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

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Bella Nielsen; Alva Rodhe; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Lipase in oat endosperm: The effect of freeze-drying and oven-drying

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Ilham Hassan; [2021]
    Keywords : Lipase; oat endosperm; whole grain oat flour; water activity.;

    Abstract : The project was carried out in collaboration with Lantmännen with the aim to analyse the lipase activity in oat endosperm, non-heat-treated whole grain oat flour and heat-treated whole grain oat flour and to investigate whether lipase activity could be inactivated in oat endosperm by reducing water activity by various methods such as oven drying and freeze drying to extend oat shelf life. Lipase activity was measured by a wet extraction of the flour and an artificial substrate that gives a coloured product if lipase enzymes are active in the extract. READ MORE

  4. 3. Endosperm-based postzygotic hybridization barriers in Arabidopsis and Capsella

    University essay from SLU/Dept. Of Plant Biology

    Author : Mohammad Foteh Ali; [2021]
    Keywords : Endosperm development; Parental conflict; Genetic diversity; Auxin;

    Abstract : In Arabidopsis, endosperm development is very important for viable seed development. Especially, endosperm cellularization is a crucial event for embryo survival and if it fails, can lead to embryo arrest, as observed in seeds derived from interploidy and interspecies hybridization.

  5. 4. Characterizaion of the mechanism underlying auxin-induced seed arrest in Arabidopsis thaliana

    University essay from SLU/Dept. Of Plant Biology

    Author : Sowmiya Devi Venkatesan; [2020]
    Keywords : endosperm; hybridization barriers; triploid block; auxins; RNA Polymerase IV; RNA silencing;

    Abstract : In flowering plants, seeds are produced as a result of double fertilization, whereby the haploid egg cell and the diploid central cell fuse with one of the two haploid sperm cells giving rise to a diploid embryo and a triploid endosperm, respectively. The endosperm serves as the major nutrient source for the developing embryo yet the molecular mechanisms pertaining to its development are not fully understood. READ MORE

  6. 5. Effect of extrusion cooking on β-glucan and fructan in wheat and rye bran

    University essay from SLU/Dept. of Food Science

    Author : Ramanath Bhat; [2013]
    Keywords : β-glucan; fructan; extrusion cooking; wheat bran; rye bran;

    Abstract : In cereal industry, when cereal grains are milled to extract the starchy endosperm for white flour, large quantities of bran are classed as by-products and end up in animal feed. Bran, depending on the extraction rate, comprises of small amount of germ and endosperm along with aleurone layer, nucellar epidermis, seed coat and fruit coat. READ MORE
