We compared the kinetics of adsorption at the air/solution interface of ~-lactoglobulin alone or in mixture with isoamyl acetate at a concentration where it remains water-soluble. Addition of isoamyl acetate to ~-Iactoglobulin, at molar ratios equal to 1 or 2, led to a decrease in the surface tension in the short-time region, but the steady-state value of surface tension was close to that of pre-heated solution of ~-lactoglobulin alone, only for molar ratio equal to 2. Pre-heating mixtures at this molar ratio increased the adsorption kinetics more significantly in comparison with non-heated mixtures and pre-heated pure solutions of ~-lactoglobuline. ln parallel, tryptophan spectrotluori- metric spectra obtained from non-heated or pre-heated solutions indicated in both cases that addition of isoamyl acetate to ~-Iactoglobulin were accompanied by a quenching of fluorescence intensity, while a slight red-shift in wavelength of maximum tluorescence intensity occured only for pre-heated mix- tures. The results were discussed in terms of formation of ~-lg/lAA complexes with a specifie activ- ity at the air/solution interface. © InralElsevier, Paris.
