  2. 1. 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.

  4. 2. 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

  5. 3. Soil organic carbon in permafrost terrain : Total storage, landscape distribution and environmental controls

    Author : Gustaf Hugelius; Peter Kuhry; Jan Boelhouwers; Stockholms universitet; []
    Keywords : ;

    Abstract : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). To a large degree, this SOC is stored in permafrost soils and peatlands and is vulnerable to remobilization under future global warming and permafrost thawing. READ MORE

  6. 4. Trees to supercapacitors: green energy storage for sustainable future

    Author : Bony Thomas; Kristiina Oksman; Mohini Sain; Milo Shaffer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : Currently the world is transitioning to a fossil free and circular economy-based development to achieve the environmental and climate objectives along with the sustainable development goals. To achieve this target, efficient use of resource materials is important, which can increase the lifetime and economic value of the resources while decreasing both the extraction of new raw materials and landfill waste.

  7. 5. Packaging methods and storage time : effects on beef quality

    Author : Åsa Lagerstedt Norström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Consumers base their purchasing choices on perceived quality and a bright red colour of beef is to many a sign of freshness and good meat quality, making colour the most important quality attribute for retailers. The most common consumer packaging types for beef in Sweden is high-oxygen modified atmosphere packaging (MAP), with the gas composition (80% O₂; 20% CO₂). READ MORE
