  1. 1. Verifiering av ny extraktionsmetod för analys på oljeindex

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Theodor Hägglund; [2023]
    Nyckelord :metodverifiering; oljeindex; gaskromatografi; extraktion;

    Sammanfattning : Huvudsyftet med detta examensarbete var att verifiera en ny metod för extraktion av olja från jord-, slam-, och sedimentprover som ska ersätta företagets befintliga metod. Extraktionen sker på ett skakbord som förbehandling innan den extraherade oljan sätts på en GC-FID för att analysera dess oljeindex mellan C10-C40 samt dess olika specifika delfraktioner. LÄS MER

  3. 2. Alkaline Protein Extraction of Oat Bran and Oat Endosperm Flour - the Effect of pH during Extraction and Precipitation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Bella Nielsen; Alva Rodhe; [2021]
    Nyckelord :Oats; Protein; Alkaline extraction; Protein extraction; Plant-based proteins; Oat protein; Oat bran; Oat endosperm; Iso-electric precipitation; Food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : An increased understanding of the negative impacts of animal-based proteins, on both environment and health, has led to a rise in the demand for plant-based proteins. To meet the demands, conventional crops must be efficiently utilized. LÄS MER

  4. 3. Soil erosion by water : Estimating soil loss and sediment yield in the southern half of Sweden by using the Revised Universal Soil Loss (RUSLE) model

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ella Myr; [2021]
    Nyckelord :Soil erosion; water erosion; soil loss; RUSLE; rainfall erosivity; soil erodibility;

    Sammanfattning : Soil erosion has been recognized as an increasing threat to the environment and humans worldwide as anthropogenic activities have accelerated the soil degradation rate. In Sweden, it is estimated that 15% of the arable land is affected by soil erosion, and studies have shown that fields in the south of Sweden lose a substantial amount of soil under certain weather conditions.

  5. 4. Effects of afforestation and crop systems on the water balance in the highlands of Ethiopia

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Rebecca Naomi Ter Borg; [2020]
    Nyckelord :Acacia decurrens; landscape water balance; sediment yield; soil and water conservation; SWAT modelling; water balance partitioning;

    Sammanfattning : In the Upper Blue Nile Basin land use is rapidly changing due to agricultural development and intensification with potential effects on the water availability both up- and downstream. This study is aimed to explore the impact of agricultural land use change on a landscape water balance. LÄS MER

  7. 5. Functionality of oat based food ingredients

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Charlott Vikenborg; Fay Stensson; [2020]
    Nyckelord :Oat protein; beta-glucans; food technology; livsmedelsteknologi; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : This master thesis work was performed in collaboration with the agricultural cooperative Lantmännen. With the ambition to take a world leading role in the development of unique products based on oats, Lantmännen has developed two oat based powders; one protein powder, PrOatein™, and one β-glucan powder, PromOat®.
