摘要：
Aging isda natural and inevitable physiological process that poses a serious threat to physical health, leading to age-related diseases and placing a heavy burden on the public health system. This study explores intervention measures to promote healthy aging and prolong lifespan. Anthocyanins (ACNs), as a class of flavonoids widely presented in fruits, vegetables and grains, exhibit strong antioxidant and anti-inflammatory activities. Recent studies indicate that ACNs exert health effects primarily by interacting with gut microbiota. Here, we introduced the digestion and absorption of ACNs, and mainly elaborated on the role of ACNs in delaying aging through gut microbiota. In addition, we described the changes in gut microbiota mediated by ACNs and their impact on age-related chronic diseases, including cardiovascular diseases, neurodegenerative diseases, cancer, and sarcopenia. Therefore, ACNs have a broad application prospect in the development of functional foods with ant-aging effects by regulating gut microbiota 1 2025 Beijing Academy of Food Sciences.

摘要：
Cadmium (Cd) is a widespread and highly toxic environmental pollutant, seriously threatening animal and plant growth. Therefore, monitoring and employing robust tools to enrich and remove Cd from the environment is a major challenge. In this work, by conjugating a fluorescent indicator (CCP) with a functionalized glass slide, a special composite material (CCPB) was constructed to enrich, remove, and monitor Cd2+ in water rapidly. Then Cd2+ could be effectively eluted by immersing the Cd-enriched CCPB in an ethylenediaminetetraacetic acid (EDTA) solution. With this, the CCPB was continuously reused. Its recovery of Cd2+was above and below 100 % after multiple uses by flame atomic absorption spectrometry (FAAS), which was excellent for practical use in enriching and removing Cd2+ in real aqueous samples. Therefore, CCPB is an ideal material for monitoring, enriching, and removing Cd2+ in wastewater, providing a robust tool for future practical applications of Cd enrichment and removal in the environment.

摘要：
This study aimed at gaining insight into the mechanism of interactions between pectin (PE), starch and unsaturated fatty acids (UFAs) in relation to structure, in vitro digestibility and release properties of starch. Due to the barrier and encapsulation effects of PE, the complexing behavior of potato starch (PtS) with linoleic acid (LOA) was enhanced, which increased the complexing index, the compactness of network structure, short-range ordered structure and relative crystallinity of PtS-LOA-PE films. These structural changes resulted in the increases of slowly digestible starch and resistant starch and in the decreases of first-order rate coefficient in PtS-LOA-PE films. Besides, the in vitro release results also showed that the release properties of PtS-LOA could be controlled by the PE addition with the decreases in LOA release rate and increase in LOA bioavailability under simulated gastrointestinal conditions. Notably, at different PtS-LOA:PE ratios, the PtS-LOA-PE film with the PtS-LOA:PE ratio of 5:1 showed the better complexing degree, structural order, anti-digestibility and colon-targeted release properties than other PtS-LOA-PE films. These results indicated that PE influenced the release properties of the PtS-LOA-PE films, which was closely related to their complexing degree, structural order, and digestibility. This study provided new insights into the design of resistant films for delivery of UFAs to colon.
摘要：
The deterioration of food freshness and occurrence of spoilage is attributed to adverse external conditions during storage, leading to unnecessary waste and posing food safety concerns. Therefore, it is imperative to develop packaging that monitors and maintains food freshness. Intelligent and active packaging precisely meets these desired requirements. Intelligent packaging has the potential to offer real-time feedback on environmental changes within the packaging, providing valuable information about food quality and safety. On the other hand, active packaging represents a novel approach that incorporates active ingredients, such as antimicrobials into packages to enhance food quality. This review highlights recent advancements in dual -functional packaging utilizing various plant essential oils and pH -sensitive natural pigments. It explores different methods, with a focus on electrospinning, and also discusses existing challenges and future trends. This information aims to assist in the development of packaging systems, offering a new direction for the development of antibacterial and pHsensitive packaging.

