  2. 16. 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

  4. 17. Climate-induced changes : Its effects on plankton food webs from the Baltic Sea
