxidant properties (DPPH and ABTS scavenging rates > 83 %), pH-responsive color changes, cytocompatibility (cell viability > 80 %) and biodegradability (degradable within 15 days in soil). When applied to Penaeus orientalis, the intelligent film effectively shields the shrimp from UV light, free radicals and microbes, delaying melanosis and spoilage while preserving texture, sensory attributes and nutrient profile, ultimately extending shelf life. Overall, incorporating CSSP-Zn and JGA can prepare a high-performance, eco-friendly GL-based intelligent film, providing valuable insights for sustainable food packaging. © 2025
