Pomelo peel is a major by-product of pomelo processing, yet its high moisture content and complex structure pose challenges for efficient and high-quality drying. In this study, hot air drying (HAD), near-infrared drying (NID), and microwave drying (MD) were systematically compared in terms of drying kinetics, effective moisture diffusivity, specific energy consumption (SEC), CO₂ emissions, and key quality attributes of pomelo peel. MD achieved the fastest drying, reducing drying time by 87.5% and SEC by 52.7% compared with HAD, whereas NID exhibited superior color retention with the lowest total color difference (ΔE = 9.54) and browning index (BI = 121.30). HAD at 50°C yielded the highest rehydration ratio (287%). Based on the balanced performance of NID in drying efficiency and product quality, ultrasonic pretreatment was further introduced to intensify the NID process. Ultrasonic pretreatment significantly enhanced moisture migration during NID, reducing drying time by up to 28.6% under the investigated conditions. The optimal ultrasound-assisted NID conditions were identified as 300 W ultrasonic power, 5 min treatment time, and 70°C drying temperature. The Modified Page model provided the best fit for drying kinetics across all methods. These results demonstrate that ultrasonic pretreatment effectively strengthens NID by promoting internal mass transfer while preserving product quality, offering a promising strategy for high-value pomelo peel drying.

柚子皮是柚子加工的主要副产品，但其高含水量和复杂的结构对高效、高质量的干燥提出了挑战。本研究系统比较了热风干燥（HAD）、近红外干燥（NID）和微波干燥（MD）对柚子皮的干燥动力学、有效水分扩散系数、比能耗（SEC）、CO2排放和关键品质指标的影响。与HAD相比，MD干燥速度最快，干燥时间缩短87.5%，SEC干燥时间缩短52.7%，而NID的保色性较好，总色差最小（ΔE = 9.54），褐变指数最小（BI = 121.30）。50°C时HAD的再水化率最高（287%）。基于NID在干燥效率和产品质量上的平衡性能，进一步引入超声波预处理来强化NID工艺。超声波预处理显著增强了NID过程中的水分迁移，在所研究的条件下，干燥时间减少了28.6%。超声辅助NID的最佳条件为超声功率300 W，处理时间5 min，干燥温度70℃。在所有方法中，Modified Page模型提供了最适合的干燥动力学。上述结果表明，超声波预处理在保持产品质量的同时，通过促进内部传质，有效地增强了柚皮的NID，为高价值柚皮的干燥提供了一种有前途的策略。

This study demonstrates an efficient and eco-friendly method for extracting flavonoids from Cercis chinensis flowers using ultrasound-assisted deep eutectic solvent (UAE-DES) extraction. Among 17 DES systems screened, L-Proline—Lactic acid (DES-11) achieved the best extraction yield (56.53 mg/g), significantly surpassing that of conventional 60 % ethanol extraction (13.65 mg/g). Through Response Surface Methodology optimization of key parameters (ultrasonic temperature, time, and water content), a maximum flavonoid yield of 95.84 mg/g was obtained under ideal conditions: 32 % water, 36 °C, and 31 min. Scanning electron microscopy (SEM) analysis revealed that DES-11 caused substantial cellular disruption, facilitating flavonoid release. Extraction kinetics followed a pseudo-first-order model, with a calculated apparent activation energy of 20.48 kJ/mol, consistent with a diffusion-controlled mechanism. Additionally, 34 flavonoids were identified for the first time in the DES extract using UPLC-timsTOF-MS. The DES extract exhibited superior antioxidant activity in radical scavenging assays compared to the ethanol extract. Furthermore, DES recovery via macroporous resin yielded an 86.64 % flavonoid recovery rate, and the solvent retained over 84.93 % efficiency after four reuse cycles. These results highlight the UAE-DES method as a sustainable and effective strategy for transforming C. chinensis flowers into high-value natural antioxidants.

研究了超声辅助深共熔溶剂（UAE-DES）提取紫荆花中黄酮类化合物的高效、环保方法。在筛选的17个DES体系中，l -脯氨酸-乳酸（DES-11）的提取率最高（56.53 mg/g），显著超过了传统60%乙醇提取（13.65 mg/g）。通过响应面法优化关键参数（超声温度、超声时间、超声含水量），在32 %水分、36℃、31 min的条件下，黄酮类化合物得率最高可达95.84 mg/g。扫描电镜（SEM）分析显示，DES-11引起大量细胞破坏，促进类黄酮的释放。萃取动力学符合准一阶模型，表观活化能为20.48 kJ/mol，符合扩散控制机理。此外，利用UPLC-timsTOF-MS技术首次从DES提取物中鉴定出34种黄酮类化合物。与乙醇提取物相比，DES提取物在自由基清除实验中表现出更强的抗氧化活性。通过大孔树脂回收DES，黄酮类化合物的回收率为86.64%，重复使用4次后，溶剂的保留率达到84.93%以上。这些结果表明，UAE-DES方法是一种可持续、有效的方法，可以将金盏花转化为高价值的天然抗氧化剂。

