Among various structuring agents, rice bran wax (RBX) is a promising candidate for creating three-dimensional networks in liquid vegetable oils. However, the functional success of these systems is heavily dependent on wax composition and processing conditions. This study investigates the impact of RBX compositional profile and oleogelation conditions on the structural stability of sunflower oil-based oleogels. A laboratory-extracted RBX (obtained via an optimised isolation protocol) was compared with two commercial alternatives to evaluate the possible influence of interfering compounds on microstructural assembly. Results show that the compositional profile of the laboratory-purified RBX promotes highly cohesive inter-crystalline interactions, yielding a robust and continuous solid matrix even at low concentration (1%wt) depending on the process conditions. Conversely, the application of mechanical stirring during the oleogelation phase was found to hinder the development of a continuous solid network, promoting the formation of aggregates that led to notable oil separation during storage. Under these dynamic conditions, minor components present in commercial waxes appeared to partially mitigate this aggregation, indicating a clear trade-off between compositional homogeneity and resilience against mechanical stress. These findings demonstrate that high-performance oleogels can be achieved by optimising both wax isolation protocols and environmental conditions during oleogelation. This research provides fundamental insights for future research aimed at incorporating chemically uniform RBX oleogels into complex food matrices as a sustainable alternative to saturated fats, contributing to the development of improved lipid-based food products.</div></div>","PeriodicalId":48640,"journal":{"name":"Food Structure-Netherlands","volume":"50 ","pages":"Article 100568"},"PeriodicalIF":7.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149161219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the open-porosity of aerogels favours rapid absorption of both water and digestive fluids, triggering structural collapse and uncontrolled release of the loaded bioactives. In this study, a hydrophobic coating layer was used to finely modulate bioactive release from aerogels. To this aim, aerogel beads were prepared by gelling whey proteins at the isoelectric pH, followed by solvent exchange and supercritical-CO<sub>2</sub> drying. The resulting beads showed the typical whey protein microaerogel structure, with interconnected globular particles and a defined mesoporous network, providing a specific surface area of 27 m<sup>2</sup>/g estimated by QSDFT analysis, which was suitable for bioactive loading. The microaerogel beads were loaded with vanillin, selected as a representative bioactive molecule, and dip-coated in an ethylcellulose (EC) ethanolic solution at varying concentrations (1, 5, and 10 g/100 g). Coating application resulted in the formation of a protective coating layer, with thickness increasing with the EC concentration in the dipping solution, and this led to a marked reduction in the accessibility of microaerogel mesoporosity to N<sub>2</sub> sorption. Uncoated beads exhibited rapid Fickian diffusion of vanillin, while coating application shifted the transport mechanism toward a slower, barrier-controlled mass transfer. These results support aerogels as innovative food-grade delivery systems for controlled release of compounds with target functionalities in foods.</div></div>","PeriodicalId":48640,"journal":{"name":"Food Structure-Netherlands","volume":"49 ","pages":"Article 100548"},"PeriodicalIF":7.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148528069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
