  2. 11. Short-Chain Fatty Acid Starch Stabilized Pickering Emulsions : Design, Properties and Applications

    Author : Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Short-chain fatty acid starch; Physicochemical properties; Pickering emulsions; Starch modification; Emulsion stability; Starch hydrolysis; In vitro digestion; Lipolysis;

    Abstract : Pickering emulsions are emulsions stabilized by solid particles. Particles with optimal dual wettability toward both of the oil and water phases, can be adsorbed onto the interface, thereby providing the stability of the emulsions. READ MORE

  4. 12. Preparation and Characterization of Chemical Pulps from Wood and Reed Canary Grass

    Author : Helena Håkansson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulping; wood; reed canary grass; acid hydrolysis; microcrystalline cellulose; Chemical Engineering; Kemiteknik;

    Abstract : This thesis presents laboratory results from ethanol pulping of reed canary grass for the production of paper pulp. The focus was on the influence of cooking pa-rameters on the delignification. The strength of the grass pulps was found to be low and the use of such pulps will therefore be limited to a few products. READ MORE

  5. 13. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation

    Author : Venkata Prabhakar Soudham; Jyri-Pekka Mikkola; Christer Larsson; Tom Birger Granström; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

    Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE

  6. 14. Lipid Composition and Deterioration in Light and Dark Muscle of Rainbow Trout (Oncorhynchus mykiss)

    Author : Torbjörn Ingemansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Docosahexaenoic acid; lipid classes; fatty acids; muscle lipids; Palmitic acid; trout; differences; lipids; fish;

    Abstract : Nutritionally valuable lipids, including lipid classes and their fatty acids in light and dark muscle, have been determined and analyzed in farmed rainbow trout. Dark muscle was found to have a higher content of total lipids than light muscle, 7.3 wt% versus 3.0 wt%, which was mostly accounted for by neutral lipids, especially triacylglycerols. READ MORE

  7. 15. Cellulose degradation in pulp fibers studied as changes in molar mass distributions

    Author : Rickard Berggren; KTH; []
    Keywords : cellulose; kraft pulp; birch; spruce; ozonation; acid hydrolysis; degradation; MMD; size-exclusion chromatography; light scattering; molar mass; chain scission;

    Abstract : In this thesis, size-exclusion chromatography (SEC) of woodpolymers dissolved in lithium chloride/N,N-dimethylacetamide(LiCl/DMAc) has been used to characterize the molar massdistributions (MMD) of wood polymers in pulp fibers afterchemical degradation.Characterization of birch kraft pulps subjected to ozonedegradation and acid hydrolysis, respectively, rendereddifferent changes in the MMD.