Ultrasound processing offers a sustainable and non-chemical strategy for controlling molecular organization in soft materials. In this work, we show that ultrasonication can reorganize chitosan-silk blends into ordered microphase architectures similar to classical AB block copolymers without any chemical synthesis providing a novel strategy to control nanoscale morphology and enhance material functionality. Composite films were prepared using Bombyx mori silk fibroin and chitosan spanning low, medium, and high molecular weight ranges, followed by ultrasound treatment under optimized time and power conditions. The resulting materials were examined using scanning electron microscopy (SEM) to resolve microphase domains, Fourier-transform infrared spectroscopy (FTIR) to probe molecular interactions, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) to assess thermal behaviors, and X-ray diffraction (XRD) to analyze crystalline organization. Ultrasound treatment induced nanoscale structural ordering, enhanced intermolecular hydrogen bonding, and increased β-sheet formation in silk proteins, giving rise to distinct spherical, insular, and lamellar microdomains. These ultrasound-mediated structural transformations produced substantial improvements in thermal stability, mechanical performance, hydrophilicity, and morphological uniformity compared with untreated films. This study provides the first direct evidence that ultrasonic energy alone can drive biopolymer blends into ordered microphase patterns traditionally associated with block-copolymer chemistry. These findings position ultrasonication as a simple, green, and scalable platform for designing biomaterials with tunable hierarchical structures and multifunctional properties suitable for advanced biomedical and sustainable applications.

Lactobacillus-fermented soymilk can improve texture and flavor through microbial metabolism. The application of processing techniques that preserve the nutritional value, quality, and bioactive properties of fermented soymilk without compromising their integrity is of great significance. Ultrasound can promote the decomposition of proteins in soymilk by disrupting their structure, and also has a cell wall-breaking effect on the fermentation strains in soymilk, causing the beneficial components of the bacteria to be released into the soymilk, thereby changing the characteristics and material composition of the fermented soymilk and increasing the content of nutrients and the stability of the soymilk. This study revealed that ultrasonic treatment (150 W, 20 min) significantly improved the texture and stability of Lactobacillus gasseri JM1- fermented soymilk, reduced the viscosity of the fermented soymilk (1918.80 ± 112.33 cP), and increased the water-holding capacity of the soymilk (97.12%). Moreover, ultrasonic treatment (150 W, 20 min) also led to an increase in active aglycone isoflavones such as daidzein (17.32 μg/ml) and genistein (24.48 μg/ml) in the fermented soymilk. Metabolomics and proteomics were used to establish a metabolic network of metabolites, revealing the changes in the main metabolic substances in the fermented soymilk before and after ultrasonic treatment. KEGG analysis exhibited that the carbohydrate metabolism and amino acid metabolism pathways of the metabolites in the ultrasonically treated fermented soymilk were obviously up-regulated. This study provides a theoretical basis for the innovation, flavor extension and quality improvement of fermented soymilk products.

乳酸菌发酵豆浆可以通过微生物代谢改善质构和风味。采用既能保持发酵豆浆的营养价值、质量和生物活性又不损害其完整性的加工技术具有重要意义。超声波可以通过破坏豆浆中蛋白质的结构来促进其分解，同时对豆浆中的发酵菌种也有破壁作用，使细菌的有益成分释放到豆浆中，从而改变发酵豆浆的特性和物质组成，提高豆浆的营养成分含量和稳定性。结果表明，超声处理（150 W, 20 min）显著改善了发酵豆浆的质地和稳定性，降低了发酵豆浆的粘度（1918.80 ± 112.33 cP），提高了豆浆的保水能力（97.12%）。此外，超声波处理（150 W, 20 min）也导致发酵豆浆中大豆苷元（17.32 μg/ml）和染料木素（24.48 μg/ml）等活性苷元异黄酮含量增加。利用代谢组学和蛋白质组学建立代谢物的代谢网络，揭示超声处理前后发酵豆浆中主要代谢物质的变化。KEGG分析表明，超声处理发酵豆浆代谢产物的碳水化合物代谢和氨基酸代谢途径明显上调。本研究为豆浆发酵产品的创新、风味延伸和品质提升提供了理论依据。

