Here, starch–unsaturated fatty acid–polyphenol ternary systems were constructed to investigate relationships among molecular interactions, multiscale structures, and digestion properties. Eicosapentaenoic acid (EPA) was associated with V-type amylose ordering consistent with inclusion-complex formation, while the polyphenol-containing systems showed distinct patterns of structural organization. Resveratrol tended to associate with the hydrophobic helical environment, whereas chlorogenic acid showed stronger hydrogen-bond-mediated interaction tendencies around the starch–EPA assembly. Multiscale structural, digestion, and computational analyses revealed distinct associations between polyphenol interaction tendencies and digestion behavior. The RA-containing system showed lower digestibility, suggesting a contribution from structural restriction, whereas the CGA-containing system showed stronger α-amylase inhibition. These findings suggest that polyphenol structure shapes interaction patterns in starch–lipid assemblies and may inform future strategies for modulating starch structure and digestion properties.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"25 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the deposition and coloration capacity of dietary canthaxanthin, astaxanthin, and lutein in egg yolks, focusing on the oxidative stability of canthaxanthin. While physical parameters remained unaltered, canthaxanthin exhibited the highest coloration capacity, rapidly achieving a maximum color score of 16. Conversely, pigment mixtures yielded lower scores, suggesting visual dilution and competitive interactions, while LC–MS/MS revealed an upper limit on carotenoid deposition. Storage trials demonstrated that canthaxanthin-enriched yolks maintained exceptional color stability and chemical retention over 21 days at 4 °C and 15 °C. Notably, canthaxanthin maintained a consistently lower yolk pH throughout storage and attenuated superoxide dismutase (SOD) depletion.

Our prior work has linked arsenic exposure to thyroid cell pyroptosis and consequent tissue injury, yet the underlying molecular mechanism remains unclear. This study interrogated the ERRFI1-ErbB1/ERK axis mediating sodium arsenite (NaAsO2)-induced thyroid injury using in vivo SD rat models and in vitro Nthy-ori 3–1 cells. In rats, NaAsO2 decreased ERRFI1, boosted ErbB1/ERK phosphorylation, and caused thyroid injury and endocrine dysfunction; these adverse effects were partially reversed by the ErbB1 inhibitor erlotinib. In Nthy-ori 3–1 cells, NaAsO2 elicited NLRP3 inflammasome-dependent pyroptosis, repressed ERRFI1, hyperactivated ErbB1/ERK signaling. Pharmacological bidirectional modulation of ErbB1 confirmed its critical role, while ERRFI1 overexpression dampened ErbB1/ERK phosphorylation and mitigated pyroptosis. Collectively, NaAsO2 represses ERRFI1 to hyperactivate ErbB1/ERK, triggering NLRP3 inflammasome-mediated thyroid cell pyroptosis and endocrine dysfunction. These findings define a novel mechanism of arsenic thyrotoxicity and identify the ERRFI1-ErbB1/ERK axis as a promising intervention target.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"281 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peptidomics identified 717, 658, and 514 oligopeptides from human, goat, and cow milk, respectively. Goat milk closely mirrored human milk in length distribution, with both peaking at 4–5 residues, whereas cow milk exhibited a peak at 6–7 residues. Proline was the most abundant amino acid residue across all sources, and goat milk generated significantly higher numbers of short oligopeptides (≤10 residues) than cow milk. Notably, 38 oligopeptides were exclusively shared between human and goat milk, predominantly proline-rich, casein-derived sequences with multiple predicted bioactivities. These findings indicate that goat milk is predicted to offer functional advantages over cow milk for human milk-oriented infant nutrition, primarily through its capacity to generate proline-rich bioactive oligopeptides.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"260 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combination therapy outperformed individual treatments, suppressing pro-inflammatory cytokines and restoring mucosal integrity. Mechanistically, 2′-FL remodeled the gut microbiota, enriched butyrate-producing Lachnospira, promoted SCFA production, and upregulated epithelial adhesion molecules HAS1 and GPC-1, which are associated with enhanced Lachnospira adhesion. In vitro coculture further indicated that B. bifidum B-67 acts as the primary degrader of 2′-FL and supports Lachnospira growth, suggesting a cross-feeding effect. Untargeted metabolomics revealed distinct metabolic alterations, including in bile acid-related pathways, associated with the combination intervention.

The reduction in molecular weight preserved the monosaccharide composition, functional groups, and residue types but significantly decreased their apparent viscosity and converted spatial conformations from compact and rigid triple-helix structures into flexible random coils. All HePs resisted in vitro gastrointestinal digestion and were utilized by gut microbiota. HePs increased the relative abundance of short-chain fatty acid-producing bacteria such as Megamonas, Megasphaera, Bifidobacterium, and Ligilactobacillus. The upregulation effects of HePs on the above intestinal microbiota and short-chain fatty acids were negatively correlated with molecular weight. Molecular weight may affect the modulatory effects of HePs on the dominant intestinal microbiota, functional enzyme expression, and microbial metabolic pathways. These findings may provide a research basis for the development of HePs prebiotic products.","PeriodicalId":41,"journal":{"name":"Journal of Agricultural and Food Chemistry","volume":"9 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
