1. 1. Drop Break-up in High-Pressure Homogenisers

   Författare :Fredrik Innings; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; plasma; fluiddynamik; Gaser; plasmas; fluid dynamics; POD; Gases; PIV; Eddy; Flow; Jet; Milk; Break-up; Emulsion; Drop; Homogeniser;

   Sammanfattning : The overall aim of this project was to investigate the drop break-up process in milk homogenisers. This was done by measurements and calculations of the flow fields in the gap region and by visualisation of drops being broken up. To make visualisation and measurements possible, two scale models of a homogeniser gap were developed. LÄS MER

3. 2. The Physicochemical and Sensory Properties of Fruit and Vegetable Fibre Suspensions - The Effect of Fibre Processing and its Addition to Low-Fat Sausages

   Författare :Hanna Bengtsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; carrot; apple; potato pulp; tomato; sensory perception; low-fat sausages; texture; heat treatment; homogenisation; Dietary fibre suspensions;

   Sammanfattning : Due to the health effects of dietary fibre, as well as its water-holding capacity (WHC), food products are commonly fortified with fibre-rich sources. However, to be able to design food products with specific textural properties that also appeal to the consumer, it is important to understand and to characterise the physicochemical and chemical properties of the fibre.

4. 3. Influence of Escherichia coli feedstock properties on the performance of primary protein purification

   Författare :Mattias Råvik; Andres Veide; Åsa Emmer; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Downstream processing; cell surface properties; surface plasmon resonance; contact angle measurements; microelectrophoresis; aqueous two-phase partitioning; filtration; EBA adsorbents; high-pressure homogenisation; Biochemistry; Biokemi;

   Sammanfattning : Abstract The aim of the present study was to increase the understanding of how the cell surface properties affect the performance of unit operations used in primary protein purification. In particular, the purpose was to develop, set up and apply methods for studies of cell surface properties and cell interactions. LÄS MER

5. 4. Processing of raw Cassava (Manihot esculenta) - Experiments and Modelling

   Författare :Carola Rojas; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylopectin; hydrodynamic radius; field flow fractionation; overlap concentration; minerals; enzymes; cassava; hydrolyses; glucose; maltose; sucros; amylase; hydrolyses kinetics; starch granule structure; radius of gyration; drying kinetics; heat transfer; high pressure homogenisation; mass transfer;

   Sammanfattning : The objective of the present thesis was to understand how the quality and performance of dried cassava products could be developed by drying and other processing steps. This goal was achieved in several stages. LÄS MER

7. 5. In vitro Bioaccessibility of Carotenes: Influence of microstructure in tomato and carrot as modified by processing

   Författare :Cecilia Svelander; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; α-carotene; in vitro bioaccessibility; high-pressure homogenisation; carrot; in vivo bioavailability; Caco-2 cell model; blanching; processing; Lycopene; β-carotene; tomato; microstructure;

   Sammanfattning : Carotenes are a group of fat-soluble pigments in many fruits and vegetables associated with several important biological effects, like protection against the development of some forms of cancer and cardiovascular disease. The carotene bioavailability in plant foods, i.e. LÄS MER