Beetroot leaf, typically discarded as agricultural waste, is a promising source of plant-based proteins. With growing interest in sustainable and eco-friendly food production, extracting high-quality protein from such by-products supports a circular economy. This study optimized ultrasound-assisted alkaline extraction (UAAE) using a Box-Behnken design to maximize protein yield and content from beetroot leaves. The combination of ultrasound and alkaline treatment has been shown to enhance extraction efficiency and protein techno-functionality in comparison with conventional alkaline method (CAE). Optimal UAAE conditions (40 min, pH 11, 27.2 °C) yielded a protein content of 73.4% with a 10% extraction yield. Fourier transform infrared spectroscopy analysis confirmed that the secondary structure of beetroot leaf protein (BLP) obtained by UAAE remained intact, while microscopic analysis revealed a more compact globular morphology. Additionally, BLP obtained by UAAE showed better heat resistance and less aggregations, supported by a higher absolute zeta potential value (−31.06 mV, compared to −24.03 mV for BLP obtained by CAE). Both BLP obtained by UAAE and CAE displayed proportional increases in foaming capacity and stability with higher protein concentrations. UAAE led to improved digestibility of the BLP compared to legume protein isolates such as soy and pea protein. These findings highlight UAAE as an efficient method to produce high-quality protein from beetroot leaves, suitable for vegan foods, supplements, and pharmaceuticals.

甜菜根叶，通常作为农业废弃物丢弃，是植物性蛋白质的一个有前途的来源。随着人们对可持续和环保食品生产的兴趣日益浓厚，从这些副产品中提取高质量的蛋白质支持了循环经济。本研究采用Box-Behnken设计优化超声辅助碱性提取（UAAE），以最大限度地提高甜菜根叶的蛋白质产量和含量。与传统的碱法（CAE）相比，超声和碱法联合处理可以提高提取效率和蛋白质技术功能。最佳UAAE条件（40 min, pH 11, 27.2 °C），蛋白含量为73.4%，提取率为10%。傅里叶变换红外光谱分析证实，通过UAAE获得的甜菜根叶蛋白（BLP）二级结构保持完整，而显微镜分析显示其具有更紧凑的球状形态。此外，UAAE获得的BLP具有更好的耐热性和较少的聚集，这得益于更高的绝对zeta电位值（- 31.06 mV，而CAE获得的BLP为- 24.03 mV）。UAAE和CAE制备的BLP均显示出随着蛋白质浓度的增加，泡沫容量和稳定性呈比例增加。与豆科分离蛋白（如大豆和豌豆蛋白）相比，UAAE提高了BLP的消化率。这些发现强调了UAAE是一种从甜菜根叶中生产高质量蛋白质的有效方法，适用于素食食品、补充剂和药品。

The efficient treatment of aged oily sludge, a challenging by-product of the petroleum industry, is crucial for resource recovery and environmental protection. Conventional methods often suffer from limited oil recovery efficiency. This study proposes a novel application of jet cavitation technology to disintegrate aged oily sludge, aiming to enhance oil recovery and reduce petroleum hydrocarbon content. The mechanism of disintegration involves both mechanical and chemical effects: the mechanical forces destroy hydrogen bonds to facilitate oil phase desorption, while cavitation-induced chemical bond rupture and free radical oxidation degrade long-chain hydrocarbons into short-chain compounds. The physicochemical properties (oil components, functional groups, petroleum hydrocarbons) of the sludge were comprehensively analyzed before and after treatment using multi-scale characterization techniques, including laser particle sizing, contact angle and Zeta potential measurements, combined with Thin Layer Chromatography-Flame Ionization Detection (TLC-FID), Fourier Transform Infrared Spectroscopy (FT-IR), and Gas Chromatography-Mass Spectrometry (GC–MS). Under optimized conditions (inlet pressure of 14.9 MPa, jet water temperature of 40°C, sludge concentration of 21.16%, hydraulic retention time of 5.98 s, and sludge temperature of 50°C), a maximum oil recovery rate of 84.95% was achieved. This result is significantly superior to the efficiency obtained via ultrasonic cavitation treatment, demonstrating the notable advantage and potential of the jet cavitation method for the effective treatment of aged oily sludge.

