    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antioxidant capacity; polyphenolic compounds; anthocyanidins; individual food; meals; ans and stan genes;

    Sammanfattning : Abstract The constant need to improve health and to prevent disease in Bolivia, especially in the Andean region with its extreme environmental conditions (high altitude and lower temperatures), motivated us to extend studies of antioxidant sources in foods and plants, since antioxidants are believed to have major health benefits. Spectrophotometric methods, such as ABTS (2, 2’- azinobis-3-ethylbenzotiazoline-6-sulfonic acid) and FRAP (ferric reduction antioxidant power), were used to evaluate antioxidant activity. LÄS MER

  3. 2. Acrylamide in food products : Identification, formation and analytical methodology

    Författare :Sune Eriksson; Margareta Törnqvist; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acrylamide; food; analytical methods; measurements in air; Environmental chemistry; Miljökemi;

    Sammanfattning : The aim of this thesis was to verify the indicated occurrence of acrylamide formation in heating of food, to identify factors affecting the formation, and to identify important sources of acrylamide exposure from food. As a prerequisite for the studies, gas- and liquid-chromatographic methods with mass spectrometric detection were developed for the analysis of acrylamide in food. LÄS MER

  4. 3. Influences on schoolchildren's dietary selection : focus on fat and fibre at breakfast

    Sammanfattning : One important aim of the Swedish Action Programme for Nutrition is to increase the consumption of dietary fibre and decrease fat intake. The currently available extensive range of fat-reduced and fibre-enriched foods makes these dietary practices possible, but also makes the selection of a health promoting diet more complex. LÄS MER
