Magnetic induction electric field (MIEF) represents a novel physical technology, yet its application in LEW modification remains unreported. In this study, LEW were treated at excitation voltages of 450–650 V. The effects of MIEF on EWP structure, surface properties, apparent viscosity, and foaming characteristics were investigated. The results demonstrated that MIEF treatment significantly increased the surface hydrophobicity and zeta potential of EWPs, while reducing the particle size from 600 nm to 219 nm at 600 V excitation voltage. Scanning electron microscopy corroborated these findings, revealing pore structure formation. Concurrently, enhanced intermolecular interactions promoted dynamically crosslinked mesh structure formation, thus increasing apparent viscosity. Accordingly, MIEF treatment significantly improved both the foaming ability and foam stability of EWP, with a 22.18 % increase in foaming ability and a 26.30 % increase in foam stability<strong>.</strong> In conclusion, MIEF induces moderate denaturation of EWPs, achieving a balance between interfacial properties enhancement and avoidance of protein aggregation. These results establish a theoretical and practical foundation for applying MIEF technology to EWP modification in the food industry, offering potential to advance innovation in food processing.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"170 ","pages":"Article 111736"},"PeriodicalIF":11.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144623720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this challenge, we developed two rutin-caseinate composites (RCC1 and RCC2) as delivery vehicles for incorporation into functional foods/beverages. While both systems deliver rutin at high concentration, they differ in terms of methodology, loading capacity, and applications. The gastrointestinal stability, bioaccessibility, and antioxidant potential of these delivery systems, both alone and incorporated into a functional dairy beverage (flavoured milk), were assessed. We also examined the cytotoxicity, absorption, and intestinal barrier integrity of rutin using an intestinal epithelial cell model. The bioaccessibility of rutin from RCC1 and RCC2 was found to be 63 % and 45 %, respectively, compared to untreated rutin (UR), which was undetectable due to precipitation. Additionally, RCC2 exhibited superior intestinal barrier integrity with a trans-epithelial electrical resistance (TEER) value of 1655 Ω/cm² for 24 h , outperforming both RCC1 (1384 Ω/cm²) and UR (915 Ω/cm²). Intracellular antioxidant activity was significantly higher for both composites in terms of lower relative fluorescent units (RFU); 44 RFU for RCC1 and 42 RFU for RCC2, compared to 63 RFU for UR, demonstrating their enhanced protective effects. Caco-2 cell viability of the composite samples was higher, with no cytotoxicity observed compared to UR, confirming their safety. When incorporated into milk, both systems improved rutin bioaccessibility, with RCC1 showing a stronger antioxidant response (87 RFU) than RCC2 (100 RFU) and untreated rutin (140 RFU) during extended incubation. These findings suggest that both RCC1 and RCC2 are stable, soluble, and safe for physiological systems. Their incorporation into dairy matrices enhances rutin bioaccessibility and antioxidant potential, making them a promising approach for functional foods development.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"170 ","pages":"Article 111735"},"PeriodicalIF":11.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An innovative approach was proposed by using fish skin protein (FSP) from <em>Channa argus</em> as a natural carrier to promote the self-assembly of rosmarinic acid (RA) and curcumin (CUR) into stable nanospheres (FSP/CUR/RA) through non-covalent interactions such as hydrogen bonds, π-alkyl/π-anion interactions, and electrostatic interactions in this study. Compared with binary systems, the self-assembled FSP/CUR/RA ternary nanospheres exhibited significant advantages in colloidal stability and functionality: the optimized RA6 nanospheres have the smallest particle size (508 ± 19.30 nm), the highest ζ-potential (13.04 mV), and excellent antioxidant activity (ABTS⁺ scavenging rate of 87.91 % at 20 μL), effectively overcoming the limitations of poor solubility and instability of CUR and RA. Upon incorporating the nanospheres into the active film, its overall performance was significantly enhanced. Specifically: Barrier properties were improved, with the water vapor transmission rate reduced to 4.06 × 10⁻¹³ g m⁻¹·Pa⁻¹·s⁻¹, representing a 27.6 % decrease compared to the pure FSP film. Mechanical properties were optimized due to RA's effective inhibition of CUR aggregation, achieving a well-balanced tensile strength (TS) and elongation at break (EAB). The film demonstrated outstanding antioxidant capacity, with a free radical scavenging rate of 86.39 %, significantly higher than the control groups. Multifunctional characteristics were evident, including ultraviolet shielding capability, controlled release of CUR/RA, and complete biocompatibility (cell viability 100 %).

In this context, this study aimed to produce and characterize flours derived from breadfruit (BF) pulp and peel in terms of their physical, techno-functional, pasting and rheological properties. Banana flour was used as a reference for comparison purpose. BF flours formed heat-stable gels at a 4 % concentration, double the threshold required for banana flour, with higher water absorption capacity (+68 %), swelling power (+75 %), and five-fold lower solubility than banana flour. BF-pulp flour demonstrated 10 % higher emulsifying activity and 60 % higher emulsion stability. Additionally, it showed a higher pasting temperature, increased final viscosity (+24 %), and substantially lower breakdown viscosity (−75 %) compared to banana. All gels exhibited pseudoplastic flow behavior, with BF-pulp presenting the highest consistency index and thixotropy. Dynamic oscillatory tests revealed superior viscoelastic properties in BF-gels, with storage and loss moduli exceeding those of banana gel at equivalent concentrations. Retrogradation kinetics showed faster amylopectin recrystallization in BF gels, in particular those from BF-pulp flour, compared to banana gel, suggesting an earlier achievement of structural stability during storage. In contrast, banana gels exhibited a higher leveling-off retrogradation enthalpy, reflecting a firmer and more stable texture over long-term storage. These findings position BF-pulp flour as a high-performance hydrocolloid, offering enhanced gel strength and emulsion stability, suitable for gluten-free sauces or bakery fillings. Meanwhile, the lower viscosity and unique shear rheology of BF-peel flour may benefit low-viscosity applications.

The shear rheology results showed that XG with the higher Mw showed higher [η] and better shear thinning behaviors, indicating easier swallowing.
