This work concerns the use of Natural Deep Eutectic Systems (NADES) as sustainable extraction solvents to obtain a bioactive extract, from beetroot peels (BRP), that can be used in food or cosmetic applications. BRP are considered a agrifood waste and often underutilized, although they are rich in phytochemicals with bioactive properties (antioxidant, anti-inflammatory, neuroprotective, and anti-carcinogenic). In this work, the objective was to develop a sustainable, efficient, and extraction method of those valuable compounds, using NADES as solvents and efficient extraction methods. Furthermore, the role of NADES in the stabilization and preservation of these bioactive compounds was also studied. Among the various NADES tested, the one composed of betaine and glycerol (BG), showed the highest extraction efficiency and resulted in extracts with superior antioxidant activity. Optimized extraction conditions were found to be 40°C using a 1:20 solid-to-liquid ratio, with BG. The use of NADES not only improved extraction yield, but also improved the stability of BRP bioactive compounds over a longer period of time. This allows for the extract to be used together with NADES, as a liquid, without the need to remove the extraction solvent. The results confirm that NADES are a promising alternative to conventional solvents and have potential uses in nutraceutical or functional food applications. The study underscores the potential of BRP as a sustainable source of natural antioxidants and highlights a circular approach to waste utilization.

这项工作涉及使用天然深共晶系统（NADES）作为可持续提取溶剂，从甜菜根皮（BRP）中获得生物活性提取物，可用于食品或化妆品应用。尽管BRP富含具有生物活性（抗氧化、抗炎、神经保护和抗癌）的植物化学物质，但它被认为是一种农业食品废弃物，往往未得到充分利用。本研究的目的是以NADES为溶剂，采用高效的提取方法，开发一种可持续、高效的提取这些有价化合物的方法。此外，还研究了NADES在稳定和保存这些生物活性化合物中的作用。甜菜碱和甘油（BG）组成的NADES提取率最高，提取物抗氧化活性较好。最佳提取条件为40℃，料液比1:20，加BG。NADES的使用不仅提高了提取率，而且提高了BRP生物活性化合物在较长时间内的稳定性。这允许提取物与NADES一起作为液体使用，而不需要去除提取溶剂。结果证实，NADES是一种很有前途的传统溶剂替代品，在营养保健或功能食品应用中具有潜在的用途。该研究强调了BRP作为天然抗氧化剂的可持续来源的潜力，并强调了废物利用的循环方法。

Grain cleaning is one of the most important processes in rice processing. Mixtures of rice husks and brown rice with high jet velocity and high feed rates can be separated by multi-baffle separation ducts for grain cleaning. However, the rice husks cannot be completely separated from the brown rice, resulting in the presence of residual rice husks in the cleaned brown rice. Therefore, it is necessary to explore the formation mechanism of residual rice husk. In this work, we simulate the separation process of rice husk from brown rice by coupling Computational Fluid Dynamics (CFD) and Discrete Element Method (DEM) and explore the two stages separation based on the interaction between multiple baffles. The results show that the interaction between primary separation and secondary separation affects the quality of separation. Specifically, the collision between rice husk and brown rice in the primary separation region affects the landing position of the husk in the secondary separation region. And the secondary separation quality is related to the landing position of the husk in the secondary separation region and the number of collisions between the husk and the falling brown rice from the primary separation region. It was demonstrated that the residual husk could be effectively reduced by increasing the distance between the landing position of the husk in the secondary separation region and the brown rice outlet. The research results can provide analytical ideas and theoretical direction for the design and parameter selection of multistage separator and similar equipment.

稻米清洗是稻米加工的重要工序之一。稻壳和糙米的混合物具有高射流速度和高进料速率，可采用多挡板分离管进行颗粒清洗。然而，稻壳不能与糙米完全分离，导致清洗后的糙米中存在残留的稻壳。因此，有必要对残谷壳的形成机理进行探讨。本文采用计算流体力学（CFD）与离散元法（DEM）相结合的方法，模拟了稻壳与糙米的分离过程，探讨了基于多隔板相互作用的两阶段分离过程。结果表明，一次分离与二次分离的相互作用影响了分离质量。具体来说，一次分离区稻壳与糙米的碰撞影响了稻壳在二次分离区的落地位置。二次分离质量与稻壳在二次分离区的落地位置以及稻壳与从一次分离区落下的糙米的碰撞次数有关。结果表明，增加二次分离区稻壳落地位置与糙米出口之间的距离，可有效减少稻壳残留。研究结果可为多级分离器及类似设备的设计和参数选择提供分析思路和理论指导。

