1. 1. Competitive Protein Adsorption during Spray-drying

   Författare :Karin Landström; Livsmedelsteknik; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties

   Författare :Kristina Mosén; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; carbohydrate; insulin; process conditions; crystallinity; degradation; particle size; spray drying; inhalation;

   Sammanfattning : The interest in spray drying for production of inhalable particles has grown considerably since the late 1980s. However, which process variables that control degradation and the solid state properties have not been subject to extensive research. This thesis deals with how important characteristics of inhalation particles can be controlled, i.e. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Jessica Elversson; Göran Alderborn; Anna Millqvist-Fureby; Lars Hovgaard; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Drying kinetics, coalescence and agglomeration of dairy products particles

   Författare :Loredana Malafronte; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single particle; stickiness; agglomeration; spray drying; modelling; drying-kinetics; coalescence; dairy;

   Sammanfattning : Spray drying is used in the food, pharmaceutical, and chemical industries for producing powder from a liquid feed. The unique advantages of spray drying are producing powders of a specific particle size and moisture content, handling heat sensitive products, and high capacity. However, spray drying is a complex process. LÄS MER
