  1. 1. Factors Influencing Phytate Degradation in Piglets. Feed phytate behaviour and degradation by microbial phytases

    Författare :Katrine Pontoppidan; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pigs; in vitro digestion; P. lycii; inositol phosphates; phytate; phytase;

    Sammanfattning : Phytate, the main storage form of phosphorus (P) in plant feedstuffs, is indigestible for monogastric animals, and phytases are therefore used as feed additives to increase the digestibility of phytate-P and limit the inclusion of inorganic P. However, new and improved phytases are needed to obtain better phytate digestibility and allow for lower inclusions of inorganic P. LÄS MER

  2. 2. Fermentation of quinoa, canihua and amaranth to degrade phytate and improve mineral bioavailability

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

    Författare :Vanesa Castro-Alba; Lund University.; Lunds universitet.; [2019-09-27]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quinoa; Canihua; Amaranth; Iron; Zinc; Calcium; Phytate; Fermentation; Accessibility; Bioavailability;

    Sammanfattning : Plant-based diets are the main source of nutrients for vegetarians worldwide and for low-income inhabitants of developing countries, such as in rural areas of Bolivia. These diets may contain high levels of mineral inhibitors such as phytate that impairs mineral absorption in the human gut. LÄS MER

  3. 3. On yeasts from traditional fermented foods - Characterization, phytate degradation, strain improvement and applications

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Linnea Qvirist; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytase; Saccharomyces cerevisiae; Phytate; Pichia kudriavzevii; Phenotypic Characterization; Goat Milk; Food Fermentation; Kluyveromyces marxianus; Yaghnob Valley;

    Sammanfattning : Plant materials naturally contain minerals of iron, zinc and calcium. However, plants also contain a compound called phytic acid, which can chelate the minerals and form insoluble complexes. Minerals from plant foods are unavailable for intestinal uptake when they are bound in phytate complexes. LÄS MER

  4. 4. 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

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Ann-Katrin Haraldsson; [2005]
    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. 5. Yeast biotechnology for nutritional improvements of fermented cereal-based foods - Phytate degradation and folate production

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Andreas Hellström; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mineral availability; phosphate; togwa; starter culture; Yeast; food fermentation; phytase; phytate; folate;

    Sammanfattning : Anaemia is a serious public health problem in nearly all developing countries. It has negative consequences on cognitive and physical development of children, reduces work capacity in adults, and increases the risk of maternal and child mortality. LÄS MER