Microencapsulation of lemongrass oil using modified starch (Capsul®) was investigated via spray drying to interpret the process–structure–transport relationships governing flavor retention and release. The effects of oil loading, emulsion size, and inlet air temperature on emulsion characteristics, citral retention, powder morphology, and stability were evaluated. Increasing oil content resulted in larger emulsion droplets, reduced emulsification efficiency, and greater surface oil content, leading to lower citral retention. Capsul® demonstrated high encapsulation performance, retaining up to 40 wt% lemongrass oil with minimal losses. Emulsion droplet size emerged as a key structural determinant, with smaller droplets yielding superior retention and reduced surface oil. By integrating microstructural analysis with kinetic modeling, this study demonstrates that drying-induced particle architecture, rather than retention efficiency alone, governs long-term stability. Release profiles were well described by Avrami kinetics, confirming diffusion-controlled transport, with larger droplets and higher oil loading exhibiting increased effective diffusivity. Although inlet air temperature had minimal influence on immediate citral retention, it strongly affected powder microstructure: higher temperatures produced larger particles with thinner walls, whereas temperatures below 140 °C increased residual moisture, lowered glass transition temperature, and accelerated volatile release. These findings provide mechanistic guidance for the rational design and optimization of spray-drying processes to tailor the stability and release performance of encapsulated flavor systems.

通过喷雾干燥研究了变性淀粉（capsule®）对香茅精油的微胶囊化，以解释控制风味保留和释放的过程-结构-运输关系。考察了载油量、乳化液粒径和进风温度对乳化液特性、柠檬醛保留率、粉末形态和稳定性的影响。含油量的增加导致乳滴变大，乳化效率降低，表面含油量增加，导致柠檬醛保留率降低。胶囊®具有高封装性能，保留高达40% wt%柠檬草油，损失最小。乳化液液滴的大小是决定乳化液结构的关键因素，液滴越小，乳化液的保持性越好，表面油含量越低。通过将微观结构分析与动力学建模相结合，该研究表明，干燥诱导的颗粒结构，而不仅仅是保留效率，决定了长期稳定性。Avrami动力学很好地描述了释放曲线，证实了扩散控制运输，更大的液滴和更高的油负荷表明有效扩散系数增加。虽然入口空气温度对柠檬醛的即时滞留影响很小，但它强烈影响粉末的微观结构：较高的温度产生更大的颗粒，壁更薄，而低于140°C的温度会增加残余水分，降低玻璃化转变温度，加速挥发性释放。这些研究结果为合理设计和优化喷雾干燥工艺，以定制胶囊风味体系的稳定性和释放性能提供了机制指导。

In chocolate processing plants, cleaning with water-based cleaning agents is not possible since when in contact with water, sugar and milk powder within the chocolate agglomerate which causes blocking of the plants. Common elastomere-based cleaning pigs pose the risk of contaminating through abrasion and have specific design requirements. Research is now focusing on using highly concentrated sugar-in-oil suspensions as flexible cleaning pigs. The rheology of these suspensions is complex, allowing for various compositions. This study presents a simulative pre-design of these pigs using the volume-of-fluid method, targeting challenging components like L-bow pipes and continuous expansions. Simulations systematically varied the rheological properties of the pig-suspension in terms of the Bingham number (

) and the Reynolds number (

1 0^{- 4}

–

). The massflows investigated were

. Strong shear-thinning behavior emerged as crucial for creating cohesive pigs with effective cleaning capabilities. No correlation with yield stress was found when the pig was flowable, although values in range

2 – 2000 Pa

were investigated. The tested parameter combinations did not achieve satisfactory contour adaptivity for pigs during continuous expansion. The resulting residual soil layers on the walls and the proportion of soil in the outlet mass flow were up to

