Fluorescence emission spectra of resveratrol at 25 °C. Resveratrol (in 5 mM phosphate buffer, pH 7.0), was excited at its λmax (adsorption) of 308 and the emission spectra were recorded between 360 and 580 nm. Trace 1: resveratrol alone (5 µM); Trace 2: resveratrol: caprine casein (αs1-II) molar ratio 1:1; Trace 3: resveratrol: caprine casein (αs1-II) molar ratio 1:10; Trace 4: resveratrol: caprine casein (αs1-II) molar ratio 1:20; Trace 5: resveratrol: caprine casein (αs1-II) molar ratio 1:30.
