This study aimed to evaluate the characteristics of sorption and thermodynamic properties of different wall materials assembled from composite-based of modified pinhão (Araucaria angustifolia) starch by microwave (MS) combined with polydextrose (PD), partially hydrolyzed guar gum (PHGG), or whey protein isolate (WPI) and dried by spray-drying (SD) or freeze-drying (FD). The rheological properties of the dispersions showed that they exhibited pseudoplastic behavior (n < 1), with MS-PD showing a stronger viscoelastic structure (G′ > G″) and higher initial viscosity (K = 63.67 Pa sⁿ). As for powder wall coatings, MS-WPI (FD) demonstrated greater thermal stability (degradation > 200 °C). The contact angle was lower than 90° for all powders except for MS-WPI (FD), which exhibited more hydrophobic behavior. The adsorption isotherms of powders showed type II behavior, with a good fit to the GAB model (R² > 0.99). Monolayer moisture content (Xₘ) varied according to the system, being higher in freeze-dried formulations. It is concluded that the MS-PD combination, particularly when processed by spray-drying, produces powders with excellent structural properties, making it a promising candidate for use as a stable functional coating for food and supplement applications, owing to its protective and structural roles. These findings highlight the potential of modified pinhão starch composites as sustainable wall materials for developing functional and stable food and nutraceutical powders.

This study explores the use of modified starch from Araucaria angustifolia (pinhão) combined with natural biopolymers to produce functional and stable powders. The results demonstrate the potential of these materials as sustainable coating agents for food and nutraceutical applications, reinforcing the valorization of native resources and contributing to the development of clean label ingredients aligned with the principles of the bioeconomy and the conservation of Brazilian biodiversity.

研究了以改性pinh o （Araucaria angustifolia）淀粉为原料，经微波（MS）与聚葡萄糖（PD）、部分水解瓜尔胶（PHGG）或乳清分离蛋白（WPI）复合，喷雾干燥（SD）或冷冻干燥（FD）制备的不同壁材的吸附特性和热力学性能。流变性能表明分散体表现出假塑性行为（n <； 1），其中MS-PD表现出较强的粘弹性结构（G′> G″）和较高的初始粘度（K = 63.67 Pa s n2）。至于粉末墙面涂料，MS-WPI （FD）表现出更高的热稳定性（降解>； 200°C）。除MS-WPI （FD）外，其余粉末的接触角均小于90°，表现出更强的疏水行为。粉末的吸附等温线表现为II型行为，符合GAB模型（R²> 0.99）。单层含水率（X²）因体系而异，在冻干配方中较高。综上所述，MS-PD组合，特别是经喷雾干燥处理后，可以生产出具有优异结构性能的粉末，由于其保护和结构作用，使其成为食品和补充剂应用中稳定功能涂层的有希望的候选者。这些发现突出了改性pinh o淀粉复合材料作为可持续壁材的潜力，可用于开发功能稳定的食品和营养保健粉。摘要本研究探索了将阿卡aria angustifolia （pinh o）的变性淀粉与天然生物聚合物结合，以生产功能稳定的粉末。结果表明，这些材料作为食品和营养保健应用的可持续涂层剂的潜力，加强了本地资源的价值增值，并有助于开发符合生物经济原则和保护巴西生物多样性的清洁标签成分。

As innovative delivery vehicles, nanocochleates can improve the stability and controlled release of dihydromyricetin (DHM). However, the mechanisms by which calcium chloride (CaCl₂) influences the formation of nanocochleates′ unique cylindrical structure, as well as its effect on their stability and release performance, remain unclear. To address these issues, DHM-loaded nanocochleates were prepared with 6.25, 12.5, and 25 mM CaCl₂ to assess their influences on the physicochemical and structural properties of the nanocochleates. The results showed that nanocochleates prepared with the highest CaCl₂ concentration (25 mM) and incorporated with 5 mg of DHM achieved the highest encapsulation efficiency (85.29 ± 0.12 %), zeta potential (–20.53 ± 0.97 mV), antioxidant activity (50.46 ± 0.63 %), and apparent water solubility (57.25 ± 0.51 %). Scanning electron microscopy (SEM) images showed elongated cylindrical structures in the nanocochleates, and X-ray diffraction (XRD) analysis confirmed their distinctive organization. Fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC) confirmed that DHM was effectively encapsulated within the nanocochleates through ionic interactions. Nanocochleates prepared with 25 mM CaCl₂ exhibited excellent stability over 28 days and demonstrated superior in vitro controlled release of DHM (64 %–81 %) compared to DHM suspension (99 %) after 8 h in gastrointestinal medium.

