  2. 11. 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.

  4. 12. Reuse and Recycling of Food Packaging - Odour Related Aspects of the Use and Misuse of PET Beverage Bottles

    Author : Heléne Widén; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; aroma transfer; reuse; recycling; migration; contaminants; post consumer material; food packaging; polyethylene terephthalate PET ;

    Abstract : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. READ MORE

  5. 13. Triterpenes and phenolic compounds in apple fruit (Malus domestica Borkh.) : variation due to cultivar, sun exposure, rootstock, harvest maturity, bruising, fungi inoculation, ozone treatment and storage conditions

    Author : Yanrong Lv; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Apple (Malus × domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive triterpenes and phenolic compounds with potentially valuable pharmacological functions. This thesis investigated the effects of pre-harvest and postharvest factors on concentrations of these bioactive compounds in apples. READ MORE

  6. 14. 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. 15. Carbon metabolism in non-conventional yeasts: biodiversity, origins of aerobic fermentation and industrial applications

    Author : Nerve Zhou; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerobic fermentation; carbon metabolism; non-conventional yeasts; strain development;

    Abstract : Abstract: For millennia, the “yeast” Saccharomyces cerevisiae remains by far the most extensively studied and exploited yeast in food and industrial applications. A number of researches and developments have been done since the establishment of the biochemical function of yeast by Louis Pasteur in 1860, however modern lifestyles often connected to food related health trends demand new and innovative food products.
