  1. 1. Nanorheological Studies of Caseins

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Frida Gustavsson; Livsmedelsteknik; []
    Nyckelord :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;

    Sammanfattning : 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. 3. Competitive Protein Adsorption during Spray-drying

    Författare :Karin Landström; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; pyrene; quenching; fluorescence; beta-casein; beta-lactoglobulin; bovine serum albumin; milk proteins; Spray-drying; competitive adsorption; Surface and boundary layery chemistry; Ytkemi; gränsskikt;

    Sammanfattning : The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. LÄS MER

  5. 4. Evaluation of UHT milk processed by direct steam injection and steam infusion technology

    Författare :Bozena Malmgren; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sedimentation; gel formation; microstructure; TEM transmission electron microscopy; immunogold labelling; heat effects; Technological sciences; Teknik; Food and drink technology; Livsmedelsteknik; proteolysis; steam infusion; UHT milk; steam injection;

    Sammanfattning : UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity.

  7. 5. Variation in raw milk quality : impact on milk coagulation and cheese ripening

    Författare :Hasitha Priyashantha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis examined some of the causes behind recent increasing variation in ripening time of a traditional, Swedish long-ripening hard cheese. Variations in the composition and properties of farm and dairy silo milk intended for production of the long-ripening cheese were recorded during one year, and the resulting cheese was characterised.
