This adsorbent facilitated magnetic solid phase extraction (MSPE) of six AFs prior to LC-MS/MS analysis, achieving one-step purification and enrichment in food matrices. The successful synthesis of the adsorbent was confirmed using various techniques, with adsorption capacities ranging from 46.7 mg/g to 52.3 mg/g. The adsorbent exhibited exceptional adsorption performance in real samples, with recoveries ranging from 80.3 % to 105.6 %, and notable reusability for more than seven cycles. The adsorption mechanism was investigated by density-functional theory and attributed to synergetic effects involving electrostatic and π-π stacking interactions. HPLC-MS/MS quantification revealed strong linear relationships within the 0.01–100 μg/kg range (R2 > 0.9983). The limits of detection ranged from 0.0016 μg/kg to 0.0099 μg/kg, indicating high sensitivity. The newly constructed COF adsorbents exhibit considerable potential for diverse applications in analytical fields that target various hazardous substances.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"33 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142908548","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}

To overcome them, extensive research and development efforts have been directed toward creating effective delivery systems. Among them, the positive synergistic effect between biomaterials can be used to refine the design of delivery systems. Understanding the relationship between structure and function aids in tailoring applications to specific needs. This review outlines the challenges associated with delivering AST and reviews the mechanisms involved in creating delivery systems, specifically focusing on the structure-function relationship of biomaterials. It comprehensively introduces the positive synergistic effect of biomaterials with enhancing the functional properties of AST, and analyzes the impact of designed structures on function regulation and the application prospects of the delivery system in the food industry. The future demand for efficient delivery of AST will increasingly depend on the positive synergistic effect between biomaterials.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"14 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142908573","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}

Traditional methods for studying lipolysis face challenges in sample representativeness and pre-treatment, and cannot measure real-time lipolysis in vivo. Thus, non-invasive techniques like magnetic resonance imaging (MRI) need to be developed. This study assessed the MRI water-fat separation method for monitoring in vitro intestinal digestion of dairy cream, supported by high-performance thin-layer chromatography (HP-TLC) and time-domain nuclear magnetic resonance (TD-NMR). A clear distinction was found between the T2 of undigested lipids (~120 ms) and lipolytic products (0.1–15 ms). The short T2 of lipolytic products likely results from semi-crystalline structures formed with bile salts. While MRI methods cannot detect such fast-relaxing protons, it effectively quantified lipolysis by tracking the residual undigested lipids, showing high correlation with HP-TLC results (R2 = 0.93 and 0.95 for 13-s and 6-min MRI methods, respectively). The rapid 13-s MRI method offers strong potential for future in vivo applications.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"3 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142908572","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}

To address low stability and bioavailability issues of phenolic compounds, lamellar solids emerge as a promising approach for their loading and stabilization in food, cosmetic, and pharmaceutical applications.A solid phase adsorption procedure was developed here by comparing the properties of eight solids towards GP polyphenols. Magnesium aluminium azelate showed nearly complete adsorption and low release. The adsorption/desorption ability of the selected supports was monitored by HPLC-DAD and spectrophotometry assays. The chemometric approach, based on Principal Component Analysis and k-means clustering, identified three distinct clusters based on solid properties. Additionally, color analysis revealed similarities between residues treated with magnesium aluminium chloride and carbonate. The comprehensive analytical methodology employed for the adsorption/retention of GP polyphenols in lamellar solids is presented herein for the first time.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"55 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142908544","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 developed a new stable isotope chemical labelling coupled with ultra-performance liquid chromatography-tandem mass spectrometry method to detect six amino thiols from fish samples. By the proposed method, amino thiols were labeled after liquid extraction using the stable isotope labeling reagents of iodoacetamide (IAM) and D4-IAM. Desirable recovery and linearity of thiols were achieved in fish samples. The limits of detection (LOD) ranged from 0.2 to 6.5 nmol/g, and the detection sensitivity was improved from 2.6 to 74 folds. The cluster analysis revealed that this method successfully discriminated eight fish species and their sources. Additionally, we found that glutathione and cysteine were significantly correlated with the transportation stress status of golden pompano (Trachinotus ovatus). Overall, this study presents a sensitive and efficient method for the detection of amino thiols from fish samples.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"126 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905514","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}
