2. 21. Exploring Coagulation Properties in Bovine Milk Using Milk Genomics Approaches

   Author : Frida Gustavsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bovine milk; rennet-induced gelation; milk genomics; Swedish Red dairy cattle; milk composition; technological properties; cheese; genetic polymorphism; quantitative trait locus; protein profile; casein micelle; calcium content;

   Abstract : Swedish Red (SR) dairy cattle is the second most common breed in Sweden and hence SR milk quality is crucial for the nutritional value and the processability of the milk delivered to the Swedish dairies. This thesis will give an insight into the quality of milk from SR cows and it will illuminate the possibilities for improvements of both breeding programs and the quality of different dairy products, focusing on cheese characteristics.

4. 22. Biodegradable Surfactants Containing Hydrolyzable Bonds

   Author : Maria Stjerndahl; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; amide; alkaline hydrolysis; cleavable surfactant; carbonate; ester; biodegradation; CMC; enzymatic hydrolysis; mixed micelle;

   Abstract : Surfactants with built-in weak bonds, so-called cleavable surfactants, are interesting candidates in the search for more environmentally friendly alternatives to traditional surfactants. The objective of this thesis was to perform a systematic study in which cleavable surfactants with different hydrolyzable bonds were compared with regard to physicochemical properties, and chemical and biological stability.

5. 23. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

   Author : Caroline Ericsson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; peptide stabilisation; solubilisation; micelle morphology; solid-state behaviour; alkylglycosides; nonionic surfactants;

   Abstract : A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

6. 24. Nanorheological Studies of Caseins

   Author : Kristina Helstad; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; Casein micelle; Caseins; Nanorheology;

   Abstract : To be able to improve the quality of dairy products and dairy processes, knowledge of casein molecules, casein micelles and casein aggregates is important. The rheological properties of casein products, casein gels and adsorbed layers of casein, have been widely investigated. READ MORE

7. 25. Phase Behavior and Solution Properties of Aqueous Polyion-Surfactant Ion Systems

   Author : John Janiak; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer-surfactant association; complex salt; nonionic surfactant; poly acrylic acid ; poly methacrylic acid ; copolymer; polymeric counterion; decyl betainate; phase behavior; solubilization; mixed micelle; hydrolysis; release; liquid crystal; nanoparticles; thermosresponsive; C12E8; C12E5;

   Abstract : Polyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple counterions present).