老化含油污泥是石油工业中具有挑战性的副产品，其有效处理对资源回收和环境保护至关重要。常规方法的采收率往往有限。本研究提出了一种新的应用射流空化技术来分解老化的含油污泥，以提高石油采收率和降低石油烃含量。分解机理包括机械和化学两方面的作用：机械力破坏氢键促进油相脱附，而空化引起化学键断裂和自由基氧化使长链烃降解为短链化合物。采用多尺度表征技术，包括激光粒度、接触角和Zeta电位测量，结合薄层色谱-火焰离子化检测（TLC-FID）、傅里叶变换红外光谱（FT-IR）和气相色谱-质谱（GC-MS），综合分析处理前后污泥的理化性质（油组分、官能团、石油烃）。在进口压力14.9 MPa、喷射水温40℃、污泥浓度21.16%、水力滞留时间5.98 s、污泥温度50℃的优化条件下，最大采收率为84.95%。这一结果明显优于超声空化处理的效果，说明了射流空化法有效处理老化含油污泥的显著优势和潜力。

Emerging extraction methods, such as enzyme-assisted extraction (EAE) and ultrasound-assisted extraction (UAE), are considered safer and more sustainable alternatives to conventional techniques, due to their reduced solvent usage. Nevertheless, their application remains limited due to their low efficiency and sensitivity to environmental conditions. To overcome these drawbacks, ultrasound-assisted enzymatic extraction (UAEE) has been proposed as an alternative synergistic approach to improve biomass disruption. In this study, the effect of ultrasound on the susceptibility of pectic substrates to enzymatic degradation was evaluated using both purified pectin and pectin-rich complex matrices (grapefruit peels and apple pomace). The extent of enzymatic degradation was assessed by monitoring the release of reducing sugars, while microscopic evaluation of the cell microstructure, the total phenolic release (TPC) and metal element release were quantified to support the findings.

Results indicate that ultrasonic pre- and post-treatments had no significant impact on pectin hydrolysis. In contrast, when ultrasound was applied during the enzymatic reaction, the extent of hydrolysis increased, but only in the case of the complex matrices, indicating a synergistic effect. The increased release of calcium and potassium ions suggested that ultrasound induced an enzymatic cofactor release from biomass, contributing to improved enzyme activity. Similar degradation of the cell microstructure was observed in the case of ultrasonic post treatment, although without improved hydrolysis of cell-wall pectin. This implies that prior enzymatic action weakened the matrix, making it more fragile. This is the first study to investigate the impact of plant matrix structure on the synergistic effect of the ultrasound-enzyme combination.

新兴的提取方法，如酶辅助提取（EAE）和超声辅助提取（UAE），被认为是传统技术更安全、更可持续的替代品，因为它们减少了溶剂的使用。然而，由于其效率低和对环境条件的敏感性，其应用仍然受到限制。为了克服这些缺点，超声辅助酶提取（UAEE）被提出作为一种替代的协同方法来改善生物质破坏。本研究利用纯化果胶和富含果胶的复合基质（葡萄柚皮和苹果渣）对超声波对果胶底物酶降解敏感性的影响进行了评价。通过监测还原糖的释放来评估酶降解的程度，同时对细胞微观结构、总酚释放（TPC）和金属元素释放进行了量化评估，以支持研究结果。结果表明，超声前后处理对果胶水解无显著影响。相比之下，在酶促反应中应用超声波时，水解程度增加，但仅在复杂基质的情况下，表明协同作用。钙离子和钾离子的释放增加表明，超声波诱导了生物质的酶辅因子释放，有助于提高酶的活性。在超声波后处理的情况下，观察到类似的细胞微观结构降解，尽管没有改善细胞壁果胶的水解。这意味着先前的酶作用削弱了基质，使其更脆弱。这是首次研究植物基质结构对超声-酶联合协同效应的影响。

To investigate the effect of ultrasound on the cooking time of Coix seed, this study compared changes in the pasting properties of Coix seed under different ultrasonic times (0, 10, 20, and 30 min), and clarified the mechanism of ultrasound improving the cooking properties of Coix seed by analyzing the changes in starch structure and physicochemical properties. The results showed that cooking time decreased significantly as the ultrasonic time increased, with a 35% reduction in cooking time after 30 min of ultrasonic treatment compared to untreated Coix seeds. Ultrasound treatment induced the formation of visible pores on Coix seed starch surfaces. The significant increase in granule size was attributed to granule swelling and physical agglomeration caused by structural loosening. Crystallinity decreased from 27.56% to 20.41%, and the short-range order (R_1047/1022) dropped from 2.074 to 1.535. Thermal analysis revealed a reduction in gelatinization enthalpy (ΔH) from 14.82 to 13.47 J/g and a lower energy barrier for gelatinization. Regarding physicochemical properties, ultrasonically treated Coix seed starch exhibited increased solubility and swelling power, while demonstrating decreased peak viscosity and final viscosity. Furthermore, rheological measurements showed that the storage modulus (G′) and loss modulus (G″) at 10 Hz decreased by approximately 34%. In conclusion, ultrasonic treatment significantly shortened the cooking time of Coix seeds, demonstrating its potential as an effective strategy for pre-gelatinization processing.

