However, its high moisture content makes it highly susceptible to microbiological and biochemical spoilage. Moisture removal is hence necessary to extend its shelf-life. In this study, three different drying methods were employed: tray drying (TD) at 50°C, 60°C, and 70°C; intermittent microwave drying (MWD) at 450, 720, and 900 W; and freeze drying (FD), which served as a positive control due to its ability to preserve the quality and integrity of heat-sensitive materials. Mathematical models were applied to describe drying and adsorption behaviors of the rhizomes. Quality attributes, including color values, total phenolics, total flavonoids, and antioxidant capacity of dried samples were analyzed. Microstructural properties were evaluated using synchrotron radiation x-ray tomographic microscopy, while thermal properties were determined via differential scanning calorimetry. Moisture adsorption characteristics were studied using dynamic vapor sorption. Additionally, multivariate analyses including principal component analysis (PCA) and hierarchical cluster analysis (HCA) were utilized to assess the correlation between quality parameters and classify drying conditions. The results showed that Midilli and Kucuk and Double log polynomial models were the most suitable models to describe drying and moisture adsorption behaviors. Freeze drying and tray drying better preserved color, microstructure (more porous and uniform structure), thermal properties (lower gelatinization degree), and moisture adsorption compared to microwave drying. However, microwave drying resulted in higher total phenolics, total flavonoids, and antioxidant capacity than tray drying. The application of PCA and HCA provided useful information for food processors and researchers in designing drying conditions to achieve the desired quality attributes.</p>\u0000 </div>","PeriodicalId":15932,"journal":{"name":"Journal of Food Process Engineering","volume":"48 6","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the challenges of effective calciferol delivery, hydrogels have emerged as an innovative solution that significantly enhances its bioavailability and therapeutic efficacy. Hydrogels are intricately designed to encapsulate and protect calciferol, facilitating its targeted delivery to specific absorption sites within the body.

Specifically, high-viscosity fluids are typically agitated by impellers that generate predominantly circular flow, such as anchors. However, modifying other flow directions is important to improve mobility in areas of stagnation. In this context, this research presents a conceptual numerical contribution by designing a new anchor-type impeller geometry. The design features a zigzag-bladed anchor impeller symmetrically aligned with its shaft, aimed at enhancing axial mobility while almost retaining effective wall-scraping performance. The study focuses on analyzing the flow behavior and energy consumption inside a cylindrical tank equipped with the studied impeller, while considering the effects of various control parameters. These include the non-Newtonian behavior index of the fluid (0.6 ≤ <i>n</i> ≤ 1.4), ranging from a shear-thinning fluid to a shear-thickening fluid, the Reynolds number (1 ≤ Re ≤ 50, anchor-type agitators operate at low Reynolds number in stirred tank, which is common in mixing high-viscosity fluids), which highlights the rotational speed of the impeller, and finally, the angle of inclination of the zigzag blades (0 ≤ α 30°); beyond the 30° angle (for α &gt; 30°) there are dead zones in the upper part of the tank, which have a negative influence on mixing. The theoretical study is governed by the Navier–Stokes equations in a laminar flow regime, which are solved using the finite element method with the Galerkin approach. The numerical results have demonstrated a significant enhancement in both hydrodynamic and energetic performance. In terms of hydrodynamic performance, the axial velocity has been notably enhanced, which helped break up stagnant zones and increased axial mobility within the agitated tank. Regarding energy consumption, the new anchor design showed its capability to reduce energy usage by up to almost 47%, with the most significant reductions occurring at moderate Reynolds numbers, particularly in industries handling shear-thickening fluids.</p>\u0000 </div>","PeriodicalId":15932,"journal":{"name":"Journal of Food Process Engineering","volume":"48 5","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
