  2. 1. Optimisation and modelling of aroma recovery by pervaporation

    Author : Jenny Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; optimisation; mass transfer; modelling; pervaporation; aroma recovery; Livsmedelsteknik;

    Abstract : During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. READ MORE

  4. 2. Mass transport mechanisms and module design aspects in the recovery of dilute volatile organic compounds by hydrophobic pervaporation

    Author : Olivera Trifunovic; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; Aroma recovery; Module design; Hydrophobic pervaporation; Mass transport;

    Abstract : Hydrophobic pervaporation has gained a lot of attention as an alternative process for mild aroma recovery, but the real commercial applications of this process are still in their infancies. Better understanding of mass transport phenomena in composite pervaporation membranes is essential from the point of view of membrane manufacturing, while process simulation is an important tool for predicting pervaporation module performance.

  5. 3. Extraction and chromatography of bioactive compounds in complex samples using supercritical CO2 technology

    Author : Said Alhamimi; Centrum för analys och syntes; []
    Keywords : Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

    Abstract : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. READ MORE
