  2. 1. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation

    Author : Bengt Wittgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-angle light scattering; molar mass distribution; aggregation; size characterisation; Asymmetrical flow FFF; water-soluble polymers; polysaccharides; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. READ MORE

  4. 2. The Challenges of Analyzing the Molecular Properties of Starch

    Author : Daysi Pérez; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amaranthus caudatus; Chenopodium quinoa; Chenopodium pallidicaule; Canna indica; Lepidium meyenii; Xanthosoma sagittifolium; Manihot esculenta; starch; amylose; amylopectin; field-flow fractionation; size distribution; dissolution;

    Abstract : Both the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. READ MORE

  5. 3. Appearance of Textured and Pigmented Polymeric Surfaces

    Author : Sofie Ignell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; perception; gloss; surface texture; polymer; colour;

    Abstract : The surface appearance is of great importance in the production of high-quality injection-moulded products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour, gloss and texture. READ MORE

  6. 4. Development of High-Protein Oat for the Feed and Food Industry

    Author : BINDU SUNILKUMAR; Kemicentrum Centrum för preventiv livsmedelsforskning; []
    Keywords : Oats; protein; mutation; segregation; dietary fibre; βglucan; lipids; electophoresis; amino acids; fractionation; avenin; ; dietary fibre; amino acid; beta glucan; crossing; amplification; quality; quantity; high protein; fractionation;

    Abstract : Oats are an excellent source of high-quality proteins, with a favourable amino acid composition. Oat proteins therefore have greatpotential to complement existing animal and plant protein sources, especially if the protein content could be increased. In this thesis,high-protein oat lines were identified and characterised. READ MORE
