  2. 11. Aroma Partition and Release from Soft Drinks, Jam, and Jellied Sweets

    Author : Annika Hansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas chromatography; aroma; gel; model mouth; partition coefficient; release; citric acid; pectin; in-nose; sugar; proton-transfer reaction mass spectrometry; soft drink;

    Abstract : The research described in the present thesis was focused on the influence of food ingredients and structures on the partition and release of aroma compounds from model systems such as soft drinks, jam, and jellied sweets. The effects on aroma release were studied during both static and dynamic conditions, the latter by both model mouth and in-nose measurements. READ MORE

  4. 12. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

    Author : Anna Karin Morén; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

    Abstract : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. READ MORE

  5. 13. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Author : Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Abstract : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. READ MORE

  6. 14. Diffusion studies in gels using holographic laser interferometry

    Author : Charlotte Mattisson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

  7. 15. Polymer extraction and utilization of brown algal biomass

    Author : Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. READ MORE