纳米螯合物可以提高二氢杨梅素（DHM）的稳定性和控释能力，是一种新型的给药载体。然而，氯化钙（CaCl2）影响纳米藻酸盐独特圆柱形结构形成的机制，以及对其稳定性和释放性能的影响尚不清楚。为了解决这些问题，我们分别用6.25、12.5和25 mM CaCl2制备了负载dhm的纳米螯合物，以评估它们对纳米螯合物的物理化学和结构性质的影响。结果表明,nanocochleates氯化钙浓度最高的准备( 25毫米)和注册5 毫克DHM实现封装效率最高(85.29 ±0.12  %),电动电势(-20.53 ±0.97  mV),抗氧化活性(50.46 ±0.63  %),和明显的水溶解度(57.25 ±0.51  %)。扫描电镜（SEM）和x射线衍射（XRD）分析证实了其独特的组织结构。傅里叶变换红外光谱（FTIR）和差示扫描量热法（DSC）证实，DHM通过离子相互作用被有效地包裹在纳米螯合物中。25 mM CaCl2制备的纳米酸盐在28天内表现出优异的稳定性，并且在胃肠道培养基中8 h后，DHM的体外控释（64 % -81 %）优于DHM混悬液（99 %）。

The effects of three osmotic agents (glucose, sorbitol and sucrose) and four cultivars of peach were analysed in osmotically dehydrated fruit slices followed by convective air drying (OD+D). A comprehensive analysis of mass transfer parameters, and organoleptic, nutritional and nutraceutical properties was conducted, which included, for the first time, mineral composition and antimicrobial and enzymatic inhibitory activities in peach OD+D slices. Osmotic pretreatment improved the inhibition of protease, α-amylase and α-amyloglucosidase activities and the contents of tannins, flavonoids, phenolics and calcium in the OD+D treatment compared with those in the fresh fruit. Thus, OD+D adds value to a natural product, rendering peach slices that can be used in industry or consumed as snacks, with a sugar content equivalent to or lower than that of other fruits. Moreover, higher antimicrobial capacity and metabolite and antioxidant capacity retention were observed in OD+D than in exclusively hot-air-dried fruits. Clustering analysis of the OD+D slices displayed that the samples were grouped on the basis of the cultivar but not by the osmotic agents used for pretreatment, which is in line with the results of the statistical analysis, which revealed that the color; antioxidant capacity; ascorbic acid, carotenoid, phenolic, flavonoid, and protein contents; inhibition of α-amylase and protease activity; and bacterial growth of the OD+D samples were independent of the osmotic agents used. The results obtained demonstrate that the choice of cultivar is a key determinant of the properties of the resulting dehydrated peach and reveal new benefits of osmotic pretreatment prior to convective-drying.

分析了3种渗透剂（葡萄糖、山梨醇和蔗糖）和4个品种的桃果片在对流空气干燥（OD+D）后的渗透脱水效果。本文首次对桃OD+D切片的传质参数、感官、营养和营养保健性质进行了综合分析，其中包括矿物质组成、抗菌活性和酶抑制活性。与鲜果相比，渗透预处理提高了OD+D处理对蛋白酶、α-淀粉酶和α-淀粉葡糖苷酶活性的抑制作用以及单宁、黄酮类、酚类物质和钙的含量。因此，OD+D增加了天然产品的价值，使桃子片可以用于工业或作为零食食用，其含糖量相当于或低于其他水果。此外，OD+D处理的抗微生物能力、代谢物和抗氧化能力均高于纯热风干果。对OD+D切片的聚类分析表明，样品是按品种分组的，而不是按预处理所用渗透剂分组的，这与统计分析的结果一致，显示颜色；抗氧化能力;抗坏血酸、类胡萝卜素、酚类、类黄酮和蛋白质含量；α-淀粉酶和蛋白酶活性的抑制；OD+D样品的细菌生长与所使用的渗透剂无关。结果表明，品种的选择是水蜜桃脱水特性的关键决定因素，并揭示了对流干燥前渗透预处理的新益处。

