36. Membrane emulsification: modelling interfacial and geometric effects on droplet size
Sammanfattning : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. LÄS MER
37. Numerical Studies of Mixing in Pipes and Static Mixers
Sammanfattning : The objective of the present work was to investigate the mixing process in static mixers under laminar flow conditions, and in pipes during the displacement of dissimilar liquids. A numerical scheme and a method of characterizing static mixers were developed. LÄS MER
38. 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.

39. Whey protein adsorption and aggregation on modified stainless steel surfaces in relation to fouling
Sammanfattning : This thesis focuses on the possibilities to reduce fouling by 1.Modifying the stainless steel surface. LÄS MER
40. Texture and color of potato products
Sammanfattning : Texture and color are the most important parameters in the definition of the quality of potato products, but usually their subjective measurements do not give any reproducible results due to the complicating factors related to human perception. In order to understand the factors that can affect the texture and the color of the potato products during processing, instrumental techniques have been developed for quantifying those parameters.
