  1. 6. Modelling and Optimisation of Integrated Biotechnical Processes -Application to the Fermentative Production of Lactic Acid from Wheat Flour

    Författare :Christina Åkerberg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; economy; wheat flour; starch; lactic acid; kinetics; simulation; modelling; optimisation; Kemiteknik och kemisk teknologi;

    Sammanfattning : Biotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling.

  3. 7. Fermentation as a Means of Optimizing the Glycaemic Index - Food Mechanisms and Metabolic Merits with Emphasis on Lactic Acid in Cereal Products

    Författare :Elin Östman; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nutrition; starch; healthy human; fermentation; lactic acid; sourdough; cereal products; milk; glycaemic index; bread; Näringslära; diabetes; insulin response;

    Sammanfattning : In current recommendations from FAO/WHO, foods that elicit low glycaemic responses and thus have low glycaemic indices (GIs) are advocated. The rationale for this recommendation is that low-GI diets have been shown to reduce risk factors for e.g. type II diabetes and cardiovascular disease. LÄS MER

  4. 8. Graphene Oxide Technology to Advance the Performance of Poly(lactic acid) Materials

    Författare :Huan Xu; Minna Hakkarainen; Jean-Marie Raquez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Poly lactic acid ; Graphene Oxide; Stereocomplex; Nucleation Mechanism; Crystalline Morphology; Filler Structure; Mechanical Properties; Gas Barrier; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : In the past two decades, a burgeoning biorefinery concept has grown in concert with the materials science, contributing to the rise of biobased materials that respect environment and are versatile for various applications. An excellent example is poly(lactic acid) (PLA) that exhibits high strength and desirable degradability. LÄS MER

  5. 9. Properties of poly(lactic acid) in presence of cellulose and chitin nanocrystals

    Författare :Shikha Singh; Kristiina Oksman; Maria Lluisa Maspoch; Alfonso Jiménez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly lactic acid ; chitin nanocrystals; nanocellulose; crystallization; orientation; nanocomposites; mechanical properties-other properties; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Plastic based materials are widely used for industrial and domestic packaging application. However, disposal of such petroleum-based materials e.g. polyethylene (PE), polypropylene (PP), and polyethyleneterephthalate (PET) has become a huge threat to the environment. LÄS MER

  7. 10. Lactic acid bacterial symbionts from the honeybee: Characteristics and applications in wound management

    Författare :Éile Butler; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wound management; honey; extracellular proteins; bioactive substances; honeybee; Lactic acid bacteria;

    Sammanfattning : Antibiotic resistance is now a large threat with worldwide agreement that we will fall into a post-antibiotic era unless there is suitable treatment alternatives discovered. In recent years, chronic wounds have become a major burden on society and treatment is complicated. LÄS MER
