  1. 1. Hydrothermal Processing of Cereals Optimal Conditions for Phytete Degradation and Myo-Inositol Formation. Effect on Phytase Activity and Mineral Absorption

    Författare :Eva-Lotta Bergman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rye; rice; barley; wheat; myo-inositol; calcium absorption; phytase; hydrothermal processing; zinc absorption; phytate;

    Sammanfattning : The aim of this thesis was to optimise a hydrothermal process to degrade phytate (myo-inositol hexaphosphate), increase the level of free myo-inositol and preserve phytase activity in cereals with the purpose to achieve products with improved mineral bioavailability. Phytate is known to impair mineral absorption and myo-inositol is considered to be a semi-essential nutrient. LÄS MER

  3. 2. Phytases in Saccharomyces cerevisiae. Exploring genes and proteins for the improvement of strains

    Författare :Jenny Veide; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; phytase; yeast; acid phosphatase; in vitro digestion; PHO; Saccharomyces cerevisiae; phytate; myo-inositol hexaphosphate;

    Sammanfattning : Degradation of myo-inositol hexaphosphate (InsP6, phytate) in food or feed by InsP6-degrading enzymes (phytases) is known to increase the availability of minerals and phosphate, which leads to a higher nutritional value. The aim of this work was to explore the extracellular degradation of InsP6 by Saccharomyces cerevisiae. LÄS MER

  4. 3. Malting of Barley for healthy foods. Optimal conditions for phytate removal and preservation of ?-glucan, in vitro iron availability and degradation of phytate and ?-glucan during in vitro digestion

    Författare :Ann-Katrin Haraldsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phytate; Saccharomyces cerevisiae; iron availability; barley; phytase activity; beta-glucan; in vitro digestion; malting; Caco-2 cells;

    Sammanfattning : A high concentration of phytate (myo-inositol hexaphosphate) in cereals is known to impair absorption of dietary minerals. The aim of this work was to optimize a malting procedure to degrade phytate and/or increase phytase activity in barley to improve iron availability and to preserve the content of β-glucan, since β-glucan is associated with health promoting properties and is therefore of nutritional interest.

  5. 4. Cereal- and Microbial Phytases. Phytate Degradation, Mineral Binding and Absorption

    Författare :Maria Türk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mineral binding; iron absorption; cereals; phytate degradation; phytase; dietary phytases; S cerevisiae; A niger;

    Sammanfattning : Cereal foods contain large amounts of phytate (myo-inositol hexaphosphate; IP6), which is the major storage form of phosphorus, in the plant. IP6 possesses a high potential for chelating minerals, such as Fe 2+, Zn2+, Mg2+ and Ca2+. LÄS MER
