1. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers
Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

2. NMR Self-Diffusion Studies and Stability Studies of Emulsions
Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER
3. Emulsion formation and stability - Impact of the dispersed state of the emulsifier on emulsification
Sammanfattning : Emulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties.

4. Numerical and experimental study of turbulent drop breakup in high-pressure homogenizers
Sammanfattning : Emulsification is the process of making stable mixture of two or more immiscible substances (typically oil and water). The product of this process, the emulsion, is found in various applications and industries such as food (milk and other dairy products, non-dairy alternatives, mayonnaise, salad dressing), cosmetics and pharmaceuticals (creams, lotions, intravenous medications), chemical (paints, cleaning products), etc. LÄS MER
5. Dynamic Modelling of Emulsification in High-Pressure Homogenizers
Sammanfattning : Different approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended papers to their alternatives and previous suggestions. LÄS MER