This study investigated the impact of the use of ultrasound on the processing of the nectar made from nance (B. crassifolia) fruit, which is rich in bioactive compounds, and compared pasteurization techniques (70, 80 and 90 °C) with emerging technologies assisted by ultrasound (40, 50 and 60 °C). The objective was to evaluate the preservation of quality, the inactivation of enzymes (polyphenoloxidase - PPO and peroxidase - POD) and the bioaccessibility of its compounds. The physicochemical and microbiological characteristics and the concentrations of the bioactive compounds (anthocyanins, flavonoids, antioxidants, phenolic compounds and β-carotene) were tested. The results indicate that thermosonication, at moderate temperatures, preserved the essential physicochemical properties of the nectar, maintaining soluble solids, pH and titratable acidity. Pasteurization at 90 °C was more effective for inactivating PPO, while thermosonication at 50 °C showed special POD inactivation. Turbidity values remained within the recommended range for nectar quality under both treatments. It is concluded that, when choosing between the techniques, one should consider the thermal stability of the target enzymes, seeking a balance between enzyme inactivation and the preservation of product quality. Thermosonication is, however, a viable alternative for the processing of nectar made from the fruit of B. crassifolia and preserves its essential properties.

本研究研究了超声波对富含生物活性化合物的南楠果花蜜加工的影响，并比较了巴氏灭菌技术（70、80和90°C）和超声辅助下的新兴技术（40、50和60°C）。目的是评估其质量的保存，酶（多酚氧化酶- PPO和过氧化物酶- POD）的失活及其化合物的生物可及性。测定了花青素、黄酮类化合物、抗氧化剂、酚类化合物和β-胡萝卜素等生物活性物质的理化、微生物学特性和浓度。结果表明，在适当的温度下，热超声保存了花蜜的基本物理化学性质，保持了可溶性固形物、pH和可滴定酸度。90°C的巴氏灭菌对PPO失活更有效，而50°C的热超声对POD失活更有效。在两种处理下，浊度值都保持在甘露质量的推荐范围内。综上所述，在选择两种技术时，应考虑目标酶的热稳定性，在酶失活和保持产品质量之间寻求平衡。然而，热超声处理是一种可行的替代方法，可以处理由金合欢果实制成的花蜜，并保留其基本特性。

Herbal residues, specifically mint and lemon balm stems, were successfully converted into carbonaceous adsorbents via an eco-friendly method involving chemical activation with H₃PO₄. This low-temperature and straightforward transformation of waste biomass yielded biocarbons that were subjected to detailed physicochemical analysis, including evaluation of their pore structure, surface chemistry, electrokinetic properties, and thermal stability. The main aim of this study was to investigate the adsorption performance of these materials toward ionic polymers with different chemical characteristics – the anionic poly(acrylic acid) and the cationic polyethyleneimine – as well as to assess their effectiveness in the simultaneous removal of structurally diverse organic pollutants from aqueous solutions.

The resulting activated biocarbons were characterised by a moderately developed surface area (950–1146 m²/g), a strongly mesoporous structure (with an average pore diameter of 4.63–5.12 nm), and surface functionalities enriched with both acidic and basic groups, with a total content ranging from 0.794 to 0.987 mmol/g. This unique combination of textural and chemical properties makes them highly effective for capturing ionic polymer contaminants from aqueous systems. The maximum adsorption capacities reached 430.3 mg/g for poly(acrylic acid) and 495.9 mg/g for polyethyleneimine, which is the highest amount of these compounds adsorbed on carbonaceous materials reported in the literature so far.

