    University dissertation from Div of Technical Analytical Chemistry, Center for Chemistry and Chemical Engineering

    Author : Bengt Wittgren; Lunds universitet.; Lund University.; [1997]
    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 : Popular Abstract in Swedish Denna avhandling behandlar storlekskarakterisering av stora molekyler (polymerer) med en ny teknik, nämligen flödesfältflödesfraktionering (flödesFFF). Det aktuella storleksområdet som studerats i avhandlingen är intervallet mellan några få nanometer(nm) upp till en halv mikrometer (um). READ MORE

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

    University dissertation from Henrik Stålbrand, dep. Biochemistry Lund University

    Author : Jon Lundqvist; Lunds universitet.; Lund University.; [2002]
    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

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

    University dissertation from Department of Applied Nutrition and Food Chemistry, Lund University

    Author : Maria Svanberg; Lunds universitet.; Lund University.; [1997]
