Foods are complex multi-component systems which are composed of volatile and non-volatile substances. The flavour profile of a food is an important criterion for the selection of our foodstuffs. The main objective of this study was the clarification of the complex relationships of the flavour release as a function of the composition of the food matrix at molecular level. Therefore the influence of matrix effects onto the odorants partition coefficients in oil-water model systems and a custard sample were investigated. The studies included a series of lactones, ester and alcohols (gamma- and delta-octalactone, gamma- and delta-nonalactone, gamma- and delta-decalactone, ethyl hexanoate, 3-methyl-1-butanol and 2-phenylethanol). The partition coefficients were determined using static headspace gas chromatography (SH-GC). The results indicated that the custard/air partition coefficients of selected odorants are located between the water/air- and miglyol/air partition coefficients. Furthermore the mass transfer rates of selected odorants were investigated in custard- and milk powder-water samples. The values of the mass transfer rate were found higher in milk powder/water systems than in custard model. Nevertheless the results indicated that the viscosity of the matrix did not significantly influence the values of mass transfer rate of selected flavour compounds.

Efficient routes to the synthesis of norbornadiene-tethered nitrones have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in moderate to good yields for a variety of substrates and were found to be highly regio- and stereoselective, giving single regio- and stereoisomers in most cases.

When NiCl2·6H2O reacts with the non-steroidal anti-inflammatory drug flufenamic acid (Hfluf), complex [Ni(fluf-O)2(MeOH)4], 1 was isolated. When the same reaction takes places in the presence of a N,N?-donor heterocyclic ligand 2,2?-bipyridylamine (bipyam), 2,2?-bipyridine (bipy) and 1,10-phenanthroline (phen), the complexes [Ni(fluf-O,O?)2(bipyam)], 2, [Ni(fluf-O)2(phen)(MeOH)2], 3 and [Ni(fluf-O)2(bipy)(MeOH)2], 4 were isolated, respectively. Complexes 1-4 were characterized by physicochemical and spectroscopic techniques and the crystal structure of complex 2 was determined by X-ray crystallography. The interaction of the complexes with serum albumins was investigated by fluorescence emission spectroscopy and the corresponding binding constants were calculated. UV-Vis spectroscopy, viscosity measurements and fluorescence emission spectroscopy for the competitive studies of the complexes with ethidium bromide were the techniques used in order to investigate the interaction of the complexes with calf-thymus DNA; intercalation was revealed as the most possible mode of DNA-binding.
