Scientific tasks are primarily placed within the oxidation area where model studies are used to describe the mechanisms behind oxidation processes in proteins as well as in protein-/lipid models. The models are particularly used to study how oxidation affects the protein structure and how the protein structure influences different oxidation processes (e.g. light, enzymes and transition metal ions). Accessibility of proteases is also used as a measurement of changes of the protein structure (at primary and higher protein structure levels) after oxidation. Knowledge from model studies is carried on to dairy products such as milk, powder and cheese where the oxidation processes are described as direct measurement of primary oxidation products (e.g. free radicals and protein and lipid peroxides) and also secondary oxidation products (e.g. dityrosine, protein carbonyl at amino acid level and lipid carbonyls).



Mass spectrometry (Ion-trap, MALDI ToF-ToF and GC-MS), spectroscopic methods (electron spin resonance (ESR/EPR) fluorescence spectroscopy and circular dichroism (CD)) as well as different separation techniques (reverse phase, gel filtration, ion exchange, etcetera) are used in this research.
