The volatile profile of the wines was significantly altered, according to the time and stage of maceration. Wines made with pre-fermentation maceration showed a notable increase in the levels of terpenes and esters, and wines from post-fermentation maceration resulted in an increase in oxidation and aging compounds. Projective mapping revealed distinctions in the wines as a function of time and stage of maceration. Wines made with pre-fermentation maceration exhibited floral attributes, citrus and white fruits, and typical varietal aromas. Wine made with post-fermentation maceration showed more complex attributes, such as notes of honey, almonds, freshly cut grass, and apricot. These results provide a basis for developing oenological practices that can contribute to the production of wines with distinct sensory identity.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"98 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165155","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}

Newer advanced extraction techniques such as ultrasound-, microwave-, enzyme-, accelerated solvent-, and supercritical CO₂-assisted extraction has been evaluated to enhance yield, selectivity, and sustainability. Replacing conventional solvents with Natural Deep Eutectic Solvents (NADES) offers in addition a more sustainable and eco-friendly approach. This review provides a brief background on seaweed phenolics, examines extraction challenges, discusses advanced technologies, and explores potential emerging methods that integrate advanced technologies with NADES. It also compares NADES with traditional methods and considers the potential of NADES-extracted seaweed phenolics, offering insights into emerging trends to refine extraction methodologies within a sustainable bioeconomy.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"145 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165069","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}

Residue analysis showed higher accumulation in shoots (1.15–1.32 μmol) than roots (0.0210–0.0678 μmol). Imidacloprid in radish dissipated following first-order kinetics, with a half-life of 18.5 d. Parental imidacloprid was confirmed in roots, while four metabolites, predominantly olefin and 4/5-hydroxy imidacloprid, were identified in shoots. The proposed pathway involves hydrolysis of the imidazole ring to form hydroxyl derivatives, followed by dehydration to olefin products. Notably, dietary risk assessment revealed risk quotient values up to 20 % in some individuals consuming radish leaves, highlighting the need for stricter monitoring. Overall, these findings fill the knowledge gap regarding imidacloprid metabolism in radishes and offer vital insights into optimizing pesticide usage while maintaining food safety.","PeriodicalId":318,"journal":{"name":"Food Chemistry","volume":"8 1","pages":""},"PeriodicalIF":8.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144153810","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}
