1. 1. Association between technological properties of bovine milk, cold induced depletion and genetic variants of β- and κ-casein

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Simon Tobias Höxter; [2023]
   Nyckelord :Milk proteins; casein micelle; β-casein depletion; micelle size; milk coagulation properties Swedish;

   Sammanfattning : Caseins (CN) represent about 80% of the total protein in bovine milk and are of major importance in dairy production. The four casein types, i.e., αs1-, β-, αs2-, and κ-casein are in turn divided into different genetic variants. LÄS MER

3. 2. Impact of storage at freezing temperatures on casein micelle size, coagulation properties and curd yield in bovine milk

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Ebba Bondesson; [2022]
   Nyckelord :Casein micelle size; milk coagulation time; gel strength; curd yield; freezing; freeze drying;

   Sammanfattning : Frozen storage is an efficient and convenient way to preserve and transport milk, but the effect from frozen storage needs to be further researched. The objective of this study was to investigate how storage at freezing temperatures (-80°C and -20°C) of frozen and freeze-dried bovine milk samples, respectively, affects pH, casein micelle size, ethanol stability, rheological properties and curd yield.

4. 3. Variation in protein profile of bulk milk from Northern Sweden

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Therese Schönborg; [2020]
   Nyckelord :Mountain Breed; Swedish Jersey; Swedish Red and white; Swedish Holstein; Capillary Electrophoresis; protein composition;

   Sammanfattning : The protein composition of milk samples from Norrland, Sweden was investigated by capil-lary electrophoresis, in order to evaluate the variation in protein profile from different breeds at different collection periods during the year. The protein profile is of importance for pro-cessability of the milk, and is known to be influenced partly by genetics. LÄS MER

5. 4. The influence of molecular structure of phospholipids on the transition from micelles to bilayers in bile salt surfactant/phospholipid mixtures

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för läkemedelskemi

   Författare :Zeyneb Alkademi; [2020]
   Nyckelord :phospholipids; micelles; bilayers; bile salt; surfactant;

   Sammanfattning : Phospholipid molecules self-assemble to form bilayers that are poorly soluble in an aqueous solvent. Phospholipids may, however, be readily dissolved by mixing with a bile salt or amphiphilic drug surfactant that forms mixed surfactant/phospholipid micelles. LÄS MER

7. 5. A novel chitosan-stearic coating with bee-pollen microcapsules for corrosion protection

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Albin Andersson; [2020]
   Nyckelord :;

   Sammanfattning : In this project a novel chitosan-stearic acid (CS-SA) coating with bee-pollen microcapsules for encapsulation of 2-mecraptobenzothiazole (MBT) as a waterborne formulation for a biocompatible corrosion protection coating was developed and the coating properties was analyzed. Hydrophobic stearic acid (SA) was crosslinked with via a carbodiimide reaction to form micelles and is assembled on the bee- pollen grains and the chitosan matrix was further self-crosslinked using glutaraldehyde (GA).
