1. 1. Solar Assisted Pervaporation (SAP) : A process using membrane pouches and solar energy for the dehydration and preservation of fruit juices in rural and remote areas

   Författare :Randi Phinney; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; membrane; pervaporation; fruit preservation; solar drying; heat and mass transfer; coupling effects;

   Sammanfattning : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on the small-scale for two main reasons. LÄS MER

   Sammanfattning : This study focuses on the fruit of the African medlar (Vangueria infausta L., family Rubiaceae). The investigation included the development of an extraction procedure of volatile components from the fruit matrix, a purification step, separation, identification and quantification. LÄS MER

5. 4. Chemical analysis to promote the use of wild fruits from Mozambique

   Författare :Telma Magaia; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulps; kernels; consumption; fat; protein; minerals; dietary fibre;

   Sammanfattning : Abstract Wild fruit trees have significant cultural and socio-economic value in rural areas of Mozambique. Most of the wild fruits are seasonal and are available mainly in the wet season. Generally they have a short shelf-life and are eaten fresh or after minimal processing; the most common method of preservation is sun-drying. LÄS MER
