  1. 1. Provitamin A Carotenoids in Orange-Fleshed Sweet Potato

    Författare :Anton Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; orange-fleshed sweet potato; food processing; high-performance liquid chromatography; β-carotene; β-carotene uptake; Caco-2 cells; provitamin A carotenoids; vitamin A deficiency; iron;

    Sammanfattning : Vitamin A deficiency is a major nutritional disorder in a large number of developing countries. The disorder is mainly caused by an inadequate intake of preformed vitamin A and provitamin A carotenoids from the diet. It is also recognized that vitamin A deficiency and iron deficiency tend to coexist in many population groups. LÄS MER

  2. 2. Improving vitamin A nutrition in low-income countries. In vitro bioaccessibility of provitamin A carotenoids in biofortified orange-fleshed sweet potato

    Författare :Anton Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioaccessibility; β-carotene; biofortification; provitamin A carotenoids; coherent anti-Stokes Raman scattering microscopy; vitamin A deficiency; food processing; orange-fleshed sweet potato; in vitro digestion; Caco-2 cells;

    Sammanfattning : Vitamin A deficiency is a major nutritional disorder in a large number of low-income countries that is caused by an inadequate intake of preformed vitamin A and provitamin A carotenoids in the diet. The objective of the present thesis was to evaluate orange-fleshed sweet potato (OFSP) as a biofortified food source of provitamin A carotenoids with a potential to be included in a diet for alleviating vitamin A deficiency.
