  2. 1. Lipid Oxidation in Fillets of Herring (Clupea harengus) during Processing and Storage

    Author : Ingrid Undeland; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipid oxidation; processing; storage; fish; Herring; Clupea harengus;

    Abstract : The influence of storage and processing on the development of lipid oxidation in herring fillets was investigated and related to their composition of lipids, catalysts and antioxidants. The progress of oxidation was monitored as antioxidant loss and as the development of primary, secondary and tertiary lipid oxidation products. READ MORE

  4. 2. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Author : Karin Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

    Abstract : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. READ MORE

  5. 3. Quality of Frozen Rainbow Trout. Effects of different freezing and thawing treatments

    Author : Katarina Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane disintegration; liquid loss; centrifuged tissue fluid; fish; lysosomal enzyme; frozen storage; glazing; freezing; sensory quality; rainbow trout; thawing;

    Abstract : The effects of different freezing, frozen storage and thawing treatments on the muscle tissue of farmed rainbow trout (Oncorhychus mykiss) were studied. Biochemical measurements were correlated to sensory estimated quality changes. The freezing process affects the proteins, the lipid fractions and the membrane structures in the fish muscle.

  6. 4. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials

    Author : Semhar Ghirmai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hemoglobin; herring Clupea harengus ; fish; rainbow trout Oncorhynchus mykiss ; erythrocyte; hemolysis; side-stream; antioxidant; lipid oxidation; blood plasma;

    Abstract : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. READ MORE

  7. 5. Local and global contaminants in Swedish waters : studies on PCBs, DDTs, 4,5,6-trichloroguaiacol and their transformation products in fish and sediments

    Author : Maria Söderström; Åke Bergman; Bert van Bavel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCB; DDT; HCB; trichloroguaiacol; transformation products; dimerisation; bromination; environmental pollutants; eutrophication; lakes; fresh water; baltic sea; monitoring; sediments; fish; phytoplankton; PCB; DDT; HCB; triklorguajakol; omvandlingsprodukter; dimerisering; bromering; miljöföroreningar; eutrofiering; sjöar; sötvatten; östersjön; miljöövervakning; sediment; fisk; fytoplankton; miljökemi; Environmental Chemistry;

    Abstract : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. READ MORE
