    Sammanfattning : Popular Abstract in Swedish Syftet med studierna som presenteras i denna avhandling har varit att undersöka om fordonsetanol kan framställas på ett lönsamt och energieffektivt sätt från restprodukter från jord- och skogsbruk enligt svenska förhållanden. Mycket av den forskning som rör andra-generationens etanolproduktion går ut på att förfina och förbättra de separata delstegen i framställningsprocessen. LÄS MER

  2. 2. Alkylresorcinols as biomarkers of whole grain wheat and rye intake

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Rikard Landberg; Sveriges lantbruksuniversitet.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Dietary biomarkers are objective measures of food or nutrient intake and can be related to endpoints in epidemiological studies, used in the validation of dietary assessment instruments and used to check of compliance during intervention studies. Alkylresorcinols (AR), phenolic lipids present exclusively in the outer parts of wheat and rye grains, have been suggested as biomarkers of whole grain wheat and rye intake. LÄS MER

  3. 3. Utilization of Andean grain flours in the development of wheat flour dough

    Detta är en avhandling från Department of Food Technology, Lund University

    Författare :Sander Jonathan Pérez Villarroel; Lunds universitet.; Lund University.; [2019-08-24]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheat; Andean grains; Amaranth; Amaranthus caudatus; Canahua; Chenopodium pallidicaule; Quinoa; Chenopodium quinoa; Dough; Substitution; Ultracentrifugation; Phase separation; Dough composition; Macroscopic separation; Freezable water; Textural properties; Compression; Uniaxial tension; Biaxial tension; Principal component analysis; Partial least square regression; Bread;

    Sammanfattning : Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelastic material, with different responses to deformations, in order to contribute to possibilities for improvements in dough analysis and development of novel products.

    Sammanfattning : Popular Abstract in English The world’s resources of fossil fuels are rapidly being depleted, and we now know that the combustion of these fuels leads to the emission of greenhouse gases resulting in climate change. It is therefore imperative that we develop renewable sources of fuel. LÄS MER
