  2. 21. Aroma characterisation and retention after heat treatment and drying of fruits using extraction and GC-MS analysis

    Author : Rui Ráice; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fruits; Vangueria infausta; Mangifera indica; volatile; aroma; blanching; drying; encapsulation; modelling; GC-MS.;

    Abstract : This study concerns the identification and characterisation of volatile components of fruits, and evaluation of the effect of heat treatment and drying on retention or loss of volatiles of fruits. The investigation included developing a procedure to extract volatile components from the fruit matrix, a purification step, separation, identification and quantification. READ MORE

  4. 22. Utilizing lignocellulose-based building blocks to develop recyclable polyesters

    Author : Nitin Valsange; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biobased; Polyester; Recycling;

    Abstract : With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. READ MORE

  5. 23. Ultrastructure of the wood cell wall

    Author : Jonas Hafrén; KTH; []
    Keywords : ;

    Abstract : The ultrastructure of wood fibres has been studied incambial cells, differentiating fibres and mature xylem fibres,using the Rapid-Freeze Deep-Etching (RFDE) technique combinedwith transmission electron- and epifluorescence microscopy.Pectin distribution in mature wood fibres, and in fibres duringdevelopment, have been studied by immunolabelling.

  6. 24. Atom transfer radical polymerization from multifunctional substrates

    Author : Anna Carlmark; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : Atom transfer radical polymerization (ATRP) has proven to be a powerful technique to obtain polymers with narrow polydispersities and controlled molecular weight. It also offers control over chain-ends. READ MORE

  7. 25. Physicochemical properties of root fiber suspensions. A comparison between parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius)

    Author : Alejandra Castro; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; parsnip; yacon; plant suspensions; particle size distribution; rheology; fructans; dietary fiber;

    Abstract : The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in these two roots, and possibly encourage their further industrial use.
