    Sammanfattning : During recent years, numerous studies have shown the ability of dietary fiber toprotect the colon from disease and to improve intestinal health. Beneficial healtheffects, such as the lowering of blood cholesterol levels and a reduction in the risk of coronary heart disease, are often directly related to cereal β-glucan, one of the major components of dietary fiber found in oat and barley.

  2. 2. Characterization of Starch Using Flow Field-Flow Fractionation Techniques

    Författare :Catalina Fuentes; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To improve the properties and functionality of starch, it is important to understand the physicochemical and structural characteristics as raw material, after being modified to increase its characteristics and/or during changes due to the processing conditions. For this reason, the objective of the present thesis is to improve the understanding of characteristics and molecular properties like molar mass (M), root-mean-square radius (rrms) and their relation to other physicochemical properties of starch extracted from different sources.

    Nyckelord :Oats; protein; mutation; segregation; dietary fibre; βglucan; lipids; electophoresis; amino acids; fractionation; avenin; ; dietary fibre; amino acid; beta glucan; crossing; amplification; quality; quantity; high protein; fractionation;

    Sammanfattning : Oats are an excellent source of high-quality proteins, with a favourable amino acid composition. Oat proteins therefore have greatpotential to complement existing animal and plant protein sources, especially if the protein content could be increased. In this thesis,high-protein oat lines were identified and characterised. LÄS MER
