  1. 21. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties

    Författare :Tobias Köhnke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Xylan; Hornification; Lignin-carbohydrate complexes; Cationization; Isolation; Softwood kraft pulp; Extraction; Adsorption;

    Sammanfattning : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. LÄS MER

  3. 22. Investigating the Feasibility of using Scandinavian Agricultural Side Streams for the Development of Novel High-Moisture Meat Analogues

    Författare :Izalin Zahari; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-moisture extrusion HME ; meat analogues; plant-based meat; Scandinavian side-streams;

    Sammanfattning : Meat analogues are products that are supposed to resemble meat in terms of texture, flavour, and also sensory characteristics. They have recently become increasingly popular due to numerous issues related to health, religion, environmental impact and the growing number of vegetarians and vegans. LÄS MER

  4. 23. Spiral Grain in Norway Spruce

    Författare :Harald Säll; Thomas Thörnqvist; Rolf Birkeland; Växjö universitet; []
    Nyckelord :Spiral grain angle; drying deformation; warp; wood quality; Norway spruce; Picea abies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Sammanfattning : Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture. LÄS MER

  5. 24. Dietary fibre production from oat hulls

    Författare :Eva Schmitz; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oat hulls; Dietary fibre; Chemical composition; Bleaching; Pre-treatment; Enzyme synergy;

    Sammanfattning : The current threats of climate change connected to the unsustainable consumption of fossil resources paired with an increasing world population demands the exploration of alternative raw materials for the production of food, fuel and specialty chemicals. Agricultural waste streams present suitable sources due to their availability in large quantities at low costs without competing with current food production. LÄS MER

  7. 25. Improving cellulose fibre properties by controlled adsorption of xylans

    Författare :Tobias Köhnke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Isolation; Lignin-carbohydrate complexes; Adsorption; Extraction; Tensile strength; Aggregation; Softwood kraft pulp; Cellulose fibre; Hornification; Xylan;

    Sammanfattning : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. LÄS MER
