  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. Isolation, characterization and enzymatic hydrolysis of water-soluble wood polysaccharides

    Author : Jon Lundqvist; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; size exclusion chromatography; beta-mannosidase; beta-mannanase; endoglucanase; ethyl hydoxyethyl cellulose; metabolism; Biokemi; Biochemistry; Metabolism; microwave irradiation; O-acetyl-galactoglucomannan; isolation;

    Abstract : The need for new renewable products has enhanced the interest in cellulose and hemicellulose as raw material. The wood plant cell wall is a complex mixture of cellulose, hemicellulose, lignin and minor amounts of pectin, proteins and extractives. Several interactions between the compounds make them difficult to separate without modification. READ MORE

  5. 3. Effects of Processing on Dietary Fibre in Vegetables

    Author : Maria Svanberg; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low molecular weight carbohydrates; carrot cultivars; molecular weight distribution; viscosity; water-soluble polysaccharides; processing; Dietary fibre; vegetables; bulking capacity; rats; Food and drink technology; Livsmedelsteknik;

    Abstract : Several beneficial effects have been connected with dietary fibre. Insoluble fibre has a good faecal bulking capacity, whereas soluble and viscous dietary fibre has been shown to have beneficial effects on carbohydrate and lipid metabolism. READ MORE

  6. 4. Functional and Renewable Galactoglucomannan-based Hydrogels

    Author : Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Gunnar Henriksson; Margaretha Söderqvist; KTH; []
