  2. 1. Retrogradation Properties of Starch

    Author : José Silverio; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; lipids; degree of polymerization DP ; isothermal microcalorimetry; differential scanning calorimetry DSC ; crystallinity; amylose; amylopectin; gelatinization; starch; retrogradation; temperature cycling; PCA; Food and drink technology; Livsmedelsteknik;

    Abstract : The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included.

  4. 2. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results

    Author : Dan Johansson; Ulf Germgård; Pedro Fardim; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kraft cooking; softwood; hardwood; cellulose; xylan; glucomannan; degradation; dissolution; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. READ MORE

  5. 3. Bioplastics from Biomass - Acetylation of Xylans with Green Chemistry

    Author : Agnes Stépán; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : There is social, environmental and increasing economic pressure on the industrial sector to substitute non-renewable resources with renewable ones as the increasing World population is exponentially depleting the fossil fuel supplies of the Earth. Each year about 260 million tons of plastics are produced from crude oil and most of it ends up as waste. READ MORE

  6. 4. The biology and properties of wood for nanocellulose production

    Author : Anne Bünder; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood is a renewable and environmentally friendly raw material envisioned for the production of novel materials. In this interdisciplinary thesis project, I investigated genetic factors controlling cellulose biosynthesis, cellulose microfibril dimensions, wood mechanical properties and factors that influence nanocellulose extraction from wood.

  7. 5. Innovative processing of brown seaweed for value-added products

    Author : Leila Allahgholi; Bioteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The increasing depletion of fossil fuels, rising greenhouse gas emissions, and a growing global population have increased the need for sustainable food and energy sources. Traditional industrial biotechnology, which relies on plant-based feedstocks, competes with food production for arable land. READ MORE