在巧克力加工厂，不可能使用水基清洗剂进行清洁，因为它会与巧克力团块中的水、糖和奶粉接触，从而导致工厂堵塞。常见的弹性体清洁清管器存在磨损污染的风险，并且有特定的设计要求。目前的研究重点是使用高度浓缩的油中糖悬浮液作为灵活的清洁猪。这些悬浮液的流变性是复杂的，允许各种成分。本研究采用流体体积法对这些清管器进行了模拟预设计，主要针对l型管和连续膨胀等具有挑战性的部件。模拟系统地改变了猪悬液在宾汉姆数（10−3-102）和雷诺数（10−4-101）方面的流变特性。所研究的质量流量分别为90,180,360kg/h。强大的剪切减薄行为对于创造具有有效清洁能力的粘性猪至关重要。尽管在2-2000Pa范围内进行了研究，但在猪可流动时，没有发现屈服应力与屈服应力的相关性。试验参数组合对猪在连续膨胀过程中的轮廓自适应效果不理想。所得的壁面残留土层和出口质量流中土壤的比例比参考冲洗过程降低了50%。

In this study, the structural and functional properties of collagen hydrolysates were evaluated in a simulated gastrointestinal digestion model. Collagen peptides were produced by enzymatically hydrolyzing bovine gelatin in the presence of selected bioactive compounds, including a phenolic acid (gallic acid), a flavonoid (quercetin), and a non-phenolic antioxidant vitamin (ascorbic acid). The results demonstrated that collagen peptides obtained under these conditions exhibited enhanced antioxidant activity. However, during the gastric phase, phenolic-enriched samples partially inhibited pepsin activity, leading to limited proteolysis and reduced molecular weight decline. This indicates that phenolic compounds, when present during hydrolysis, can interact with digestive enzymes and modulate protein digestion. Such interactions may not always generate synergistic effects; instead, they may result in phase-dependent modulation, where early gastric digestion is hindered but intestinal hydrolysis is restored. These findings highlight the importance of evaluating the digestive behavior of phenolic–protein systems to better understand their nutritional and functional implications in the development of functional foods and nutraceuticals.

在这项研究中，胶原蛋白水解物的结构和功能特性在模拟胃肠消化模型中进行了评估。胶原蛋白肽是在选定的生物活性化合物存在下通过酶水解牛明胶产生的，包括酚酸（没食子酸）、类黄酮（槲皮素）和非酚类抗氧化维生素（抗坏血酸）。结果表明，在这些条件下获得的胶原肽具有增强的抗氧化活性。然而，在胃期，富含酚的样品部分抑制胃蛋白酶活性，导致有限的蛋白质水解和减轻分子量下降。这表明，当水解过程中存在酚类化合物时，可以与消化酶相互作用并调节蛋白质的消化。这种相互作用不一定总能产生协同效应；相反，它们可能导致相依赖性调节，其中早期胃消化受到阻碍，但肠道水解恢复。这些发现强调了评估酚蛋白系统消化行为的重要性，以更好地了解其在功能食品和营养保健品开发中的营养和功能意义。

Plasma-treated liquids as an environmentally friendly alternative to conventional disinfectants for the hygienization of food processing facilities – first insights in shelf life characteristics and antibacterial efficacy 等离子体处理液体作为食品加工设施卫生的传统消毒剂的环保替代品-首次了解保质期特性和抗菌功效

Plasma-treated liquids (PTL) are produced using atmospheric pressure plasma and therefore contain reactive nitrogen species and reactive oxygen species. Due to these reactive species, the liquids exhibit an antimicrobial effect. Therefore, their use as disinfectants is being widely investigated, especially for the food industry. However, there are only a few studies on the efficacy of freshly prepared or stored PTLs on their use as surface disinfectants.

In our studies, we produced PTLs from two different base liquids, saline and deionized water, by treatment with an arc discharge plasma jet. The liquids were characterized after production using sum parameters of the reactive species (pH, oxidation-reduction-potential (ORP) and electrical conductivity). Both PTLs were additionally characterized during storage. In microbiological studies, the antibacterial efficacy of fresh PTLs was tested on different surfaces (acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC) and stainless steel). Our studies revealed that all PTL types achieve a reduction over 4 log, even though the characteristics differ. The antibacterial efficacy of PTL from saline was additionally evaluated during storage and decreased slightly, which is accompanied by a change in pH, ORP and electrical conductivity during the first days of storage. However, this PTL though showed good antibacterial efficacy after 8 days of storage, by inactivating up to 4.9 log of E. coli. This illustrates the potential of PTL to be used as disinfectant in food processing and production.