摘要：
Food-derived multifunctional peptides offer numerous health benefits through different biochemical pathways. However, their impact on aging-related atherosclerotic cardiovascular disease (ASCVD), especially atherosclerosis, remains underexplored despite cardiovascular disease (CVD) being the leading cause of death globally. In this study, NHANES data and Mendelian randomization were used to analyze the association between lipid metabolism disorders, systemic immune responses, dietary inflammatory index, and ASCVD. The results showed that they were all positively correlated with ASCVD. A dietary intervention was used to induce a mouse model of atherosclerosis through a high-fat diet (HFD). Our findings demonstrate that rice bran peptide could mitigate the typical pathological features of atherosclerosis. Molecular docking analysis further predicted that lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a key target of rice bran peptide. This prediction was validated through a two-cell model of endothelial cells and lox-1-interfered macrophages. Therefore, targeting LOX-1 with rice bran peptide inhibits the excessive uptake of oxidized LDL (ox-LDL) by macrophages, thereby hindering the mass production of foam cells, which is crucial in preventing the early onset of atherosclerosis.
摘要：
Momordica charantia L. is a kind of vegetable with medicinal value. As the main component of the vegetable, Momordica charantia polysaccharides (MCPs) mainly consist of galactose, galacturonic acid, xylose, rhamnose, mannose and the molecular weight range is 4.33×10(3)-1.16×10(6)Da. MCPs have been found to have various biological activities in recent years, such as anti-oxidation, anti-diabetes, anti-brain injury, anti-obesity, immunomodulatory and anti-inflammation. In this review, we systematically summarized the extraction methods, structural characteristics and physicochemical properties of MCPs. Especially MCPs modulate gut microbiota and cause the alterations of metabolic products, which can regulate different signaling pathways and target gene expressions to exert various functions. Meanwhile, the potential structure-activity relationships of MCPs were analyzed to provide a scientific basis for better development or modification of MCPs. Future researches on MCPs should focus on industrial extraction and molecular mechanisms. In East Asia, Momordica charantia L. is used as both food and medicine. It is not clear whether MCP has its unique biological effects. Further study on the difference between MCPs and other food-derived polysaccharides will be helpful to the development and potential application of Momordica charantia L.
摘要：
Myocardial ischemia-reperfusion (MI/R) not only causes cardiac damage, but also causes severe renal damage. T8 is the 8th peptide identified by peptiomics in digested yak milk dregs and our previous studies showed that T8 had strong antioxidant activity. This study evaluated the protective effects and molecular mechanisms of MI/R-induced kidney injury in rats. Our results indicated that peptide T8 could increase ejection fraction (EF) and shortened fraction (FS), and degraded ST segment elevation, which ameliorated cardiac function in the MI/R rats. Peptide T8 could increase activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX), and decreased the contents of malondialdehyde (MDA), serum creatinine (Scr) and blood urea nitrogen (BUN), which could ameliorate renal insufficiency. Peptide T8 and kidney injury-related targets in the MI/R-damaged rats were obtained from network pharmacology analysis. KEGG analysis revealed that T8 might affect 54 signaling pathways and 13 key targets were obtained by PPI network analysis. The binding affinity of peptide T8 to Keap1 was found to be the strongest by molecular docking analysis. In the H2O2-induced HEK293 cell model, peptide T8 decreased reactive oxygen species (ROS) content and changed the expression ratio of Bcl-2 and Bax, thereby inhibiting mitochondria-dependent apoptosis. Further studies indicated that T8 could regulate Nrf2 pathway and downstream target genes such as NQO1, which could reduce oxidative stress-induced damage. These results suggest that peptide T 8 can exert renal protection via regulating Nrf2 pathway and apoptosis-related genes.

摘要：
It is of great significance to develop natural active substances for treating Alzheimer's disease (AD). We constructed an AD cell model using A beta(25-35)-induced PC12 cells to assess isolated components from Tibet wild Gymnadenia crassinervis protective and reparative effects against A beta(25-35)-induced cell injury. The results indicated that the active fraction extracted and isolated from Gymnadenia crassinervis strongly inhibited acetylcholinesterase (AChE) with an excellent IC50 value as low as 135.86 +/- 5.59 mu g/mL. The main compound of the Gymnadenia crassinervis active fraction was preliminarily identified as dactylorhin A by LC-MS. The high-concentration group, treated with 10 mu g/mL of the Gymnadenia crassinervis active fraction, exhibited significantly protective effects, the treatment of which enhanced cell viability and mitigated cell shrinking induced by A beta(25-35). The ROS level and MDA content in the high-concentration group cells decreased by approximately 28% and 30%, respectively, while the activities of SOD and CAT even increased by about 92% and 221%, respectively. In addition, Western blotting analysis showed that the Gymnadenia crassinervis active fraction inhibited apoptosis. Therefore, these findings suggest that the Gymnadenia crassinervis active fraction can repair A beta(25-35)-induced cell injury, protect against A beta toxicity, and hold potential in both preventive and therapeutic aspects of AD.

摘要：
Investigation into the relationship between surface structure and catalytic performance is pivotal for guiding the preparation of high-performance nanocatalysts. However, there is a lack of an effective strategy for fine-tuning the surface structure. In this paper, eight kinds of Au nanocubes (AuNCs) with structures ranging from concave to flat to convex were synthesized using trace amounts of Cu2+, and their surface structure-dependent catalytic performance was investigated. In the synthesis, H2O2 reduced Au3+ to Au+ in alkaline CTAB solutions first, and then ascorbic acid was added to initiate the growth of AuNCs. Increasing the Cu2+ amounts led to an evolution of concave -> flat -> convex surfaces, corresponding to transitions of {hk0} facets. The mechanism involves Cu2+ catalyzing the reaction between H2O2 and ascorbic acid to produce hydroxyl radicals, which promote increased Au-0 deposition on the surface center. More importantly, the catalytic performance of AuNCs decreases as the surface evolves from concave to flat to convex. This study demonstrates for the first time that the use of simple substances induces concavo-convex transformation of AuNCs, and elucidates the relationship between surface structure and catalytic performance of AuNCs.
