This study unveils thermal pre-treatment as a breakthrough to customize curdlan gels. Preheating suspensions (40–80 °C) before 90 °C gelation revealed that 48–58 °C — the gel transition range — dramatically weakens the network. Gels softened, with reduced hardness and viscoelasticity compared to untreated CU-90. Cryo-scanning electron microscopy revealed that thermal pre-treatment altered the gel microstructure, increasing pore size and reducing network density. Furthermore, Fourier-transform infrared spectroscopy and X-ray diffraction analyses suggested that preheating disrupted intermolecular hydrogen bonding, influencing triple-helix formation, and subsequently impacting the mechanical properties of the gel. Based on these findings, we propose that thermal pre-treatment at 50 °C influences curdlan gelation by initially promoting network formation, subsequently limiting chain mobility, and ultimately modulating triple helix formation, thereby controlling the final network structure and mechanical properties. Ultimately, the 4 % CU-50-90 formulation exhibited textural properties comparable to cooked porcine adipose tissue, highlighting its potential as a fat replacer in food formulations. These results introduce a novel, environmentally benign, and additive-free strategy for modulating curdlan gel properties, thus expanding its potential within the industry.</div></div>","PeriodicalId":261,"journal":{"name":"Carbohydrate Polymers","volume":"367 ","pages":"Article 123982"},"PeriodicalIF":10.7,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144518383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