It was further observed that the presence of one polymer reduced the adsorption efficiency of the other. Regeneration experiments indicated that polyethyleneimine could be removed with water only to a limited extent (17.4–20.5 %), while NaOH proved to be the most suitable desorbing agent for poly(acrylic acid) (64.5–71.8 %). Overall, the study demonstrates that activated biocarbons derived from herbal waste, with carefully engineered physicochemical properties, provide an effective and reusable solution for eliminating various ionic polymer contaminants from wastewater.

草药残留物，特别是薄荷和柠檬香草茎，通过一种环保的方法，用H₃PO₄化学活化，成功地转化为碳质吸附剂。这种对废弃生物质的低温直接转化产生了生物碳，并对其进行了详细的物理化学分析，包括对其孔隙结构、表面化学、电动特性和热稳定性的评估。本研究的主要目的是研究这些材料对具有不同化学特性的离子聚合物（阴离子聚丙烯酸和阳离子聚乙烯亚胺）的吸附性能，并评估它们同时去除水溶液中结构不同的有机污染物的有效性。所得活性炭具有中等发育的比表面积（950 ~ 1146 m²/g）、强介孔结构（平均孔径为4.63 ~ 5.12 nm）和富含酸性和碱性基团的表面官能团（总含量为0.794 ~ 0.987 mmol/g）。这种独特的结构和化学性质的组合使它们非常有效地从水系统中捕获离子聚合物污染物。对聚丙烯酸和聚亚胺的最大吸附量分别达到430.3 mg/g和495.9 mg/g，是目前文献报道的这两种化合物在含碳材料上的最高吸附量。进一步观察到，一种聚合物的存在降低了另一种聚合物的吸附效率。再生实验表明，水对聚乙烯亚胺的去除率有限（17.4 ~ 20.5 %），而NaOH是最适合聚丙烯酸的解吸剂（64.5 ~ 71.8 %）。总体而言，该研究表明，从草药废弃物中提取的活性炭具有精心设计的物理化学特性，可为消除废水中的各种离子聚合物污染物提供有效且可重复使用的解决方案。

Lipid nanoparticulate systems are efficient as active carriers with tailorable interfacial, crystallization profiles. In this study, medium−long chain diacylglycerol (MLCD)−based solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) were constructed for curcumin (Cur) delivery to enhance its oral bioavailability and their Pickering stabilizing effects were evaluated. Cur−SLNs and NLCs stabilized by different surfactants, were prepared with particle sizes ranging from 148 to 305 nm. The nanoparticles were taken up by Caco-2 cells through clathrin and caveolae mediated endocytosis pathway, with the uptake efficiency of the NLCs being 2.25 −3.94 fold higher than that of free Cur. The nanoparticles effectively inhibited the LPS−induced inflammatory response in RAW 264.7 cells, resulting in a 60 % reduction in NO secretion. Furthermore, these SLNs/NLCs were utilized as Pickering stabilizers for water−in−oil (W/O) emulsions co−loaded with hydrophobic curcumin and hydrophilic NaCl. These emulsions demonstrated slow−release performance (78.23 −96.12 % retention) after 4 weeks storage and exhibited tunable rheological properties. The interfacial particles effectively acted as a solid shell, impeding the release of internal phase compounds. The Ritger−Peppas model offered the best fit for the release profiles of all Cur−loaded lipid formulations. This study provides a theoretical basis and technical support for the fabrication and application of lipid nanoparticles and Pickering emulsions as a multifunctional delivery system.

脂质纳米颗粒系统是有效的活性载体，具有可定制的界面，结晶轮廓。本研究构建了基于中长链二酰基甘油（MLCD）的固体脂质纳米颗粒（sln）和纳米结构脂质载体（NLCs）用于姜黄素（Cur）的递送，以提高其口服生物利用度，并评估了它们的皮克林稳定效应。通过不同表面活性剂的稳定，制备了粒径在148 ~ 305 nm之间的Cur−sln和NLCs。纳米颗粒通过网格蛋白和小泡介导的内吞途径被Caco-2细胞摄取，NLCs的摄取效率比游离Cur高2.25 −3.94倍，纳米颗粒有效抑制LPS诱导的RAW 264.7细胞炎症反应，导致NO分泌减少60 %。此外，这些sln /NLCs被用作疏水姜黄素和亲水NaCl负载的水/油（W/O）乳状液的Pickering稳定剂。这些乳剂在储存4周后表现出缓释性能（78.23 - 96.12 %保留率），并表现出可调节的流变性能。界面颗粒有效地充当了一个固体壳，阻碍了内相化合物的释放。Ritger - Peppas模型提供了最适合的释放档案的所有含硒脂质制剂。本研究为脂质纳米颗粒和皮克林乳剂作为多功能给药系统的制备和应用提供了理论基础和技术支持。

