  1. 1. The Influence of Salting Procedures on the Characteristics of Heavy Salted Cod

    University dissertation from Department of Food Technology, Engineering and Nutrition, Lund University

    Author : Kristin Thorainsdottir; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; protein; water holding capacity; water; yield; Salting; protein denaturation; cod;

    Abstract : The production of heavy salted cod (bacalao) has changed from being a single-step process salting to a multistep procedure. The aim of this study was to gain a deeper understanding of water retention and yields of heavy salted cod as influenced by salting procedures. READ MORE

  2. 2. Protein Yield and Protein Isolate Quality when applying pH-shift Processing on Cod, Haddock and Blue Whiting Fillets- Effects of Replacing Centrifugation with Filtration

    University dissertation from Department of Food Technology, Engineering and Nutrition, Lund University

    Author : Helgi Nolsøe; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; fish; haddock; protein yield; Protein isolate; filtration; pH-shift processing; centrifugation; blue whiting; surimi; cod;

    Abstract : A more sustainable fishery and a better utilization of the harvested fish raw material are currently of great importance to prevent overexploitation of our marine resources. Production of protein isolates to use for example as surimi has for many years been an important way of better utilizing low-value fish species and fish rest raw materials. READ MORE

  3. 3. The dynamics in harvested populations

    University dissertation from Department of Biology, Lund University

    Author : Anders Wikström; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluctuations; temporal; state-space; Harvest; cod; vendace; elasticity; stage-structured; stochastic; growth-rate; Baltic Sea; Bothnian Bay;

    Abstract : We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the adult segment of the population is harvested. When a constant annual harvest is taken the coefficient of variation of the adult population increases for most parameter values due to the age truncation effect, i. READ MORE

  5. 5. Dynamics of astaxanthin, tocopherol (Vitamin E) and thiamine (Vitamin B1) in the Baltic Sea ecosystem Bottom-up effects in an aquatic food web

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Norbert Häubner; Pauli Snoeijs; Jon Ågren; Rhena Schumann; Markku Viitasalo; [2010]
    Keywords : Baltic Sea; carotenoids; astaxanthin; tocopherols; Vitamin E; thiamine; Vitamin B1; pelagic food web; eutrophication; M74; phytoplankton; zooplankton; sprat; Sprattus sprattus balticus; herring; Clupea harengus; salmon; Salmo salar; cod; Gadus morhua; High Performance Liquid Chromatography HPLC ; electrochemical detection ECD ;

    Abstract : The thesis combines laboratory experiments and field expeditions to study production, transfer and consumption of non-enzymatic antioxidants and thiamine in an aquatic food web. In particular, I (1) documented spatial and seasonal variation of tocopherols and carotenoids in the Baltic Sea pelagic food web, and (2) examined the effects of abiotic and biotic factors on tocopherol, carotenoid and thiamine concentrations in phytoplankton, zooplankton and fish.
