These structural modifications led to remarkable improvements in the functional properties: the solubility, emulsifying activity index, emulsion stability index, and DPPH radical scavenging rate of the UP-SP/FG conjugates reached 53.7%, 1092.54 m<sup>2</sup>/g, 395.33 min, and 32.85%, respectively. Moreover, emulsion gels stabilized with UP-SP/FG glycosylated conjugates displayed smaller droplet sizes, more uniform size distribution, and enhanced oxidation stability compared to those stabilized with SP/FG glycosylated conjugates. These findings indicate that the combined strategy of ultrasound-assisted pH-shifting and glycosylation conjugation with FG significantly enhances the functional properties of SP, providing a strong foundation for broadening its applications in emulsion-based systems.</div></div>","PeriodicalId":48640,"journal":{"name":"Food Structure-Netherlands","volume":"48 ","pages":"Article 100531"},"PeriodicalIF":5.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147995204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