Menthol/hydroxypropyl-β-cyclodextrin (HP-β-CD) and menthone/HP-β-CD inclusion microcapsules were prepared by spray drying their pre-formed inclusion complexes. Phase solubility studies indicated that both menthol and menthone formed A_L-type inclusions with HP-β-CD at a 1:1 stoichiometric ratio. The thermodynamic parameters (ΔH, ΔS, and ΔG) and stability constants demonstrated that the embedding processes are spontaneously exothermic, with lower temperatures favoring these reactions. Compared to menthone, menthol exhibited a stronger affinity for HP-β-CD, making it more effective in enhancing the solubility and stability of menthol. Infrared spectroscopy and ¹H NMR analyses confirmed the successful microencapsulation of both compounds by HP-β-CD. Molecular docking further provided the proposed embedding structures and binding energies of the inclusion complexes. The findings revealed that distinct microencapsulation mechanisms (hydrogen bonding for menthol/HP-β-CD, van der Waals forces for menthone/HP-β-CD) significantly influenced performance. Menthol/HP-β-CD microcapsules had higher storage retention at 60 °C after 16 days (34.7 %), compared with 24.4 % for menthone/HP-β-CD microcapsules, while menthone/HP-β-CD microcapsules showed better thermal stability above 150 °C. These results confirm HP-β-CD microencapsulation enhances mint compounds’ stability and retention, supporting their use in food, pharmaceuticals and other fields requiring thermal processing or long storage.

采用喷雾干燥法制备了薄荷醇/羟丙基-β-环糊精（HP-β-CD）包合物和薄荷酮/HP-β-CD包合物微胶囊。相溶解度研究表明，薄荷醇和薄荷酮与HP-β-CD以1:1的化学计量比形成al型包裹体。热力学参数（ΔH， ΔS和ΔG）和稳定性常数表明，包埋过程是自发放热的，较低的温度有利于这些反应。与薄荷酮相比，薄荷醇对HP-β-CD具有更强的亲和力，从而更有效地提高了薄荷醇的溶解度和稳定性。红外光谱和1H NMR分析证实了HP-β-CD对两种化合物的成功微胶囊化。分子对接进一步提供了包合物的包埋结构和结合能。结果表明，不同的微胶囊机制（薄荷醇/HP-β-CD的氢键，薄荷酮/HP-β-CD的范德华力）显著影响了性能。薄荷醇/HP-β-CD微胶囊在60℃保存16天后的保存率（34.7 %）高于薄荷酮/HP-β-CD微胶囊的24.4 %，而薄荷酮/HP-β-CD微胶囊在150℃以上表现出更好的热稳定性。这些结果证实了HP-β-CD微胶囊可以提高薄荷化合物的稳定性和保留率，支持其在食品，药品和其他需要热处理或长期储存的领域的应用。

The use of essential oils from plants has occurred since ancient times, with their demand steadily increasing. In Southeast Asia, the white champaka flower is a well-known medicinal flower, and its essential oil holds significant value in various industries. There are numerous studies on enhancing their extraction yields using various methods. However, research into the extraction mechanism of the white champaka flower is relatively limited, despite their importance. Therefore, the study of essential oil extraction from Michelia alba D.C. or white champaka flowers was investigated using the subcritical solvent extraction method with 1,1,1,2-tetrafluoroethane (HFC-134a) as the solvent. This research analyzes the extraction mechanism and the effects of time and temperature on the extraction yield. The extraction times were varied to 20, 30, 40, and 50 min per extraction loop, and the temperatures ranged from 40 to 60°C. The results showed that increasing time or temperature significantly improved the extraction yield. Furthermore, this study also provides an agitator as an alternative method for maintaining the solute concentration difference between the inside and outside of the raw material particles. This replaces the old method used in the machine, which is called the “solvent-overfill method”. Lastly, the extraction mechanism was analyzed using mathematical modeling, including Darcy’s law, the mass transfer equation, and the Arrhenius equation. Consequently, the initial concentration of solute inside white champaka petal, the activation energy and pre-exponential constant, were evaluated to be 6.99 × 10⁻⁴ g/cm³, 18.48 kJ/mol and 9.03 × 10⁻² g/min·cm², respectively, as well as the mass transfer coefficient of the extraction at various temperatures. These discoveries are highly advantageous for further research on the extraction of other flowers under similar conditions.

