Polysaccharide was extracted from Eucommia ulmoides leaves using a microwave-assisted hot water method, and subsequently, the polysaccharide\u2013iron complex was synthesized through co-thermal synthesis with FeCl3. The physicochemical properties, structure, and thermal stability of the complex were analyzed using FE-SEM, SEC-MALLS, FT-IR, XRD, and DSC techniques. Furthermore, the antioxidant activity of the polysaccharide\u2013iron complex was evaluated through an experiment in vitro. The results revealed that the polysaccharide\u2013iron complex had an iron content of 6.1% and an average particle size of 860.4 nm. The microstructure analysis indicated that the polysaccharide\u2013iron complex possessed a flaky morphology with smooth and compact surfaces. Moreover, the formation of the Fe3+ complex did not alter the structural framework of the polysaccharide; instead, it enhanced the polysaccharide\u2019s thermal stability. Compared to traditional iron supplements, the E. ulmoides-derived polysaccharide\u2013iron complex demonstrated significant antioxidant activity. Therefore, this novel compound exhibits significant potential as a viable iron supplement.<\/jats:p>","DOI":"10.3390\/foods13142302","type":"journal-article","created":{"date-parts":[[2024,7,22]],"date-time":"2024-07-22T12:20:38Z","timestamp":1721650838000},"page":"2302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Preparation and Performance Evaluation of Polysaccharide\u2013Iron Complex of Eucommia ulmoides"],"prefix":"10.3390","volume":"13","author":[{"given":"Mengpei","family":"Liu","sequence":"first","affiliation":[{"name":"Key Laboratory of Cold Chain Food Processing and Safety Control, Ministry of Education, College of Food and Bioengineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1516-1419","authenticated-orcid":false,"given":"Yan","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tree Genetics and Breeding, Key Laboratory of Non-Timber Forest Germplasm Enhancement & Utilization of State Administration of Forestry and Grassland, Research Institute of Non-Timber Forestry, Chinese Academy of Forestry, Zhengzhou 450003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cold Chain Food Processing and Safety Control, Ministry of Education, College of Food and Bioengineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cold Chain Food Processing and Safety Control, Ministry of Education, College of Food and Bioengineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lihua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Cold Chain Food Processing and Safety Control, Ministry of Education, College of Food and Bioengineering, Zhengzhou University of Light Industry, Zhengzhou 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0307-1237","authenticated-orcid":false,"given":"Lu","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Tree Genetics and Breeding, Key Laboratory of Non-Timber Forest Germplasm Enhancement & Utilization of State Administration of Forestry and Grassland, Research Institute of Non-Timber Forestry, Chinese Academy of Forestry, Zhengzhou 450003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jiang, Y., Zhang, S., Li, M., Zhang, R., Zhang, H., Zheng, Y., Zhang, D., and Wu, L.
