  1. 1. Competitive Protein Adsorption during Spray-drying

    University dissertation from Britt Nyström, Library, Institute for Surface Chemistry, P.O.B. 5607, 114 86 Stockholm, Sweden

    Author : Karin Landström; Lund University.; Lunds universitet.; [2000]
    Keywords : 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. Drying kinetics, coalescence and agglomeration of dairy products particles

    University dissertation from Britt Nyström, Library, Institute for Surface Chemistry, P.O.B. 5607, 114 86 Stockholm, Sweden

    Author : Loredana Malafronte; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single particle; stickiness; agglomeration; spray drying; modelling; drying-kinetics; coalescence; dairy;

    Abstract : 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. READ MORE

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

    University dissertation from Lund University

    Author : Marine Nuzzo; Lund University.; Lunds universitet.; [2015]
    Keywords : 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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jessica Elversson; Uppsala universitet.; [2005]
    Keywords : 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; PHARMACY Pharmaceutics; FARMACI 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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joel Hellrup; Uppsala universitet.; [2016]
    Keywords : 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
