  1. 1. Nutritional Assessment in a Rural Area of Bolivia. A Study of Zinc and Iron Deficiencies and Bioavailability

    Författare :Claudia Lazarte; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zinc; iron; deficiencies; bioavailability; fermentation; developing countries; plant-based diets;

    Sammanfattning : While originally, protein-energy deficiency was considered the main factor of malnutrition, it is now understood that micronutrient deficiencies play a fundamental role in a variety of health and disease outcomes. Zinc and iron deficiencies are still highly prevalent in low-income countries, whereas insufficient intakes and diets with low mineral absorption are the major causes. LÄS MER

  3. 2. Corrosion-induced release of zinc and copper in marine environments

    Författare :Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. LÄS MER

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

    Författare :Vanesa Castro-Alba; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; 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

  5. 4. Nutritional Limitations of a Green Protein Shift with Focus on Iron

    Författare :Cecilia Mayer Labba; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phytate; non-heme iron absorption; antinutrients; protein shift; protein extract; meat substitutes; plant-based; fava bean; zinc bioavailability; iron bioavailability; sustainable nutrition;

    Sammanfattning : A dietary shift into plant-based diets (PBD) to reduce the climate footprint is advocated. Effects on nutrition and health from a modern PBD, composed of replacement products based on protein extracts are however currently unknown. LÄS MER

  7. 5. Bioprocessing of Oats Influence on Phytate Hydrolysis and Mineral Bioavailability

    Författare :Marie Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc absorption; bread fermentation; oats; bioprocessing; malting; iron absorption; mineral bioavailability; phytase activity; phytate;

    Sammanfattning : The effects of bioprocessing on enzymatic phytate hydrolysis in oats were studied during malting, soaking and breadmaking to elucidate the reasons for poor phytase activity in oats and determine the optimal conditions for phytate hydrolysis. Malting of oats in a pilot plant was studied to investigate whether the malting process developed in the laboratory could be used in large scale preparation of oats with reduced phytate content.
