    Sammanfattning : 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. LÄS MER

  3. 2. Content and In Vitro Accessibility of Provitamin. A Carotenoids in Some Tanzanian Vegetables and Fruits Effects of Traditional Processing and Preparation, and Influence on Vitamin A Status

    Författare :Generose Ishengoma Mulokozi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; sunflower oil; solar cabinet drying; women; all-trans-beta-carotene; alpha-carotene; open sun-drying; vitamin A; provitamin A carotenoids; plasma; breast milk; fruits; vegetables; red palm oil; Tanzania; beta-cryptoxanthin; pregnancy; children;

    Sammanfattning : Vitamin A deficiency is among the major nutritional problems in Tanzania as in many developing countries. It mainly affects children and pregnant and lactating women. The basic cause of this problem is related to the diet, which contains little preformed vitamin A and plant foods with a low content and bioavailability of provitamin A carotenoids. LÄS MER

  4. 3. Structuring plant cell materials using pre-treatments. Effects on texture and carotenoid accessibility

    Författare :Evelina Tibäck; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PG; degree of methoxylation; texture; carrot; Bostwick consistency index; microstructure; in vitro carotenoid accessibility; PME; tomato; carotenoid content;

    Sammanfattning : A high consumption of fruits and vegetables is considered beneficial and to support good health. To promote higher fruit and vegetable intake, attractive and nutritious fruit- and vegetable-based ready-to-eat products should be available on the market. A key property of an attractive food product is a palatable texture. LÄS MER

  5. 4. Autophagic programmed cell death in the suspensor and endosperm of Vicia faba : An ultrastructural study

    Författare :Ulla Wredle; Björn Walles; Áron Keresztes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Sammanfattning : Programmed cell death (PCD) is a widely spread phenomenon among multi-cellular organisms. Without the deletion of cells no longer needed, the organism will not be able to develop in a predicted way. LÄS MER

  7. 5. Retinal pigment epithelial cells, oxidative stress and lipofuscin : relation to age-related macular degeneration

    Författare :Staffan Sundelin; Stefan Seregard; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In developed countries, age-related macular degeneration (AMD) is the most common cause of loss of central vision in people over the age of 65. The retinal pigment epithelium (RPE) appears to be the site of early pathological changes in AMD. LÄS MER
