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

    Author : Anton Bengtsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Anton Bengtsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

    Abstract : Carotenes are a group of fat-soluble pigments in many fruits and vegetables associated with several important biological effects, like protection against the development of some forms of cancer and cardiovascular disease. The carotene bioavailability in plant foods, i.e. READ MORE

  6. 4. Nutritional Value and Quality of Processed Mango Fruits

    Author : Isabel Guiamba; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidification; ascorbic acid oxidase; polyphenoloxidase; water blanching; β-carotene; osmotic dehydration; infrared heating; microwave heating; Mango; EDTA; vitamin C;

    Abstract : Mango (Mangifera indica L.) is one of the most important tropical fruits commercialized and consumed worldwide, and an excellent source of fibre, bioactive compounds such as pro-vitamin A carotenoids, vitamin C (ascorbic acid) and phenolics. Mango was used in this thesis as a model fruit of fruits and vegetables that are rich sources of nutrients. READ MORE

  7. 5. α-tocopherol and β-carotene in forages and their utilisation by dairy cows in organic production

    Author : Hanna Lindqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : There are large variations in α-tocopherol (vitamin E) and β-carotene (pro-vitamin A) concentrations in forages. α-Tocopherol and β-carotene are antioxidants and important for the health and fertility of cows. READ MORE
