This study evaluated modified starch (MS), porous starch (PS), and maltodextrin as wall materials for improving FNJ loading during spray drying. Droplet drying behavior, physicochemical property, microstructure, and bioactive stability were investigated. Results showed that both MS and PS enabled high FNJ loading of up to 40% solids in the final powder, with distinct drying and dissolution behaviors. MS powders exhibited the shortest dissolution time (116–135 s), which was attributed to favorable hydrophilicity and rapid crust dissolution. PS powders showed slower dissolution (198–206 s) and the highest tapped bulk density, mainly due to their porous and concave particle structures that enhanced powder packing and prolonged water penetration. Total phenolic content was retained or increased after drying, reaching up to approximately 130%, while antioxidant capacity was generally maintained or improved. These findings highlight the potential of MS and PS for producing high-loading FNJ powders with adjustable functional properties.","PeriodicalId":11374,"journal":{"name":"Drying Technology","volume":"1 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared to conventional spray drying processes, typically using droplets of 10-200 micron in diameter generated by high-shear spraying, RTAD uses much smaller droplets with diameter 0.1 to 20 microns produced in modified liquid atomization processes. These fine droplets evaporate rapidly within 10-100 ms at room temperature conditions, thereby reducing drying-induced stresses for thermally sensitive biologics. In this study, we employed Green Fluorescent Protein (GFP) as a model biological molecule to optimize the RTAD system design and process parameters. We experimentally investigated the effects of droplet size, multiphase flow patterns in the drying chamber, and usage of polysorbate 20 as a model surfactant on GFP fluorescence after drying and powder reconstitution. The experiments demonstrated that the presence of surfactant in the formulation significantly influenced GFP fluorescence intensity, especially for smaller droplets. The numerical studies using Computational Fluid Dynamics simulations revealed that the intensity of GFP fluorescence in the produced dry powders was dependent on the patterns of multiphase flow in the drying chamber. Non-axisymmetric flows and closed circulating streamlines near the drying gas inlet resulted in considerably longer particle residence times and subjected GFP molecules to excess stress that negatively impacted the GFP fluorescence intensity. Through iterative optimization of the chamber design, process parameters and feedstock formulation, we achieved recovery of the GFP fluorescence intensity that exceeded 96% in the obtained dry powders. This work establishes GFP as a sensitive model biologic and its fluorescence intensity as a powerful tool to rapidly assess process efficiency and the ability to preserve bioactivity after dehydration. The study has broad implications for the design and scale-up of drying technologies, which can potentially transform the production of dry powder biopharmaceuticals.</p>","PeriodicalId":11374,"journal":{"name":"Drying Technology","volume":"43 14","pages":"2068-2082"},"PeriodicalIF":3.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13298357/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148344238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These findings suggest that ultrasonic pretreatment results in a brighter coloration of the strawberry samples. The ultrasound − assisted freezing treatment groups exhibited a significantly higher free radical scavenging ability compared with the nonultrasonic treatment group. This enhancement was attributed to the ultrasonic pretreatment, which increased the concentrations of total phenolic compounds, flavonoids, and anthocyanins, and effectively inhibited the activities of polyphenol oxidase and peroxidase, thereby reducing the content of red pigment in the strawberry samples. Furthermore, confocal laser scanning microscopy revealed a uniform distribution of sugar within the samples following ultrasonic treatment. Cluster analysis indicated that the primary indices influencing the color of the samples were total phenolic content and peroxidase activity. Therefore, the ultrasonic pretreatment method effectively enhances product color, inhibits enzyme activity, and increases anthocyanin content. This technology holds promising development prospects.","PeriodicalId":11374,"journal":{"name":"Drying Technology","volume":"42 13","pages":"2032-2043"},"PeriodicalIF":0.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147882205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
