  1. 1. Properties of modified starches and their use in the surface treatment of paper

    Författare :Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER

  3. 2. Modified Starches in aqueous and plastisol coating

    Författare :Agneta Jansson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Polyvinyl alcohol; Water vapor barrier; Tensile properties; Rheology; Chemical Engineering; Kemiteknik;

    Sammanfattning : The interest for coatings containing renewable materials has enlarged in the last decade. Materials from the nature are investigated like starch, cellulose derivatives, protein (gelatin), chitosane by many. In this study potato starch has been used. LÄS MER

  4. 3. Interactions between Amylose, Native Potato, Hydrophobically Modified Potato and High Amylopectin Potato Starches

    Författare :Fernando Ortega-Ojeda; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DSC; rheology; starch; polymers;

    Sammanfattning : The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry).
