This study evaluated the effects of different pretreatments (sodium carbonate solution (SCP), ethanol (ETP), blanching (BP), and ultrasound (USP)) on drying (70 °C), nutritional composition, phenolic profile, and bioactive stability of potato peel powder. As a value-added product, the resulting powder can be applied in food formulations as a natural antioxidant source and fiber-rich ingredient. In terms of processing, USP and ETP significantly reduced drying time compared to the control (270 min), reaching 210 min (USP) and 240 min (ETP). These treatments also increased the drying rate (USP = 0.408 g·g⁻¹·min⁻¹; ETP = 0.451 g·g⁻¹·min⁻¹) and the effective moisture diffusivity (USP = 4.12 ×10⁻¹⁰ m²·s⁻¹; ETP = 3.35 ×10⁻¹⁰ m²·s⁻¹), values up to six times higher than the control (7.22 ×10⁻¹¹ m²·s⁻¹). From a compositional perspective, the powder retained relevant levels of proteins (14.53–15.20 %), lipids (0.90–1.56 %), and minerals (8.02–9.20 %), highlighting their nutritional potential. HPLC analysis identified 21 phenolic compounds, with emphasis on catechin, epicatechin gallate, p-coumaric acid, and caffeic acid. DSC analysis confirmed greater thermal stability of the samples treated with USP (ΔH = 28.09 J/g) and SCP (ΔH = 25.11 J/g), suggesting greater applicability of the powder in processes involving heating. During 180 days of storage at 20 °C and 85 % relative humidity, the pretreatments significantly reduced losses of bioactive compounds (≈12–15 %) compared to the control (-34.5 %). Overall, the results confirm that USP not only improved drying efficiency but also increased the retention of phenolic compounds and storage stability. The study demonstrates that integrating pretreatments with the drying route is a promising process intensification strategy to transform potato residues into stable, high-value-added functional ingredients.</div></div>","PeriodicalId":12134,"journal":{"name":"Food and Bioproducts Processing","volume":"156 ","pages":"Pages 367-380"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146185031","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}

Initial results show the possibility of transferring well-established cleaning strategies from the macro to the microscale and allow the access to scaling-related phenomena. New methods were established such as the ability to quantify the changeable flow velocity during cleaning in microscale, as well as the quantification of the cleaning rate with temporal and local resolution via image analysis. The respective results are used for cleaning modelling with the model parameters serving as a criterion for tracking scaling-related phenomena. The geometry of a channel indicates a contrasting impact on cleaning performance, with regard to a reduction in channel height. Although a narrowing of the cross-flow section due to swelling of the hydrogels could lead to possible partial blockage, which significantly reduces cleaning rate, thus increases cleaning time.

Accurately simulating, designing, and operating effective mixing and heat‑transfer conditions under vacuum remains challenging. Therefore, this study integrates computational fluid dynamics and the discrete element method (CFD–DEM) to optimize the internal geometry and operating parameters of a pilot‑scale VSP chamber. Hard red spring wheat (HRSW) was selected as the model grain, and a spheropolyhedron representation was adopted to capture its faceted yet rounded morphology. The particle model was calibrated to match an experimental angle of repose of 23.4° using 50 corners, a corner smoothness of 0.2, and a rolling resistance of 0.35. A 3 ³ factorial DEM study evaluated the effects of baffle count (10, 15, 20), baffle angle (20°, 25°, 30°), and rotational speed (12, 18, 24 rpm) on particle distribution and unloading efficiency. The optimal configuration—10 baffles set at 20° and a rotational speed of 18 rpm—produced uniform particle dispersion and a 96.74 % unloading efficiency. Subsequent CFD–DEM coupling predicted that 50 kg of wheat would reach 45 °C after 6.5 min of preheating with hot air at 100 °C. A pilot chamber fabricated using the optimized geometry was experimentally validated, requiring 12 min to reach 45 °C and achieving a 94.98 % unloading efficiency. Together, the coupled simulations and prototype trials demonstrate improved thermal response and reduced preheating time relative to earlier designs. These findings highlight the value of DEM‑guided design optimization for enhancing heat‑transfer performance in VSP systems and provide a scalable framework for improving the pasteurization of low‑moisture food grains.</div></div>","PeriodicalId":12134,"journal":{"name":"Food and Bioproducts Processing","volume":"156 ","pages":"Pages 92-103"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145939728","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}

While paper-based options offer potential recyclability, cured meats pose challenges due to the multi-material packaging required for their extended shelf-life. This study evaluates the environmental and economic sustainability of three packaging systems, i.e. plastic multi-material (MM), paper-based (PA) and a hybrid plastic and paper-based packaging (HY) for sliced cooked ham, considering both direct and indirect effects through the Life Cycle Assessment (LCA) methodology. The functional unit was one packaging unit containing 100 g of sliced cooked ham. The MM was the most environmentally sustainable overall, as its longer shelf-life reduced food waste. The HY system had the highest environmental impact, mainly due to its shorter shelf-life and the environmental burden of combining paper and plastic. Paper-based systems had a lower environmental impact when focusing solely on the packaging life cycle due to paper’s recyclability and lower production burden. Considering the techno-economic analysis (TEA) of the three packaging, while PA and HY systems delivered marginally lower direct unit costs than MM, it retained the smallest share of value lost as waste per gram (0.135 % (MM) vs 0.144 % (HY) and 0.177 % (PA)), confirming its higher economic robustness alongside its environmental lead. The study underscores the complexity of evaluating food packaging systems and highlights the importance of enhancing barrier properties in paper-based packaging to reduce waste. It advocates for a holistic design approach that prioritizes material selection, recyclability, and shelf-life extension, emphasizing that shelf-life is a critical factor in LCA.</div></div>","PeriodicalId":12134,"journal":{"name":"Food and Bioproducts Processing","volume":"156 ","pages":"Pages 37-46"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145839701","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}

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.

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.

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.
