Comparative study of the characteristics of red Bulgarian and French wines using applied photonics methods

The fluorescence spectra of Bulgarian and French wines of the same price class were obtained at excitation wavelengths of 265 nm, 275 nm and 295 nm. The excitation-emission matrices are obtained and compared. A correlation between the emission maxima and the anthocyanins or the antioxidant activity expressed in Trollox units is obtained.
