1. 1. Microbiological hygiene and biological control of leafy green vegetables

   Författare :Elisabeth Uhlig; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Food hygiene; Biological control; Native microbiota; Escherichia coli; Leafy green vegetables;

   Sammanfattning : Fruit and vegetables are vital components of a healthy diet, and international strategies to encourage their consumption are in place (FAO/WHO, 2005). Ready-to-eat (RTE) leafy green vegetable products have exploded in popularity, and are a convenient and attractive way to add greens to the plate. LÄS MER

3. 2. In vitro accessibility of provitamin A carotenoids in vegetables and fruits - Effects of different process and preparation methods and estimation of vitamin A activity

   Författare :Ellen Hedrén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; provitamin A carotenoids; lactic acid fermentation; food matrix; cell wall degrading enzymes; vegetables; vitamin A activity; beta-carotene; red palm oil; fruits;

   Sammanfattning : Vitamin A deficiency is a major nutritional problem in many developing countries, caused chiefly by a diet with low retinol content. The bioefficacy of provitamin A carotenoids in plant foods is claimed to be insufficient to maintain a satisfactory vitamin A status. LÄS MER

4. 3. Nitrate in foodstuffs : analytical standardisation and monitoring and control in leafy vegetables

   Författare :Leonardo Merino; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The potential harm to human health and the environment of compounds derived from nitrate is an issue that occasionally awakens media and public concern. Recent studies provide a new understanding of the role of nitrate and nitrite in our body and motivate revision of the long-held view that nitrate poses a health risk. LÄS MER

5. 4. The role of dietary nitrate in regulation of blood pressure and metabolism

   Författare :Michaela Sundqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A diet rich in vegetables is recommended for health in general and is also associated with lower blood pressure. Research suggests that inorganic nitrate present in leafy green vegetables could be a contributing factor for the favourable effect. LÄS MER

7. 5. Anaemia and iron deficiency in children and women in Tanzania. Effects of dietary iron intake, low iron bioavailability and supplementation with multiple micronutrient beverage

   Författare :Simon Tatala; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serum ferritin; haemoglobin; multiple micronutrient beverage; dietary iron intake; anaemia; serum retinol; iron deficiency; children and Tanzania; pregnant women; iron bioavailability;

   Sammanfattning : Anaemia was investigated in a rural Tanzanian community to determine its magnitude and causative factors in different population groups. Nutritional anaemia resulting mainly from a diet with a low bioavailability of iron affected more than half of the total number of women and children. LÄS MER
