  1. 1. Molecular Exchange in Colloidal Dispersions

    Författare :Alex Evilevitch; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

    Sammanfattning : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. LÄS MER

  3. 2. Lecithin-Based Microemulsions for Pharmaceutical use - Phase behavior and Solution Structure

    Författare :Christian von Corswant; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; felodipine; solubilization; drug delivery; self-diffusion NMR; alkylmaltoside; microstructure; isopropyl myristate; triglyceride; soybean phosphatidylcholine; Microemulsion; lecithin; Livsmedelsteknik;

    Sammanfattning : Microemulsions are thermodynamically stable, transparent solutions of water, oil and amphiphile(s). It is possible to incorporate large amounts of oil in microemulsions, which makes them interesting for use as a drug delivery vehicle for water insoluble drugs. A prerequisite for pharmaceutical use, however, is a low toxicity of the composition. LÄS MER

  4. 3. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants

    Författare :Sofia Marmon; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precipitation; acid; gelation; in vitro digestion; solubilization; herring; protein; salt solubility; pH; lipids; alkaline; transmission electron microscopy; dioxins;

    Sammanfattning : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. LÄS MER

  5. 4. Surfactants based on natural products - enzymatic synthesis and functional characterization

    Författare :Fredrik Viklund; KTH; []
    Nyckelord :Enzymatic synthesis; Surfactants; Antioxidants; Ascorbyl oleate; Polyethylene glycol PEG esters; Hemolysis; Transepithelial electrical resistance; Ionic liquids; Candida antarctica lipase B;

    Sammanfattning : Surfactants are molecules that contain a water-soluble and afat-soluble part. They have important functions in productssuch as detergents, cosmetics, pharmaceuticals and foods aswell as in many industrial processes. Surfactants are used onvery large scale, which makes it important to decrease theirimpact on the environment. LÄS MER
