  1. 1. Starch Pickering Emulsions : Process and Encapsulation Stability

    Författare :Ali Marefati; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Sammanfattning : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. LÄS MER

  3. 2. Exploring functionalization of colloidal silica for nanoparticle-stabilized emulsions

    Författare :Sanna Björkegren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermo-responsive emulsions; functionalized colloidal silica; Pickering emulsions; NMR spectroscopy; surface activity; clouding;

    Sammanfattning : The main objective of this thesis was to evaluate how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-dispersed silica nanoparticles were functionalized with hydrophilic and hydrophobic groups. LÄS MER

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

    Författare :Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Functionalization and characterization of aqueous silica sols and their application in Pickering emulsions

    Författare :Sanna Björkegren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pickering emulsions; functionalized colloidal silica; surface activity; NMR spectroscopy;

    Sammanfattning : The main objective of this thesis is to create an understanding of how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-based silica sols have been functionalized with hydrophilic and hydrophobic groups. LÄS MER

  7. 5. Starch stabilized Pickering emulsions : Colloidal starch particles and their effects on emulsion properties

    Författare :Hisfazilah Saari; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :Starch granules; Pickering emulsions; colloidal particles; sedimentation; acid hydrolysis; cold gelatinization; dissolution; non-solvent precipitation; nanoparticles;

    Sammanfattning : Particles can be used to stabilize multi-phase systems known as Pickering emulsions. The aim of this thesis was to investigate how starch particles affect emulsion properties. Starch granules were used individually as well as in binary mixtures. LÄS MER
