   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Fractionation of lipids and protein from the microalga Nannochloropsis oculata

   Author : Lillie Cavonius; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food processing; lipids; pH-shift process; n 3 polyunsaturated fatty acids; solubilization; acid; proteins; Nannochloropsis oculata; alkaline; microalgae; precipitation; in vitro digestion;

   Abstract : To feed Earth’s growing population, microalgae have been proposed as a source of protein and long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). Currently, microalgae are mainly sold either as whole biomass, or the economically valuable LC n-3 PUFA fraction is extracted with organic solvents. READ MORE

6. 4. On the Aggregation of Cereal β-Glucan and its Association with other Biomolecules : A Study using Asymmetric Flow Field-Flow Fractionation (AF4)

   Author : Claudia Zielke; Avdelningen för livsmedel och läkemedel; []
   Keywords : ß-glucan; polysaccharides; dietary fiber; field flow fractionation; Asymmetric flow field-flow fractionation AF4 ; Multiangle light scattering MALS ;

   Abstract : During recent years, numerous studies have shown the ability of dietary fiber toprotect the colon from disease and to improve intestinal health. Beneficial healtheffects, such as the lowering of blood cholesterol levels and a reduction in the risk of coronary heart disease, are often directly related to cereal β-glucan, one of the major components of dietary fiber found in oat and barley.

7. 5. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas

   Author : Betty Mbatia; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; by-products; value addition; EPA; DHA; PUFA; biogas;

   Abstract : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.