自古以来，人们就开始使用植物精油，对它们的需求也在稳步增长。在东南亚，白色的champaka花是一种著名的药用花，它的精油在各个行业都有重要的价值。利用各种方法提高其提取率的研究有很多。然而，尽管白桦花具有重要意义，但对其提取机理的研究相对有限。因此，采用亚临界溶剂萃取法，以1,1,1,2-四氟乙烷（HFC-134a）为溶剂，对白含笑花和白含笑花的精油提取进行了研究。本研究分析了萃取机理，以及时间和温度对萃取率的影响。每个提取循环的提取时间分别为20、30、40和50 min，温度范围为40 ~ 60℃。结果表明，延长萃取时间或提高萃取温度均能显著提高萃取率。此外，本研究还提供了一种搅拌器作为维持原料颗粒内外溶质浓度差的替代方法。这取代了机器中使用的旧方法，即所谓的“溶剂溢出法”。最后，利用Darcy定律、传质方程和Arrhenius方程对萃取机理进行了分析。结果表明，白桦花瓣内溶质的初始浓度、活化能和指前常数分别为6.99 × 10−4 g/cm3、18.48 kJ/mol和9.03 × 10−2 g/min·cm2，以及不同温度下的萃取传质系数。这些发现对进一步研究类似条件下其他花卉的提取具有重要意义。

To mitigate probiotic inactivation and low colonization during oral delivery, continuous fibers with meat-like fibrous morphology were fabricated from a sodium alginate/karaya gum/soy protein isolate (SA/CG/SPI) matrix to gently encapsulate Lactobacillus plantarum and enable controlled release. Network density was tuned by wet spinning followed by Ca²⁺-mediated crosslinking. The effects of two calcium sources—calcium chloride (CaCl₂) and calcium gluconate—on microstructure, mechanical/thermal stability, and encapsulation-release behavior were systematically evaluated. The results indicate that CaCl₂, which dissociates rapidly, forms a denser crosslinking gradient with smaller pore sizes, effectively balancing physical barrier properties and thermal protection. This leads to a stable, sustained release in a simulated in vitro digestive environment (PBS). By contrast, the slower dissociation of calcium gluconate generated a looser network with inferior overall performance. These differences were corroborated by morphological/spectroscopic analyses and mechanical testing. After comprehensive optimization, the best comprehensive performance was achieved under 2 % CaCl₂ conditions: the tensile strength was approximately 139 kPa, the elongation at break was approximately 59.3 %, the encapsulation rate was up to approximately 85.4 %, and the cumulative release amount was approximately 7.99 log (CFU·g⁻¹) in PBS within 8 h, with a stable release trend after about 5 h. This strategy offers a scalable materials-process framework for probiotic functional foods and oral delivery systems.

为了减轻口服给药过程中益生菌的失活和低定植，用海藻酸钠/karaya gum/大豆分离蛋白（SA/CG/SPI）基质制备了具有肉样纤维形态的连续纤维，以轻柔地包裹植物乳杆菌并使其可控释放。通过湿纺丝调整网络密度，然后用Ca 2 +介导交联。系统评价了氯化钙（CaCl2）和葡萄糖酸钙两种钙源对其微观结构、机械/热稳定性和包封释放行为的影响。结果表明，CaCl2快速解离，形成更密集的交联梯度和更小的孔径，有效地平衡了物理屏障性能和热防护。这导致在模拟体外消化环境（PBS）中稳定，持续释放。相比之下，葡萄糖酸钙较慢的解离产生较松散的网络，整体性能较差。这些差异被形态学/光谱分析和力学测试证实。综合优化后，在2 % CaCl2条件下获得最佳的综合性能：抗拉强度约为139 kPa，断裂伸长率约为59.3 %，包封率约为85.4 %，在PBS中8 h内的累积释放量约为7.99 log (CFU·g−1)，约5 h后释放趋于稳定。该策略为益生菌功能食品和口服给药系统提供了可扩展的材料-工艺框架。

