  1. 1. Competitive Protein Adsorption during Spray-drying

    Author : Karin Landström; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; pyrene; quenching; fluorescence; beta-casein; beta-lactoglobulin; bovine serum albumin; milk proteins; Spray-drying; competitive adsorption; Surface and boundary layery chemistry; Ytkemi; gränsskikt;

    Abstract : The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. READ MORE

  2. 2. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

    Author : Liang Li; Chalmers University of Technology; []
    Keywords : airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

    Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique.

  3. 3. Microstructure of spray dried particles at different scales of drying

    Author : Marine Nuzzo; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

    Abstract : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. READ MORE

  4. 4. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts

    Author : Jessica Elversson; Göran Alderborn; Anna Millqvist-Fureby; Lars Hovgaard; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Spray drying; Particle formation; Density; Protein formulation; Encapsulation; Coating; Competitive adsorption; Polymer; ESCA; AFM; FTIR; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.

  5. 5. Pharmaceutical Nanocomposites : Structure–Mobility–Functionality Relationships in the Amorphous State

    Author : Joel Hellrup; Denny Mahlin; Göran Alderborn; László Fábián; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amorphous; pharmaceutical composites; solid state; structure; molecular mobility; spray-drying; freeze-drying; moisture sorption; physical stability; compression; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. READ MORE