等离子体处理液体（PTL）是使用常压等离子体生产的，因此含有活性氮和活性氧。由于这些活性物质，液体表现出抗菌作用。因此，人们正在广泛研究它们作为消毒剂的用途，特别是在食品工业中。然而，关于新鲜制备或储存的ptl作为表面消毒剂的功效的研究很少。在我们的研究中，我们通过电弧放电等离子体射流处理从两种不同的基础液体（生理盐水和去离子水）中生产了ptl。制备后的液体用反应物质的和参数（pH、氧化还原电位（ORP）和电导率）进行了表征。在储存期间，这两种物理带库都进行了额外的表征。在微生物学研究中，对新鲜ptl在不同表面（丙烯腈-丁二烯-苯乙烯（ABS）、聚氯乙烯（PVC）和不锈钢）上的抗菌效果进行了测试。我们的研究表明，所有类型的PTL都可以减少4 log以上，即使特征不同。生理盐水PTL的抑菌效果在贮藏过程中被进一步评价，在贮藏的第一天，PTL的pH值、ORP值和电导率都有轻微的下降。然而，该PTL在储存8天后显示出良好的抗菌效果，对大肠杆菌的灭活率高达4.9 log。这说明了PTL在食品加工和生产中作为消毒剂的潜力。

The antibacterial efficacy of PTL from saline was additionally evaluated during storage and decreased slightly, which is accompanied by a change in pH, ORP and electrical conductivity during the first days of storage. However, this PTL though showed good antibacterial efficacy after 8 days of storage, by inactivating up to 4.9 log of <em>E. coli</em>. This illustrates the potential of PTL to be used as disinfectant in food processing and production.</div></div>","PeriodicalId":12134,"journal":{"name":"Food and Bioproducts Processing","volume":"156 ","pages":"Pages 152-160"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purification of sinapic acid (SA) from mustard bran hydrolysate through a membrane filtration-adsorption chromatography combined process was developed in this work. Ultrafiltration (UF) treatment (UH030, 30 kDa, 1.4 bar) successfully removed 98 % proteins without influencing SA content. Nanofiltration (NF) treatment (NP010, 1 kDa, 10 bar) removed most solutes larger than 300 Da while allowing 85 % of SA to pass into the permeate. UF or NF alone resulted in 2–3 times increase in SA purity, yet neither process significantly increased the antioxidant activity of the hydrolysate. UF coupled with XAD16 adsorption concentrated SA by 13-fold and increased its purity 40-fold to 20 % w/w (74 % recovery). NF combined with adsorption concentrated SA by 17-fold and increased its purity 110-fold to 55 % w/w (60 % recovery). The purified fraction exhibited strong antioxidant activity. This work has demonstrated that the combined process of membrane filtration and adsorption chromatography is promising for the purification of SA from agro-industrial by-product streams.

研究了膜过滤-吸附色谱联合纯化芥菜皮水解液中辛酸的工艺。超滤（UF）处理（UH030, 30 kDa, 1.4 bar）成功去除98 %的蛋白质，而不影响SA含量。纳滤（NF）处理（NP010, 1 kDa, 10 bar）去除了大部分大于300 Da的溶质，同时允许85 %的SA进入渗透液。单独使用UF或NF可使SA纯度提高2-3倍，但两种处理均不能显著提高水解产物的抗氧化活性。UF偶联XAD16吸附SA浓度提高13倍，纯度提高40倍，达到20 % w/w（回收率为74 %）。NF与浓缩的SA结合，其纯度提高了17倍，达到55 % w/w（回收率60 %），提高了110倍。纯化后的部分具有较强的抗氧化活性。研究结果表明，膜过滤和吸附色谱相结合的方法是纯化农工副产物中SA的有效方法。

