  3. 7. Freeze-Dried Wheat Gluten-Based Foams

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Wheat gluten; Glutenin; Gliadin; Renewable; Freeze-drying; Pore structure; Baceterial cellulose; Glycerol; Mechanical properties; Thermal conductivity; Combustion properties;

    Sammanfattning : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. LÄS MER

  4. 8. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Mats K G Johansson; Lars Kloo; KTH; []
    Nyckelord :Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

    Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER

  5. 9. Improved Techniques for Sampling and Sample Introduction in Gas Chromatography

    Författare :Jonas Bonn; Johan Roeraade; Åsa Emmer; Mikael Hedenqvist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gaskromatografi; Provupparbetning; Provintroduktion; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Sampling and sample introduction are two key steps in quantitative gas chromatography. In this thesis, a development of a previously described sampling technique as well as a novel concept for sample introduction in gas chromatography are presented. The thesis is based on two papers.

  7. 10. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Författare :Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. LÄS MER
