  2. 1. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

    Author : Cecilia Arfvidsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

    Abstract : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. READ MORE

  4. 2. Freeze-Dried Wheat Gluten-Based Foams

    Author : Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Exploring the Wood Adhesive Performance of Wheat Gluten

    Author : Petra Nordqvist; Eva Malmström Jonsson; Mats Johansson; Bo Mattiasson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant protein; wood adhesive; mechanical properties; wheat gluten; soy protein isolate; gliadin; glutenin; adhesion; hydrolysis; heat treatment; AFM;

    Abstract : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.

  6. 4. Tailoring the structure-function relationship in wheat gluten : processing, genotype and environment effects in bio-based materials

    Author : Faiza Rasheed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gluten proteins ranging in size from 30 000 to several million daltons form one of the largest and most complex polymers in nature. The giant molecular nature and intricate network of the over 100 types of proteins in gluten make structural studies rather challenging. READ MORE

  7. 5. Novel uses of bio-polymers in composites : from chemistry to processing of materials and food

    Author : Faraz Muneer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plant bio-polymers obtained as industrial side-streams (wheat gluten and potato proteins) and specifically designed potato starch and hemp fibres were used to produce composite materials. Fractionated pea protein and pea dietary fibres were used to make pasta-like sheets for production of healthy food. READ MORE