Techno-economic analysis (TEA) of emerging technologies aids in establishing the economic benefits and technical feasibility of novel technologies. In this study, a techno-economic model was developed for a non-thermal synergistic pasteurization of apple juice based on a combination of UV-A light and aqueous extract derived from olive byproduct, and its comparison with conventional thermal pasteurization processes. A comparative TEA revealed that UV-A + OPE pasteurization could reduce ca. 30.2–38.3 % of direct-fixed capital (DFC) and ca. 19.5–23.9 % of annual operating costs (AOC) compared to conventional thermal pasteurization (low-temperature long-time [LTLT] and high-temperature short-time [HTST] pasteurization) at a production scale of 1000 kg/batch. In addition, UV-A + OPE pasteurization exhibited lower sensitivity to upscaling than HTST pasteurization, and ca. 27.4 % lower AOC was estimated at a production scale of 2000 kg/batch. These findings highlight the potential of UV-A + OPE pasteurization to enhance the economic sustainability of juice processing while ensuring the microbial safety of juice products. This study provides insights into developing a non-thermal pasteurization process using a synergistic combination of UV-A light and plant byproduct-derived extracts and evaluating its economic feasibility through a comparative TEA.

新兴技术的技术经济分析有助于确定新技术的经济效益和技术可行性。在这项研究中，基于橄榄副产品的UV-A光和水提取物的组合，建立了苹果汁非热协同巴氏杀菌的技术经济模型，并与传统的热巴氏杀菌工艺进行了比较。对比TEA显示，在1000 kg/批次的生产规模下，与传统的热巴氏灭菌（低温长时间[LTLT]和高温短时间[HTST]巴氏灭菌）相比，UV-A + OPE巴氏灭菌可降低直接固定资本（DFC）约30.2 - 38.3% %，年运营成本（AOC）约19.5 - 23.9% %。此外，UV-A + OPE巴氏灭菌对放大的敏感性低于HTST巴氏灭菌，在2000 kg/批次的生产规模下，AOC估计降低了27.4 %。这些发现强调了UV-A + OPE巴氏灭菌在确保果汁产品微生物安全的同时提高果汁加工的经济可持续性的潜力。本研究提供了利用UV-A光和植物副产品提取物的协同组合开发非热巴氏杀菌工艺的见解，并通过比较TEA评估其经济可行性。

New strategies for monitoring and improving flushing processes used in chocolate manufacturing 监测和改进巧克力生产中使用的冲洗工艺的新策略

In the chocolate industry, product changes are performed as flushing processes, in which one product is displaced by a subsequent product. The end of the process is detected by visual assessment based on the color change of the discharged product. Due to limited process knowledge and a lack of suitable measuring systems, these processes have so far been designed with rigid process parameters and large safety factors.

First, the authors experimentally evaluated three measurement methods – surface acoustic wave-based (SAW), capacitance-based (CMS) and camera-based (CAM) – on a horizontal DN 25 test rig and compared them to a reference cross-section measurement. SAW demonstrated the highest potential, as it can distinguish between the two fluids most effectively. CMS is suitable for draining or pigging processes with air phases in the system and CAM for end-point measurements, since it permits the analysis of the residual layers close to the wall.

The authors also investigated two alternative strategies for product changeover – simple flushing after a draining process (partially filled pipe) and flushing sequences – using experiments and numerical models. All strategies were compared to a conventional industrial product changeover with identical process times of 40 s. Flushing sequences showed the greatest benefit, reducing flushing mass by up to 32 %, while the other strategy mainly enabled direct product recovery. These findings demonstrate that targeted measurement methods and new flushing strategies can substantially reduce product loss in product changes in industrial chocolate processing.

在巧克力工业中，产品变化是通过冲洗过程进行的，其中一种产品被随后的产品取代。根据排出产品的颜色变化，通过目视评估来检测工艺的结束。由于有限的工艺知识和缺乏合适的测量系统，迄今为止，这些工艺的设计具有严格的工艺参数和大的安全系数。首先，作者在水平dn25测试台上实验评估了三种测量方法——基于表面声波（SAW）、基于电容（CMS）和基于相机（CAM），并将它们与参考截面测量进行了比较。SAW表现出了最大的潜力，因为它可以最有效地区分两种流体。CMS适用于系统中空气相的排水或清管过程，CAM适用于终点测量，因为它允许分析靠近壁面的残余层。作者还研究了产品转换的两种替代策略-在排水过程（部分填充管道）后的简单冲洗和冲洗顺序-使用实验和数值模型。所有策略都与传统工业产品转换进行了比较，相同的过程时间为40 s。冲洗顺序显示出最大的效益，减少冲洗质量高达32% %，而其他策略主要是实现直接产品回收。这些发现表明，有针对性的测量方法和新的冲洗策略可以大大减少工业巧克力加工中产品变化的产品损失。

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。
