The optimal extraction process conditions of SFPs are as follows: an ethanol volume fraction of 28%, a liquid\u2013solid ratio of 29 mL\/g, an extraction temperature of 80 \u00b0C, and an extraction time of 3.2 h. After enrichment by D101 macroporous resin, the purity of SFPs increased from 1.20 \u00b1 0.08% to 10.78 \u00b1 0.25%, increasing by approximately 8 times. SFPs were mainly composed of polyphenols, flavonoids, and polysaccharides. Furthermore, after identification by HPLC-QQK-ESI-MS\/MS, they were found to contain 11 phlorotannins (mainly of the fuhalol type), 2 flavonoids, etc. In three antioxidant evaluation systems (DPPH free radical scavenging ability, reducing power, and total antioxidant capacity), the enriched SFPs all exhibited superior activities compared to tea polyphenols. The research results provide a theoretical basis and experimental evidence for the development of a new type of food preservative based on SFPs.<\/jats:p>","DOI":"10.3390\/foods14193317","type":"journal-article","created":{"date-parts":[[2025,9,25]],"date-time":"2025-09-25T07:46:49Z","timestamp":1758786409000},"page":"3317","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Extraction, Enrichment, Characterization, and Antioxidant Activities of Sargassum fusiforme Polyphenols"],"prefix":"10.3390","volume":"14","author":[{"given":"Hui","family":"Wang","sequence":"first","affiliation":[{"name":"Jiangsu Key Laboratory of Marine Bioresources and Environment, School of Ocean Food and Biological Engineering, Jiangsu Ocean University, Lianyungang 222005, China"},{"name":"Lianyungang Customs Comprehensive Technology Center, Lianyungang 222042, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Zhang","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Marine Bioresources and Environment, School of Ocean Food and Biological Engineering, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiqin","family":"Yang","sequence":"additional","affiliation":[{"name":"Lianyungang Quality and Technology Comprehensive Inspection and Testing Center, Lianyungang 222000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linwu","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Marine Bioresources and Environment, School of Ocean Food and Biological Engineering, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4906-2790","authenticated-orcid":false,"given":"Lei","family":"Guo","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Marine Bioresources and Environment, School of Ocean Food and Biological Engineering, Jiangsu Ocean University, Lianyungang 222005, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Meinita, M.D.N., Harwanto, D., Sohn, J.H., Kim, J.S., and Choi, J.S.