为了研究超声对薏苡仁蒸煮时间的影响，本研究比较了不同超声时间（0、10、20、30 min）下薏苡仁糊化性能的变化，并通过分析超声对薏苡仁淀粉结构和理化性质的变化，阐明了超声改善薏苡仁蒸煮性能的机理。结果表明，随着超声处理时间的增加，薏苡仁的蒸煮时间显著缩短，超声处理30 min后，薏苡仁蒸煮时间比未处理的薏苡仁蒸煮时间缩短35%。超声处理诱导薏苡仁淀粉表面形成可见孔隙。颗粒尺寸的显著增加是由于结构松动引起的颗粒膨胀和物理团聚。结晶度由27.56%降至20.41%，近程序（R1047/1022）由2.074降至1.535。热分析表明，糊化焓（ΔH）从14.82降至13.47 J/g，糊化能垒降低。在理化性质方面，超声处理后的薏苡仁淀粉溶解度和溶胀力增加，峰值粘度和最终粘度降低。此外，流变学测量表明，在10 Hz下，存储模量（G′）和损耗模量（G″）下降了约34%。综上所述，超声处理显著缩短了薏苡仁的蒸煮时间，显示了其作为预糊化加工的有效策略的潜力。

Sonochemistry is an innovative and sustainable method among the emerging non-thermal technologies for agrochemical removal, food processing, and preservation. The study aimed to investigate the effects of probe-type ultrasound (PU) on the residual degradation mechanisms of carbendazim (CBZ) fungicides, potential reduction pathways, and toxicity assessment. The results showed that CBZ fungicide residues were significantly reduced (p < 0.05) by up to 79.20 % as the PU power level increased. The GC–MS analysis identified six degradation products of CBZ fungicides, including 3–2-Hydroxyphenyl-1,2,4-triazol-5-amine, 2-aminobenzimidazole, hexahydropyridine, 3-methoxy-benzaldehyde oxime,1,4-dimethylpyrazole, and 1-alanine-ethylamide. In addition, the toxicity of CBZ was evaluated against Aspergillus Niger (AN) using colony counts as an indicator of fungal growth, inhibition ratio, and survival rate. The results revealed that the lower power level showed a strong inhibition ratio of up to 73.30 % compared to the highest power level, which was 28.50 %. Increasing the power level significantly increased the AN’s survival rate from 25.50 % to 75.60 %. The current study’s results suggest that sonication has significant potential to degrade agrochemicals by generating hydroxyl radicals. The current study provides new insights into the sonication-assisted degradation of CZB by describing its degradation mechanism and toxicity assessment. Unlike literature-reported studies, our results proposed a detailed degradation pathway, degradation byproducts, and a toxicity assessment of degradation intermediates, providing both the degradation behavior and the effectiveness of sonication treatment in reducing agrochemical residues.

声化学是一种创新和可持续的方法，在新兴的非热技术中用于农业化学品去除，食品加工和保存。本研究旨在探讨探针型超声（PU）对多菌灵（CBZ）杀菌剂残留降解机制、可能的还原途径及毒性评价的影响。结果表明，随着PU功率的增加，CBZ杀菌剂残留量显著降低（p < 0.05），降幅达79.20%。GC-MS分析鉴定出6种CBZ杀菌剂的降解产物，包括3- 2-羟基苯基-1,2,4-三唑-5-胺、2-氨基苯并咪唑、六氢吡啶、3-甲氧基-苯甲醛肟、1,4-二甲基吡唑和1-丙氨酸-乙胺。此外，以菌落计数作为真菌生长、抑制率和存活率的指标，评价了CBZ对黑曲霉（Aspergillus Niger， AN）的毒性。结果表明，较低功率下的抑制率为73.30%，较高功率下的抑制率为28.50%。随着功率水平的提高，AN的存活率由25.50%显著提高到75.60%。目前的研究结果表明，超声波通过产生羟基自由基来降解农用化学品具有重要的潜力。本研究通过阐述CZB的降解机制和毒性评价，为超声辅助降解CZB提供了新的思路。与文献报道的研究不同，我们的研究结果提出了详细的降解途径、降解副产物和降解中间体的毒性评估，提供了降解行为和超声处理在减少农用化学品残留方面的有效性。