This study aimed to prepare soybean protein isolate hydrolysate-Schisandra chinensis polysaccharide complex (SPH-SCP) to obtain a series of Pickering emulsions for the delivery of quercetin (QUE). Fourier transform infrared spectroscopy, fluorescence spectroscopy and dynamic interfacial tension analysis confirmed that SCP and SPH form complexes through hydrogen bonding, hydrophobic interactions, and electrostatic interactions, leading to alterations in the structure of SPH and a reduction in interfacial tension. Compared with emulsion stabilized by SPH, the QUE-loaded Pickering emulsion stabilized by SPH-SCP (SPH-SCP/QUE) exhibited smaller particles (517.13 ± 1.62 nm), higher absolute values of zeta potential (−41.82 ± 1.13 mV), and improved apparent viscosities, modulus, encapsulation efficiency (91.65 ± 0.25 %), loading ability (89.93 ± 0.15 %) and stability. These properties collectively reduced the release of free fatty acids (5.09 ± 0.14 %) and QUE (17.85 ± 3.13 %), thereby enhancing the bioaccessibility of QUE. In addition, the prepared SPH-0.1 %SCP/QUE emulsion exhibited strong antibacterial activity against Staphylococcus aureus. Intake of sugar and protein production assays revealed that SPH-0.1 %SCP/QUE Pickering emulsion inhibited the carbohydrate metabolism of Staphylococcus aureus by binding pyruvate kinase. Ultraviolet spectroscopy, Fourier transform infrared spectroscopy, fluorescence spectroscopy, isothermal titration calorimetry, molecular docking and molecular dynamics simulations assays confirmed that there were strong binding affinity and interaction between QUE and pyruvate kinase. In conclusion, the Pickering emulsions fabricated in this study displayed robust QUE encapsulation capability and potent antibacterial activity. These findings demonstrate the considerable potential of emulsions for applications such as the encapsulation of bioactive compounds, intestinal health, and food preservation.

本研究旨在制备大豆分离水解蛋白-五味子多糖复合物（SPH-SCP），以获得一系列用于递送槲皮素（QUE）的皮克林乳剂。傅里叶变换红外光谱、荧光光谱和动态界面张力分析证实SCP与SPH通过氢键、疏水相互作用和静电相互作用形成配合物，导致SPH结构发生改变，界面张力降低。与乳液稳定,相比,QUE-loaded皮克林乳液稳定的SPH-SCP (SPH-SCP /是)表现出更小的微粒(517.13 ±1.62  海里),更高的绝对值电动电势(−41.82 ±1.13  mV),和改进的表观粘度,模量、封装效率(91.65 ±0.25  %),装载能力(89.93 ±0.15  %)和稳定性。这些特性共同减少了游离脂肪酸（5.09 ± 0.14 %）和QUE（17.85 ± 3.13 %）的释放，从而提高了QUE的生物可及性。此外，制备的SPH-0.1 %SCP/QUE乳剂对金黄色葡萄球菌具有较强的抗菌活性。糖的摄入和蛋白质的产生实验表明，SPH-0.1 %SCP/QUE Pickering乳剂通过结合丙酮酸激酶抑制金黄色葡萄球菌的碳水化合物代谢。紫外光谱、傅里叶变换红外光谱、荧光光谱、等温滴定量热法、分子对接和分子动力学模拟分析证实了QUE与丙酮酸激酶之间存在较强的结合亲和力和相互作用。总之，本研究制备的皮克林乳剂具有强大的QUE包封能力和有效的抗菌活性。这些发现表明，乳剂在生物活性化合物的包封、肠道健康和食品保存等方面具有相当大的应用潜力。
