  1. 11. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

    Författare :Gisela Richardson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

    Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

  3. 12. Wetting and Capillary Flow of Surfactant Solutions and Inks

    Författare :Maria von Bahr; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; AKD; ink-jet printing; paper; penetration; absorption; adsorption; hydrophobicity; nonionic; surfactant; spreading; dynamic wetting;

    Sammanfattning : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. LÄS MER

  4. 13. Mesoporous Silica Formed with Triblock Copolymers

    Författare :Katarina Flodström; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; 1H NMR; TEM; SAXS; in situ; mechanism of formation; cubic Ia3d; cubic Im3m; Mesoporous; synthesis; Pluronic; SBA-16; SBA-15; hexagonal p6mm; synchrotron SAXS; Physical chemistry; amphiphilic polymers; silica;

    Sammanfattning : The formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. LÄS MER

  5. 14. Surface modification of cellulose-based fibres for use in advanced materials

    Författare :Simon Utsel; Lars Wågberg; Mikael Lindström; Magnus Norgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Sammanfattning : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibres are combined with different types of polymers.

  7. 15. Milk Genomics – Impact of Genetic Polymorphism on Bovine Milk Composition and Processability

    Författare :Maria Glantz; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; milk genomics; bovine milk; milk composition; technological properties; processability; cheese; quantitative genetic evaluation; single gene effect; genomic selection; genetic polymorphism; leptin; direct genomic value;

    Sammanfattning : Milk genomics is a new area of research that explores the relations between cow genetics and milk characteristics. Identifying the genes controlling compositional and technological traits of milk will give opportunities to select cows for targeted milk production. In this thesis, the impact of different genetic approaches, i.e. LÄS MER
