Spray-freeze-drying: A novel process for the drying of foods and bioproducts S. Padma Ishwarya, C. Anandharamakrishnan, Andrew G.F. Stapley Abstract Spray-freeze-drying (SFD) is an unconventional freeze drying technique that produces uniquely powdered products whilst still including the benefits of conventionally freeze dried products. SFD has potential applications in high value products due to its edge… Continue reading Spray-freeze-drying: A novel process for the drying of foods and bioproducts

Comparison of Freeze and Spray Drying to Obtain Primaquine-Loaded Solid Lipid Nanoparticles Owuor James, Florence Oloo, Japheth Kibet Ngetich, Mwaiwa Kivunzya Abstract This article describes how the spray drying and freeze drying of various nanosized Solid Lipid Nanoparticle (SLN) and the physicochemical attributes of the acquired particles were examined. Primaquine loaded Solid Lipid Nanoparticles dried… Continue reading Comparison of Freeze and Spray Drying to Obtain Primaquine-Loaded Solid Lipid Nanoparticles

Thermal inactivation kinetics of microencapsulated microbial transglutaminase by ultrasonic spray-freeze drying Hilal Isleroglu, Izzet Turker Abstract Partially purified microbial transglutaminase (mTG) was microencapsulated by ultrasonic spray-freeze drying (USFD) as a novel method, using a 48 kHz ultrasonic nozzle. The microencapsulated samples, which used a mixture of inulin and gum arabic as coating materials, were compared to… Continue reading Thermal inactivation kinetics of microencapsulated microbial transglutaminase by ultrasonic spray-freeze drying

Membrane‐Freeze Concentration Hybrid for Temperature‐Sensitive Biomolecules. Investigation, Application, and Techno‐Economic Benefits Timo van Beek, Michael Budde, Jan van Esch Abstract In order to close the technology gap between membrane technologies and spray/freeze‐drying ideally with a technology that avoids thermal stress to sensitive enzyme solutions, the limits of freeze concentration for this application have been investigated.… Continue reading Membrane‐Freeze Concentration Hybrid for Temperature‐Sensitive Biomolecules. Investigation, Application, and Techno‐Economic Benefits

How different nanoparticles affect the rheological properties of aqueous Wyoming sodium bentonite suspensions Abstract Clay suspensions present complex microstructures in different environments and deep understanding of such microstructures is crucial to control their flow properties. Their rheological profile is closely linked with the structural association (3-D network) of bentonite particles. Nanomaterials are considered very good… Continue reading How different nanoparticles affect the rheological properties of aqueous Wyoming sodium bentonite suspensions

Rascón, M.X. Quintanilla-Carvajal, M. Castillo-Morales, U.R. Marín, E. Flores-Andrade Abstract Red onion microcapsules were produced by spray freezing into liquid cryogenic (SFLC) and spray drying (SD) and… Continue reading Effect of porous structure and spreading pressure on the storage stability of red onion microcapsules produced by spray freezing into liquid cryogenic and spray drying

Freeze Granulation for the Processing of Silicon Nitride Ceramics Ola Lyckfeldt, Kent Rundgren, M. Sjöstedt Abstract Freeze granulation (LS-2, PowderPro HB, Sweden) has been demonstrated as a favourable alternative to conventional granulation methods (spray drying, sieve granulation etc) in the production of granules for the pressing of high-performance ceramic powders. Freeze granulation/freeze drying prevents the… Continue reading Freeze Granulation for the Processing of Silicon Nitride Ceramics

Selective Oxidation of HMF via Catalytic and Photocatalytic Processes Using Metal-Supported Catalysts Lolli A, Maslova V, Bonincontro D, Basile F, Ortelli S, Albonetti S Abstract In this study, 5-hydroxymethylfurfural (HMF) oxidation was carried out via both the catalytic and the photocatalytic approach. Special attention was devoted to the preparation of the TiO₂-based catalysts, since this… Continue reading Selective Oxidation of HMF via Catalytic and Photocatalytic Processes Using Metal-Supported Catalysts
