However, its high molecular weight and viscosity limit its industrial applications. To enhance its functional and structural properties, oat 1, 4-β-D-glucan was modified using ultrasonication (US) and ozonation (OZ), and its functional, structural, thermal, and rheological properties were characterized. The yield and recovery of 1, 4-β-D-glucan were 4.74 % and 81.6 %, respectively. Molecular weight decreased from 1450 × 10³ Da (native) to 52 × 10³ Da (OZ-II). Hydrodynamic particle size reduced from 2510.8 nm (native) to 156.3 nm (OZ-II), with a polydispersity index and zeta potential of −10.8 mV indicating enhanced uniformity and stability. FE-SEM showed structural disruption in US-treated samples and porosity in OZ-treated samples. DSC analysis indicated increased thermal stability in OZ-II, with the highest onset temperature (29.71 °C) and lowest enthalpy change (107.52 J/g). The frequency sweep and shear test showed that all samples exhibited shear-thinning property and lowest viscosity values were observed for OZ-II. FTIR spectra confirmed structural modifications, with increased peaks at 1720 cm⁻¹ (C<img>O stretching) in OZ-treated samples, indicating oxidation. Additionally, X-ray diffraction analysis revealed a reduction in crystallinity index from 32.2 % (native) to 29.4 % (OZ-II), attributed to disruption of the crystalline regions by ozone treatment. These findings demonstrate that US and OZ modifications significantly enhance the functionality and processing suitability of 1, 4-β-D-glucan, providing valuable insights for its industrial application.</div></div>","PeriodicalId":329,"journal":{"name":"Innovative Food Science & Emerging Technologies","volume":"102 ","pages":"Article 103977"},"PeriodicalIF":6.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520263","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}

XBS-WF, valued for its rich color and high nutritional content, poses challenges in dough handling and Mantou production due to its unique characteristics. In this study, samples were treated under CP conditions at 40 V and 0.9 A for 2, 4 and 6 min, with untreated samples serving as a control, and it was found that the CP treatment improved key quality parameters of the dough, including starch granule morphology, viscosity, pasting behavior, water absorption, and stability. These changes contributed to improvements in dough color, aroma, and overall handling properties. However, prolonged CP exposure led to undesirable effects, such as starch granule aggregation and changes in dough microstructure, which increased hardness and elasticity but reduced adhesion and chewiness. CP-treated XBS-WF dough showed enhanced sensory attributes, particularly in taste, flavor, and texture. For the Mantou, CP treatment resulted in improved color, texture, fluffiness, elasticity, and overall mouthfeel, aligning well with consumer preferences. Low-field nuclear magnetic resonance analysis revealed a redistribution of water within the dough, likely due to the reinforcement of the gluten network, which contributed to improved moisture retention and Mantou quality. Sensory evaluations further confirmed the superiority of CP-treated Mantous in terms of appearance, porosity, structure, and resilience, leading to higher consumer acceptance. These results suggest CP as a promising method to enhance XBS-WF processing quality with potential for industrial use.</div></div>","PeriodicalId":329,"journal":{"name":"Innovative Food Science & Emerging Technologies","volume":"102 ","pages":"Article 103957"},"PeriodicalIF":6.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453320","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}

The significant differences in HU values between the untreated group and the treated eggs began to be observed from the day-10. The significant differences were found in the HU both in the untreated group (47.95) and in the eggs treated with ultrasonication (55.56), thermosonication (63.64), and pasteurization (73.28), with the highest HU value found in the pasteurized eggs at day-30. It was observed that thermosonication treatments maintained higher YI values compared to the untreated group, with significant differences between the values. The pH of the albumen and yolk at all groups increased in the highest value with control (albumen 9.44 - yolk 6.44), ultrasonication (albumen 9.35 - yolk 6.34), thermosonication (albumen 9.37 - yolk 6.41), and pasteurization (albumen 9,40 - yolk 6.35). The albumen dry matter values tended to increase in all groups during the storage, with the lowest dry matter results observed in the ultrasonicated samples. The relative foam capacity (RWC) value of the eggs treated with ultrasonication (796) was higher than those of the control (626), thermosonication (735), and pasteurization (680) groups. It was highlighted that thermal treatment led to a decrease in the RWC values at day-30. The lowest shell strength values were observed in the thermosonication samples due to both the cavitation mechanism and heat. This study demonstrated that thermosonication process is efficacious in maintaining the quality attributes of the fresh shell eggs. It was found that the combination of ultrasound with heat particularly improved quality characteristics such as HU and YI. Thermosonication applications could be an important and effective alternative for enhancing the internal-quality attributes and increasing the storage stability of eggs.</div></div>","PeriodicalId":329,"journal":{"name":"Innovative Food Science & Emerging Technologies","volume":"102 ","pages":"Article 103969"},"PeriodicalIF":6.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453321","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}
