  2. 1. 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

    Author : Generose Ishengoma Mulokozi; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Ellen Hedrén; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Microwave-Assisted Air-Dehydration of Fruits and Vegetables Processing Conditions and Product Quality

    Author : Tomas Funebo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dielectric properties; pre-treatment; dehydration; permittivity; microwave; fruits; vegetables; multimode;

    Abstract : This thesis is focused on aspects of microwave-assisted hot-air drying of fruits and vegetables. The two material coefficients, the relative permittivity (ε) and the loss factor (ε), determine the interaction of microwave energy with foods. READ MORE

  7. 5. Diet, lifestyle, antioxidants, and biomarkers of cancer risk - an epidemiological report from the Malmö Diet and Cancer cohort

    Abstract : This thesis examines associations between a number of epidemiological or biological markers of cancer risk and oxidative stress, in order to achieve a better understanding of how diet, lifestyle, and genetic factors contribute to the occurrence of oxidative stress. Data from the Malmö Diet and Cancer (MDC) cohort was used. READ MORE
