Analyis of oxygenated egg lipids in tempera paint by MALDI FT-ICR-MS(MS)
Egg was deposited on carrier material and exposed to high intensities of visible light. Comparison of the MALDI-FT-MS spectra of light aged sample with a control (unexposed) sample showed the formation of compounds 16 amu higher than peaks depleted upon light ageing. The high resolution FTMS data allowed determination of the exact elemental composition of the lipid alteration products, and unambiguously showed incorporation of oxygen. SORI CAD was used to analyse the structure of one of the oxidation products and it was determined to which fatty acid residue the oxygen had been introduced.
