The structural changes induced by pulsed electric field (PEF) treatment can make low-porosity products more susceptible to the effects of ultrasound during drying. This study aimed to investigate the influence of PEF treatment on the structure of low-porosity products, such as butternut squash, and to evaluate its effect on ultrasonic-assisted drying. PEF pretreatment altered the physicochemical and microstructural properties of butternut squash. Thus, the higher the energy input, the higher the cell disintegration rate, the lower the shearing force and the lower the water holding capacity. For the same energy input applied, no influence was observed from the different combinations of pulse number and electric field intensity used. The microstructural analysis also showed greater effects with increasing intensity of PEF treatments. All these changes affected the subsequent drying, increasing the drying rate of conventional drying. Moreover, PEF pretreatment enhanced the ultrasound effects when applied during drying, reducing drying time by up to 47% when moderate PEF intensity was used. Therefore, PEF pretreatment under the appropriate conditions could make ultrasound-assisted drying of low-porosity products, such as butternut squash, more feasible.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"112 ","pages":"Article 107155"},"PeriodicalIF":8.7,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the effects of ultrasonic pretreatment on the fibrillation kinetics, physicochemical properties, and functional aspects of soy protein isolate amyloid fibrils (SPF). Firstly, soy protein isolates (SPI) were subjected to ultrasonic pretreatment by regulating time and power under neutral conditions. Subsequently, the pretreated SPI was converted into SPF through acidic heating. The results indicated that ultrasonic pretreatment significantly improved surface hydrophobicity and solubility of SPI through ultrasound’s cavitation and thermal effects. Thioflavin T fluorescence assay revealed SPF40 (450 W, 40 min) had the fastest growth rate, 104.23 % higher than SPF0 (without ultrasonic pretreatment), while SPF10 (450 W, 10 min) had the highest fibril yield, 20.97 % higher than SPF0. Physicochemical analysis showed that ultrasonic pretreatment accelerated the formation of SPF from SPI by exposing the surface hydrophobic groups, lowering the zeta potential, breaking down original fibrils into shorter fibrils, and altering the secondary structure from α-helices into β-sheets. Morphological examination by transmission electron microscopy exhibited a higher maturation state, showing more rigid and straight fibrils structure in SPF10 compared to SPF0. Functionally, SPF with ultrasonic pretreatment had higher emulsifying activity than SPI and SPF0. Rheological analysis further confirmed SPF emulsions’ better mechanical strength over SPI emulsions. Overall, this study demonstrates that ultrasonic pretreatment is an effective way to enhance the formation and properties of SPF, which can be further applied to developing advanced protein products and novel functional food systems.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"112 ","pages":"Article 107157"},"PeriodicalIF":8.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142680105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The remaining fiber-rich fraction (residue) was further utilized. Water content in biscuit formulation was replaced by the extract, and the fiber-rich fraction was substituted at three substitution levels; 2.5 %, 5 % and 7.5 %.

TPC was higher in biscuits than dough, with the highest values of 0.46 mg gallic acid equivalents (GAE)/g and 2.26 mg GAE/g in dough and biscuit, respectively. Fiber and moisture contents in biscuits increased while protein content decreased with fortification. Consumers showed moderate acceptance of fortified biscuits with overall acceptability comparable with the control biscuits.

Compared with the traditional extraction process, ultrasound has been used to enhance the extraction efficiency of various plant-based proteins. To reveal the mechanism of ultrasound-enhanced extraction of proteins, adaptive neuro-fuzzy inference system (ANFIS) algorithm and numerical simulation based on Fick’s law were applied to illustrate the mass transfer behavior of millet proteins under different ultrasonic conditions including solid–liquid ratios (S/L ratios), pH and acoustic energy density levels (AED). The results showed that AED dominated the changes in effective diffusion coefficient (<span><math><mrow><msub><mi>D</mi><mi>e</mi></msub></mrow></math></span>), showing a positive correlation relationship (<em>p</em> &lt; 0.05).

Meanwhile, the ANFIS model successfully predicted protein yields across all investigated parameters, achieving a coefficient of determination (R²) greater than 0.97. This model also elucidated the interactions among four critical factors, among which pH and S/L ratios were the main factors affecting protein yield. Concerning the ultrasonic cavitation bubble dynamics, the bubble collapse efficiency enhanced with an increase in AED, and therefore high AED ultrasound can significantly enhance the cavitation effect. Additionally, the results of the yields and physical properties of millet protein also indicated that in contrast with the traditional extraction methods, the ultrasound impactfully improved extraction yield (by 165%), and combined with pH condition, it decreased the protein particle size (from 813.55 nm to 299.30 nm) without altering the molecular weight distribution.
