In this study, extrinsic proteins (OP) from soybean oleosomes were extracted under controlled alkaline-ultrasonic treatment (0-400 W) to elucidate how ultrasound-mediated protein remodeling governs interfacial adsorption kinetics, high-internal-phase emulsion (HIPE) formation, rheological behavior, and probiotic protection. Alkaline-ultrasonic treatment from 0 to 300 W significantly increased the protein recovery from 40.15% to 58.84%, solubility from 74.10% to 87.61%, and zeta potential from -8.81 to -13.31 mV, while reduced the particle size from 651 to 389 nm. Spectroscopic analyses revealed controlled protein remodeling characterized by increased exposure of hydrophobic and aromatic residues, reduced α-helix content from 22.95% to 15.03%, and increased β-sheet structures from 34.16% to 42.14%. Ultrasonic treatment (300 W) effectively improved the protein diffusion rate (0.106 to 0.182 mNm^-1s^-0.5) and penetration rate (3.971 × 10^-4 to 4.682 × 10^-4 s^-1) at the oil-water interface, indicating the formation of strengthened interfacial protein films. HIPEs stabilized by OP-300 revealed the smallest droplet size, intensified droplet-droplet interactions, superior viscoelastic properties, and excellent storage stability. LAOS analysis further confirmed that HIPEs prepared with OP-200 and OP-300 maintained structural integrity under large deformation amplitudes ≤100%, compared to the untreated sample ≤10%, indicating the formation of stronger and more cohesive gel networks. Moreover, encapsulated Lactobacillus reuteri showed improved survival rate during simulated digestion, increasing viable cell counts from 4.12 × 10⁷ to 7.21 × 10⁷ CFU/mL.

Compared with soaking at ambient temperature, ultrasound-assisted treatment increased gypsum removal 8.5-fold with potassium carbonate and 56-fold with tetrasodium EDTA.

Potassium carbonate converts gypsum layer by layer under silent conditions, whereas ultrasound produced deep cavities beyond the surface layer, consistent with localized cavitation-induced penetration.

These changes directly affect the sensory attributes that shape consumer perceptions and acceptance of novel foods. This review examines the mechanistic relationship between US food processing and the consumer sensory-acceptance barrier, drawing on evidence from sonochemistry, behavioral economics, sensory science, food policy, and digital marketing. We stated that US-induced modifications in flavor (through modulation of Maillard reaction precursors, volatile compound generation, and lipid oxidation control), texture (through starch gelatinization, emulsion stabilization, and myofibrillar disruption), aroma (through controlled release of encapsulated volatile compounds), and color (through Maillard browning and pigment stability) potentially contribute to consumer acceptance by affecting sensory attributes. However, these relationships should be considered as proposed pathways rather than experimentally validated causal mechanisms, as direct consumer acceptance studies remain limited. Specifically, US-modified flavor and texture profiles of PBMAs, microalgae ingredients, and insect protein powders address the most consistently cited sensory barriers to consumer trial and repeat purchase. The review further combines cross-domain moderators, cultural disgust, food neophobia, behavioral nudges, labeling framing, digital and social media influence, and pricing that operate at higher cognitive and policy levels, demonstrating how US sensory improvements must be coupled with consumer-centered communication strategies to translate physicochemical gains into marketplace acceptance. A comparative analysis of existing studies indicates a persistent attitude-behavior gap, suggesting that US-optimized sensory quality alone does not fully determine consumer acceptance.</p>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"134 ","pages":"108117"},"PeriodicalIF":10.2,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149223129","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}

However, the growth phase-dependent metabolic responses of LAB to low-frequency ultrasonication remain poorly understood. In this study, low-frequency ultrasonication (83.6 and 119.17 W/L) was applied during the lag, logarithmic, and stationary phases of Lactobacillus acidophilus LA137 fermentation in Citrus aurantium L. juice. Microbial growth, physicochemical properties, β-glucosidase activity, total phenolic and flavonoid contents, and antioxidant capacity were evaluated in this study. Ultrasonication applied during the logarithmic and stationary phases exerted greater effects on microbial metabolism and functional quality than treatment during the lag phase. Among all treatments, ultrasonication at 119.17 W/L during the logarithmic phase (LU4) and 83.6 W/L during the stationary phase (LU5) showed superior enhancement of β-glucosidase activity, phenolic/flavonoid accumulation, and antioxidant capacity. Integrated untargeted metabolomics revealed distinct metabolic responses between LU4 and LU5. LU4 preferentially promoted phenylpropanoid and flavonoid metabolism, resulting in the accumulation of antioxidant-related metabolites, including gallic acid, taxifolin, and 7-galloylcatechin. In contrast, LU5 mainly enhanced amino acid and organic acid metabolism, leading to increased levels of lactic acid, γ-aminobutyric acid, alanine, and serine.

To address this issue and reveal the underlying mechanisms, a rotational ultrasonic atomization platform was developed. The effects of ultrasonic power, liquid viscosity, horn geometry, rotation speed, and initial momentum on atomization behavior were investigated using high-speed imaging. For low-viscosity liquids, increasing ultrasonic power elevated the Weber number, widened the spray angle from 63 degrees to 142 degrees, and shortened the atomization incubation period from 10.86 s to 8.15 s. For high-viscosity liquids, viscous damping suppressed the capillary wave pathway, making cavitation the dominant mechanism. Driven by the secondary Bjerknes force, cavitation bubbles bridged into branched, neural-network-like clusters. Their collective collapse overcame the viscous dissipation barrier, providing experimental validation for Boguslavskii’s hypothesis. A critical rotation threshold of 60 revolutions per minute was identified. Below this threshold, acoustic pinning confined the liquid on the horn end-face; above it, centrifugal force forcibly thinned the liquid film, triggering atomization. Furthermore, horn geometry determined the atomization onset location, while increased initial momentum accelerated initiation. Experiments on Sn-58Bi melt verified that coupling optimized horn geometry with a centrifugal force field effectively overcomes the surface energy barrier. Based on these findings, a six-stage atomization model is proposed. The capillary wave mechanism primarily achieves initial film thinning by stripping large droplets, while cavitation dominates fine fragmentation.

The effects of ultrasonic parameters (probe position, power and mode) on the lateral seepage rate and leaching efficiency were investigated. Influence of thermal effect and ultrasonic effect on leaching was distinguished. The results indicate that applying ultrasound in the middle position of the ore body achieves the higher leaching efficiency and lateral seepage rate compared to other positions.
