  1. 6. Food and Packaging Interactions Affecting Food Quality

    Författare :Fredrik Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sorbed vegetable oil; oxygen transmission rate; food packaging; supercritical fluid extraction; inertness test; refillable PET bottles; permeability; aroma; interactions; sorption;

    Sammanfattning : Food and packaging interactions that may impair the food quality have been studied and methods to determine these interactions have been developed. An off-line supercritical fluid extraction method using carbon dioxide was developed and used to extract sorbed low molecular weight compounds from polymer films. LÄS MER

  3. 7. Quality Aspects of Modified Atmosphere Packaged Broccoli

    Författare :Annelie Jacobsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; heat transfer; mass transport; quality; flavour; aroma; modified atmosphere packaging; broccoli;

    Sammanfattning : The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package.

  4. 8. Development of Accurate Reduced Order Models in a Simulation Tool for Turbomachinery Aeromechanical Phenomena

    Författare :Mauricio Gutierrez Salas; Björn Laumert; Paul Petrie-Repar; Damian Vogt; Carlos Martel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; forced response; high cycle fatigue; reduced order models; ROM; craig-bampton; mistuning; tuned; mistuned; cyclic; noncyclic; craig-chang; free-interface. fixed-interface; subset nominal mode; SNM; CBMS; CCMS; CCC; CBC; FEM; CMS; modal; eigen; modeshapes; aeroelasticity; aeromechanical; tool; turbomachinery; turbine; compressor; AROMA; Energy Technology; Energiteknik;

    Sammanfattning : Modern gas turbines are still vulnerable to vibrations when operated at certain speeds. This unstable environment can lead to high cycle fatigue (HCF) and damage several of the components inside the turbine. LÄS MER

  5. 9. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

    Författare :Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. LÄS MER

  7. 10. Aroma components in Vangueria infausta L. : Characterization of components using GC_MS and aroma loss during drying

    Författare :Rui Ráice; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; encapsulation.; threshold; drying; volatiles; vangueria infausta;

    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
